TP-Link Deco XE75 Pro: A Multi-Gig Mesh Tease

TP-Link Deco XE75 Pro: A Multi-Gig Mesh Tease

Posted on


TP-Link today announced the availability of the Deco XE75 Pro AXE5400 Wi-Fi 6E Tri-Band Mesh system.

Let’s call it the Deco XE75 Pro going forward.

You will likely hear a lot of cheap superlatives about this new mesh — “lighting fast” is among sure bets — but here’s the real deal: It’s the Deco XE75 with a 2.5Gbps Multi-Gig (WAN/LAN) port.

As I briefly mentioned in the review of the Deco X4300 Pro, there will be more “Pro” hardware coming from the networking vendor, and they all have one thing in common: The support for Multi-Gig.

And here’s the bottom line: Much that TP-Link tries so hard to create a “wow” effect, there’s nothing earth-shattering about the Deco XE75 Pro. It’s not even noteworthy, making the $100 extra cost over the previous version poorly justified.

The 2.5Gbps is the only thing that differentiates the new TP-Link Deco XE75 Pro from the Deco XE75. Don’t take the “Lighting-Fast” notion too seriously!

TP-Link Deco XE75: The same mesh with a single Multi-Gig port

The headline above says it all. The Deco XE75 Pro is the same as the Deco XE75 plus a 2.5Gbps port that can work either as a WAN (to host a fast internet connection) or a LAN (for a fast local device.)

“Or” is the keyword here since you can’t have both. For that, you’d need two or more Multi-Gig ports.

While there will be TP-Link hardware with multiple Multi-Gig ports, a single-port approach will be prevalent. That’s the case for all hardware vendors. If you don’t believe me, here’s the list of almost all other existing Multi-Gig home Wi-Fi broadcasters.

Like any wired standards, you need the same speed grade on both the in and out ends to truly experience it. With just a single port, this type of hardware is close to a Multi-Gig nothing burger. They are better than pure Gigabit hardware, but in real-world usage, they make almost no difference.

With that, let’s check out the Deco XE75 Pro’s hardware specifications.

Deco XE75 Pro vs Deco XE75: Hardware specifications

The two are identical with one exception, the Deco XE75 Pro has one 2.5Gbps port and costs $100 more. There’s almost no situation where you’ll see the benefit of that extra cost.

Deco XE75 Pro: That all-brag little-substance Multi-Gig approach

The Deco XE75 Pro feels awfully similar to other cheap Multi-Gi approaches.

The vendor will pick and choose to prop up the hardware. But it makes no sense if you pay attention. There’s not much you can achieve with a single 2.5Gbps port.

Specifically, with that single low-grade Multi-Gig port, the Deco XE75 Pro can:

  • Host a 2.5Gbps broadband connection. Or
  • Host a 2.5Gbps local link, such as a server.

In either case, the best you can experience is still:

  • Gigabit via one of its other 1Gbps LAN ports.
  • Gig+ via Wi-Fi. (The Deco XE75 Pro’s Wi-Fi caps at 2402Mbps of theoretical speed, which translate into Gig+ in real-world sustained speed, at best.)

What is Gig+

Gig+, or Gig plus, conveys a speed grade faster than 1Gbps but slower than 2Gbps. So, it’s 1.5Gbps, give or take, and it’s not fast enough to be qualified as Multi-Gig.

Gig+ generally applies to the sustained speeds of Wi-Fi 6 or 6E (via a 2×2 connection) or Internet speed, not wired local connections.

The point is, in most cases, you’ll see no difference on a single client where the router will likely cap at Gigabit anyway, just like the case of the Deco XE75 (the non-Pro version.)

In short, there’s no way to get a real Multi-Gig connection out of the Deco XE75 Pro, just like the case of the Deco XE75. And all that makes the new former somewhat of a ripoff.

Deco XE75 Pro: It’s the Deco XE75 at heart

The takeaway is this: other than the 2.5Gbps port, the Deco XE75 Pro is literally the same as the Deco XE75.

The two share the same firmware, Wi-Fi settings, network configurations, and features. You must use the Deco mobile app for the setup process and ongoing management. So on and so forth. You can find out more in my review of the Deco XE75.

Like all Deco sets, the new Deco XE75 Pro has little to offer in features and settings by default. If you want more, you’ll have to pay for HomeShield Pro, which requires a subscription. But even then, the mesh still has much less to offer than TP-Link’s Archer routers.

Pricing and availability

The Deco XE75 Pro AXE5400 Tri-Band Mesh Wi-Fi 6E system is available now as a 2-pack or 3-pack with the suggested retail price of $399.99 or $599.99.

Considering the fact that the Deco XE75 proved an excellent system in my testing, it’s safe to say the Deco XE75 Pro will likely pan out the same. So the only question is if the 2.5Gbps port is worth the extra cost. And that’s your call.
