Mesh Wi-Fi Systems 101: The Best Tips

Mesh Wi-Fi Systems 101: The Best Tips

Posted on

You must have heard of “mesh,” “Wi-Fi system,” or “mesh Wi-Fi system,” and might even have some idea of what they are. OK, they are the same thing. But there’s more than just semantics in this post.

You’ll learn all about this type of Wi-Fi solution, including when it’s not a mesh and how to build an optimal one for your home. Sometimes, the little things I mention here can make a huge difference.

By the way, let’s face it! Similar to the case of getting a single router, only you would know which mesh system fits you best — you’re the one who lives in your home and knows what you need. All I can do is lay out the facts and hopefully point you in the right direction.

Dong’s note: I originally published this piece on April 28, 2018, and updated it on February 1, 2023, with up-to-date information.

Mesh Wi-Fi network explained: It’s more than lumping a bunch of routers together

Mesh has been around for a long time, but it became a big deal when a company named eero — all lowercase — announced the original eero Wi-Fi System in February 2016.

Since then, there’s been a home mesh revolution with Wi-Fi systems from virtually all networking vendors. I detailed that in this brief history of popular mesh brands.

Popular home mesh brands: Their similarities and differences

A mesh Wi-Fi system has more names than those mentioned above, but “mesh” is a short and sweet moniker. I like it.

A mesh consists of multiple hardware Wi-Fi broadcasters (routers, access points, extenders, etc.) that work together to form a single unified Wi-Fi network. We’ll get them soon below.

The reverse might not be true, however. Just because you have multiple Wi-Fi broadcasters in a single network doesn’t necessarily mean you have a mesh system.

But first, let’s find out when a mesh system is necessary.

When do you need a mesh?

And generally, it’s best to have just one broadcaster (typically a Wi-Fi router) to avoid interference. But in many large places, one router doesn’t provide enough Wi-Fi coverage. And that’s when we need a mesh system.

In other words, as for as Wi-Fi is concerned, more hardware is not necessarily better. A mesh is not an upgrade to a single broadcaster — it’s a necessary alternative.

Besides the coverage, a Wi-Fi system doesn’t solve any problems you might have with a single router with the same specs and feature set. And using multiple broadcasters in close proximity can be a bad thing.

It’s hard to say precisely when a mesh is in order. Generally, if your place is 1800 ft2 (167 m2) or smaller, you probably only need a single broadcaster. More specifically, a standalone Wi-Fi router placed near the center is better than getting a mesh.

But this depends a lot on the layout of your home, the number of walls, where you place a broadcaster, etc.

So, think of a mesh when there are areas in your home the current Wi-Fi broadcaster can’t reach. I will talk more about the necessary hardware units below.

Wi-Fi routers explained: How to pick that perfect one

What constitutes a mesh network

You need at least two hardware units to form a mesh — many canned systems are available as a 2-pack.

One acts as the router and connects to the Internet, and the other links to the first one — wirelessly or via a network cable — to extend the Wi-Fi coverage.

These hardware units are called different things by different vendors, such as base stations, access points, nodes, satellites, hubs, mesh points, Wi-Fi points, routers, etc.

For simplicity, let’s call them all hubs in this post. So a mesh system will include a primary hub (router) and one or more satellite hubs. What link them together is the backhaul connection.

Backhaul vs fronthaul

A Wi-Fi connection between two direct devices occurs in a single band, using a fixed channel, at any given time.

Generally, when you use multiple Wi-Fi broadcasters — in a mesh network or a combo of a router and an extender — there are two types of connections: fronthaul and backhaul.

Fronthaul is the Wi-Fi signals broadcast outward for clients or the network ports for wired devices. It’s what we generally expect from a Wi-Fi broadcaster.

On the other hand, backhaul, a.k.a backbone, is the link between one broadcaster and another, be it the main router, a switch, or another satellite hub.

This link works behind the scene to keep the hardware units together as a system. It also determines the ceiling bandwidth (and speed) of all devices connected to the particular broadcaster.

Dual-WAN: Where the distinction between bandwidth vs speed is clear

When a Wi-Fi band handles backhaul and fronthaul simultaneously, only half of its bandwidth is available to either end. From the perspective of a connected client, that phenomenon is called signal loss.

When a Wi-Fi band functions solely for backhauling, it’s called the dedicated backhaul.

