XR700 lost WiFi after FW upgrade to R700-V1.0.1.50-0626 from NetDuma

Some last remarks:

Flashing in some earlier dd-wrt bin revived the Wifi.  The 2.4G/60 came back with the 2.4G completely normal and very stable with observed full RF power.  There are some known FW issue that did not turn on the 5G.  Recent bins don’t load properly either, as they are betas being worked on. 
This at least demonstrated that no general HW issue and the 2.4G is good and 60 turns on.  I have also verified that there is no issue in the ART of the mtd.  But will have to wait for a new good dd-wrt bin when it comes out.     

Now flashing back to an earlier NG/Duma FW showed in the Dashboard GUI that all WiFi’s are enabled, but only the 5G radio was actually detected with temperature shown properly.  The 5G also has very low non useable RF power level but it is there, seen in WiFi Analyzer, not very stable, probably not loading the calibration properly.  2.4G Atheros controller was not loaded but the 5G was under Duma. 

I have concluded that there is no HW issue in my unit as all radios are not detected but definitely there is something wrong with the NG/Duma FW that caused the corruption.  Will have to set this aside.

Don’t update to any NG or Duma FW unless you are under warranty or NG is not responsible for their new released FW on your out of warranty unit, as they only would recommend you to buy a new unit.  Not.  I haven’t found another equivalent one with SFP+ and 7 ports with 2 aggregated ports that I all used, but too many issues with this XR700/R9000.  NG has good designs but lacking in product reliability and support, from my multiple experiences.
