  • Welcome! You'll need to provide some info about the wireless hardware. For example, open a terminal window, type lspci -nnk | grep -A3 0280, and hit Enter. Then edit the question, and add the output to it.

Please try this workaround (not a fix):

After you boot the system, suspend and wake up. Now check if wifi networks are detected or not. I read this somewhere sometime ago, it works for my hp laptop.
