I have a new build with a ga ep45 ud3p MB and I can't get the onboard lan to work correctly. I can connect but I have to repair the connection all the time. My download are also very slow, I am using XP and have 4g of Ram.

Any ideas?

Do any Network Adaptor problems show up in Device Manager? Have you checked for any software updates?

Did you install the chipset and lan drivers from your motherboard?

I've hard problems where the network doesn't work to well without the chipset drivers.

Also check bios and make sure the lan is set to full duplex. You could also try loading the failsafe defaults if you want.

I've got the same problem. I have literally tried about everything including updated bios, drivers.
Re-installed windows xp too, to no avail.
Got a tech Query into Gigabyte, hopefully they will reply.

Make sure C4/C4e is turned off in bios - this causes intermittent cutouts on ethernet if no significant activity is occuring on the ethernet/PCI bus.

I really thought it was my gigabyte board, but when I replaced my dlink 4300 gaming router with a
D-link 655 router, all my problems went away. Picked up my transfer speed as a bonus.
Can't recommend this router enough.

I have the same board.
Not had any problems.

However there is a 'LAN Power Saving' setting in the BIOS, make sure this is disabled (it turns off the network clock when idle to save power, waste of time and could be causing your issues).

By default, the C4E as above will be turned off, only C1 is enabled by default.

But as above, make sure you're running the latest drives in Windows. I didn't have to worry because I used 7, and the built in drivers are great, but with XP you may need the latest Gigabyte drivers.

I'm using the same motherboard, and I just loaded Windows 7 a few weeks ago. I haven't been able to get my ethernet to work at all either (I have a separate wireless card that works). I've downloaded the newest drivers (Windows also recognizes them as up to date), but there is an error with everything I do. Windows can't figure out what it is to troubleshoot or even give me any kind of info. I'll double check my BIOS settings, but I had no problem with my mobo on XP.

MS has 'dished out' a broken driver update for the RealTek LAN chip recently. Load 7006.1023 driver from RealTek here:

There is also a comprehesive diagnostic there, on the same page, and is damned handy - but - you want to be careful with it; I'd recommend setting a restore point before installing, so you can get a complete uninstall - it puts in ringzero components you really don't want 'lingering' in your machine afterwards - and using something like RevoUninstall doesn't hurt either:

Weird, I never had LAN driver issues with 7 on the EP45.
Must've gotten lucky. I am having sound issues though ("Audio device was disconnected" in Windows Media Player, have to reopen files occasionally).
