network cable is unpluged while network is plugged in.

Question

Hi,

why error: network cable is unpluged while network is plugged in correctly?

I have insprion 5150, I had no problem with my Local Area Network and Bradcom 440x 10/100 during the period of time that I was using it.

2 weeks ago after I update my Microsoft Windows XP, and it installed Microsoft Dot Net 2.0 and few other security updates, and restart my computer, my Local Area Network starts giving my network cable unplugged error every 30 minutes.

Events in system events of computer manager:

1.

11:36:42 PM

Broadcom 440x 10/100 Integrated Controller: The network link is down. Check to make sure the network cable is properly connected.

2.

11:36:45 PM

Broadcom 440x 10/100 Integrated Controller: Network controller configured for 100Mb full-duplex link.

3.

The system detected that network adapter Broadcom 440x 10/100 Integrated Controller was connected to the network, and has initiated normal operation over the network adapter.

Thanks for your Attention,

In this case I would try to disable the security options you installed for testing purposes. then roll back the drivers for the network card. you may even uninstall the software you put in. Get the system back to the way it was before the upgrades and see that the network is back on line. then add the upgrades one by one . One of them has probably diabled the networking through the drivers for the card or the protocols.
good luck
