Hello. I have a very frustrating and unusual problem. When I connect my power cord to my laptop, I lose connection with the network and internet. Zap. Gone. If I unplug my power cord, TADA, it comes back! Oddly enough, my wireless network card is not affected by this madness - only my wired LAN card. Any CLUE as to what could be causing this unusual problem?

My gratitude,

Jason

I should probably mention that this problem began after upgrading to Windows 7. That might be a slightly important clue.

Downloading drivers for Intel® 82567LM now. Perfect timing as I have only a few minutes of battery left. :huh: I'll be back shortly after I uninstall old, reinstall new, reboot.

Thanks and see ya.

Ok, updating the driver from Intel caused the NIC to stop working alltogether. So, I rolled things back and I'm currently DLing the driver from Dell. Any other suggestions before I try this? Be back in a bit.

Tried the latest driver from Intel - killed the NIC, even with it unplugged.

Installed the latest driver from Dell, but I think it's the same one I had, so nothing different.

So, back to square 1.

Weee!

Not sure about that. I can check with the purchaser. Are you thinking I should send it in for repair?
