RAX48 is a mess

I recently purchased a RAX48 router. This was to replace my old ASUS RT-AC56U that I have had for serveral years, as this router theoretically is much slower and on occasion (once a week) would require a hard reboot. I have had nothing but troubles sense setting up the RAX48 though. I have had random drops of the 5 Ghz signal where it required a reboot of the router before it reappeared, onstant drops of internet speeds where I wouldn't even be able to load a webpage on my phone, and constant dropping of connectivity from wireless devices and then reassignment of IPs.

I have already tried a factory reset and manual reinstallation of the latest firmware (1.0.2.72). Any other options besides returning it and not buying a Netgear product again.
