View Full Version : [SOLVED] Linux Mint 17 MATE - Wifi won't connect...?

Hi all....just brought my netbook running Mint 17 back from hibernate and now it won't connect to WiFi. I've tried deleting the saved connection multiple times, I've tried turning the WiFi on and off with the laptop's keyboard command, I've restarted the laptop numerous times.....same issue. It will come up, ask for a password sometimes, I type it in and hit connect.....a few seconds later, it just goes back to a "disconnected" state again.

I've restarted the router as well.....still no go.

After I had brought it out of hibernate the first time when the problem started, I had run the "nmcli nm" and "sudo service network-manager restart" commands as sometimes it won't reconnect on return from hibernate and these commands fix it.....now it just won't plain connect whatsoever....any ideas or help would be appreciated! http://forums.linuxmint.com/images/smilies/icon_sad.gif

Sometimes it goes as far as "Requesting Network address" and then stops and goes back to the "disconnected" state? The internet works fine on Wired, just won't connect on WiFi, on any network...

Thanks for any suggestions! :(

Here are some outputs of a few commands for reference in case they give anybody any clues!
