Windows 7: The wired network adapter is experiencing problems

The wired network adapter is experiencing problems

Hello! I searched for this but was unable to find this issue (please help me refine my search if I am incorrect).

Backstory: About a month ago my PC lost connectivity with my router. It is connected via Ethernet cable to the Linksys WRT54G. All other wireless devices (both iPhones, PS3, Wii, the wife's Macbook, and my old HP laptop) have not lost connectivity.

Attempted fixes:
Confirmed Ethernet cables not suspect, bought and installed a new Dynex NIC to check and it had the same issue. Green lights on both cards and router were lit correctly. Wife's Macbook connects to Ethernet port on router with no problems (my HP laptop did not connect via ethernet but I put that down to the laptop being old.)

The PC's Network diagnostics just tells me "there might be a problem with the driver with the Local Area Connection adapter". Device Manager shows the Network adapter (Intel(R) 82578DC Gigabit Network Connection) to be running properly.

I went searching for a driver and on Intel's site found and downloaded PROWinx64.exe to my laptop and transferred it to the PC via USB flashdrive. Installed it and have new features on it's properties in Device Manager but still on connection. Uninstalled and then installed an older version of PROWinx64.exe form Intel's website and same problem.

ipconfig /all shows Media Disconnected

Thank you for any help or new directions to go.

Can you connect to Linksys using:


Is you IP address and DNS automatically assigned?

I long ago changed the IP address to to not conflict with the modem and the laptop and Macbook are able to view and access the browser page for the router but the PC just says "cannot display the webpage".

DHCP on router is on Auto Configuration.

When the PCI NIC didn't work I got on chat help from Linksys and they said it could be the ports went bad but the wireless was still working. I tried to HP laptop by ethernet and it didn't connect so I went out and got a Netgear N300. Right before I opened it I tried the Macbook by ethernet to see if the laptop just had a problem and it worked just fine on the ethernet. I'd love to open the Netgear N to upgrade from the Linksys Wireless G but want to solve this issue first.

Just thought I'd post the current status of my problem. After completely ruling out my router as the issue I took it to a friend who is in the tech field. He was unable to find out what the problem was either. He said we were not going to be paying for service when my PC is under warranty but we could not find a number to call. His solution was to call the pay for support line and ask for the warranty service number which got us to the correct service line. The tech ran us through a few more checks and ended up saying that the last thing to try was a restore to factory settings. I took my PC home, saved what I needed to, and did the restore. It actually worked! I'm back up and running and things seem to be fixed for now.

Thanks for the help!
