DW1702 driver doesn't support windows 10 in Dell Inspiron N5050

Hi,  a month back , I upgraded from Windows 7 (that was provided with my product, at the time of purchase) to Windows 10. After the upgrade, there were few problems, mouse not working properly etc.

Some forums of Microsoft recommended to clean install the Windows 10.

But after I clean installed it, soon I saw my WiFi wasn't working any more.

I checked the Dell support web page for my laptop, but found that Dell is not testing or providing support for my product (Inspiron N5050) towards Windows 10.

I did follow the compatibility settings and troubleshooting , re-installing drivers and even re-installing Windows 10.

I also found some web pages by Atheros and did update the driver,  but finally what I got is, WiFi connected to my modem but there is no internet access..

I know and understand that Dell is not giving any support for Windows 10, for my laptop. But I want to know if there is any way out , so I could make the WiFi work again.
