I've just installed 12.04 in a dual boot with Windows 8 via a USB. The important point is that my laptop doesn't have an Ethernet. When I booted to the USB, wireless networking worked. Now that I've installed 12.04 on a partition on the hard drive I can't get wireless networking to work.
Any suggestions on how I should fix this?
