Ethernet port running at 10Mbps

Thanks for all the help everyone. By the way, I did try it in Ubuntu 10.04 and there I could get NO connection. wireless or auto eth0. But now everything seems to be working fine. Thanks guys.

If eth0 wasn't coming up under Ubuntu then it definitely sounds like flaky hardware, I'd have a spare card (like that Intel PCI-E one) on standby.

Well, it seems to have worked itself out. Although I will have a spare in chance this happens again. Thanks again guys.

Anyway, the OP's problem seems to be either hardware or software. I am not going to repeat what others have mentioned. I have seen my fair share of funky network issues. It doesn't hurt to explore all avenues to determine the issue at hand.

Well, here is what I did. Uninstalled old drivers. Installed new ones, no luck. Tried most recent drivers from Gigabyte and Realtek and that didn't work. Then right after that, my NIC continued to stay stagnant as "network cable unplugged" for about an hour worth of me trouble shooting. I tried band new cables for both the modem and router, still no luck. I took apart the main parts of my pc, unplugged all the cables, cleared the cmos and discharged the caps. I then proceded to install the driver from the Installation cd from which I got with my mobo from Gigabyte. It halted at "installing driver.' (Which I had done perviously in the night) I restarted my computer and seriously eveything is working fine now. Anyone have any idea what would have caused an issue like this. I don't have any other OS's installed on this drive. I haven't added any new significant software, aside from an update to chrome. Just couldn't figure it out. If anyone else has come across this problem and found a solution without spending any bones, i'd love to hear what you had to go through. Thanks for all the help everyone and i'm glad i finally have my netz back.

If it happens again, try booting into a Linux LiveCD and doing "ethtool eth0". I assume that you only have one NIC in the system. If you have two, you might need to do "ethtool eth1" depending on how the LiveCD configures the interfaces. Not all Live CDs have ethtool installed, so my suggestion is to use System Rescue CD:

If it is 10Mbps under Windows, 1Gbps under the Live CD and then still 10Mbps under Windows after you reboot into Windows, then it is likely a Windows problem.

That is an ad hominem attack.

With imprecise grammar, no less. Tsk tsk, Krogoth.

Mod hat on
OK, everything has been just a bit of good natured bantering back and forth so far, but let's try and keep clear of Forum Rule 2.
Mod hat off

I get the same issue on my dual gigabit ports on Gigabyte P55A-UD4P board. The only solution I found that works is to turn off my PC AND switch off the PSU or unplug from the wall then start the machine again, and then it works again full speed.
It has nothing to do with drivers or OS since I can check if it's working correctly or not from BIOS.

I had the same problem with one of the ports on my gigabyte X48-DQ6 board...had nothing but issues with one of my ports running at extremely slow speeds. Multiple driver changes and connection repairs did nothing for me. I finally ended up removing both from device manager and rebooting into my bios and turning both NICs off. Then I booted into windows, shut down again and went into the bios and turned them both back on. Once back into windows I reinstalled the most recent drivers, and both worked fine. Still working fine a year later, so it seemed to repair my issue.
