To workaround this bug. Create a file named: /etc/modprobe.d/wifi_bug.conf
Add the following lines to the file: options iwlmvm power_scheme=1 options iwlwifi bt_coex_active=N swcrypto=1 11n_disable=1 Set the file's ownership the same as other files in that folder. Reboot. Please note though that this fixes the issue, but prevents N mode from working, so you are stick with B and G modes. Otherwise I'm very disappointed that no one cares about this bug as I would be glad to provide all the information I'm able to to get this fixed. The other thing that makes me very sad is that this was already working perfectly in the past with 12.04 and now it isn't. This really sounds to me like a step backwards...

This wifi card was working for me with Ubuntu 12.04 for several years before flawlessly. Now I installed Linux Mint based on Ubuntu 14.04 and it is now randomly disconnecting. When it disconnects I disable wireless in the NM applet and enable it again and wifi reconnects. Logs regarding the disconnect and the reconnect are attached to the report. The disconnect happens 10 to 60 minutes after it was connected or reconnected.
