Help- TP-Link wireless card TL-WN851N doesn't work with ath9k driver
I am using ubuntu 9.04, but cannot establish a wireless connection.
I am using an atheros based wireless card, but the ath9k driver does not seem to work.
I downloaded and installed compat wireless and managed to uninstall the ath9k drivers. But am unable to install the ath5k drivers. If I reboot the system ath9k automatically reinstalls.
I don't know what to try next, do I need an NDIS wrapper?
I am new to Linux, so any help would be much appreciated.
