Does your wireless work at home? Are you sure the trouble is connecting to a public wireless, or could the trouble be with Linux not working with your wireless card?
Also, the silly question, that has gotten people many times--are you sure the wireless card is on? Sometimes, there's a hardware switch and it accidentally turns off the wireless.
Do NOT PM forum members with requests for technical support. Ask your questions on the forum.
