as the title suggests, by WIFI keeps getting hard blocked randomly. This happens in middle of some video stream or even if it is idle.

I have tried disabling automatic suspend in Settings > Power as suggested in Ubuntu 20.04 wifi randomly disconnecting but to no help.

I have a RaLink RT3090 1T/1R internal WIFI adapter and a RealTek RTL8188EUS USB adapter. Both are disabled when this happens.

Below are the list of commands which @heynnema suggested in one of the comments.

I am happy to provide any other outputs as needed, please help me solve this issue.

Except for rfkill list all all other commands were executed when WIFI was not hard blocked.

rfkill list all

Try

rfkill unblock all

Otherwise there could be combination of control plus a function key to unblock your adapter.

    Thank you for the answer, unfortunately this does not help. I have a combination of keys to unblock, but it keep on disconnecting very frequently and have to do it regularly. – prinkpan Feb 14 '21 at 15:52
