Network Card not working

[kahitano08]

I have upgraded my Sony Vaio CR510E laptop to windows 7 a long time ago. Just recently found out that my network card is not working. It can't get an IP ADdress. All I get is the private IP 169.254.255.245.

I tried installing driver for the old Vista OS and it didn't work. Tried installing from automatic windows detection and it doesn't work. I don't know what kind of network card I have. Does anyone have any suggestions?

Wifi is working fine.

Welcome to Seven Forums. Go to Control Panel\All Control Panel Items\Device Manager and see if there is a yellow icon on Network Adapters.


If so right click the device, then update driver, Search Automatically.

There's no yellow icon in there. I've tried clicking on update driver and it only says that I already have the latest driver installed.

And also, even if I set a static IP and gateway on the network adapter, it's not able to connect to the router (192.168.1.1)

First thing you should do is check hardware. That means router ports cable and the nic port on the back of your computer

Then ping the internals open command prompt and type the loopback " ping 127.0.0.1 " if your physically connected in the first step and you get losses here its a software issue. resetting tcpip might fix the issue it may also be a anti virus issue or something like that

So I connected the cable from laptop lan port to a lan port in the router, did a PING 127.0.0.1 and was able to ping successfully. I have already disabled antivirus.

Try the Device manager again and uninstall the adapter and delete the driver and reboot.
