I am using Fedora Core 4 with NDISWRAPPER 1.16. I am also using a Belkin F5D6020 ver 3. (realtek) NIC with my 2Wire wireless gateway. NDISWRAPPER sees the driver installed, and the hardware present, but doing a modprobe ndiswrapper the link light does not turn on. The card is working as this works with M$ without a hitch.
Here is the output from ndiswrapper -l
[root@localhost network-scripts]# ndiswrapper -l
net8180 driver installed, hardware present
And a copy of the wlan0 config that ndiswrapper -m made:
[root@localhost network-scripts]# cat /etc/sysconfig/network-scripts/ifcfg-wlan0
# Please read /usr/share/doc/initscripts-*/sysconfig.txt
# for the documentation of these parameters.
Now, I am also using WEP, but this should not prevent the light from turning on (or should it???) and the key is in a file called keys-wlan0.
