RBR50 Wifi Mesh Internet is Painfully Slow

Aloha Everyone,

1x Spectrum Modem (model E31U2V1)

1x RBR50 Router (Firmware: V2.7.4.24)

3x RBS50 Sattelite (Firmware: V2.7.4.24)

Home Square Footage: Roughly 5000SqFt

I am pulling my hair out trying to get our internet speed to what it should be with the Orbi Mesh System. We have Spectrum Internet at 500mbps. At the modem I receive roughly 579mbps and wired directly into the router I received the same. Wired directly into satellites provides roughly 400+mbps.

The rub is when I go on wifi. My speeds are 150mbps or less. It's a huge drop in speed. My satellites turn blue and are in range of the modem. Each one is roughly 30-40 feet from the other. They are all connected.

What have I tried: 

1. I have changed my DNS settings from automatic to Google DNS. 8.8.8.8 and 8.8.4.4. 

2. Changed wireless channels for 2.4ghz and 5ghz channels. Tried multiple channel configurations. Nothing seemed to change anything for the better.

3. Hard reset routers and satellites. 

4. Security Option: Tried changing from WPA2-PSK [AES] to none.

5. Unchecked daisy chain

6. Unchecked muMimo

Disable IGMP Proxying is enabled in WAN section. Set to Auto

Default DMZ Server is not selected.

Advanced internet settings below: 

Any help or other ideas would be greatly appreciated? I obviously am doing something wrong.

Mahalo in advance
