Hello community,

I've had the Archer AX73 (AX5400) for a few years now and haven't faced any trouble until a few days ago where the WiFi stopped working on some devices. I've tried everything from firmware update to factory reset. 

Yesterday, after factory reset and rebooting the router, the WiFi started working on all devices again but this morning the same issue has occurred. As of now, the Wi-Fi is working on my iPad but isn't working on other devices like the OnePlus 8 Pro, Samsung phones etc. 

Surprisingly, my TP Link Wi-Fi extender (TP-WA850RE) which is connected AX73's WiFi is working and that's what my devices are connected to.

Please suggest a fix 

Thank you
