XPS no wifi and ethernet working

Hi All,

I had windows 7 automatic update and later i noticed that both ethernet and wifi not working.

I tried the following with no success :

1. Re-installed the adapter driver for wifi and ethernet.

2. Disconnected and connected the WLAN hardware.

3. Downloaded latest drivers and installed it.

First i could see my wifi network in my laptop but after uninstall and re install the driver, my laptop cannot detect any wifi signal. I tried to add wifi network manually but it didnt work!

Appreciate your help!

Best Regards,

Vijay
