Hi all,
I had a tough time getting my wireless USB TEW-229UB dongle working but I finally got it. I'm creating this post for anyone else who is trying to install wireless drivers in Fedora core 5.
I used the NDISWrapper to install the windows driver under Fedora core 5. Download and install the NDISWrapper.
Next run the following:
su
ndiswrapper -i /path/to/driver.inf (this folder should include all files that come with the inf file)
/sbin/modprobe ndiswrapper (you should see wlan0 created in syslog (ie.. /var/log/messages))
/sbin/iwconfig wlan0 mode (managed or ad-hoc) essid linksys
/sbin/ifconfig wlan0 up
/sbin/dhclient wlan0
that should get you online
