I'm new to ubuntu, so I'm learning. I have hp 655 with amd processor. I had win 7, and i bought tp link wn722n for better wifi signal. Now I can't use it, because I use Ubuntu and don't know how to install drivers. I tried this steps ubuntu questions but that didn't help. Can anybody help me? The results are:

Bus 002 Device 003: ID 0cf3:9271 Atheros Communications, Inc. AR9271 802.11n

I suggest you blacklist the quirky Realtek 3290:

sudo -i
echo "blacklist rt2800pci"  >>  /etc/modprobe.d/blacklist.conf
modprobe -r rt2800pci
exit

Your TP Link uses the driver ath9k_htc. Let's load it and see if there are any errors:

sudo modprobe ath9k_htc
dmesg | grep ath
iwconfig

In order to get ath9k_htc to work correctly, let's remove backports. Please do:

cd ~
ls | grep back

The ls command will verify that we are in the correct directory. If the command returns: backports-3.16-1, then let's remove it:

cd backports-3.16-1
sudo make uninstall
sudo depmod -a

Reboot and show us:

dmesg | grep ath

The driver ath9k_htc should load without any complaint.
