ICS doesn't work!

[markjs]

I have two machines and one is hooked up via USB to a Direcway 2 way sattelite modem. Since the connection is USB only it was not possible to use a router so we used the router as a hub. The hub is connected to the internet machine via a standard NIC and a cable but the second machine has a generic Linksys wireless card, and the hub (router) is a wireless one. Internet connection sharing used to work (both machines run XP pro), but it stopped. Both machines are on a viable network and all the settings are right enough to enable both machines to view each other's shared folder. The thing is though that even with ICS enabled and no firewalls the internet connection only works on the parent machine. So on the one hand I know for a fact the network is set up but on the other hand it doesn't work. I have done a fresh Windows install on the parent machine, and the last hope if you guys fail to provide an answer is complete Windows reinstall on both machines

It could be ICS or your router not doing its job of acting like the hub. Is there no way to hookup the second machine via a wired connection directly to the parent instead of through the router? That would help you rule out the router.

Switch I would think instead of a hub and I would guess you left your DHCP server running on the router side of the device, and it is handing out IP's on a different segment than your DirecPC host machine. Forget about sharing and internet for now. Start pinging. If you can't ping from client machine to host machine, AND you have no firewalls stopping ICMP echo's, then you've got a problem. If you get Destination host unreachable on the client or Host machine when pinging the other then your IP's are on different networks.

Remember I am not using the router at all. Just using the router as a hub so nothing is in the WAN port.

Strangely when I try and ping the parent machine I get this:

E:\Documents and Settings\BLS> ping 192.168.0.1

Pinging 192.168.0.1 with 32 bytes of data:

Reply from 192.168.1.100 Destination net unreachable.
Reply from 192.168.1.100 Destination net unreachable.
Reply from 192.168.1.100 Destination net unreachable.
Reply from 192.168.1.100 Destination net unreachable.

Ping statistics for 192.168.0.1:
Packets: Sent = 4, Received = 4, Lost = 0 <o% loss>

Approximate round trip times in milliseconds
Minimum 0ms Maximum 0ms Average 0ms

And when I ping the slave machine it won't ping, but yet I can still read the shared folders and share files from either machine. What gives?

Problem solved! Turns out contrary to ICS's own instructions I had to set the client machines IP to 192.168.0.2 and had to set the DNS and Gateway to 192.168.0.1

Yep, you were running two different networks though I would imagine you still need to turn off the DHCP server on the router. That function runs regardless of whether your using the WAN port or not and again, your ports are switched. Small thing but it's not a hub, unless it is a REAL old router.
