I updated Ubuntu to 13.10 last night and wifi was working fine until I went to wake up my computer this morning and no WiFi connection. I am on a iMac with Qualcomm Atheros AR93xx Wireless Network Adapter [168c:0030] (rev 01). The only solutions I have seen so far are for broadcomm WiFi drivers. There is no wifi driver in addition drivers only graphics drivers. Not sure how to fix this, Any help would be greatly appreciated. UPDATE: WiFi works after reboot but doesn't after being put to sleep nor does Ethernet connect after sleep.
