Hi... On the web, and youTube, this looks like a common problem.. but the suggested fixes are a crap shoot .. not much tutorial for determining a cause.. just some work around that "might" fix it..
This is a Dell E6410 ATG, re-imaged using Windows 7 Pro. .. The Dell support for downloading drivers (in the correct order) is still a bit imprecise. Using "Device Manager" and the Network Adapters group.. some indication of network adapters was originally found.
When connecting by cable via ethernet connection, A "Windows detect IP address conflict" and "Unidentified Network" park bench icon, was indicated between the computer and world icons in Network and Sharing Center window.
Wireless/WiFi is working fine .. I get on the internet and there's a nice "Home" icon in the center.
One of the network devices was "Broadcom USH" .. my best effort was to load Intel® 82577LM Gigabit Network Connection driver .. which gives "this device is working properly" in properties.
The interesting thing is.. when you click on the icon in the network icon in the lower right corner (tool bar?), you get the typical list of available connections.. "currently Connected to", Dial-up and VPN & Wireless Network Connections… why does it list Broadband Connection as an option… ? That's the one that doesn't work.
I can plug in the ethernet cable on 3 other Windows 7 Pro. PC's and the connection is fine .. I don't have to do anything to the modem (it's acting as a switch anyway ..
This computer sits there, when the cable is plugged in, and wireless disconnected .. and there is a blinking of the center icon in the Network and Sharing Center .. jumping from "Unidentified Network" (bench) to "Home" (house) .. like it's trying to connect to "Home" .. but can't because of an IP conflict.
People have worked on this problem for weeks on the web… there must be a diagnostic procedure available.. Please help.. :-)
