[CentOS] Wireless connection issue - athero 9300 pci wireless card

Hi all,

I am new to CentOS. I built myself a desktop with an additional PCI wireless card 'TP-LInk WPN3800', which I have checked needs an ath9k driver. * **04:00.0 Network controller: Atheros Communications Inc. AR9300 Wireless LAN adaptor*

Following the wireless connection tutorial on CentOS wiki, I have both kernel-devel 2.6.6 and ath9k installed. Then I tried * $ modprobe ath9k

*but nothing happened.

Then I input

*$ service NetworkManager start $ chkconfig NetworkManager on

*to access the Network Manager and no wireless connection options appear.

I do not think it is a big problem for you guys, but I am really a beginner. Please share me some solutions for that.

Thank you!
