Orbi RBK53 constant disconnects and slowness

I recently purchased the ORBI RBK53 from costco and it has been nothing but problems since I've owned it. I work from home and it is important to be available and connected via vpn to work. I get disconnects/reconnects throughout the day and as many as 5 to 6 times in a row. The only time I get a stable connection is if I'm wired to the router. I did not have these issues with my wrt32acm but replaced it because i had some spots in the house that I need internet.

I have a 2100 sq foot ranch style house with the router in the rear and have the satellites in various location between 25-40 feet away from the router. Currently it is at 25 feet away from the router there are no walls or obstructions and really nothing that could cause a slowdown between the router/satellites. The satellites are currently running at 2.4ghz with poor reception. 

I have tried many different recommended settings including removing daisy chain, enable Mimo, changing 2.4/5ghz output, turning off armour, setting static IP Ports for devices. I also changed the firmware to the last stable version prior to 2.5.1.8. Nothing has helped. I am extremely frustrated and on the verge of throwing the entire setup into the trash can.

I am not sure how netgear can advertise that this mesh WiFi can support 7500 sq feet yet struggle as 2100sq feet.
