I've asked before but didn't get an answer IIRC! basically I've my powerbook feeding off my wireless router, I have a run of the mill Ethernet cable attached into my Xbox running Xbox Media Centre. Which has the ability to go online, IF the network settings are right. So, my Xbox's IP is 192.168.2.3. My wireless router is 192.168.1.1 My PowerBooks wireless is 192.168.1.2 My PowerBooks Ethernet is 192.168.2.1 The subnet is 255.255.255.0 (I think). Internet sharing via Ethernet is activated. I just have no idea what i'm doing. on the Ethernet IP settings on OSX if i change the router IP to 192.168.1.1 then I get an error saying that the router is not on the subnet? help!