In a mesh system, only traditional Tri-band hardware — those with an additional 5GHz band — can have a dedicated backhaul band without ostracizing clients of the same band.

Generally, it’s best to use a network cable for backhauling — wired backhauling. And that’s an advantage of mesh hardware with network ports. In this case, a hub can use its entire Wi-Fi bandwidth for front-hauling.

In networking, network cables are always much better than wireless in speed and reliability.

The most important requirement to have a mesh is the involved Wi-Fi broadcasters work together to form a single seamless network, and users can manage all of them in one place via a single web interface or mobile app.

If you have to manage any hardware piece separately, it’s not part of a mesh. Below are examples of popular Wi-Fi hardware that doesn’t immediately turn your network into a mesh when used.

Non-mesh Wi-Fi broadcasters: Extenders vs access points

A mesh system consists of multiple broadcasters that work together and can be managed in one place such as a mobile app or the web user interface of the router unit.

In a mesh with wireless backhauling, each satellite unit of the system is essentially a system-wide managed Wi-Fi extender.

In a mesh with wired backhauling, each satellite unit of the system is essentially a system-wide managed access point.

But using multiple individually managed extenders or access points in a network is not ideal from the management’s perspective. You’ll generally experience no sealless handoff and inevitable slow performance in the extenders’ case.

That said, you should never expect excellent performance or long-term ease of use when using an extender in your network. It’s a quick and dirty fix that works to only some extent and will likely break the moment you change your Wi-Fi settings (SSID, password, etc.)

On the other hand, when set up correctly, a combo of a router plus a couple of access points can work similarly to a wired mesh system in terms of performance and handoff. An access point always delivers better performance than a wireless mesh of the same Wi-Fi standard and tier.

How a mesh Wi-Fi network is better than non-mesh hardware

A mesh Wi-Fi network has three clear advantages over extenders or access points.

1. Ease of use

A Wi-Fi system is easy to set up. At most, you only need to set up the primary hub (the router). After that, the rest of the satellite hubs will replicate the Wi-Fi settings and expand the coverage.

That’s the case in the ongoing management, too. For example, you only have to do that on the router unit when you need to change Wi-Fi settings, such as the network name (SSID) or password. The system will apply that to the satellites automatically.

2. Seamless hand-off

In a mesh, it’s easier to have continuous connectivity on your device when roaming from one hub to another, as though there was just one hub involved.

Specifically, as you roam around within a mesh’s Wi-Fi coverage, the device in your hand will automatically switch to the broadcaster with the best signals.

By the way, signal hand-off works band per band and doesn’t require Smart Connect, where you name all bands as a single network (SSID).

The seamless hand-off also applies to satellite hubs when two or more satellites are in a wireless setup.

In this case, a satellite will automatically pick which hub to form the backhaul link, depending on the real-time condition. For this backhaul link, the satellite behaves like any “client.”

Extra: Notes on the seamless hand-off

It’s important not to take seamless literally. That doesn’t exist.

Physically, the client needs to disconnect itself from one hub and move to another, and there’s always a brief interruption during the process — it’s a matter of how quickly. It’s seamless when it happens so fast that you don’t notice it.

But generally, you will always notice the interruption if you use real-time communication apps — like Wi-Fi calling or video conferencing. In this case, pick a location with strong signals and stay there.

However, if you stream a video or do general web surfing, file downloading, etc. The transition can appear seamless.

A few things to keep in mind:

  • For seamless hand-off to work, involved hardware devices on both sides (hubs and clients) must support the IEEE 802.11r, 802.11v, or 802.11k standard.
  • Most Wi-Fi systems and clients support at least one standard above, but there’s a chance they don’t feature the same one, so seamless hand-off is not a sure thing. In this case, turning Wi-Fi off and back on, or disconnecting and then reconnecting to the SSID, is the sure way for the client to connect to the best mesh hub.
  • It’s the speed that matters. If your connection is fast enough for your task, there’s no need to be concerned about which node your device connects to.
  • Wi-Fi doesn’t follow human logic in terms of distances. Within a certain range where signals are consistently strong (or weak) to a certain extent, devices might not see anything better or worse between closer or farther broadcasters.
  • Oversensitive hand-off can be bad since constant jumping from one hub to another will cause unstable connectivity.

In my experience, via testing hundreds of hardware devices, the seamless hand-off is almost always hit or miss. It varies depending on your existing router, clients, and other factors.

