RBR20 Connection Issues

I have had an ORBI RBR20 and two sattelites for about a year and a half. At first, it was connected to a DSL wifi router / modem, but in the spring we upgraded to cable. Since that time, it has been connected to an Arris DG2470A. We have been told by the cable company that we can't use our own modem. 

 

In the first setup, we had slow but reliable internet. We had no troubles with the ORBI for the year or so that we used it with the DSL. Since moving to Cable (and the new modem / router), the internet is FAST (for us), but it drops out at least 5-6 times daily. The cable company checked out line and shows a continuous connection. 

 

If I go into the orbi box, it always tells me that the internet is "good." I have discovered that if I run a "test" of the internet setup in the orbi box interface, the internet starts working again. If I am physically looking at the ORBI and the Cablem Modem, the ORBI shows something happening (ring lights up) but the modem shows no activity. I assume that means that my intenet connection is still good. 

 

Any suggestions? I do know that the Arris NAT is in "bridged" mode, which is what I had the DSL modem set to previously. I am a bit nervous to poke around too much because I don't have any device with ethernet. If I lose connection to the ORBI via wireless I am in trouble!

You do want to turn off the WIFI on the ARRIS, so you won't get interference. I would check the cable from the Arris to the Orbi router, and change it, to at least cat5e, if it is cat5. 

Who is your ISP and what equipment did they provide?
What is the current firmware on your Orbi device?
What device is your Orbi router connected to?

Then try these settings:
Disable Circle, Armor, Daisy Chaining, Fast Roaming, IPv6 and uncheck 20/40Mhz Coexistence.
Enable WMM, Implicit BeamForming, Mu-MIMO
Set Short preamble mode. Save settings, reboot Orbi.
