Welcome to LQ
I have made this card working under Slackware using ndiswrapper, but it will be quite the same for your distro.
First of all you need to install your kernel sources if you haven't done this yet. Use Fedora's package manager for this task (rpm or yum).
Then download ndiswrapper from
http://sourceforge.net/projects/ndiswrapper/ Extract it and from the directory that was created run:
as root. In fact it's better to do the whole job as root since most of these commands need root priviledges.
Copy the WinXP drivers from the CD that came with your card (or just mount the CD) and run:
Code:
ndiswrapper -i /path/to/WinXP/drivers/GPLUS.inf
Of course change "/path/to/WinXP/drivers" with the path to the directory you copied the drivers, or the path to your mounted CD. Mind also that the name of the .inf file might be different and it's case sensitive.
Then run:
to see if the driver was loaded. You can also run:
to see in the last lines if the driver was loaded.
If there is no error you can load the module into the kernel:
Code:
modprobe ndiswrapper
Check again with dmesg and if there is no error you will see also the interface assigned to your nic.
Then use Fedora's network tool to configure your card. Perhaps you'll need wireless-tools which you can install with your package manager.
You can take a look at the wireless networking forum in LQ, or do a search since there are lots of questions avout ndiswrapper.
Here is the installation guide for ndiswrapper. If you have any question just post it here so we can help you.
Good luck.
