buffalo g54 airstation + slackware 10.1

Ok im trying to hook up my buffalo g54 airstation up to my ethernet
connected PC, thats running slackware. I log into the router fine, and
go through the wizard. 1st I click on the cable modem button, then i
click on the automatic IP assignment option. The wizard the proceeds to
say..
"WAN side IP address setup is being completed.
Wait for a moment while the next page loads."

I then get this message
Enable the DHCP Server

Changing settings to notify of a domain name obtained by WAN side DHCP
server.
* Renew the LAN side PC's IP Address to obtain the domain name.
Im not to sure how to renew the LAN side PC's IP adress, so i tried
killing the dhcpcd process, then i tried to run dhcpcd again.

Next I proceeded with the setup wizard, this is where i get my error

1st it says
checking for Intenet connectivity...
Cable(Idle) it switches between idle and discovery

after about 30 seconds i get this..
The connection was unsuccessful...
Cable(Failed)
,please confirm.

any help will do,
thanks,
