just asking, if i say only had 1 lan coming in from a friends ( next door ) is there a way to plug it into a 4 port router and use the router asa splitter so i can run up to 3 other computers from the 1 coming in.. ( pluged into the lan port not a adsl port)
I've done that myself on the odd occassion when I've needed a switch
Go into your router's lan settings and look for an option to disable its DHCP server. Other than that you would need to change your router's IP address if it conflicts with your mate's router or anything on his network.
