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?

    In UK I am stuck with 2.4ghz (99% uptime)

    if I try to use 5.0ghz (lower channels) I get NO INTERNET AVAILABLE on connection

    if I try to use the 5.0ghz (high channels 100-140 etc) I can get internet but not for long

    I replaced my Linksys e4200 with an asus ac5300 and wasted money as it was not my router

    I bought another 950xl and its exactly the same

    I am guessing its UK model hardware fault now and I will live with it till Samsung note 7 arrives

    I guess the 5GHz didn't drop off then? Your post was almost 2 months ago.  What have you discovered?

    The phone has been out for what 7 months now and they have not fixed this issue? Pathetic.

    Hello - made exact the same experience with a 950 DS with your FW and all previous ones as well as with 01078.00038.16025.39021.

    So I just got my Lumia 950xl two days ago. I had a lumia 920 previously.  I have an ASUS RT-N66u router and a ASUS RT-AC3100 router.  Both offer 5GHZ networks HOWEVER one is AC and the other is N.  My 920 would work fine with the N 5ghz network of course but not the AC since it didn't have an AC radio.

    Fast forward to 2 days ago with the 950xl..  It will connect to both 5ghz networks HOWEVER after either leaving the range of the routers or a few hours it drops the 5ghz connection and switches to 2Ghz.  If i shut off the phone and turn it back on 5ghz comes back for a few hours and again will drop. 

    My build and version info is:

    Version: 1511

    OS Build: 10.0.10586.218

    Firmware revision number: 01078.00038.16025.39005

    Hardware revision number: 4.0.3.1

    Radio software version: BO25c43.00009.0001

    I opened a case with Microsoft support. However they appear to be dragging their feet.

    Update.... My phone is the dual sim model. I only have a single sim in it though. I thought what the heck let me try something. I turned off the sim1 one (sim2 wont turn on because there is nothing in the  slot) and with sim1 off 5GHZ shows up.  Turned sim1 back on and waiting to see if/when 5GHZ drops off.  I'll keep you posted.
