NICs detected properly, but no network traffic

[justinault]

Strange NIC problem.

I have 2 different test systems that are giving the same issue.

Both of these systems run Core2Duo CPU's with Intel 945 chipset Asus motherboards.

One system has 2 Intel gig NIC's in it, the other has 2 10/100 NIC's in it (trendnet and d-link)

Both systems install fine and all 4 NICS are properly detected and configured. The problem is that no network traffic passes in or out of either system once up and running. Can't ping in or out of them.

I have a third test system using older hardware (P4 CPU with onboard NIC and add-in NIC) that works perfectly.

Any thoughts?

One more note: on the older test system that works, when connected locally to the terminal the mouse moves quick and smoothly. On both of the newer systems the mouse cursor moves slow and jerky. I don't know if it's related but I thought it strange that on newer, faster hardware that the mouse cursor would move so slow like that.

Thanks.

Update:

I can ping 127.0.0.1 from the local console, I forgot to try that.

I also tried to switch to bridge mode and still no traffic passes through.

Another update:

I installed Fedora 7 on the test machine with the Intel NICs in it and it still has the same network issues. Is something in the hardware not linux friendly but no apparent on the surface?

did you try different cables? hmmm, not sure on this one. Since it detected the NICs, it should work.

you might try this. Return the Untangle to factory default setting. Do the bridgemode, make sure it passes the connectivity test. Then test to see if the traffic is flowing through the Untangle.

justinault ... If I see slow and jerky response, I'm looking to see if there are heavy resource issues or conflicts. If you still have the Fedora 7 machine built, pop one NIC out and see if you can make contact with the outside world. Then, try the other one. I was just looking through other threads searching for "Asus" and found users "rcherry" and "pvcrisp" both had problems with these motherboards. You might also want to poke around and see if there are any BIOS settings you can change to see if you get different results.

I fixed the jerky mouse response (also noticed in Fedora 7) by using a USB->PS/2 adapter on the mouse and plugging it into the PS/2 port.

I also just pulled one of the Intel NICs out and it still won't communicate using the single NIC.

I think these 2 Asus motherboard just don't like Linux for some reason. They are models P5GC-VM and P5L-MX.

What other mATX board would you suggest that I buy to run Untangle with a Core2Duo CPU and 2GB of RAM?

Update:

Networking works fine if I install Ubuntu Desktop 7.10 x86
