Orbi PRO SRR60 dropping and another issue also

I've had this orbit router for maybe 6 months and have had the same issue for a long time. Kind of given up on trying to fix it, but now I have another issue.

The long term issue is where any new device tries to come on it keeps coming back saying "can't get IP address".  This happens maybe once a week. I usually just reset the channel 2.4 ghz and put it on AUTO. After hitting apply it usually allows new devices to connect. I have this same exact router at two business locations, and its the same exact problem and annoying solution. I keep hoping a firmware update will fix it, but it never does :(. Eventually I'm probably going to switch to a different brand router, as I keep getting customer complaints. I've owned several routers and I've never seen this behavior before the ORBI.

The other issue is recent, I'm not 100% if it happened after the last firmware update. But it's only happening at one location. The light on the ORBI turns purple, but all hardwired lines still works fine. All WIFI traffic stops working. It happens at least once a day. The only temp fix thus far is resetting the router. I was thinking it was the newer modem, but after seeing several people with similar issues I'm leaning towards the router. I connected another older router to the modem to see if it disconnects as well today to rule that out once and for all. 

I have about 73 devices on at location 1.

location 2, its about 55 or so.

Both are running the latest firmware.
