TP-Link Deco vs Eero vs Asus ZenWiFi: Wi-Fi 7 Mesh (2026)

All three of these flagship Wi-Fi 7 mesh systems will saturate a UK fibre line and cover a 3-bed semi without breaking a sweat. The choice between TP-Link Deco BE85, Amazon Eero Max 7, and Asus ZenWiFi BT10 isn't really about speed - it's about which smart-home ecosystem you've already bought into, how much you want to tinker, and whether you'd rather pay a one-off premium or rent the security features back as a subscription.

On paper, all three are tri-band Wi-Fi 7 mesh systems with two 10GbE ports per node, Multi-Link Operation (MLO), and 320 MHz channels on the 6 GHz band. In a blind speed test against a 1 Gbps or 2 Gbps line, you'd struggle to tell them apart - every one of them will deliver the full line speed to a Wi-Fi 7 client in the same room. The differences sit in everything around the radios.

The Deco BE85 wins the spec war. Its BE22000 class rating is the highest of the three, and it has the most flexible port layout (two 10GbE plus two 2.5GbE on every node). If your priorities are wired backhaul to a 10GbE NAS and the absolute headroom for a Wi-Fi 7 client laptop, that's the one.

The Eero Max 7 trades raw spec for ecosystem integration. Every node is also a Thread border router and a Zigbee 3.0 controller, which means a single Eero pack can act as the Matter/Thread fabric anchor for a smart home - you don't need a separate Apple TV, Echo Hub, or Aqara hub for the Thread side. If you're already using Echo speakers, the management cohesion is hard to beat. The trade-off is that Eero's firmware is the most closed of the three - no VLANs, no custom DNS at the router level, and the more useful security features sit behind Eero Plus.

The Asus BT10 is the enthusiast pick. It runs full ASUSWRT, the same firmware as Asus's high-end ROG routers, which means proper VLANs, OpenVPN and WireGuard servers, custom DNS, per-device QoS, and a traffic analyser that actually shows you which devices are eating bandwidth. AiProtection Pro (powered by Trend Micro) is included free for the lifetime of the device - no subscription. The catch is the app and web UI: both are functional but cluttered, and first-time mesh users will find Eero or Deco friendlier.

This is where Eero pulls ahead by a clear margin. Eero Max 7 nodes are the only ones of the three with native Zigbee 3.0 and Thread border router radios baked in. For a Matter smart home, that's significant - Thread devices need a border router on the network to reach the Matter fabric, and most households end up adding an Apple TV, Echo Hub, or Aqara hub specifically to provide one. With Eero Max 7, every node already does it.

The Deco BE85 and Asus BT10 are both Wi-Fi-only - no Zigbee, no Thread. You'll still need a separate hub for the Matter side. For most households, that hub is already there in the form of an Apple TV 4K, an Echo Hub, or a SmartThings Station, so this isn't a deal-breaker. But if you're starting from scratch on a Matter house, the Eero saves you a £100 hub purchase and one fewer plug to find.

For voice control, all three play nicely with all three big assistants - there's no router on the market today that locks you out of Google Home or Alexa. Eero has the smoothest Alexa integration (it's the same company), and Asus has historically had the deepest Google Home integration on the router-OS side. Deco sits in the middle.

The headline UK prices look very different - Eero Max 7 starts at around £550 for a single node, Asus BT10 at around £700, and the Deco BE85 around £650 for a single unit or £999 for the two-pack. But the headline price isn't the whole cost.

Eero's free tier covers basic firewalling and parental schedules. Anything more - ad-blocking, VPN, threat scanning, advanced parental controls - sits behind Eero Plus at roughly £99/year. Over a five-year ownership window, that's another £500 on top of the hardware.

TP-Link offers a similar split. HomeShield's free tier is acceptable, but HomeShield Pro (around £55/year) is needed for the more useful filtering and reporting features.

Asus is the outlier here. AiProtection Pro - Trend Micro's gateway security suite - is included free for the device's lifetime. No subscription, no upsell. If you'd otherwise pay for one of the other two's premium tier, the Asus's £100-£150 hardware premium amortises within two years.

All three perform substantially better with wired backhaul than wireless, and all three support it via their 10GbE ports. The differences are at the edges.

Deco BE85 has the most flexible port layout - four multi-gig ports per node (two 10GbE plus two 2.5GbE). That means each node can act as a small switch for nearby devices (NAS, gaming PC, TV box) without needing an extra switch. If you have a 10GbE NAS, the Deco is the natural pick.

Asus BT10 has two 10GbE ports plus three 2.5GbE - slightly less generous on the 10GbE side but more wired ports overall. Eero Max 7 also has two 10GbE plus two 2.5GbE, similar to the Deco but without the Deco's flexible role-assignment (the Eero's WAN port is more rigidly assigned).

For most UK households on a 1 Gbps or sub-1 Gbps fibre line, this distinction is academic - you're not pushing anywhere near 10 Gbps over the local network. But if you're planning a 10GbE switch and NAS upgrade, the Deco BE85's port count makes it the slightly more future-proof pick.

All three are tri-band, which means the third band (6 GHz) can be dedicated to wireless backhaul between nodes - leaving the 5 GHz band fully available for client traffic. That's the headline reason any of them outperforms a typical dual-band mesh.

Real-world coverage per node in a dense smart-home environment (lots of devices, plenty of walls) lands around 120-200 m² for all three. Manufacturer claims of 230-280 m² per node are optimistic - they assume an open warehouse, not a brick-walled UK terrace. A two-pack covers a 3-bed semi or terrace comfortably. A three-pack handles a 4-bed semi or a small detached. Add a node every 9-12 metres of solid signal - past that point, the third band has to start working hard and you'll see the wireless backhaul cap your client throughput.

If you're in a flat or a small 2-bed terrace, you almost certainly don't need three nodes - a single Deco BE85 or a two-pack of any of these is plenty.

Pick the TP-Link Deco BE85 if your priorities are raw throughput, multi-gig ports for wired backhaul, and you don't want a subscription unless you absolutely need one. It's the pick for someone planning a 10GbE network upgrade and who already has a separate Matter hub.

Pick the Amazon Eero Max 7 if you already live in the Amazon ecosystem (Echo, Ring, Blink, Fire TV), or if you want a router that doubles as your Matter/Thread fabric anchor. The setup is the easiest of the three, and the Thread border router on every node is a real differentiator. Be ready to budget for Eero Plus if you want the security features.

Pick the Asus ZenWiFi BT10 if you want proper network controls (VLANs, WireGuard, custom DNS) without dropping into prosumer kit like Unifi. The free-for-life AiProtection Pro is genuinely useful, and AiMesh's backwards compatibility with older Asus routers makes it the kindest pick for anyone upgrading from a previous Asus router.
