Ethernet Controller-media disconnected

By KeithWilliamsATL ·
I have a Broadcom 4400 Controller for my network adapter for Ethernet. I'm getting an error message stating "media disconnected". Cable is good and the router is good. I have tried the Winfix program and media still disconnected. System is a Dell running Windows XP. I even tried hooking a USB wireless adapter and no change. Can anyone give me a suggestion.

First thing to do Keith is to edit your post

and remove your e-mail address unless you like SPAM. You can enable Peer Mail. Try updating your Broadcom Drivers. If you are unable to do that at the moment try this.

To direct Windows to automatically detect and install network adapters for you, follow these steps:

1. Right-click My Computer, and then click Properties.

2. Click the Hardware tab, and then click Device Manager.

3. To see a list of installed network adapters, expand Network adapter(s). Click to locate the network adapter, and then click Uninstall.

4. Restart the computer, and then let the system automatically detect and install the network adapter drivers.

Windows XP
Click Start and go to Control Panel.
Click on <i>Network and/or Internet Connections</i> depending on your view.
Click <i>Network Connections.</i>
Right click on <i>Local Area Connection</i> and choose <i>Properties.</i> If this icon does not appear, then your network card is not being <i>detected</i> by Windows. This icon should appear automatically if your card is detected. If its not being detected try reinstalling the Network Drivers.
Under the <i>Connect Using</i> label, make sure that your network card is properly listed.
If you look below you will see a drop down box, there will be a list of all installed/available protocols for your network card. Scroll down and find the "Internet TCP/IP".
Highlight this entry and click on the Properties button below the list. If you have pre-configured values in this window, you may want to write down the information for future reference. Then, make sure that the option "Obtain IP address automatically" has been selected. Also, make sure that the setting "Obtain DNS Server Address Automatically" is set.
When these two properties are set, go ahead and click the "OK" button to close the Properties panel and click "OK" again to close the control panel. Windows may or may not ask you to restart.
Click on the "START" button and click on "RUN".
Type in "cmd" and click "OK".
At the command prompt type <i>ipconfig /all</i> and press ENTER. The IP Address should be in the format "". If your IP Address starts with "169.254", your configuration is not correct or you are not plugged into the Unit correctly.

Try the ping command.
At the command prompt type ping and press Enter. If it doesn't then there's a fault with the Network card and it will have to be replaced.

Type netsh winsock reset at the command prompt, and then press ENTER.
Let us know how you get on.

Worked for me on a Win 7 laptop

Jackie: Thanks. Was trying to deal with same problem for a week. Laptop is now back online. Any idea about the likely source of the problem? Had just upgraded from Vista to Win 7 a couple of weeks ago, and was recently playing with VMWare player running Fedora OS. Fedora couldn't connect to the Internet, which is about the same time I realized that neither my wired nor wireless connection were working, with ipconfig showing 'media disconnected.' Jim S.

Well for starters Keith edit you post and remove your

E-Mail Address ASAP to prevent your In Box getting flooded with Spam. You should never provide your E-Mail Address on a Public Forum as there are lots of nasty Bots crawling the Net looking for these to send to their masters so they have New Meat for their junk.

Secondly fitting a USB WiFi Device will do nothing to rectify a dead LAN Connection it will do nothing unless you configure a WiFi Connection to work through it and switch connections.

Now assuming that you only have one Ethernet Connection on your computer and you are constantly seeing a Cable Unplugged Message no matter if the CAT5 Cable is plugged in or not and that you have tested the actual Cable on a different computer or with a cable tester you need to look inside where it plugs into the computer. There could be something in there preventing a connection being made or the Socket could be just broken.

If however you get a different message when you unplug the CAT5 cable to when it is actually plugged in then the Windows Software that controls the Ethernet has been corrupted by something that has been added to this computer. You can start off by looking in Device Manager which can be accessed by right clicking on My Computer then left clicking on Proprieties in the drop down list, then the Hardware Tab on the new window that pens then Hardware and look for any Yellow Circles with a Black Exclamation Mark through them. This indicates either no drivers installed or corrupt drivers. If there is nothing shown there close it down and then open the Control Panel from the Start Show All Control Panel left click on Classic View and then left click on Network Connections and left click on Local Area Connection. If there is more than 1 entry here post back which what is actually in the Network Connections Window.

If there is the one entry left click on it and then select the Support Tab and Repair. If it doesn't solve the problem post back with what happened.
