TP-Link Deco BE9300 WiFi 7 Mesh System Review UK (2026) - Tested

Look, I've been testing mesh systems for over a decade now, and the jump to WiFi 7 has been... well, let's just say not every system justifies the premium price tag. So when I got my hands on the TP-Link Deco BE9300, I wanted to see if those 9335 Mbps claims actually translate to real-world performance. After three weeks of pushing this system through a typical UK semi-detached house with thick walls and multiple devices, I've got some definitive answers about whether this lives up to the hype or if you're better off saving your money.

The MLO (Multi-Link Operation) feature deserves special mention. It's WiFi 7's killer feature, letting compatible devices use multiple bands at once. Problem is, you need WiFi 7 client devices. And in February 2026, those are still pretty rare outside flagship phones and laptops. So you're buying into future performance here.

What I really appreciated was the hybrid backhaul. I've got ethernet running to one satellite unit (the bedroom), and the system intelligently uses both the wired connection and wireless mesh simultaneously. It's clever stuff that actually improves performance rather than just being a marketing tick-box.

Testing conducted with WiFi 7 laptop (Intel BE200), WiFi 6E phone (Samsung S24 Ultra), and various WiFi 6 devices. Broadband: Virgin Media 1Gig. Two-unit setup covering 140sqm.

What impressed me most wasn't the peak speeds (though they're brilliant). It's the consistency. I ran continuous ping tests whilst streaming 4K content, and latency stayed rock-solid at 4-6ms to the router. Gaming on WiFi actually felt responsive, which is saying something.

The 2.4GHz band handles IoT duties perfectly - I've got 23 smart home devices connected, and they're all stable. The system's smart enough to keep them on 2.4GHz whilst pushing performance devices to 5GHz or 6GHz.

Each unit measures about 110mm diameter and 110mm tall - not exactly discrete, but not offensive either. They need to sit in the open for best performance (don't stick them in a cupboard), and the white finish works in most homes.

Heat management is spot-on. After three weeks of continuous operation with heavy load testing, the units stay barely warm to touch. There's clearly decent thermal engineering inside, which bodes well for longevity.

The ethernet ports are on the bottom, which is slightly annoying for cable management but keeps things tidy. All four ports are 2.5GbE with auto-sensing WAN/LAN configuration - the system figures out which one's connected to your modem automatically.

Here's where TP-Link gets it right: the app doesn't overwhelm you with settings. Basic users get a simple interface with the essentials. But tap into advanced settings, and you'll find proper control over band steering, backhaul preferences, QoS rules, and port forwarding. It strikes a good balance.

One feature I actually use is the device prioritisation. You can set specific devices (like a work laptop) to get bandwidth priority during certain hours. When you're away from home on public WiFi, pairing this with a good VPN adds an extra security layer on top of the network this system creates. It's not just marketing fluff - I noticed fewer Teams call drops during peak evening usage after enabling it.

The Netgear Orbi 970 is faster and includes a 10 Gigabit port, but you're paying nearly £200 more for features most people won't use yet. Unless you've got 2.5Gig+ broadband, it's overkill.

The ASUS ZenWiFi BQ16 is closer in price but only has two 2.5GbE ports per unit. If you're planning to wire multiple devices per node, that's limiting. The BE9300's four ports per unit gives you proper flexibility.

Against WiFi 6E alternatives like the Deco X50 or X60? You're paying roughly double. The performance gap is noticeable if you've got WiFi 7 devices, but if your newest device is WiFi 6, save your money and get the X60 instead.

The complaints are pretty minor, honestly. Most negative reviews come from people who bought this for standard broadband and WiFi 6 devices - they're not seeing the benefit because they can't utilise the performance. If you're in that boat, seriously consider whether you need WiFi 7 right now.

Here's my honest take on value: if you're running gigabit+ broadband (500Mbps minimum to see real benefit) and have at least a couple of WiFi 6E or WiFi 7 devices, this makes sense. The four 2.5GbE ports alone add significant value - you'd pay £437.99+ for a decent 2.5Gig switch.

But if you're on standard 100-300Mbps broadband with mostly WiFi 5 and WiFi 6 devices? You're wasting money. The Deco X50 will serve you just as well at less than half the cost.
