Sudden loss of WiFi, what is Bernie?

I have a RAX50 and have been having this problem on and off since I purchased it, like I had it maybe 5 days then this started intermittently. The router randomly renames itself Bernie_RAX50 and that is not the default name of my device. I do have my router very locked down as far as security for both primary and guest network with nothing left open. I have to do a factory reset and rebuild my network each time. This is the most garbage POS I have ever encountered and a MAJOR FLAW which Must be in the firmware or there wouldnt be so many people with the same exact problem where it resets to the same SSID name. I have seen many people across the world comment this issue now (found under a Google search). Were I not a IT Sys Admin for over 20 years, and just a novice home user I would be at my wits end! HORRIBLE of Netgear, HORRIBLE!!!!!  Such an expensive device which has inherenent flaws out of the box.
