[Solved] Ga ep45 ud3p MB Lan problems

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 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.

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:

Ok
I just spent 12 hours on the LAN issue. Neither one worked. I updated to the newest MS drivers, stood on one foot, howeld at the moon while naked, jumped around 3 times and said there's no place like home. So I did everytihg including refomrating and reloading XP.

Just as I was about to "kick the cat" at 12.09 midnight. I saw the suggestion to load failsafe. Well hell, it worked. Not sure why yet, went into Hardware propereties and I'll be damned all the hardware was showing up with no yellow fingers, i mean exlimation points, flippping me off.

So try it...... I just hope the issue is completely gone.. and I am setting a restore point as we speak.

Hope this helps.

XP service pack II
Asus PCIe
e7500
4 gigs Corsair

nothing else.

Load FailSave Defults worked for me, maybe it was the 64bit setting that made it fail but anyway it works now, tank you!

None of this worked for me. Then I noticed that the McAfee Antivirus was on the computer without the update. I uninstalled it and that was all it took. Try uninstalling your firewall or antivirus software. You can always put it back later.
