ICS Issues from node

Question

I have a USB modem connected to my desktop for an Alltel Wireless Air card - it's basically a very fast dial-up connection. I have the connection shared and my computer connected to a router (with DHCP turned off), and then another computer also connected to the router.

From the node, if I were to try to ping yahoo.com I would be able to resolve the host but get Request Timed Out errors. I can ping the host computer from the node and visa versa, and i can use the internet fine from the host computer. Any ideas as to why I cannot connect to the outside world from the node computer, but I can get DNS?

Answer 1

This would normally be a gateway issue. If the DNS is getting through the only reason you can't get out is that your computer does not know the correct gateway to the internet.

You said you have connected the router to the shared computer, I would say, remove it and see if a computer can connect and get out. Once is does you can then setup the router but be sure your ICS is working correctly first. (using a computer connected directly usually is easier for troubleshooting.)  

You might even try allowing the router to setup the second node, on a different segment. Leave DHCP enabled but be sure it assigns to a different network segement entirely. (if your ICS supplies an ip range of 192.168.1.1  set the routers range to say 192.168.10.x)  

But do check that your second computer shows the ICS machines IP as the gateway! (you may have to manually set that in the router)
