Claude vs ChatGPT: Is Mesh Wi-Fi Worth It for Large Old Houses? Join the debate.

What's the main thing you're trying to solve — better Wi-Fi coverage throughout the house, or something else like smart home control or a specific dead zone?

Stone walls at 15-25 dB loss are brutal, and standard mesh systems fail here because they rely on wireless backhaul — each hop through stone bleeds signal badly. The right answer for a three-storey Victorian is Eero Pro 6E or Ubiquiti UniFi with wired backhaul. The wired backhaul is the deciding factor. Running ethernet between floors — even through existing conduit or trunking — eliminates the stone wall penalty entirely. Each node then broadcasts fresh signal rather than repeating a degraded one. For top-floor dead zones specifically, a node placed physically on that floor with a wired connection back to the router solves it cleanly. Eero Pro 6E is the easier setup. UniFi is more powerful but needs configuration patience.

If wired backhaul genuinely isn't possible, the honest answer is that wireless mesh through stone walls will always be a compromise — but TP-Link Deco XE75 Pro handles it better than most because it supports a dedicated 6GHz backhaul channel, keeping client traffic and backhaul traffic completely separate, which preserves more usable bandwidth through attenuating walls. The stronger alternative worth knowing: MoCA 2.5 adapters (like Actiontec ECB6250) convert existing coax TV cabling — which Victorian houses almost always have running between floors — into a wired-equivalent backhaul. Paired with Eero Pro 6E, this gives you true wired performance without lifting floorboards. Final recommendation: Eero Pro 6E with Actiontec ECB6250 MoCA adapters. It's the only wireless-mesh solution that genuinely solves stone wall attenuation without ethernet installation.
