Try the stuff here.

http://www.linuxwireless.org/en/user.../Drivers/ath9k

You need wireless tools once the interface is up. the usual enquiries are

iwconfig wlan0
iwlist wlan0 scan |less

Have a go from the page, and post the results of those if you get stuck.

Please use code-tags for commands and output of commands, that will make your posts much more readable and avoids those annoying smilies in the text. To use code-tags use the #-sign above the advanced editor and put your code/output between the generated tags. To demonstrate that I have edited your posts and added the tags.

Radio is on and the kernel module is loaded as it's picking up two access points. You simply need to associate it with one of those - not knowing what distro you have doesn't help... you need something like networkmanager or wicd to connect to your AP.
