Ok, four computers are all LANed together. 3 of them all connect the internet, except for mine now. They are all under a switch box, 2 computers under 1, which is a total of 2 switch boxes. It will not automatically detect the IP addresses and such. I have tried manually assigning it one, yet it still won't work. I have tried pinging the IP address, which recieved 4/4 packets. But when i tried pinging the gateway, it recieves 0/4. Can anyone help?
