TP-Link TL-WN722N USB wireless adapter Beagle Bone Black

So you have a Beagle Bone Black (BBB) and bought the TP-Link TL-WN722N wireless adapter. WOOT me too. Then you went off and installed Debian onto your BBB. Wow you and I are like twins. But now you can't find anything that points you in the directions on how to get your newly found wireless adapter working darn internet. GOOD news this will help you with that.
Note: I'm using Debian distro Wheezy-bbb

Working assumptions you have installed Debian on to your BBB and you do have a TP-Link TL-WN722N. If any of these assumption are wrong then I can't say these steps will work.

Step 1: Make sure your source.list looks like this

cat /etc/apt/sources.list

deb http://ftp.us.debian.org/debian/ wheezy main contrib non-free
#deb-src http://ftp.us.debian.org/debian/ wheezy main contrib non-free
deb http://ftp.us.debian.org/debian/ wheezy-updates main contrib non-free
#deb-src http://ftp.us.debian.org/debian/ wheezy-updates main contrib non-free
deb http://security.debian.org/ wheezy/updates main contrib non-free
#deb-src http://security.debian.org/ wheezy/updates main contrib non-free
deb http://ftp.debian.org/debian wheezy-backports main contrib non-free
#deb-src http://ftp.debian.org/debian wheezy-backports main contrib non-free
deb [arch=armhf] http://beagle.s3.amazonaws.com/debian wheezy-bbb main
#deb-src [arch=armhf] http://beagle.s3.amazonaws.com/debian wheezy-bbb main

Step 2: If you had to change or add things to the source.list you will need to update your packages

sudo apt-get update

Step 3: Install the wifi libraries.

sudo apt-get install wireless-tools usbutils

Step 4: Download and install the firmware for the wifi card.

sudo apt-get install firmware-atheros
sudo wget http://linuxwireless.org/download/htc_fw/1.3/htc_9271.fw
sudo cp htc_9271.fw /lib/firmware

Step 5: Adding the adaptor info to the interface file.

sudo vi /etc/network/interface

Add to the bottom of the file.

# The wireless interface
auto wlan0
iface wlan0 inet dhcp
wpa-conf /etc/wpa.conf

Step 6: Plug the Wifi card in.
Step 7: Make sure system sees the wifi card.

sudo iwconfig

root ~ # sudo iwconfig
wlan0     IEEE 802.11bgn  ESSID:"crash_wireless"  
          Mode:Managed  Frequency:2.437 GHz  Access Point: 00:14:BF:05:4A:05   
          Bit Rate=24 Mb/s   Tx-Power=20 dBm   
          Retry  long limit:7   RTS thr:off   Fragment thr:off
          Encryption key:off
          Power Management:off
          Link Quality=70/70  Signal level=-30 dBm  
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:264   Missed beacon:0

Step 8: Make the wpa.conf file.

sudo vi /etc/wpa.conf

network={
    ssid="TheSSID"
    proto=RSN
    key_mgmt=WPA-PSK
    pairwise=CCMP TKIP
    group=CCMP TKIP
    psk="ThePassword"
}

Step 9: Lets start this thing.

sudo ifup wlan0

Step 10: Lets make sure we are connected

Step 11: Do a dance cause it is connected. If not try turning off the BBB and turning it on again.
