No Firewalls are installed (so I think that is something I don't have to think about).

Internet works fine on Windows.


Any suggestions will be appreciated. Thanks.

You may need to download the wireless card driver. Linux doesn't even know the card exists without it:
Is it inbuilt or a separate card? Even if it's an inbuilt card you still might have to. eg the intel integrated wireless on my dell needed the ipw3945 module from the intel site, but I think ubuntu would come with that by default.

Which wireless device do you have?
Just that little bit of information can get you on-line via wireless. Without that, you cannot get solid advice.

Um, ah, it is like a ball-pen size a little antenna located behind the computer, removable (like I can unscrew it to pack the computer). The computer is HP Pavilion Slimline s3020n. AMD Athlon 64 X2 Dual-Core Processor 3800+ (2GHz). Data Link Protocol Ethernet • Fast Ethernet • IEEE 802.11b • IEEE 802.11g. It is a built-in wi-fi so it is not something I have a model number or anything, there's no driver for it because it is built in (I think).
