    AR93XX Wireless LAN problems

    I am having problems with my wireless connection on my desktop pc. It says it is connected to my router but I cannot make any internet connections. The machine is dual-boot w/ Windows XP and ubuntu 12.10. On Windows XP, I have no problems connecting and browsing wirelessly so I know that it's not a problem with my wireless PCI card. On ubuntu 12.10, I can connect to the internet with a wired connection but when I switch over to wireless, it says it is connected to my router but I cannot make any internet connections. Below I have printed some debug statements.

    hmmm...I could really use help here. No replies to my post. Please let me know if more info is required.

    Is anyone out there having any problems w/ ubuntu 12.10 and AR9300 Atheros chipset using ath9k?

    Re: AR93XX Wireless LAN problems

    For those who might encounter the same problems as I did, I was able to resolve my connectivity issues with the installation of compat-wireless aka linux-backports-modules-cw that matches with my kernel from ubuntu repository. Alternatively, can install by building and loading the compat-wireless drivers from, http://linuxwireless.org/en/users/Download/stable/
