Ok, I have been trying for two days to get this up but to no avail. The person has DSL and I placed a router on it to connect a second computer. The modem only handles one connection, so they purchased a Linksys router. I connected their first computer, and it works no problem. I ran the cable from the 2nd pc to the router and I keep getting this "limited or no connectivity" message. The PC is sending out data, but not getting back any. So I tried a 2nd cable. Same thing. I have a hard time believing that 2 cables are bad. I tried a network card in the 2nd pc (it has intigrated) and still the same thing. I don't have a cable tester to test the cables, but I am sure one of them HAS to be good. Anyone have any suggestions? Thanks.
