Problems With Connection Sharing

[Vince4Amy]

I'm having some problems with the new network I've setup in my house. For some reason I cannot share the Internet Connection as I used to be able to. Here's a diagram of how my network is set up.

As you can see from the Diagram above the Internet connection is coming from a USB Speedtouch 330 Modem. The connection is then shared wirelessly from the Main computer to the Netgear ME102 Access Point.

After this there is a wireless connection to the secondary computer, the Secondary computer has a Wireless USB adaptor, this works fine and the Internet Connection shared from the main computer works on the Secondary computer.

There is a third computer connected to the secondary computer which is wired using crossover cable, all I get from this is Limited or No Connectivity and the third computer will not detect an Internet Connection.

The Main & Secondary computers are in a Workgroup, the third is not, but even if it is in the Workgroup the Message still displays, also to note the Third Computer used to work by using the secondary computers Internet Connection even without being part of the Workgroup, which is what I want it to do now. The old configuaration was an additional Network card in the Secondary computer and another ME102 Access Point Connected to the secondary computer.

All computers have a Fresh Install of Windows XP Home Edition Sp2.

shouldnt the dsl router be connected directly to the wireless access point?

the second and third pc are connected by xover? are they on the same ip range for a start? i cant see why they would show limited/ no connectivity if they werent.

maybe print an ipconfig of the machines or tell us the addressing scheme to help you better

[dubsdj]

Have you tried a different crossover cable? Also check the network cards TCP-IP settings do they have a static ip address assigned. I think in your configuration you would need to have static ip addresses unless you have something acting as a DHCP server on your network.

So the secondary PC has 2 IPs, right ? One for WiFi the other one for the Xcable. I think you need to use ICS on that one to share to the 3rd PC, this is with DHCP and on an other range.

You are now using that 2nd PC as a "hub" which it is not. (cross my fingers hoping I didn't say something stupid )

Something I overlooked was the Network Bridge setting. I deleted the current Network bridge on the second computer and then recreated it, now everything seems to be working fine. Thanks for the help anyway.
