Service Tag: CN3BK82 - Not able to see Wi-Fi icon and settings all of sudden...!

Dear Support Team,

I have purchased the Dell Inspiron 15" 7559 laptop in Dec 2015, in USA, later came back to India. Till couple of weeks before i had no issues, today i found missing Wi-Fi, settings and icon, not sure how it was disappeared. I could only suspect and remember that i have done online Win10 update when it prompted.

Need your technical help in this.

I have tried, couple of recommendations given in dell portal, by trying to install the network drivers from Dell site, as well Intel site; Network_Driver_MF79M_WN32_18.33.0.1_A03.EXE, Wireless_19.0.1_PROSet64_Win10.exe, respectively.

When i tried to install driver (Network_Driver_MF79M_WN32_18.33.0.1_A03.EXE) from Dell site got error, below is the error log of "Network_Driver_MF79M_WN32_18.33.0.1_A03", for your reference.

When i tried to install driver (Wireless_19.0.1_PROSet64_Win10.exe) from Intel site, got successfully installed message, but still i couldn't see the Wi-Fi settings.

In both cases, restarted the laptop.

Appreciate your suggestion to fix this issue.

Best Regards