Most Wi-Fi mesh hardware uses the connection speed as the base for the hand-off.

Specifically, a client would consider jumping from one broadcaster to another only when the connection speed between it and the current broadcaster is no longer fast enough for its general bandwidth needs.

Depending on the situation and varying by hardware or Wi-Fi standard, this threshold tends to be relatively low, like 50Mbps, because most clients generally don’t need more than that in real-world usage.

In any case, this is the reason why in specific mesh setups, devices are more clingy to a far mesh node — they don’t reach the speed threshold required for the jump yet.

3. Better performance

All the hubs work together as a single unified Wi-Fi network in a mesh. As a result, they leverage one another’s Wi-Fi signals to deliver the best efficiency instead of working independently.

For this reason, a mesh will also have better performance and reliability than using a bunch of extenders together.

Note that using network cables to link the hubs — or wired backhauling — is the best way to build the best-performing mesh Wi-Fi system.

Wireless connections are temperamental.

Signal loss: The biggest drawback of Dual-band (or Tri-band Wi-Fi 6E) wireless mesh

There’s always signal degradation due to distance or interference when wirelessly linking Wi-Fi broadcasters together. And, if you use dual-band hardware, there’s also signal loss.

That’s when a satellite hub’s wireless band receives and rebroadcasts Wi-Fi signals at the same time. Having to do two things simultaneously, the band has at most only 50 percent of its bandwidth on either end.

It’s important to note that the bandwidth is shared no matter how strong the signals are. Consequently, the full-bars Wi-Fi signal on a client represents only half the broadcaster’s bandwidth. In reality, the actual bandwidth after overhead will be even lower.

Specifically, in a dual-stream (2×2) Wi-Fi 6 system, such as the TP-Link Deco X60, we can reasonably expect each hub to deliver the theoretical speed of up to 1200Mbps on the 5GHz band (that’s 80MHz channel bandwidth).

A 5GHz client connected to a satellite hub will get only 600Mbps from it at most, or half the speed, compared to when it connects to the primary hub (the router). And if you have multiple clients connected to the satellite, all of them will share this reduced bandwidth which, at best, is limited by the backhaul connection.

The speed numbers above are theoretical. In real-world usage, due to distance, interference, and additional overhead, the actual sustained rates will be markedly lower.

For this reason, avoid using cheap extenders of slow Wi-Fi standards since, after the signal loss, the actual Wi-Fi speed will be too sluggish to be useful.

To fight signal loss, networking vendors use hardware with an additional 5GHz band (5GHz + 5GHz + 2.4GHz).

Netgear is the pioneer on this front with its Orbi product line, which dedicates the second 5 GHz band to backhauling. This type of dedicated backhaul allows the other two bands to focus on serving clients.

Even then, you still have to deal with the fact Wi-Fi signals get weaker over the range. So, the best way to combat signal loss and degradation in a wireless configuration is to set up your system correctly.

Extra: Mesh Wi-Fi network and Wi-Fi 6E

Starting in 2021, we have new hardware that supports Wi-Fi 6E.

Here’s what Wi-Fi 6E is without the hype

Wi-Fi 6E has a new 6GHz band. As a result, for compatibility reasons, all of its hardware (broadcasters and clients) will come with three bands, including 2.4GHz, 5GHz, and 6GHz. It’s a new type of Tri-band instead of the traditional Tri-band (2.4Ghz + 5GHz + 5Ghz).

Having three different bands, a Wi-Fi 6E broadcaster is not better than a Tri-band Wi-Fi 6 counterpart in a wireless mesh configuration — it has no extra band working as the dedicated backhaul.

In other words, a Tri-band Wi-Fi 6E mesh is similar to a Dual-band Wi-Fi 6 or Wi-Fi 5 counterpart in terms of wireless backhaul link. Consequently, a Tri-band Wi-Fi 6E mesh system also suffers greatly from signal loss.

And that has proved to be the case in real-world testing. Check out the reviews of Wi-Fi 6E mesh systems for more.

How to best set up a mesh Wi-Fi system

A mesh system often comes in two or three hubs — referred to as a 2-pack or 3-pack.

One works as the primary router that connects to an Internet source — such as a cable modem, a Fiber-optic ONT, a gateway, or another router — using its WAN port. After that, you can add the satellite hubs to the main router.

