I'm new to Ubuntu and I'm trying to install my TL-WN722N. I'v seen several tutorials on how, but the don't seem to stick…
I've seen that it is supported by ubuntu, I "lsub" it and it does recognizes it, but I can't make the wireless work.
Could some one help me step by step on how to install it?
I'm using Ubuntu 14.04 LTS.
Here is one of the tutorials I used:

How to install driver for TP-Link TL-WN722N on Ubuntu 14.04?
this is what lsus repported:
ernesto@Ernesto:~$ lsusb
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 003: ID 046d:c52e Logitech, Inc.
Bus 001 Device 002: ID 0cf3:9271 Atheros Communications, Inc. AR9271 802.11n
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
This is what i got after checking if the driver loads automatically:
ernesto@Ernesto:~$ lsmod | grep ath
ath9k_htc 75131 0
ath9k_common 25638 1 ath9k_htc
ath9k_hw 446521 2 ath9k_common,ath9k_htc
ath 29006 3 ath9k_common,ath9k_htc,ath9k_hw
mac80211 652718 1 ath9k_htc
cfg80211 494362 4 ath,ath9k_common,mac80211,ath9k_htc
To check the wireless interface, this appears:
ernesto@Ernesto:~$ iwconfig
eth0 no wireless extensions.
lo no wireless extensions.
The message log for the wlan:
ernesto@Ernesto:~$ dmesg | grep -e wlan -e ath9k

the last step didnt do anything:
rfkill list all
I checked for the size:
ernesto@Ernesto:~$ ls -al /lib/firmware/htc_9271.fw
-rw-r--r-- 1 root root 11233 abr 7 23:03 /lib/firmware/htc_9271.fw
I reinstalled the firmwire, rebooted and checked the driver:
ernesto@Ernesto:~$ dmesg | grep ath9k

Without a lot more information, it is impossible to propose a solution. After we have more details, I will edit this answer to add a solution.
Does the driver load automatically, as expected? Check:
If not, try to load it and see if there are any errors or warnings at the terminal:
If it loads without complaint, check to see if a wireless interface, ideally wlan0, was created:
If no wlan0 is created, see if the message log has any clues:
Finally, in some cases, the wireless switch for an internal device will prevent a USB wireless from working. Check to see if the switch is stopping the USB:
I wonder if the firmware is corrupted. I notice:
However, on my system, the size is different:
Please edit your question to add the result of:
If it is not of the size 51272, let's reinstall the firmware package:
Then reboot and check:
With further details, we will proceed.
