LAN(s) drop off indiscriminately, constantly reinstalling NIC in MB

Hey and Good day:

Ever Since cranking up my newly built IP35 Pro Abit board with Dual Gig LANS I have been having mind boggling connectivity issues.

ie. First installation, took multiple removal of Realtek RTL8169/8110 Gig Nic from the device manager and reinstalling them to the MB using the MB setup disc, and finally Lan 1 connected and worked for a couple days..

Came in and saw the light on the cable modem for the LAN connection is not flashing or lit. Connection shows cable unplugged. So I reset the modem, re-plug in the cable restart the computer and nothing.. So I try to repair the connection. Windows says couldn't repair because it could not aquire an address.. So that time I thought well I will plug it into the other Lan on the MB and to my surprise it connected immediately and so I walked away, Hey it works.

Worked fine for two days. Walk in and see the modem light no flash/no nothing. Connections says cable unplugged. First thing I did was plug it into the other Lan. nothing this time,, no nothing..

So I refreshed the Drivers for both Nics in device manager. No help. So I uninstalled them and reinstalled them. No help. So I removed them and went into the CMOS and disabled them and started up the machine fresh and reinstalled the LANS using thd MB disc. In this process is said Realtek etc. needs driver. So I point it to the driver(latest fresh download of recomended driver-same as used before) and viola.. LAN 1 that first worked but stopped working which caused me to use LAN 2 was now working. BUT LAN 2 would not function.. So I figure, hey LAN 1 works (which by the way because of multiple uninstals and re-installs are now numbered Lan 5 and 6).

That worked for a couple days. Today I come in and find the modem light off and same problem but the connection now showing limited or no connectivity instead of the standard one I got (cable unplugged).. I tried refreshing the driver, removing it and reinstalling it. I tried pluggin into LAN 2 and did not work..

So I go through the whole process again, remove from system, disable from MB Cmos, reinstall on clean boot, and I get one connection showing limited connecitivy and the light on the modem flashing but for the life of me could not get it to connect. So I tried Repair, same thing, could not aquire address..

So I then figure well I will try LAN 2, so I plug into that one and sure enough it connects and allows me to send this HELP message to you..

any idea's? what in the world is going on.. I would sure like to not have to go through this every couple days. LOL

I appreciate your time, consideration and help..

thank you very much

Hey and good day stranger.. I guess we are all alone in this issue eh?

Update on mine. It seems as though I am having the problem much less often now. In fact about 8 or 9 days now without a problem. The last time it happened, I merely put in my motherboard disc and selected drivers/Lan and realtek for xp and it had a repair option available when I selected to install the driver.. I selected repair and ran it and for the first time doing it this way without stripping the system of every and all things relating to the realtek NIC connector that it actually fixed it first time..

Both Lans worked after doing that, and the Lan I choose to use, Lan 1 I believe is, as I said still up and running.. I don't know if Lan 2 is still functional, but at this point no reason to waste time checking it being Lan 1 is working fine.. why fix what aint broke eh? or don't know if its broke..lol

what is your situation now??

hope all is great..
