I've installed Ubuntu 14.04.5, and the installation was a success.
I restarted and logged in, and then, I tried to have some internet. I was looking for WiFi.
But here comes my problem:
I noticed that there wasn't a Wi-Fi connection, so I tried a wired one. But it tries to connect and says that I'm disconnected.
I've read a lot of same problems, but nothing worked till now.
I tried to edit
/etc/NetworkManager/NetworkManager.conf and put
managed=true, but that didn't work...
Does anyone have any ideas on how to fix this?
