I'm currently running Ubuntu 14.04.3 with kernel version 3.19.0-25-generic and use the TP Link WN725N for Wi-fi.
I followed this guide for the driver installation otherwise I'd get barely any signal:
I installed 16.04 with kernel 4.4 a week ago but the adapter didn't work out of the box so I followed the above method again but it didn't work. I was, like before, barely getting any signal.
Any way to get the drivers working for kernel 4.4?
