hi,

 

 Can you check if th wireless is being detected in Device Manager it may show as Unknown Device or Network Controller

also Check under Network Adapters if you have a Wireless device Detected there.

 If you can't seem to find any. Possible that the wireless Device is disabled

 

    Try entering BIOS

               Tapping F2 or FN+F2 while powering up the unit.

    Once Booted to BIOs

Go under Configurations and Check if the WIreless there is Enabled.

 

Once Enabled tap F10 to Save and Exit

Boot to Windows and download and install the Driver I provided for the Wireless

 

Let me know you findings,

Regards

Solid Cruver

hi

 

If the driver I provided is failing to install

 

 Can you try posting here the Hardware ID of that Network Controller that may be your wireless without a proper driver

Here's how to get the Hardware Id

    - In device manager Network controller with a yellow Icon.

                -Right-click on it and choose properties.

                -Click on the details tab on top

                -Change the property Value, change it to Hardware ID

                -then paste back here what's on the Value

click here for sample pic

 

Best Regards

Hi,

 

Thanks a lot for helping. I too have the same problem. I followed the steps but one this I did not understand below step. i.e

Please tell me where to paste the hardware ID.
