Lumia 950XL 5ghz Wifi issue

So I have found when using my 5Ghz N network the phone will lose all WiFi networking.   On first use, it will connect up OK.  But let it sit and come back to it, it will have lost the WiFi network and the ability to see any other WiFi network with "no networks found".  Only a phone reboot will fix it until it happens again.

So far I've experienced it on my Linksys E8350 (supposed AC2400 and MIMO which the 950XL claims to support).  My Wifi router is set for Wireless A or N on 5Ghz, while it can do N, B, or G on 2.4

My workaround is to  only connect to the 2.4Ghz WiFi at this point. 

Anyone else experiencing complete WiFi radio failure like this?

    Thats interesting that your WiFi can only be reset by a factory reset,all i have to do is reboot my phone , still having the issue even though i have the latest firmware and 10586.107. I have even flashed my phone with the windows device recovery tool and set my router to N only. Still nothing. I might have to call this one as hardware and go into the MS Store.

    it is related to our routers. However, I cannot see any of my neighbors' 5Ghz WiFi signals, only their 2.4Ghz. […] Surely my 10 adjacent neighbors cannot all be using the exact same router.

    Your router (or something else) might kill the 5 GHz unit in your Lumia and therefore, you do not see anything on 5 GHz anymore. Obviously, this is a bug in Lumia because nothing external should change your phone. Nevertheless, to reproduce this issue, as many information as possible are required. One puzzle piece might be your Wi-Fi access point.

    Of course it is the phone because other devices work for you. However, because my Wi-Fi at 5 GHz is no issue with my Lumia 950, this software bug arises in a combination of devices. Microsoft must get aware of this combination to analyze this issue. Then, Microsoft is able to A) solve this for all users, B) give a switch for affected users, C) or at least explain the cause.

    To test your hypothesis all I have to do is unplug my router and I should start "seeing" all my neighbors' 5GHz signals.

    Please hold ....

    Test 1: Unplugged home router, rebooted 950 XL, waited 1 hour.  Results: No 5GHz signals

    Test 2: Left home, rebooted 950 XL, looked for other signals throughout the day for 8 hours. Results: No 5GHz signals

    Conclusion: It's the hardware!!

    Next theory?
