Well, first you need to know the manufacturer and model of your wireless card. If you don't already know that, type 'lspci' (if internal) or 'lsusb' (if external), without the single quotes, in a terminal. Look through the output and find your card, is should say "Network controller" near the beginning but it might not. If you can't find it, post the output here. The easiest way to do so is:
and then copying the resulting file(s) to a flashdrive so you can copy and paste from windows.
After you know the manufacturer and model then search google for: "fedora manufacturer model
driver" without the quotes. If that gave you the name, but no link to the driver's rpm (or an old rpm), then search for "fedora 10 driver
rpm" without the quotes.
After you have the rpm, copy it to a flashdrive and boot back to Fedora. Use the rpm command to install the file like this:
rpm -i /path/to/driver.rpm
If this is confusing I apologize, I'm not very good at writing directions.
