http://ubuntuforums.org – I am completely new to Ubuntu, so please give me easy to follow steps. So, I have just installed Ubuntu 10.10 x64, but cant get my wireless to work. It detects my networks and tries to connect to them - ethernally, whithout success. I have tried it on an unprotected and on a WPA2-personal protected network with the same results. My card is a RaLink rt3090. Please, help me connect wirelessly __________________________________________________ _________________________________________________ sudo lshw -C network *-network description: Ethernet interface prod (HowTos)
