Hi out there, can anyone help an old man??.
I've recently bought an ASUS notebook with xp installed on the "C" drive. I can access the internet with no problems.
I then installed "Ubuntu" on the "D" drive. This works well, but I cannot access the Internet. I have gone to System/Administration/Network Connections/Wireless/Add, and I need to find the information to access the net, i.e "Setup details and"Key".
Be very grateful for any help
