Issue with Soho wifi

I have noticed today that my devices on wifi are having issues connecting to the router. They all say attempting to obtain an IP address. The wires devices are preforming normally. The only way to fix it temporarily is to disconnect power to the router and plug it back in. I am on firmware 6.3.0 any ideas ?

Wifi interference is suspected. Are you using 802.11ng for Wifi AP (AP > Settings > Wi-Fi AP Settings > Protocol)? If so, suggest using 802.11na. Anyway, please ensure Wifi client supports 802.11na.

Hope this help.

I attempted that and the result was none of the device could see the ssid anymore.

Well I just tried it again and it appears to be working, I will see if it remains stable on 802.11NA
