Panama-Buena Vista is also on Aruba and has experienced weird issues, although I think they were able to get them worked out. The 7260 seems to prefer 5GHz, so definitely make sure you are connecting to a capable 5GHz SSID.
You can also try a newer driver from an upstream kernel through the backports project. To do this, first go to the backport page here:
https://backports.wiki.kernel.org/index.php/Main_Page then click on the link under "Download" for the current release. Once on that page, download the latest one at the top (I used
backports-4.1.1-1 for this test run) and extract the downloaded file to your Home (user) folder, then follow these steps:
- Open a terminal (ctrl-alt-t)
- cd backports-[tab] (should autocomplete to the version you downloaded - if not, start typing the version and press tab to complete, or type out the full version)
- make defconfig-iwlwifi
- make
- make install
- reboot
After this is done, test to see if things are better.
