"Network Cable Unplugged" But it isent

Freedom · 6 Apr 2008 at 03:57

Hi there.

I turned my computer on this morning to find that there was no internet connectivity.

I checked the network settings and it says that the network cable is unplugged, which it isent.

Ive tried the cable in different ports on the router. Ive checked the cable on this laptop to make sure it was working, Ive uninstalled the network card and reinstalled, but with no luck. Ive updated the driver, but still no luck.

Im at a loss about what could be causing this.

Its an Onboard Realtec using windows vista 64bit.

Its been working for the past 5 months and just suddenly stopped working.

Have you tried another stand alone card just to make sure it's not a fault with the O/B one. As unusual as it may seem i have had an O/B network card die before now.

Unless there is a dodgy contact on the plug/mobo it sounds dead. You have tried everything anyone else would do.

What Motherboard is it ??

I have an asus motherboard and apparently there is a bug where the onboard lan's go into sleep mode and wont wake from it.

The soloution is to power pc down , remove power lead , and press start button and reset button and hold them down for 30 seconds , then power back up and everything is ok.

Mine has done this in the past and as silly as it seems it actually works , apparently it discharges the capacitors on the motherboard and resets the wake on lan / sleep on lan feature on the motherboard.

If you aint got an Asus board , dont suppose there is no harm in tryin....

Try this

1. Unistall the network card from device manager
2. Go into BIOS and disable the onboard network
3. Boot fully into Windows
4. Shutdown , not restart
5. Turn PC back on, reenable onboard network
6. Book to windows, let it redetect and install the network card.

Make sure the network speed is set to 100mbit in the network card properties.

Have you recently installed a Window Update? This used to happens on my mobo and it was a sodding update that was causing the problem. I used system restore to go back to a previous save point.

I don't think it's dead TBH. What happened in my case was that a Windows Update installed a NIC update, this update seemed to hide my currently installed NIC which was still working and sourcing an IP address from my router and installed a new NIC but as the old NIC was still active but hidden the newly installed NIC wouldn't work properly.

The first time round I removed all references to the old/new NIC in the registry and deleted the visbile NIC in Device Manager, then rebooted, this fixed it but the Windows Update went in again the next day and it screwed it up again. So this time I did a System Restore and got the latest drivers off the Marvel site, installed the latest drivers and alls been fine.

Sorry for the Late Reply Guys,

I removed the driver and uninstaled the Nic, and I disabled the Onboard Nic in the Bios, I took the Power cable out and left if off for 30 seconds.

Powered the computer up, Re-Enabled it through the Bios, Let windows Install the driver and it worked.

Thanks for the help Guys.
