How can I get wireless working on an HP-Mini 110-3500, I have only usb ports
If you have the same 110-3500 that I just got, you do have an ethernet port, but it's hidden. It is located under a cover along the right side of the computer, at the rear - opposite where you plug in the power, and just behind the attachment point for a security lock cable.
I hope that helps. I'm in the process of installing ubuntu myself on one now.
Can you add some hardware information to your question?
From my googling it looks like it could either be a broadcom card or an atheros card. Once we determine which wireless card it is we'll be able to help you better.
Do you have ethernet available? Usually plugging in via a wire and running Additional Drivers does the trick.