Some mesh systems come with pre-synced hardware, such as the Asus ZenWiFi AX or Netgear Orbi. All you have to do is set up the router unit and then place the satellite at a good distance.

Most others require adding the satellite manually via a mobile app or a web interface. After that, they automatically work with the main router hub to form a unified Wi-Fi network.

Extra: Mesh and gaming

This portion of extra content is part of the explainer post on gaming routers.

Mesh Wi-Fi and Internet quality for gaming and real-time communication: Important rules

For the best online experience — including online gaming or whenever you want to make sure the connection is the most reliable and with the lowest latency — it’s always best to get your home wired.

Get your home wired (almost) like a pro, today!

After that, connect your gaming rig to your network via a network cable. No matter how fast, Wi-Fi is always less ideal and will put a few extra milliseconds, or even a lot, on your broadband’s latency.

In gaming or any real-time communication applications, reliability and low latency are actually more critical than fast speeds. So it’s more a question of wired vs Wi-Fi than Wi-Fi 5 vs Wi-Fi 6.

But we can’t use wires all the time. That said, the rule in Wi-Fi for gaming is to avoid multiple hops.

Specifically, here is the order of best practices when connecting your gaming device to the network via Wi-Fi:

  1. Use a single broadcaster — just one Wi-Fi router or access point.
  2. If you must use multiple broadcasters (like a mesh system) then:
    • Use a network cable to link them together (wired backhaul).
    • If you must use a wireless mesh then:
      • Connect the game console directly to the very first broadcaster — the primary router — of your home. Or
      • Connect the gaming device to the first mesh satellite node using a network cable. Also, in this case, it’s best to use tri-band mesh hardware.
      • Avoid the daisy-chain mesh setup.
  3. Avoid using extenders. If you must use one, make sure it’s a tri-band.

Again, the idea is that the Wi-Fi signal should not have to hop wirelessly through one extra hub before it gets to your device — you’ll get significantly worse latency after each additional hop.

The general rules of connecting mesh Wi-Fi hardware

A satellite hub must be behind the main router unit of a mesh system in terms of the network connection. Specifically, it needs to connect to the router directly or indirectly — via a switch or another satellite.

This arrangement is generally automatically the case in a wireless backhaul setup. But in a wired backhaul setup, you won’t have a mesh if you connect the satellite hub to a device in front of the router, like an existing switch or an Internet gateway.

Mesh Hardware Connection Diagram
Here’s a diagram to connect mesh hubs, applicable in situations where you have both wireless and wired backhauling. Note that many satellite hubs don’t have a WAN port and in that case, you use one of its LAN ports.

That said, here’s a simple diagram to connect a mesh system’s hardware via network cables:

Service line -> Modem or Gateway (*) -> the primary hub (router) unit of the mesh -> switch(es) / satellite unit(s) -> (switches) -> more satellites.

Wired backhaul: The only way to get the best-performing mesh

If by now you still wonder if you should use network cables to link the mesh hubs via wired Ethernet, the answer is a resounding yes.

Again, using wired backhauling via network cables is the best way to implement a mesh system. In this case, you’ll take full advantage of the mesh hardware’s network ports to deliver the best possible Wi-Fi speeds throughout.

Using wired backhauling, you don’t need to worry much about hardware arrangement. No matter the distance or placement, you’ll get the same performance from each hub. So, place the hubs in a way so that they can collectively blanket the entire desired area.

If you have Gigabit-class Internet and want to enjoy it via Wi-Fi, Multi-Gig wired backhauling is a must. Any alternative, such as Powerline (or even MoCA) won’t cut it.

In a wired backhaul setup, you can also use switches between hubs or daisy-chain the mesh hubs together — all the more flexible in hardware placement.

But running network cables can be hard or even impossible in some situations. So wireless mesh setups are popular. In this case, how you arrange the hubs is crucial.

Wireless backhaul: Super convenient but can be temperamental

Over the air, the wireless connections between the hubs can vary greatly depending on the range of the broadcasting hubs.

Extra: Wi-Fi range

This portion of extra content is part of the explainer post on Wi-Fi standards.

Wi-Fi range, in theory

The way radio waves work, a broadcaster emits signals outward as a sphere around itself — the range is the radius of this sphere.

The lower the frequency, the longer the wave can travel. AM and FM radios use frequency measured in Megahertz — you can listen to the same station in a vast area, like an entire region or a city.

