Just recently ''upgraded''' my dinosaur PC with a new (to me) ''used'' EVGA 680i mobo I bought off of evilBay. So far.. almost everything is performing correctly save for one problem. I can't get either of the LAN ports to work on it. I have a dual-boot system (XP Home x86 and XP HP x64) and although the drivers WILL install in both OS's and they both do show up in the device manager.. I can't connect to the internet in either of them. I bought an add-on NIC card and it's performing fine; plus my old ECS mobo worked just fine with it's onboard NIC hooked up to directly to my cable modem.
When I enable the two ports in BIOS and install an OS.. the drivers for them install just fine whereafter they also show up in the Device Manager and ''appear'' to be functioning correctly, but when I plug the active network cable into either one of them.. they appear to sense that as well.. then go through their ''searching'' routine.. and eventually come up with a ''NO internet connection found'' type of dialog/error.
I've tried MANY things to diagnose this:
1. Changing out for another cable.
2. Tried both ports, and finagling with various settings in the Nvidia NAM utility.
3. Tried disabling IVP6.
4. Cleared CMOS.
5. Clicking ''repair'' and letting it go through it's thing.. whereupon it usually ends up saying some kind of problem detecting the default gateway of the modem.
6. Resetting the modem and renewing a new IP address (which is successful on the modem's end).
The list goes on and on..
I HAVE scoured the forum here, and the ''net'' for a solution. Keep in mind this is happening in BOTH operating systems with the SAME kind of end result (although some of the dialogs and messages differ). One thing I can't do is try the ports for other functionality. Actually.. I suppose I could try hooking up my XBox 360 directly to my PC and see if they could communicate through Media Center or something.. but my 360 isn't hooked up to the internet and I wouldn't have a clue as to what to set up or look for.
I guess most indications point to a hardware failure of the controller itself since neither port works. Are both of them controlled by the same chip? Probably so.
Also bear in mind that this is not the ever notorious ''connection drops out'' issue that many suffer in W7 since I can't even get the ports functional and they act the same in XP. Just like enabling trim in W7 with this board by installing the default MS drivers for the storage adapter.. the ONE thing I haven't tried is picking the MS OS generic ones for the NICs (a cure for the W7 drop-out issue). I haven't tried that in either OS (just heard about it tonight) but I don't hold out much hope.
Here are links to two screen captures of some settings in both XP and W7. Since I'm a newb here I can't yet insert hyperlinks.. sorry.
Sheez.. apparently I can't even type in a web address!.. ludicrous!
I'm open to any suggestions. I know the motherboard is old.. but so far I'm loving it compared to my older one. I'm using a Q6600 and two EVGA 8800 GTs in SLI that a friend gave me. I've tried oc'ing the CPU but it runs too hot and I think the PSU is too cheap for it. The 8800s are already the 675 stock oc'ed models. I'm running 4X2GB of GSKILL 666 RAM (just fine I might add) and haven't tried oc'ing them since I can't seem to get the CPU stable.
Thanks to all for your time and attention.
BTW.. I guess it's obvious.. but I have been using the last set of nForce drivers on this. Also.. I HAVE tried various BIOs versions as well. I'm currently on P28 because until I get the proper bridge I have to use my old short ASUS flex-bridge and have to use PCIex slots 1 and 2.
