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:

how to install tp link wn725n wifi usb adapter on ubuntu Ubuntu 14.04.3 LTS

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?

  • Are you asking about a USB or an internal PCI adapter? If it is about USB, then post output of lsusb.

    FWIW I think the WN725N 0bda:8179 is the rtl8188eu chipset. Out of the box for me, Ubuntu 16.04 is using the r8188eu driver and it seems to work. This post claims that the low signal strength is just a display issue. The device doesn't show up in iw dev though and can't be configured for hostapd. With earlier kernels, I installed from TP-Link's source. But it says it only supports up to 3.19.3.

try the following steps, it worked for me -

sudo apt-get update
sudo apt-get install linux-headers-$(uname -r) build-essential git
git clone https://github.com/lwfinger/rtl8188eu
cd rtl8188eu  
make all  
sudo make install  
sudo insmod 8188eu.ko
