My motherboard always boots into a 100mbit

Hi, I have an ASUS p5n32-e SLI plus using 1002 bios, so it's compatible with my e8400.

I wasn't paying too close attention before, but everytime I reboot my connection is set at 100mbit, I have to unplug and plug the cord in a couple of times in order to get gigabit. Disabling and re-enabling my connection in win xp 32bit is unsuccessful, but I only tried it about 5 times in a row because it takes longer than just physically re-plugging it in, and that only takes one or two tries.

I have tried with two brand new cat5e cables, and my roommate's cat5e cable that boots up to gigabit every time for him.

I have also tried with both adapters built into the motherboard.

It's not a serious problem but it's kind of annoying.
 
Sounds like auto-negotiation isn't working right. You have it plugged into a gigabit switch, I assume?
 
Markbnj, yup it's plugged into a gigabit switch. Netgear gs608.

rickeo i usually rotate ports every time i plug and unplug the cord. It could be a driver issue but I think I'm using the newest ones available from ASUS, and I never really had luck getting the ethernet drivers to work directly from nvidia. I could give that a try. However, it usually looks like it gets a 100mbit connection before windows even begins to boot. If it's 100mbit, I connect with an orange light, and at 1gbit it's a green light. The yellow light comes on seconds after I power up my computer.
 
keep it unplugged during boot, then plug in once in windows, see what happens then. Not sure what to do next as Im alittle drunk right now, but you can figure that out...
 
This is frequently an indication of a cabling problem.

Check the cable for kinks, crushes, stretches, twists, sharp bends, damaged sheath, sheath stretched out of the connector, etc.

If these are handmade cables, try commercially made "store bought" cables.

Also check the path of the cable to clear them of proximity to noise sources (AC, Motors, plasma TVs, CFL bulbs ...)

Gig uses all four pair for Tx & Rx, in both directions, at the same time. Your cables must be in good condition, and they must be relatively noise free.

Good Luck

I also suspected cables, so you can see in my first post I said I tried two brand new cables. These were store bought, not made by me, because the ones I was using previously I made and they were giving me this problem.

Also, like I said, my roommates store bought cable works perfectly for him every time.

The only sources of noise that are near my cable are also near his and they don't seem to bother his gigabit.

I hope I don't have to RMA my motherboard.
