Dual boot Redhat Linux 9.0/Windows XP home NIC problem

I am having a problem with my NIC card in Windows XP home for my dual boot configuration. Everything works properly in Linux and my onboard BroadCom 4401 (BCM4401) NIC is properly recognized and configured upon startup and also shuts down upon shutdown and reboot. I am using the bcm4400 RPM downloaded from the Broadcom website [version 3.0.7-1].

The problem is that when I boot into Windows XP home the NIC card does not work. There are no lights on my hub or computer and Windows says: Network Cable Unplugged.

Lights are properly displayed on the hub when linux startup initialises eth0 and they disappear when shutdown disables eth0. Unfortunately, Windows XP doesn't seem to properly re-enable the NIC. I have try disabling and re-enabling the NIC in Windows XP and it still says: Network Cable Unplugged. I have also tried re-installing the NIC drivers in Windows XP with the same result.

I'm going to try just turning off my PC without using 'shutdown' as I am assuming that the Linux shutdown procedure is turning off the NIC...

***EDIT: When I just shut down the PC, the lights also dissappear on the hub and do NOT reappear when I boot into Windows XP.

Thanks in advance...

Well, it sort of Windows questtion rather than linux related, we had similar situation in our work network ( i'm a networking guy over there), the problem was that our cisco switches were rebooting sporadically. It drove us nuts since the spanning tree was recalculating every time the edges were going down and up. Problem solved though - and no Cisco had no idea about it. Our windows xp workstations were built with default NIC settings (all workstations are Compaq/HP), there is a setting in network card configuration to turn power management for NIC - we disabled it and problems with Cisco went away. Maybe this is sort of situation you are facing.

It is a windows question, but it only stopped working after I properly configured the card in Linux so I thought someone here could help...

1) I installed RedHat 9.0 in a dual boot configuration
2) I went into WinXP and configured TCP/IP to access my server and everything worked fine
3) I went into Linux and the network card was not found so I downloaded the bcm4400 drivers and installed them. Linux networking then worked fine.
4) The next time I went into WinXP, the 'Network Cable is Unplugged' error popped up.

Anyway, I downloaded the latest WinXP drivers from: URL=]BroadCom[/URL] and upgraded the drivers and it now seems to work fine!

Hello there,

I have exactly the same problem. After spending a considerable time installing the proper driver and configuring the internet on linux it works fine now. However when i boot up into windows it says that the network cable is unplugged when it is not. I thought i was going crazy until i saw this port

Could someone out there give me an idea of where i can start to solve this problem?

Thanks in advance.

I had exactly the same problem. However, once I installed the latest windows driver downloaded from broadcom -- problem resolved!

Hope this helps.
