Update the driver

You may be prompted to provide the path of the driver. Windows may have the driver built-in, or may still have the driver files installed from the last time that you set up the device. However, sometimes, it will open the New Hardware Wizard which may ask for the driver. If you are asked for the driver and you do not have it, you can try to download the latest driver from the hardware vendor’s Web site.

In the device Properties dialog box, click the Driver tab, and then click Update Driver to start the Hardware Update Wizard. Follow the instructions to update the driver.

What virus program and firewall are you using?

Hi Rick.  

Our 460MT also does the same thing - Windows does not think there is a Network card at all so there is no driver to update.  Reboot 3-4 (sometimes 5 times) and it's eventually found, and then works normally.

System information as below. (once the NIC was found!)

We're using the Trend Micro that came with the machine.

Thanks in advance!

SFrog,

I don't see a wireless adapter in the log. Places to look to see if the Connection is enabled If you have a wireless adpater, does it show in the device manager? If yes, click on advanced and see if it has antenna diversity. Some adapters have it and some don't. If your adapter has it, then change the antenna diversity from auto to aux.

Start, control panel, network and sharing center. Click on your network, then click on properties.

Look for TCP/IPv4 and TCP/Ipv6 mand click on properties for each. Make your settings match mine.

Jason,

See if these drivers work.

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

<ADMIN NOTE: Broken link has been removed / replaced from this post by Dell>

You might have to install them in the Vista Compatibility mode

Rick

Hi Rick.

Thanks for the reply.

The issue isn't a wireless networking issue, it's the wired network adapter that isn't found.

Thanks.

Jason.

The file version you are suggesting is from 2008, the most current version from Broadcom site is 14.8.2.0, from 7/12/2011, which still exhibits the same behavior.  We are running Kaspersky AV v6.0.4.  Considering SFrog is running the Trend Micro AV may not be the culprit.

Hi,

I have had similar issues, the issue is actually caused by a corrupt Windows Update installation, if you are lucky a System restore to an earlier point i.e., before the update occured would resolve this.

In my case i had to re-install the OS.

I would suggest re-installing OS if you have already tried the following

- Update / Re-install network drivers.

- System Restore.

Trust me a factory re-install is faster than trying to get to the bottom of this, in your case with 10 systems Dell Datasafe is the only software to the rescue.

I didn't mention it, but this system went offline at 5:45 on Sunday.  It appears to be the same time frame as your problem.
