Hi there,
I am new to Linux/Ubuntu, so I apologise if this is FAQ (but I have been looking around for several days now and could not find a solution, or at least one I could understand...)
I just cannot get the wireless to connect to the network, even though it looks like the hardware is recognised. It is also not an issue of the router, because I just manage to connect using a windows box sitting right to this one.
If anyone could think of telling me what to do, I am sending the information as required in ticket HOWTO post a Wireless issue
Thanks in advance
