I am having issues with my wireless connection. My connection is constantly disconnecting, then attempting to reconnect, reconnecting momentarily, then disconnecting etc. on times scales that range from seconds to minutes. In the meantime, needless to say I'm having significant packet loss. I'm running Ubuntu 14.04 64bit, updated and upgraded to today. Here is my card and driver:
delta@sager:~$ lspci -vq | grep -i wireless -B 1 -A 5
04:00.0 Network controller: Intel Corporation Wireless 7260 (rev 73)
Subsystem: Intel Corporation Dual Band Wireless-AC 7260

Here is my kernel:
delta@sager:~$ uname -r
3.13.0-34-generic
None of the other machines on my home network are having these issues. Windows Vista is networking without issue for goodness sake ;-)
Here is a small clipping from the output of dmesg. As you can see, I am getting a cfg80211 message of some sort over and over again (FYI, I've replaced my MAC address with a series of dashes, so anytime there is a ---------------, that was where the MAC address was:

I've poked around on AskUbuntu, and have not found any adequate solutions; have also found similar threads that were left unanswered.
Any advice/experience/threads I might be able to pull on would be greatly appreciated. In your opinion, is this a kernel issue, hardware issue, etc.? Thanks in advance.
