Wifi router disconnects and reconnects when on 5ghz band
TP LINK Archer C80
Firmware : 1.12.0 Build 220924 Rel.63783n(5553)
Hardware : Archer C80 2.20
Problem : Whenever on the 5ghz band, the router disconnects and reconnects. This happens whenever the 5ghz band is enabled or smart connect is enabled. This issue never happens when only 2.4 ghz band is enabled.
I have tried changing band frequency, width etc but the issue still exists. There are no issues from the ISP end. My firmware is updated to the latest version.
I have got the router recently and updated it to the latest version when I was setting it up so I dont know if this issue is because of the the firmware update.
There is a similar issue someone was facing with the same router, he was provided with a beta firmware update file and that seems to have fixed the issue for them but my router verison is V2 and the one mentioned in that theread was V1,so that file dosent work for me.

Please anybody help !!!
PS: at anytime only 2-3 devices are connected to the router and the router is placed properly.