Wi-Fi uses 2.4GHz, 5GHz, and 6GHz frequencies — all are incredibly high. As a result, they have much shorter ranges compared to radios. That’s not to mention a home Wi-Fi broadcaster has limited power.

But these bands have the following in common: The higher frequencies (in Hz), the higher the bandwidth (speeds), and the shorter the ranges and the more bandwidth you lose as you move farther away from the broadcaster.

Generally, within the allowed limit, physically larger Wi-Fi broadcasters tend to have more processing and broadcasting power. Still, it’s impossible to accurately determine the actual range of each because it fluctuates a great deal and depends heavily on the environment.

That said, below are my range estimates of home Wi-Fi broadcasters, via personal experiences, in the best-case scenario, i.e., open outdoor space on a sunny day.

Note: Wi-Fi ranges don’t die abruptly. They degrade gradually as you get farther away from the broadcaster. The distances mentioned below are when a client still has a signal strong enough for a meaningful connection.

  • 2.4GHz: This band has the best range, up to 200ft (61m). However, this is the most popular band, which is also used by non-Wi-Fi devices like cordless phones or TV remotes. Its real-world speeds suffer severely from interference and other things. As a result, this band now works mostly as a backup, where the range is more important than speed.
  • 5GHz: This band has much faster speeds than the 2.4GHz band but shorter ranges that max out at around 175ft (50m).
  • 6GHz: This is the latest band available, starting with Wi-Fi 6E. It has the same ceiling speed as the 5GHz band but with less interference and overheads. As a result, its actual real-world speed is faster. In return, due to the higher frequency, it has just about 70% of the range, which maxes out at about 130ft (40m).

Some might consider these numbers generous, and others will argue their router can do more, but you can use them as the base to calculate the coverage for your situation.

Wi-Fi range in real-life

Similarly-specced Wi-Fi broadcasters generally deliver the same coverage.

Specifically, if you measure the signal reach alone, they are all the same. What differentiates them is their sustained speeds and signal stability — how the quality of their Wi-Fi signals changes as you increase the distance. And that generally varies from one model to another.

In real-world usage, chances are your router’s Wi-Fi range is a lot shorter than you’d like. That’s because Wi-Fi signals are sensitive to interferences and obstacles.

The new 6GHz band generally doesn’t suffer from interference other than when you use multiple broadcasters nearby. On the other hand, the 2.4GHz and 5GHz have a long list of things that can harm their ranges.

Common 2.4 GHz interference sources
  • Other 2.4 GHz Wi-Fi broadcasters in the vicinity
  • 2.4GHz cordless phones
  • Fluorescent bulbs
  • Bluetooth radios (minimal)
  • Microwave ovens
Common 5 GHz interference sources
  • Other nearby 5GHz Wi-Fi broadcasters
  • 5GHz cordless phones
  • Radars
  • Digital satellites
Common signal blockage for all Wi-Fi bands: Walls and large objects

As for obstacles, walls are the most problematic since they are everywhere. Different types of walls block Wi-Fi signals differently, but no wall is good for Wi-Fi. Large objects, like big appliances or elevators, are bad, too.

Here are my rough estimations of how much a wall blocks Wi-Fi signals — generally use the low number for the 2.4GHz and the high one for the 5GHz, add another 10%-15% to the 5GHz’s if you use the 6GHz band:

  • A thin porous (wood, sheetrock, drywall, etc.) wall: It’ll block between 5% to 30% of Wi-Fi signals — a router’s range will be that much shorter when you place it next to the wall.
  • A thick porous wall: 20% to 40%
  • A thin nonporous (concrete, metal, ceramic tile, brick with mortar, etc.) wall: 30% to 50%
  • A thick nonporous wall: 50% to 90%.

Again, these numbers are just ballpark, but you can use them to know how far the signal will reach when you place a Wi-Fi broadcaster at a specific spot in your home. A simple rule is that more walls equal worse coverage.

When it comes to Wi-Fi coverage in a mesh system, there are two things to consider, distance and topology.

1. The distance

That’s the gap between two directly connected hubs.

The closer you keep the hubs to each other, the stronger the signals are between them, which translates into faster speeds for clients. The catch is you’ll have less Wi-Fi coverage and probably more interferences.

