There is a switch that sets whether the ath9k uses 2 channels, CONFIG_ATH9K_CHANNEL_CONTEXT. If that isn't set to 2 for the kernel you are running, then you won't have access to the two channels. Try going to /boot and running cat config-[for the kernel you are running] | grep -i ath9k If it isn't set, you could compile a custom kernel to enable it. -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
