I'm trying to share the net connection with my xbox. The modem connects to the PC via USB. Then the xbox is hooked on to the NIC. I already have it set up so I can FTP back and forth. The problem is when the xbox is turned on I can't access the internet on the PC. I went to (Network connections) and seen this: Internet Gateway: L.A.C. on Linix IGD (this connection disables and reconnects when you power off the xbox) LAN or High Speed: L.A.C (this is the xbox connection) & L.A.C #4 Actiontec Gateway #2 (this is the modem connection) When I try to go into the Actiontec and check the box for ICS I get an message saying it will us IP 192.168.0.1 then anerror message saying: ICS can not be enabled. A LAN connection is already configured with the IP address that is required for automatic IP adressing. The xbox LAN is set to 192.168.2.1 I tried setting it to (obtain automatically) but got the same error message. I'm lost now I would like to get this working instead of buying a router. I have dsl with sprint if that helps any.
This seems to be an all too common problem man, same thing happened to me, but with 3 computers. i cant see why you are trying to use the xbox as an internet gateway tho, you looks like your trying to connect from pc through xbox back to pc for some reason :s set it up like this. delete all the connections and your internet one remake em 1 by 1 make your net connection right name it BT or WANADOO or w/e then enable modem, name it modem, enable your network card name it xbox, now you should have no gateway ok, delete the gateway thats your problem. Now go to the properties on Modem and go to network connection sharing and share with xbox. unset the ip on the xbox it should auto assign one to it. hope this works!
