LAN connection says unidentified network.
I have a DELL LATITUDE E6420, with while INTEL(R) 82579LM Gigabit Network Connection Network Adapter. In device manager the device is said to be working properly. But while connecting to internet, the LAN always says unidentified network. . Giving a fixed IP to it displays the Multiple Gateway problem.
While the Wireless seems to be working properly while accessing the Internet.
Have been trying to figure out the problem..
help me with this..

And,
When I Run Network Diagnostics for Connection,
The Test Result Shows;
- Connection test failed
In details it shows,
- This connection is configured to use a static IP Address
- No WINS server is available for this connection
- No DHCP server is available for this connection
- Ping Gateway 192.168.0.54; failed

It shows all test result passed.
Also the Network Diagnostics cannot identify the problem....

Rush33,
When you reinstalled the operating system, did you install the Desktop/Notebook system software and the chipset drivers first? If not, the rest of the drivers will fail to install. How to Download and Install Drivers in the Correct Order
Start with the Desktop/Notebook system software and the chipset drivers and follow the list.
If you still have problems, Can you run Finding System Information REMOVE YOUR PRODUCT ID and post the information back here.

Rush33,
Places to look to see if your Connection is enabled
Go to Drivers & Downloads enter your service tag number, then select your operating system. Under Network, download and install the latest drivers.
I used these tweaks...
Intel ~ Recommended settings for 802.11n connectivity
Start, control panel, device manager. Click on Network and then right click on your wireless adapter, left click properties, power management. Uncheck the box, allow computer to turn off this device to save power.
I went to the power options, and changed the Wireless Adapter Setting, from Maximum Power Setting to Maximum Performance.
