Activating eth1/wlan0 for intel 2100 wireless

Hey guys,

I've got a laptop with ethernet/intel 2100 wireless, running slackware 10. I installed the drivers for the centrino wireless from the sourceforge project (0.47) and the modules load on startup.


Those are the relevant modules that are loaded.

My problem is that eth1/wlan0 (whichever would be my wireless network interface) do not exist. In KDE's info center it lists eth0 and lo as the only interfaces. I can go online using an ethernet cable, but not using the wireless.

If I run ifconfig I also only get eth0 and lo. So if I try ifconfig eth1 or wlan0, I get the error message "error fetching interface information: Device not found"

Following the directions in the 2100 drivers installation, I made a file /etc/sysconfig/network-scripts/ifcfg-eth1 with this in it:


modprobe ipw2100
ifconfig eth1 up

iwconfig eth1 essid group (I read somewhere that helps)

I run this in my /etc/rc.d/rc.local startup script.

My rc.inet1.conf has eth0 configured right, it works fine using static ip. For eth1, I left everything blank except:


I also did remember to download the Intel firmware from their website and put it in the folder /usr/lib/hotplug/firmware .

So is there a way I can get eth1 or wlan0 to show up to ifconfig/the network interface list?

I'm smart - I just realized I need the 2200, not the 2100. Will test that and see how it goes.

eth1 now shows up in ifconfig, but not in KDE's control center module.

I can ifconfig eth1 up and down, but can't go online using it. I'm basically talking to myself here

I'm not sure whether or not the DHCP server will tell your client about the router, or whether you're even using a router, but if you are try typing route -n just to make sure that a route is set up to go through your router with the destination as So it should be something like:

Destination     Gateway         Genmask         Flags Metric Ref    Use Iface   U       0        0        0    eth1          U        0        0        0    lo             UG      0        0        0   eth1
if you don't have a line like the last one, and you are connecting to the net through a router, try typing

route add default gw
if your router's IP address is

Hope it helps, it was worth a shot.

Edit: sorry the code tags are messing up a bit
