Wifi not showing

[Kuttalamsankar]

Hi,

I am facing issues with my wifi driver. When I switch ON the laptop, wifi works fine for 5 to 10 minutes. But after that, the wifi driver keeps on disappearing from my system. When i ran the hp diagnostics hardware test it saying wireless module missing. Kindly assist me on this.
