It seems that the motherboard N68C-GS4 FX integrated Atheros AR8171 Gigabit LAN card isn't capable of being Gigabit !!! I have only managed to get it running in fast ethernet mode (100 instead of 1000). I thought perhaps it is a software issue (you don't get an option in the driver to force Gigabit speed) and tried every possible combination with no success (tried every revision of driver possible various OS-es installed different cables bootable CDs etc). It seems that the problem exists also in a similar motherboard with a different LAN Gigabit card (N68C-GS FX) according to people in other forums. Maybe the same Nvidia chipset doesn't get along with integrated LAN cards that aren't Nvidia on similar motherboards ? Few of the latest BIOS revisions on this motherboard seem to be fixing LAN card problems. Well when is it going to get fixed finally ? I thought I could fix my problems by switching my new motherboard with the only other similar (compatible) motherboard but I don't want to risk getting into same problems again. Don't get me wrong the motherboard works great and with no problems just that glitch is getting on my nerves as I do A LOT of networking stuff and fast ethernet speeds just don't cut it. I have sent an official complaint to the support department already but they aren't answering. Anybody got a similar problem and managed to solve it somehow ?

you are certain you have an Ethernet cable capable of 1Gbps speeds and you are connecting to another device capable of 1Gbps speeds, and that at no point between or at either end of the connection either isn't set for, or isn't capable of 1Gbps connections?

Every single point and thing you use has to be capable or the controller will fall back to a slower connection mode. Considering you can still get Ethernet cables capable of only 100Mbps connections, and a LOT of devices only have, or mix in ports, that only support 100Mbps. That is the more likely the case. Have you tested something that does support 1Gbps and works at 1Gbps in the same location as the motherboard? How did you discount every other device on your network being the source of the problem?

Doesn't matter what other people post on the internet, you need to discount the other factors yourself. it could be all the other internet posts are wrong, and the issue is with those peoples setups.

If you did discount everything else yourself, then disregard above. I don't have the other motherboard in question, and only someone who owns that model could tell you for certain, and even then, maybe this is just a glitch on some of the units and it may not effect all units. If the updated firmware doesn't help, not much else you can do besides switch to another model, or get a replacement, and pray.

If you were really risky, see if you can get a different driver directly from Atheros, or from somewhere else for the same type of chip. Maybe the ones asrock provides are the buggy ones and there is a different version somewhere else that work.

I have solved the case myself. I have successfuly RMA'd my MBO to the authorised vendor and got a substitute new MBO. I have tested the new MBO and everything works OK. The first new MBO was faulty.
