Go to Start/Run and type devmgmt.msc and hit enter. In the Device Manager, is there a yellow mark next to Network Adapters? If so, you will need to download the driver for your NIC/Network adapter from your computer manufacturers support web site, save it to a Flash drive and install it on this computer. If there is no yellow mark, then make sure your Ethernet cable is plugged in and is plugged into your Router/Modem and it is turned on. Try restarting Router/Modem and computer. Then go to the command prompt type ipconfig /release and hit enter. (It should say that there is no IP address to release or something like that.) then type ipconfig /flushdns and hit enter. Now type ipconfig /renew and hit enter. It should come up with a new IP address unless there is a problem with your router (it's not broadcasting DHCP) or is not connected or a problem with the Ethernet cable.

 

Yeah, it was the driver. thanks

 

I moved your thread to the Networking Forum why did you start another thread? I don't feel this is a operating system issue that is why I moved it.

Please do not double post @!

 

My bad, I didn't realize I wasn't in Networking until I posted and idk how to delete threads, so I remade it in networking.

 

Hold the Windows key and press R, then type devmgmt.msc

Please respond to all the following steps.

1. Under Network adapters, please tell me all the devices listed.
2. Are there any devices under Network adapters that have a red x displayed?
3. Also, are there any devices anywhere in the Device Manager display with yellow ? or ! displayed?
