Yet Another Wireless Networking problem

I recently got a Proxim Orinoco a/b/g combo pci card (on a recommendation from this site), and I'm having trouble getting myself on the internet with it. I installed the drivers with MadWifi, and that went fine. Now, if I run rc.wireless ath0, it seems to connect to the network (iwconfig shows data on it and shows the mac address of my access point), but it doesn't seem to want to grab an ip from DHCP (ifconfig still shows as the ip).

I've tried loads of things, running slackware's netconfig script, running rc.inet1 and rc.inet2, resetting my router and my cable modem, all with no results. Now, one odd thing I ran into is that running dhcpd gives me an error, and my dhcpd.conf is completely empty, though I know I've used it before setting up a wired connection. That seemed odd, and I think it could be the root of the problem.

lspci output:

00:11.0 Ethernet Controller: Atheros Communication, Inc. AR5212 802.11abg NIC (rev 01)

Any ideas? Do I have to manually set up my dhcpd.conf? If so, got a tutorial on it? The man page is just a tad too technical for me.

try not using dhcp and do ifconfig eth0 ir whatever your net device is and make sure you add your routers IP address if /etc/resolv.conf it should be one line that says:

or whateve ryour routers IP is.

Well, I added that to my resolv.conf, did ifconfig ath0, and set my router to statically alocate that IP to the MAC address that iwconfig gives me, but no dice. Links now gives me a "network unreachable" error. I also ran rc.wireless, rc.inet1, and rc.inet2 to be safe, but to no avail. I tried iwconfig ath0, but that lost the network.

I'm sure I'm missing something.

(Edit: ath0 IS my interface, I'm sure of that)

you are going to have to do this:

iwconfig ath0 essid "Youressid"
iwconfig ath0 enc Yourkeyhere <----if you use encryption
dhcpcd ath0

EDIT---Make sure your router has dhcp enabled when using these commands

'ifconfig' should only show as the IP for the 'lo' interface: not for the ath0 interface. Are you sure the connection is coming up properly?

Well, NOW it only shows for the lo interface, ath0 is now, which is what I set it to.

And I know the network connection is working. I can access my router at, and all of my iwconfig stuff is fine, including the MAC address of the access point.

I just can't connect to the internet. For no real good reason.

Oh dear, I found the problem, and it's so stupid I may just have to seppuku. And pay all of you guys for the time I wasted.

I was typing dhcpd instead of dhcpcd.


Well, I learned a bit about networking. Thanks a lot for the help, despite the anticlimactic ending.
