Wifi not working

[jtreg]

Hi

I installed Armbian and happily browsing internet. Suddenly the screen went black. I could not bring back any screen so I rebooted (pulled plug!) - The machine is back but now I cant connect to internet. I can connect to wifi not internet. I will try Ethernet tomorrow when I am home. Any idea how to test/fix?
cheers

Maybe something in filesystem, related to wi-fi, was corrupted - you may check with new system image.

Also, Armbian use a slightly higher CPU frequency settings (2.0GHz for A72 cores instead 1.8) - and required more power (and cooling system too) - so it can be good idea to try to use another/more powerful power supply.
