I've got 10 PC's on a network, all connected properly. One of the Pc's has a connection to the internet via a modem(broadband not dial-up). I've shared the internet connection and here's my problem....

The shared pc gets its IP address of 192.168.0.1 OK

The rest of the PC's don't pick up their IP so i have to set it manually.

If i ping an internet address (196.25.etc) from any PC i get a reply, but if i ping a www address i get nothing.

The gateway ip on all pc's is 192.168.0.1 and so is the DNS IP

What could be the problem?

I've had the modem connected via a USB cable and connected directly to the switch, with the same result. If i try a broadband router will this solve my problem?

To my knowledge, ICS only works properly with two network cards. One you'd plug the modem into, the other you'd plug the switch with your 10 computers all of which should be able to get the IP using DHCP.

Obviously, a broadband router is a much cleaner and simpler choice. If you already have a switch, then you could pick up a router without an internal switch such as the Linksys BEFSR11.

The gateway ip on all pc's is 192.168.0.1 and so is the DNS IP

Excuse me but you have set DNS server to 192.168.0.1 or you have just specified the gateway ?

If DNS is set already to 192.168.0.1 and doesn't work , try to set DNS of your ISP.
