Fedora 15: Fix TL-WN722N after updating kernel

If this USB wireless adapter looks familiar, then not having internet access is also very familiar to you after updating your kernel to 2.6.40* version.

Solution:

1. Download from here the latest firmware for your adapter (if your adapter is different but also from TP-LINK then scroll down for more info).
   It seems the webpage has been down for a while. Here you can download the same file hosted in my webpage if necessary (MD5SUM: 76c902360ef8a095133258fd0d287292).
2. Open up a terminal where you downloaded the file and copy it to /lib/firmware/ as root:
   sudo cp htc_9271.fw /lib/firmware/
3. Reboot. Unplug and plug again the device. Enjoy!
