Hello I have Inspiron 14RN4010 laptop. There is problem of WiFi connectivity for two days now. It was ok before two days. 

Troubleshooting gives result of "The windows wireless service is not running on this computer", after asking to repair as admin it comes back saying "problem found not fixed"

Also trying running service from services commond, but after running the program it stops giving error of "error 999:error performing inpage operation"

I have tried installing the driver files, but the problem is still the same.

Can you suggest a solution & what could be the problem?

Thanks & regards,

A Murugu
