Nforce3 Network problem.

Liqourice · Oct 22, 2007, 09:04 AM

I'm having a strange problem with my built-in nforce3 NIC.

On my second computer I get to use the full 14 Mbit downstream and 1 Mbit upstream that I have on my connection. (VIA Chipset on that one but using a PCI RTL8139)

On this computer I only get about 6.5 Mbit downstream and 0.85 upstream on both windows installations.

The reason I am sure it's a driver issue is that when I run Ubuntu 7.10 on the same computer using the same NIC I again get the full 14/1 Mbit.

I can't find any newer driver from nvidia then the one I have installad and that came with the driver package on the motherboard CD.

Does anyone have an clue as to what I can do?

Try fiddling with the MTU's.

The new driver would be in the nForce 3 chipset driver package, not as a separate driver I think (same way on my NF2 board), so you might try that.

There's only one version of the NF3 chipset driver package avaliable, I've got the same on the motherboard cd as I can download from nvidia. So, no other driver avaliable than the one I have.

Tried to change MTU and some other settings but to no avail. I ended up robbing the other computer of the pci nic and use the builtin on that instead. Now I run with full speed on this comp as well.

Cannot find the reason why the nf3 nic doesn't work properly. Sent a support question to nvidia but no answer.

Does having I/O tasks (disk transfers and such) going affect the speed?

Does Windows Update offer a driver for the NF3 network adapter?

Negative on both.

Well, I have disabled it for now and I'm using a PCI NIC. Probably better in the long run anyway.

It's been a long time but I remember disabling the Offload Transmit TCP Checksum option in the network adapter settings improved things quite a bit. Might be worth a shot and you can enable it again if it doesn't help.

I've tried just about every setting without success. But, I just might try it again.

Sorry to hear

I only remember that one setting because it would cause erratic transfers and crazy disconnects when gaming online. I know WoW definitely didn't play well with it.

Edit- Make sure you restart when changing settings

I always do.

my nforce2 has a 'utilize for cpu efficiency/thoroughput' option, & have it set to thoroughput of course

there's also an option to detect or force 100mbit fullduplex/half/someothers/etc

is it into a router or modem?

Liqourice · Dec 5, 2007, 01:49 PM

I've tested all those settings without success. The only thing I managed to do was to get an even worse result changing them.

It's into a router but I don't see that it should make a difference when all other nic's perform perfectly and this one does in linux....
