Wifi available but not working

Hi, @testingcont,
Your wifi is down, although is present.
You can check whether is blocked or not with the following terminal command:
sudo rfkill list all.

I also suggest you to look at this couple of post, in order to try to solve your problem.
Wireless Connection randomly disconnects, restart is required - #12 by TriMoon

Wifi shows its connected for 5Ghz radio but will not resolve an address, but connecting with 2.4Ghz Radio always works - #2 by megavolt

Hope it help, regards
