That is not a WiFi radio issue because you are still connected to it; just no internet.

Please connect to your OpenWrt device using ssh and copy the output of the following commands and post it here using the "Preformatted text </> " button:

I meant it is not a radio issue.

While others look at the dump, snip the Network & Internet-> Ethernet (known good)
and
Network & Internet-> Wireless
DHCP settings and see if anything changes next time the WiFi looses internet.

Do not associate more than one network with an SSID. The lan network is currently selected and that is correct.

What is the output of

I'm not seeing the issue. Hopefully someone else will spot it.

The issue will be no Internet or connection to OpenWRT page on WIFI of the board but any device connecting on ethernet can get access

Sorry.. what I meant was that I understand that you are having that issue, but I don't see anything wrong in the configs and hopefully someone else will see what I'm missing.

I meant to look for IP, gateway and dns changes in Windows; I should have made that clear.

Next time you lose connection, see how Windows handles it.

Dear

Checking Windows only for changes is fine.

To be clear:
Note the DHCP settings while working and then look for any changes when the internet drops.
