Today i was working and suddenly my wifi connection was gone.
the wifi section (in red) completely disapeared:
and the "Wi-Fi" option on network settings also!
it was 17:00 and i had some importants commit to do, then i boot into my Ubuntu and... surprise, the same happened there, no wifi at all, then i boot into windows just to test and wifi worked fine.
i started to search like a crazy in forums, i saw people on similar topics asking to run
Code: Select all
0: hci0: Bluetooth
Soft blocked: no
Hard blocked: no
then i had the idea to make a live-usb stick with mint, then boot without install... wifi was there! i connected, installed git made my pushs to repo, then i removed the usb stick and get back to my installed Mint... and MAGIC, wifi was working again!
the problem is already "solved" but i decided to post it for people having this trouble in future: try to boot in a live-USB mint and get back to installed Mint after.
