You can try this option. Run in terminal sudo tee /etc/modprobe.d/iwlwifi-opt.conf <<< "options iwlwifi 11n_disable=1" and reboot. If this does not help, some other options can be used.

This is a new feature from 15.04 in ubuntu-driver-common. Ubuntu will now automatically try to find hardware and their additional drivers and packages to have a better more stable (hopefully) system with less user hassle. For example in 14.10 nvidia optimus GPU drivers had to be installed from a separate PPA but in 15.04 the system knows that they are there ...
