ZenWiFi BT6

Most likely no need for mesh - I'd get any single ASUS WIFI 6e or 7 router in the $150-$250 range (bt6,bt8,be92u,be86u, etc etc)Run the ATT unit in passthrough and the more powerful router should cover the 1100 sqft - as other have said you could run a cat6 cable from the ATTunit to a more central s

i have the telus internet service with the boost. I also had my own mesh so I could reach far away spots in my 3 storey house and the backyard.

I would stick with Asus. I went from (2) rtac86u routers to (2) ZenWifi BT6 (Wifi7) routers. I've had them for about 3-Months now with zero issues. Of course going from Wifi5 to Wifi7 has improved performance pretty substantially. Last time I checked, Asus was Taiwanese owned.

I’ve used a number of asus routers in wireless and wired back haul modes over the years and they’ve been quite good. Currently using 2 bt6 in wired back haul to provide coverage to a 3500 sq ft house over 3 levels. Cheers
