jhouse, thank you for reporting this and helping make Ubuntu better. Could you please restore your system to the default firmware and kernel provided by Ubuntu, and then test the latest upstream kernel available (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-3.15-rc5

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results. Thank you for your
understanding.

  Un-tar the downloaded files:
  tar xvf backports-3.13.2-1.tar.xz
  tar xvf iwlwifi-7260*

  Then build backports for iwlwifi:
  cd backports-3.13.2-1/
  make defconfig-iwlwifi
  make
  sudo make install

  Then copy the firmware ucode file to /lib/firmware
  cd ..
  cd iwlwifi*
  sudo cp iwlwifi* /lib/firmware
