FC-4 Wireless Problem

First, don't let that error throw you. If the box is checked in the "system-network-config" app then it pegs on my laptop but I can still connect.

I am assuming you have installed and configured ndiswrapper to be able to use your wireless card. If not there is a very good link here...

Even after all that - you will still get that error. I know, I spent a little time looking for a fix all over the internet and nothing.

Next, you need to setup your wifi card to connect to your network. Everytime I tried to use the network applet it gives the error and does not configure the card. The commands I need I put into the /etc/rc.local which I have listed below.

Set your essid
Set your WEP key
Bring your interface up
Tell wlan0 it is dhcp

Now, I am connected. You should be too. Take a look at the man pages for iwconfig and the other wireless utils for all of the parameters.

One thing about having 2 interfaces, you need to make sure your kernel routing table is set up correctly if you want to surf. Make sure the correct one is set for the gateway. Usually, whichever one is going out to the internet I make sure there is no gateway set. In the case below eth0 is heading out to the net and wlan0 just goes to my network drive. If there is a conflict here you won't get out.

0.0.0.0         192.168.1.1     0.0.0.0         UG        0 0          0 eth0

I don't know if this is the easiest way, but hope it helps.
