The first thing this house taught me, long before any of the clever stuff, is that it does not want me to have Wi-Fi in the back rooms. And it is prepared to die on that hill, because the hill is two leaves of fired clay with a cavity in the middle, and it was here a hundred years before me and it will be here long after the last of my gadgets is landfill.

Double brick. Beautiful. Solid. Genuinely cool in an Adelaide February. And to a 5GHz signal, roughly as transparent as a bank vault.

The wall, doing its job a little too well

I tried to fix it the way the box tells you to. I had ASUS gear running AiMesh, and the back of the house was a dead zone, so I bought a couple of Google Nest WiFi nodes because they were on special, and I am, at my core, a man who buys things on special. Here is what I learned for my money: Nest nodes will not join an AiMesh network. Not "with some fiddling." Not at all. Different mesh ecosystems do not combine. They just sit in the same house ignoring each other, two relay teams who refuse to pass the baton, while you stand in the hallway watching a video buffer.

That’s the part nobody selling you mesh wants to say out loud. Mesh is not a magic cloud of signal. It’s a relay race, and every leg of the race still has to get through the wall. A node on the wrong side of double brick isn’t extending your network; it’s just a glowing ornament reporting a strong connection to nothing.

The fix is boring and it involves a drill.

Run wired backhaul wherever you physically can — even one Ethernet cable to a single back-room access point does more than three wireless nodes praying through the brick. Stay inside one ecosystem (more ASUS AiMesh hardware, not a Nest mongrel). And accept the thing that took me longest to accept: the router lives where the signal needs to go, not where it looks tidiest in the study. Function, then feng shui.

The Nest nodes are in a drawer now. They make a good paperweight. They cannot, sadly, mesh with the drawer.

THE LEDGER

Cost: ~$300 in nodes that don’t talk to my network

Actual cost: a fortnight of believing the problem was a setting

Survives a firmware update? The wall does. Everything else is negotiable.

Verdict: One wired access point beats three hopeful wireless ones. Buy the cable.
