There is an easier solution: update the driver. 3.13 is old and it uses and old firmware. You can update your driver with the help of backport and it will dramatically improve the behavior of WiFi. I also tested 3.16 (14.10) and latest driver with backport. The latest backport behaves *much* better.

This laptop is a Dell XPS 12 (haswell). With the -8 firmware, it will connect fine to wifi for 30 or 40 mins at a time, then will start dropping connections repeatedly. Even modprobe -r unloading and reloading doesn't fix the issue, only a reboot will temporarily solve it for 40 mins at a time. Moreover, here is what's strange, is during these episodes of disconnection it seems to affect the actual router (2Wire), as the other devices in the house will also start to have issues (very slow connections, limited range,etc). Once I reboot this laptop everything and all devices will return to normal. This issue has been fixed by me manually removing the -8 firware from /lib/firmware and letting the -7 firmware load instead. Since that has been done there has not been a single issue of this happening (now going on 4 days). let me know if there is any other information you would like me to provide.
