I have 2 routers in my setup. The second one is an asus slaved to the primary one, the latter connected to the internet. The asus models allow for fairly advanced configuration, you just need to disable dhcp and set it to bridge mode and it then acts as a wap. I suspect that this is the configuration that Nick has enabled. I was considering a dual asus setup to use the aimesh capability but as Nick has had issues with it I think I’ll stick with what I have. It’s easy to end up with multiple routers if you switch provider, I now have a bt home hub, the freebie router from EE, an asus which I bought, and a fritz box provided by zen (our current broadband provider). I couldn’t get the home hub to work as an access point slaved from the fritz box but the asus appears to work. The downside is 2 separate ssid’s so I’m considering the whole home WiFi solution from bt, one to slave from the Fritz box and a second to replace the asus. If I set the asus and Fritz ssid’s to be the same, a wandering device doesn’t appear to auto switch to the nearest / best signal access point, which I believe a mesh system solves.
