sorry if this is a little bit of threadjacking, but since i'm having about the same problem i'll do it anyway. i have the same problem and i setup a wireless router (linksys wrt54g) with DHCP turned off. it works to connect to the router wirelessly and get the inet wirelessly (the cord for the wall port goes into one of the 4 non-inet ports instead of the reg inet port). but my roomates desktop fails to get inet when i connect to the router through a wired connection. i think the router is assigning 192.168.1.x or whatever to the wired devices. Any way to turn that off? would mac address filtering have something to do with it?