On the other hand, a longer distance means more extensive coverage, but you’ll end up having a slow Wi-Fi network, especially when the system has to use the slow 2.4GHz band, which has a better range than 5GHz, as backhaul.

It’s always tricky to find the sweet spot that balances coverage and speed. Generally, if there are no walls in between, you can place a hub between 40 ft (12 m) to 75 ft (23 m) from the main router unit. If there are walls, 30 ft to 40 ft is the maximum distance.

The easiest way to find out where you should put the satellite is via the signal indicator on your phone or laptop. You want to place the hub where the signals of the band you intend to use as backhaul, which is often the 5GHz, change from full bars to one or two bars lower.

Ultimately, it’s the speed that matters. If you have a modest broadband connection, you can go a bit crazy on the distance to get the most extensive coverage.

2. The topology

In a wireless setup, signal loss and latency are inevitable. The goal here is how to reduce those.

That’s where topology, which is how you arrange the hubs, comes into play. It’s relevant mostly when you can not use network cables to link the hubs.

Topology applies when you have two or more satellites. Have a 2-pack mesh? You can skip this part.

Mesh Topology
The recommended star topology (top) vs daisy-chain topology applies mostly to a mesh without wired backhauls
The star topology

This one is the recommended topology. It’s where you place the satellites around the primary router.

This arrangement ensures each satellite directly connects to the main router, making the Wi-Fi signals hop only once from the router before it gets to the end client.

The daisy-chain topology

The daisy-chain topology refers to when you linearly place the hardware units. As a result, the signal has to hop more than once — from the main router to a satellite hub, then to another satellite hub, etc.– before it gets to the device.

In this case, the net speed will suffer a great deal, and you’ll experience severe lag due to compounded signal loss. In a wireless setup, it’s always a good idea to avoid this topology.

However, if you use tri-band hardware with a dedicated backhaul, the speed will suffer significantly less than in the case of dual-band.

Mixing wired and wireless backhaul

In many cases, you can’t use wired backhauling throughout and need that extra wireless hub at the tricky spot.

In this case, keep the following in mind:

  • It’s always better to mix wired and wireless backhauls than pure wireless.
  • Only Wi-Fi clients connected to a wireless-backhaul satellite hub will suffer signal loss. Those connected to a wired hub will still enjoy fast and reliable connections.
  • It’s best to wire the router to a hub and then use another wireless hub (that connects to either.)
  • It’s OK to wire the hubs together and have (any of) them connected to the router wirelessly. However, in this case, clients connected to any satellite hub will suffer from signal loss.
  • In a mixed setup, how the dedicated wireless backhaul (available only in traditional tri-band hardware) works depends on the vendor. Some specific examples:
    • If you use Netgear hardware (Orbi, Nighthawk), the dedicated backhaul band is never available to clients. It’s wasted.
    • Linksys Velop, eero, TP-Link Deco: It’ll work dynamically.
    • Asus AiMesh or Synology mesh: It can be opened up to clients and is no longer dedicated (for the wireless satellite hub.)

How to pick the best mesh Wi-Fi system for your home

Keep in mind that you should avoid using hardware of different Wi-Fi standards on the same frequency band.

For example, Wi-Fi 6 hardware generally won’t work well with the Wi-Fi 5 counterpart in a system — the two use the same 5GHz band in different ways. In some cases, they can work but your luck will vary.

After that, there are four things you should consider when getting a Wi-Fi system: hardware units, speed, features, and privacy.

1. Number of hardware units

A home Wi-Fi broadcaster emits signals outward somewhat like a sphere. Conservatively, you can assume each hub can cover about 1500 ft2 (140 m2) — that’s multiple floors. Now consider these:

  • In a wireless setup, you can’t place the hardware units too far away from each other, as mentioned above.
  • In a wired setup, you can place them farther so their signals won’t overlap, though it’s OK if they do to a certain extent. (Use a phone or laptop to figure out the coverage of each unit as mentioned above.)

Use the numbers above to figure out how many broadcasters you will need. Generally:

  • If a single broadcaster is almost enough, then a 2-pack will do.
  • If a 2-pack of low-end hardware is barely enough, a 2-pack of a higher-end will be perfect.
  • If you’re comfortable with a low-end 3-pack, a high-end 2-pack likely won’t cut it — you’ll need a new 3-pack set of a similar higher tier.

