RAX75 Wireless Drops every hour exactly

I have been having problems with my router dropping my wireless signals hourly on the hour exactly.  My wired computers are fine, no issues, only on my wireless.  I am running Google Chrome Internet Connection log, which shows me the disconnects. 

My router is only a few months old, and along with giving really bad wireless stability, it totally locked up the Web interface in the past few days.  It was still functioning though, but barely.  I did a factory reset, updated to the latest firmware, and the problem persists. 

Also interestingly the 5ghz isn't showing up consistently on my Wifi analyzer tool on my Samsung.  I have been sticking to 2G on most of my devices due to the unreliability of the 5ghz signal.  

I am running a RAX75 router with a R7000 router elsewhere in my home running in wired AP mode.    My AP and Main router are fixed on different channels to prevent interference. I have 46 devices in my home, probably 20 of which are wired. 

Any thoughts?
