I have a Dell latitude e6420 laptop which is running windows 7 64bit. I have a NEW fresh install with no ethernet drivers.I have downloaded drivers on my other cpu and moved them over and installed them but it has not solved problem.my service tag is :ctvx2r1. please helpWhen you plug cable in do you see a GREEN Light with a blinking yellow light?

If you DONT see a green light lit when cable is connected then try replacing the cable your using to see if this fixes the issue.

Does Device Manager show that all is correct for this Network Adapter or a Red or Yellow icon showing a problem or a warning that something isnt quite right?

If you enter Code: [Select]CMD at start RUN and hit enter and then enterCode: [Select] IPCONFIG/ALL does it show an IP address? If so is this address a 192.x.x.x address or a 169.x.x.x address.

If you see a 192.x.x.x address, what do you see if you enter Code: [Select]PING www.google.com .... does it show that it resolves with an IP Address for the Google server that your system is pinging or an error message that its unable to ping google.I plugged in cable and no light showed up. When i plugged it in in another laptop a light showed up so I dont THINK it the cable. When I open CMD and do ipconfig/all no ip address shows up only physical addresses.Quote from: Brandon on March 20, 2017, 08:09:01 AM