It’s always tricky to figure out the number of necessary broadcasters. The good news is you can always start with a 2-pack and add more units later to scale up the coverage.

A tri-band Linksys Velop set is an excellent choice if you intend to mix wired and wireless backhauls with decent broadband speed.

2. Speed

Speed is, by far, the most critical factor. And this depends a lot on if your home is wired with network cables. Here are some quick bullet points:

  • Gigabit or faster: Getting your home wired is a must.
  • 300Mbps to Gigabit: Wiring is recommended, but traditional Tri-band wireless mesh will do.
  • Slower than 300Mbps: Most systems will do, though it doesn’t hurt to get your home wired.
  • For a wired home: It’s generally best to get a Dual-band Wi-Fi 6 or a Tri-band Wi-Fi 6E system. There’s no need for hardware with an additional 5GHz band.

Generally, for sharing a modest Internet connection (100Mbps download speed or slower), any mesh system, especially one using the Wi-Fi 6 standard, will do. The reason is that even slow Wi-Fi speed is still much faster than the broadband speed.

However, if you pay for a fast Internet plan — 300 Mbps or higher — you’ll need a system that has a dedicated backhaul band or a top-tier dual-band system.

Netgear Orbi RBKE960 Quad-band Mesh Wi-Fi 6E System
The Netgear Orbi RBKE960 series is the first Quad-band mesh system ideal for a wireless or mixed environment with sub-Gigabit bandwidth demand.

And if you have an ultra-high-speed internet connection (500 Mbps or faster), you’ll need to run network cables to connect the hubs. There’s no way around this.

Even when you use a tri-band Wi-Fi 6 mesh system, you won’t get full Gigabit at the end device unless you use wired backhauls.

Best Wi-Fi 6 Mesh Systems: You Will Find the Right One Among These!

Again, with a wired backhaul, all you need is a Dual-band system with top Wi-Fi speed. But if you want to get the last, pick one among these Wi-Fi 6E systems.

For example, the Asus ZenWiFi AX Mini or TP-Link Deco X60 will deliver excellent sub-Gigabit Wi-Fi rates in a wired setup. If you have Gigabit Internet, a couple of Asus RT-AX8xU units or most dual-band Wi-Fi 6 systems will do.

If you intend to mix both wired and wireless backhaul, it’s good to use a system that supports both well, such as a Tri-band AiMesh or Linksys Velop set.

And finally, if you’re looking into Gig+ broadband, that’s Internet speed faster than Gigabit, you have to get your home wired and use a system that can handle Multi-Gig wired backhaul.

3. Features

The feature set of a system means what you can do with your home network.

If all you want is to access the Internet, don’t worry about features. However, it’s always helpful to have a system that includes lots of customization and built-in online protection.

I’m not a fan of mesh systems (or routers) without a web interface since they don’t offer users full network control.

If you want tons of useful features and network settings, use a mesh system from Asus or Synology. The runners-up are those from TP-Link, Netgear, or Linksys. Others tend to have a limited amount of features and network settings. In return, they are much easier to set up.

4. Privacy

All Wi-Fi systems requiring you to register a login account for setup and ongoing management can cause privacy risks.

Your router and privacy risks: It’s about the (lack of) awareness

Your network connects to the vendor at all times, and potentially, third parties can keep tabs on what you do online. What happens behind the scenes is generally unknown, and some vendors are worse than others on this front.

Extreme examples of this type of what I’d call “data-mining mesh systems” are those from Google and Amazon. I’d recommend against them even though they might offer reliable performance and ease of use.

Final note

The primary hub of your mesh system should be the only router of your home network.

If you already have an existing router, such as the case where you can’t remove the ISP-provided gateway, get a mesh that can work in the access point (AP) mode. In this case, the mesh extends your existing home network without offering any features or special settings.

Or you can also turn the existing gateway into a modem by putting it into bridge mode.

Double NAT vs Single NAT: How to best use the ISP-provided gateway

No matter what setup you decide to go for, two things are always true:

  • Using network cables to link the hardware units is the only way to get the best-performing system.
  • Wi-Fi is always a matter of nuance:
    • It never works like when you connect your computer via a network cable.
    • The performance is always worse than what the vendor claims.

That said, get your home wired, take what the vendor says with a great grain of salt, and most importantly, read the individual reviews of these systems with some attention.

The information with what you want, need, and your home’s layout. You’ll be able to figure out what fits you best.
