I am trying to connect to wifi in ubuntu then suddenly the wifi adapter stops (ubuntu setting shows no wifi option). When I checked system logs using journalctl -ef I get the following output:

This error has been happening for sometime now and mostly fixes by a reboot. But currently the frequency of this error gets increasing day by day. I am sharing some other info related to hardware:

Please help me diagnose the error, and how to fix it. The wifi had worked properly for a some months before this error had occured.If I use a spare USB wifi adapter from my home, the wifi runs properly.
