View Full Version : [lubuntu] Wifi not working after installing 12.10, but working on live usb

I just installed Ubuntu 12.10 using a live usb stick. During this installation, the wifi worked correctly and connected to the network and downloaded language packs and packages. However when I booted in to the system after installation had finished, the wifi card is recognised, but it does not find any wireless networks. I took a wireless dongle out of one of my other machines and this works fine, so it suggests it is not liking the wireless card for some reason. Does anyone have any ideas?
