Ethan: We recently incorporated some updates in 14.04 specifically for disconnection issues with Intel 7260 wireless. Could you ensure your system is fully up to date, reboot (ensuring that you use the official 3.13 kernel for trusty and not any newer version you installed for testing), and let me know if the situation improves? If not we can start trying to figure out what changes from newer kernel versions fix your issues.
Everyone else: unless you have the exact same machine as Ethan has, please file a new bug report if you haven't already by running 'ubuntu- bug linux' from a terminal. Feel free to subscribe me to your bug reports.

On several occasions I have been unable to reestablish an association with the AP without rebooting. This occurs even if the laptop is within a few feet of the AP. I did not have this problem on 12.04 with a quantal backport kernel.
