I have a Wireless 3945ABG [Golan] network adapter in my Gateway NX570X laptop. I just installed Ubuntu 14.04. Ethernet works but wifi doesn't. I've tried several methods to try to get it working but it didn't help at all. I think there may be a problem with the card itself. But I can't understand what the code from dmesg is saying. I don't have any hardware off switch; but i do have the keyboard combo switched on, the LED is on for wifi. It is not hard or soft blocked. Thanks for any help!
