AX92u Mesh and rDevices roaming

[Esieens]

Hello – I have a weird issue.

I have two ax92u used in as tri-band AP in a mesh network with Ethernet backhaul: one downstairs (the master), one upstairs (1st floor).

I only see a few devices connecting to the upstairs ax92u (mainly on 5.2ghz and 2.4ghz WiFi networks). I have an iPad Air 5, on the 2nd floor, which can only connect to the upstairs one on 2.4ghz, and only if I bind the device to the upstairs ax92u only.

I have tried to change the roaming settings and it made no difference. I did one more test: I set a Mac filter to reject 2.4ghz connection for that device and bound it to the upstairs ax92u: the device could not connect to the WiFi anymore. It’s like the upstairs ax92u is rejecting a 5.2ghz connection for my iPad.

Any idea what could be wrong? Thx

Likely you have messed too much with the WIFI settings. Recommend factory reset for both devices, use the Smart Connect, use WPA2-Personal only, leave the WIFI channel at Auto and leave the AiMesh settings at default. You may want to disable DFS channels. Since you have Ethernet backhaul, once the system is stable you should be able to enable the AiMesh Ethernet Backhaul but it is really not necessary. Setting the 2.4 GHz to 20 MHz and the 5 GHz to 80 MHz will give more stable connections/performance.

All your other devices are behaving the same? Or it's only that iPad that's doing the same?
Do you have separate SSIDs for 5 and 2GHz? Or you're using Smart Connect and use the same SSID on all radios across both routers?
Anyways, I agree with @bbunge, if you ended up playing with roaming settings and mac filtering you went one step too many and starting fresh is the best next thing.
Usually modern Apple devices are playing good enough. What you're describing may be a sticky device and that would be common with really cheap devices. Somehow...did you buy that ipad from a legit source? Or it's a black import?
I would forget the connection on that ipad and try again. Especially if you have other devices that are behaving as you expect.
But if you changed many settings on the routers, it would be best to factory reset and start fresh.
