Thanks for the link, however the only driver that I think is the right one keeps saying "The operating system is not supported. The software will not be installed."

So I seem to have a problem.

 ukAdamR,

Try running Finding System Information. At the bottom you'll see your network adapters. Post the network adapters here along with the make and model of your computer and operating system.

Hello, I'm having the same problem. (Code 10 - cannot start) on a Broadcom NetXtreme Gigabit Ethernet Controller, BCM5761E. I've tried the drivers from the Broadcom site (b57nd60a) and from Dell.com (file R239885.exe), same result, cannot start. I'm on a Dell Precision M6400 Laptop running Windows Vista 64. I haven't reinstalled Windows, it used to work fine, I don't know what happened.

Here is the device instance path: PCI\VEN_14E4&DEV_1680&SUBSYS_168014E4&REV_10\4&15B2C2F&0&00E5

The problem is intermittent, sometimes it works, most of the time it doesn't. I'm currently using wireless to access the internet. I communicated briefly with Broadcom support, but they stopped responding to me. They told me to run the diagnostic tool you can download from the bottom of this page:

http://www.broadcom.com/support/ethernet_nic/netxtreme_desktop.php

Here is the result that I got:

----

Error detected at device 0 (PCI slot 09:00:00)
Revision: 14.13
Unit under test: NIC
Module: IRQ Test
Test Name: IRQ Check
Error #18
Cannot gain access to flash, SwArbit: 3100
Msg: Failed reading NVRAM at 0x0000
----

I sent this result to them, and got no reply. I'd appreciate any help that anyone here can provide.

 marklm2,

Did you try using these drivers?

Broadcom BCM5784M LAN or better known as Broadcom Netlink Gigibit Ethernet (64-bit drivers)

Rick

I just tried installing those drivers, and I'm getting the same result. My guess is that this might not be a driver issue.

 marklm2,

Reinstall the operating system recently?

Try system restore and go back to when this worked?

Restart the computer and Press F2 on startup. Look and make sure everthing looks correct in the bios.

Start, control panel, device manager, network, right click on the adapter and make sure it's enabled there. If so, then try deleting it, then restart your computer. Windows should install it and correct the issue if there was a problem. Make a system restore point first in case this doesn't work.

Solved:

I have a Latitude 5420 and problems with Broadcom Netxtreme Gigabit from the beginning (code 10 -  malfunction). I tried everything, but only changing in BIOS at Integrated NIC from enabled to "enabled w/pxe" worked.
