Although I personally never had this problem, I did a little digging and the closest I could find is this.

Here is the gist of the solution

The smarter way to save the security key, along with other settings is to do it via Network Manager settings (nm-applet menu > Edit Connections > Wireless tab > double-click your connection > Security tab). That is the frontend to handle those key files.

Assuming something might have broken in Network Manager installation while upgrading, you may try to completely purge it, then re-install it. To download the packages in advance (since you’ll lost internet connection as soon as you purge it) -

sudo apt-get install -d --reinstall network-manager network-manager-gnome

Then to purge it -

sudo apt-get purge network-manager-gnome network-manager

To reinstall it (I suggest a reboot in-between) from the downloaded packages, simply -

sudo apt-get install network-manager-gnome
