RBK50 Disconnects driving me crazy

Thanks guys

Well, at this point I can answer a couple of the questions- What type of Modem am I using? This is easy because I just went down and replaced my modem yesterday at Spectrum because I knew this had to be the problem, my old modem (which I don't know the model #)

My new Modem is an Arris TM1602.

I probably have 30-40 feet between the router and satellite.

I have plenty of neighbors around me that have WiFi, sometimes more than others but on average probably 3-4.

Orbi definately has worked more often than not but still going off for 5-15 minutes at a time is definately unecceptable.

I have 2 things plugged into the router, my computer and my Sonos

My home is a whopping 2,000 sq ft but I'd also like to have it reach my back porch which it will while it's working.
