I can't ping router on same subnet using TCP/IP

[wncads]

I have a small network with two hubs and one router. All of the systems can communicate fine through the hubs but the router (actually a 56K LAN MODEM by 3com) will not allow anything not directly plugged into one of its four ports to see it or any computers past it???? I have another company with the same setup and they are having no problems. Everything appears to be the same and we are using the same identical subnet. IF I connect four systems to the router itself they can see each other, and ping, etc and have internet access... however if I use a crossover cable to connect to the hub I can see only things on the rpiters ports and seperately only things in the same hub ???? whats up any ideas??

Hi Keith - an obvious question. The cable, you sure it's a crossover? Mike

yes, I am getting a link on the router but not on the switch so to check the factory made crossover I rolled off some more cat 5 and made another crossover cable manually (I install Cat 5 as my job so I am doing that part correctly and the first crossover cable was actually a Belkin Factory Crossover Cable) .... I can't get a light on both the router and the switch. The link light only comes on on one... and I can't ping between the two boxes, I can only ping or get to the machines that are on the same side... any ideas anyone?? Keith Buchanan

I suppose that you are using the crosss over cable because you don't have a MDI/MDIX switch on your other hub.
Check using a straight cable also (maybe the hub has a port assigned for MDIX).
If there is not the above case, then take care that if the ports are auto and then there can be problems. Try to fix a speed.

should have replied back to let you guys know that I have the problem corrected. I was using a crossover to test against a faulty MDIX port on the hub, next morning took a new hub and set in place, it works like a charm, appears that the 3com hub was bad from the start.... thanks for the suggestions... now i will be much quicker to swap the hub when I know i have everything else as it should be and can't ping from one hub to the other...
