hub and router internet connection

[tmm49]

I have 2 computers & cabel modem connected to a router and the only way I could get the 3 computer with 100baseT to see the others was to go through a hub and connect to the router uplink. The first 2 units on the router can connect to the internet but the one on the hub won't.

Any suggestions?

thanks

Thanks for your response. Maybe you could direct me to the proper forum. Anyway my configuration is like this:

Intenet < router < 2 computers (With internet acces)
^
hub < 3rd computer (No internet access)

If I connect the 3rd computer direct to the router without the hub, it's port lights up as 100baseT and does not connect at all. 3rd computer can't map either of the other two computers drives. With the configuration above I can file and print share all three computers but the third has no internet connection. It seems like the router rufuses to assign the 3rd computer an IP address because when I set it to assign an address automatically, it finds some number that no way resemble the other 2 addresses.

Hope this helps. And thanks again for your help.

For what you are telling, its not a router problem, and it 's not a hub problem, now it might be a cable problem or a NIC problem or a driver/protocol problem.
Check if the IP adress that Third computer is receiving is starting 192.254.... subnet mask 255.255.0.0 ?
try changing the NIC card or exchanging the cables between one that is working and the one that is not.
