I've seen people having the same problem as me, although when they went to the Network parameters they were able to disable airplane mode and/or turn on the wireless setting, but I am not... When I try to turn it on, even though airplane mode is deactivated (which it enables right after I close the parameters window) it just turns back off right after. I tried
rfkill unblock all or
sudo rfkill unblock wifi but when it asks me for my password it just doesn't do anything and I'm really wondering why. I tried to restart my laptop, but it didn't help.
Maybe it's just a bug, and I have to wait for the newer version but what can I do if I can't download it from the Internet?
