It used to work but I guess one of the updates broke it. I can connect to the wifi on my phone and other OS's. Unsure of what would cause this. I have tried deleting the profile for each connection and re-entering passwords but nothing. IF I remove passwords for the connections it will work.

  • Recently I had a similar problem. I had disabled WMM on the router and this caused the problem. There was some info about it in `dmesg`. Try to sign into the network and then check `dmesg` for any new info. If you don't find any useful info, please post the info described here: http://askubuntu.com/questions/425155/my-wireless-wifi-connection-does-not-work-what-information-is-needed-to-diagnos thanks! – mchid Jan 09 '17 at 19:59
  • I have WMM enabled. I have this error "ADDRCONF(NETDEV_UP): wlp3s0: link is not ready" when I run dmesg – Derek Jan 09 '17 at 23:51

Try this if you have network-manager enabled : 

sudo nmcli dev wifi

to find your wifi ssid and

sudo nmcli dev wifi connect <your ssid> password <your pass>

Looks like network-manager is waiting for root permission.

  • It worked! Thanks, although the only bad thing is that, in your bash history the wifi password, will remain visible. – Edenshaw Nov 27 '17 at 12:44

If you don't want your password to appear in your history just leave out the password part and add the -a option and it will ask for it after you hit enter:

 sudo nmcli -a dev wifi connect <your ssid>

From man nmcli

 -a | --ask    When using this option nmcli will stop and ask for any missing 
  required arguments, so do not use this option for non-interactive purposes like
scripts. This option controls, for example, whether you will be prompted for a 
password if it is required for connecting to a network.

In my case it was something with the KDE Wallet system. I've installed some updates, and those seem to wipe my old wallet and make it corrupted - ie the wallet could not been opened.

The fix was to create a new wallet and set it as default.

It happened to me and I hadn't done anything. Turned out there was something wrong with the "Bbox" from Bouygues ISP. After 2 hours on the phone they sorted it out.
