Comment 55 for bug 1349572

The easiest way I know of for you to test the 3.16 driver with 3.13 is by using the drivers from the backports project. Unfortunately there is no prebuilt version for Ubuntu, so you'll have to manually build and install the drivers. If you want to give this a try see https://backports.wiki.kernel.org/index.php/Main_Page.

Ultimately if 3.16 gives a more stable connection than 3.13 I'd like to backport the relevant changes to 3.13, but the problem is that I don't know yet which changes need to be backported. If it were only due to the -9 firmware then I believe that's easily backported to 3.13, but based on your results so far that doesn't seem to be the case.
