TP-Link Deco BE65 Mesh WiFi 7 System Review UK 2026

Look, I’ve tested enough mesh systems to know that the numbers on the box rarely tell the full story. WiFi 7 promises the world, but does it actually deliver in a typical UK home with brick walls and interference from every neighbour’s router? I spent three weeks with the TP-Link Deco BE65 to find out what really matters: consistent coverage, actual speeds, and whether that premium price tag makes any sense.

The tri-band setup is clever. Most mesh systems use one band for backhaul (communication between nodes), which eats into your usable bandwidth. The BE65 dedicates the 6GHz band primarily for backhaul whilst still serving 6GHz-capable devices. It’s a proper implementation that actually matters for performance.

Multi-Link Operation is the real WiFi 7 party trick. When I tested with a WiFi 7 laptop, the system bonded the 5GHz and 6GHz bands simultaneously, delivering combined throughput that WiFi 6E simply can’t match. But here’s the catch: you need WiFi 7 client devices to benefit, and those are still rare in early 2026. Most of your kit is probably WiFi 6 or older.

Right, let’s talk about what these numbers actually mean. That 2.1Gbps close-range speed? That’s genuinely impressive and represents real-world throughput I could sustain during large file transfers. Most mesh systems claim big numbers but deliver half that in practice. The BE65 gets closer to its theoretical maximum than any system I’ve tested.

But here’s where it gets interesting (and a bit frustrating). With my WiFi 6 devices – which is most of my kit – speeds topped out around 850Mbps on the 5GHz band. That’s still excellent, but you’re not seeing the full benefit of WiFi 7 hardware. The system is future-proofed, which is great if you’re planning to keep it for 5+ years. Less great if you want immediate value.

The latency performance genuinely surprised me. Gaming on WiFi has always meant accepting a penalty, but the BE65’s 3-5ms local latency is close enough to wired that I couldn’t feel the difference in fast-paced shooters. That’s down to WiFi 7’s improved efficiency and the dedicated 6GHz band reducing interference.

Build quality is proper but not exceptional. The plastic feels solid enough, and there’s adequate ventilation to keep thermals under control. After three weeks of continuous operation, the units run warm but never concerning. I measured surface temperatures around 38-42°C under load, which is perfectly acceptable.

My main gripe? At this price point, I’d expect metal construction or at least a more premium finish. The glossy LED ring looks a bit naff and attracts fingerprints. You can disable the LED in the app, which I did immediately because the pulsing light is distracting in a bedroom.

The app itself is a mixed bag. For basic users, it’s brilliant – simple interface, clear status indicators, easy guest network creation. But if you’re a networking enthusiast who wants granular control, you’ll find it frustrating. There’s no web interface, no SSH access, and limited manual band steering options. You’re trusting TP-Link’s automation, which works well but removes control.

One feature I appreciate: network optimisation runs automatically. The system analyses channel congestion and adjusts settings overnight. I never had to manually optimise channels or adjust transmit power. It just works, which is exactly what most buyers want from a mesh system.

Against the ASUS ZenWiFi BQ16, the BE65 trades blows. ASUS offers better app control and slightly higher theoretical speeds, but costs about 20% more. In my testing, real-world performance was nearly identical between the two. The choice comes down to whether you value TP-Link’s simplicity or ASUS’s advanced features.

Here’s my take: the BE65 offers about 80% of flagship performance at 50-60% of the cost. For most users, that’s the sweet spot. You’re getting genuine WiFi 7 capability without paying the early adopter tax that Netgear and ASUS command. But if you need 10Gbps wired connectivity or maximum coverage, look at the pricier options.

Value is the tricky question with WiFi 7 in early 2026. The technology is brilliant, but most people’s devices can’t take full advantage yet. If you’re running WiFi 6 clients on a 500Mbps connection, you’re paying for capability you won’t use for years.

But. If you’ve got gigabit+ broadband, you’re planning to upgrade devices over the next few years, and you want a system that’ll last through 2030 without feeling outdated, the BE65 makes sense. The performance is there, the reliability is proven, and the price is reasonable for what you’re getting in the WiFi 7 space.

Compare it to WiFi 6E alternatives around £350-400. You’d save about £150-200 and get 70-80% of the performance with current devices. That’s the sensible choice for most buyers right now. The BE65 is for early adopters and enthusiasts who value having the latest technology and maximum future-proofing.
