I deleted some codecs I had on here yesterday, and now when ever the computer is restarted I get a network cable unplugged message. If I unplug and the cord from the router and plug it back it it works fine untill I start up the computer again. I dont want to have to do that everytime! Anyone have any ideas?

Computer make and model number please?

Is your Ethernet intergrated into the motherboard or is this an add-on Ethernet adapter?

Also make and model number of your router.

Thanks in advance.

Bruce.

It is a custom computer. Running windows XP SP3. Intel Celeron E1500 2.2 GHz dual core and 3 GB of RAM. Ethernet is on the motherboard. Router is a Linksys WRT54G.
I have noticed that if I let the computer sit long enough it fixes itself. The wire from the router to the computer is custom made by me. I would think if I have one of the wires wrong it wouldn't work at all though.

Sounds to me like a speed and duplex issue.

Go to the properties of the NIC and check the advance properties. Look for speed and duplex. For speed. Set it to 10 Base. And for duplex set it to full.

In order to best diagnose, we would need to know what codecs you removed.

Also, if you are having such messages, you will need to try some of the following steps:

*Uninstall/Reinstall NIC drivers
*Try a new network cable
*System Restore to before the codec removal

If none of that works, then you may have done some damage to the OS that cannot be reversed. You can try running the SFC /SCANNOW from a command prompt, but you will need your Windows CD, preferrably with the current service pack you have installed.

If all else fails, you may have to backup and reinstall Windows.
