>I think I know more about the problem (or other problems). Here is the list of the findings:
>
>1. I entered BIOS and see no changes from default. NIC is enabled just as it was before
>2. The Docking station is "broken". I mentioned that my cordless keyboard stopped working and that the sound no longer was going from the monitor speakers. This is the reason. The cordless keyboard transmitter was plugged into the Docking station. The cable to monitor speakers was plugged into the Audio Out in the Docking station. I also have an external hard drive plugged into a USB of the Docking station. None of the devices using the Docking station work. The only thing that Docking stations does send through to and from the computer is the video signal.
>So I suppose everything started with Docking stations going down.
>3. So, from this point, as much as hate not to have Docking station available (pain to connect everything every morning), I will start troubleshooting/testing without Docking stations.
>4. The Network connection still does not work (the wireless does work; this is how I am communication in UT now).

If the docking station appears "broken" don't use it at all, even if some components seem to be working. Also, while you are testing the wired connection, turn off or disable the wireless adapter. Many current laptops have a physical switch you can use to turn off the wireless radio. Or, you can disable the adapter in the control panel networking applet.

With the laptop not connected to the docking station, does your wired networking function at all?

One final test you should do is to try connecting with a "known good" connection. Select another computer in the office with a wired connection that is working properly, temporarily disconnect its network cable from the computer, and plug your laptop into that cable. That will be a known good cable connected to a known good port on the switch/hub. If that still doesn't work (you don't get LED indication of a connection and/or network activity) then you probably have hardware failure.

If your laptop is still under warranty you can call the manufacturer and ask them if there are any hardware diagnostics you can run to test the functionality of the network adapter. Even if not under warranty you may be able to find diagnostics on the maker's web site. Another possibility is Broadcom may offer diagnostics; they may even be built-in to the control panel applet installed on your system.
