I have set up 3 Dell computers on a wired network through a Linksys DSL router. Two of them are about 50 feet away from the router and the third one is next to it. I have no problem with the third computer, goes on-line fine with 100 Mbps NIC speed. The other two computers, I was able to make them get IP addresses from the router after setting the NIC's speed and duplex to 10 Mbps full. When set at default (Auto) they gave unpredicted results. Typing IPCONFIG will give either 0.0.0.0 or IP addresses that didn't start with 192.168.1.x. When I set up one of these computers next to the router, then it works fine like the third computer. Do I have problem with weak signal? Could this problem be fixed by connecting them to a switch/hub from the router?
Any help is greatly appreciated.
