Devices do not connect after router restarted

[santhoshak]

Hi,

I bought CAX30 Cable Modem Router from Costco in July 2021. In last couple of months, whenever I restart my router, all of my devices disconnect from router except couple of them. Only way to get the router back to working is to reset, give new name to the SSID and connect all the devices once again. I have multiple smart switches, smart plug which needs to be re-connected everytime this happens.

Since my router is out of warranty, Netgear support cannot help unfortunately. Did anyone face similar issues?

What Firmware version is currently loaded?

How is the Basic Tab/Wireless settings and Advanced Tab/Advanced wireless settings configured? 

What channels are you using? Auto? Try setting manual channel 1, 6 or 11 on 2.4Ghz and 40 to 48 channel on 5Ghz.
Any Wifi Neighbors near by? If so, how many?
