RBE771 Connection Constantly Dropping

I have an RBE771/RBE770 that I have had running for just under a year. My current setup I am using Ting and I get 2GB up/down.  They have a fiber modem which I run into the Orbi and I also have a NETGEAR 8-port 2.5G Multi-Gigabit Ethernet Plus Switch. 

In the last month, I am getting 10-20 drops a day. I can't hit a website at all and everything comes to a grinding halt. Sometime the connection comes back after 3-5 minutes but lately I am just unplugging the Router to reboot it.  

My firmware was current in the admin console but a Netgear search said the latest was V10.5.20.3 so I loaded that up about 4 days ago. No change on the drops at all. 

I contacted Ting and they of course said everything was fine on their end. They show a solid connection and no errors. 

Any suggestions on troubleshooting here? I will probably replace all cables this weekend for grins but this is nuts on a less than one year old Orbi Mesh system. My prior Orbi system was amazing for years but was limited to 1GB so I had to upgrade when Ting gave us 2GB. The logs I am looking at are basically worthless from the admin panel.  Just basic info and nothing isolating an error. 

Appreciate any feedback!
