This problem started to occur after I upgraded to 15.04.
I connect to wifi, after some time it disconnects, and after I try to re-connect it shows following:
* Blured area are wifi names.

Ok, as Guest I am unable to edit my Answer so I put it in this post. For me it worked out just typing:
sudo apt-get install -d --reinstall network-manager
sudo apt-get install -d --reinstall plasma-nm
Sorry for the Post before...

if that is not working try this
sudo sh -c 'echo "options iwlwifi 11n_disable=1" >> /etc/modprobe.d/iwlwifi.conf'
described in Unstable wireless with Intel 7260 + iwlwifi after upgrade to 15.04 or here.
Good Luck
