XPS 1820 AIO, WiFi connectivity issue

Hello Geeks,

I'm having WiFi connectivity issue, I'm not able to see any available WiFi networks. When I reset the WiFi adapter or restart the computer, it solves the issue most of the times, though issue comes back in few minutes. I have windows 10 and I have even reset the windows 10 fully to give it an attempt, still issue persist. I have installed all latest drivers as per Dell auto-detect recommendation and updated to latest BIOS. I have also checked many discussion forum if anyone had same issue, and tried solution proposed for similar issues. Nothing worked. I will appreciate assistance on this.
