Linux: How to install TP-Link TL WN821N USB Wireless
I’m disappointed that this doesn’t work out of the box, as I’m sure I consulted several Ubuntu lists which implied it would. Anyway…. After MUCH searching, and several false starts: I downloaded the drivers from wireless.kernel.org by downloading the latest .tar file from http://wireless.kernel.org/download/compat-wireless-2.6 I untarred it. Then opened up a terminal and entered cd Downloads cd compat-wireless-* ./scripts/driver-select ar9170 make sudo make install sudo make wlunload modules=”cfg80211 mac80211 ar9170usb” for i in $modules; do sudo modprobe $i; done Hopefully this should have successfully loaded the drivers. Now we need the firmware I downloaded this from: http://www.kernel.org/pub/linux/kernel/people/mcgrof/firmware/ar9170/ar9170.fw http://git.kernel.org/?p=linux/kernel/git/dwmw2/linux-firmware.git;a=blob_plain;f=ar9170-1.fw;hb=master http://git.kernel.org/?p=linux/kernel/git/dwmw2/linux-firmware.git;a=blob_plain;f=ar9170-2.fw;hb=master There seem to be three versions, and I wasn’t sure which one to use, so I got them all! Then I moved them into the ubuntu /lib/firmware directory sudo mv ~/Downloads/ar9170.fw /lib/firmware sudo mv ~/Downloads/ar9170-1.fw /lib/firmware sudo mv ~/Downloads/ar9170-2.fw /lib/firmware Reboot the PC, and you should have wireless!
