MoCA Networking Question

Hey everyone ; I'm fairly new to using Tivo. I have the Roamio base model and one mini. My question is related to how I have them set up to my network. My cable company just installed a new cable modem/router gateway (Arris TG862).... this gateway would be fine if it was dual band since I have a few devices that can use the 5g band such as my iPhone , android tablet, etc......I had read some bad reviews on this particular gateway's wireless coverage. So I chose to use my own high end dual band router ( apple airport extreme). I called my cable company and asked them to put my cable modem into bridge mode so that their gateway was functioning as a cable modem only and they were good about doing that for me. So right now I'm using my own router and I have one of my MoCA adapters plugged into it to create my MoCA network. I have another MoCA adapter plugged into the Roamio and the Mini just requires the coaxial cable since its MoCa ready.....everything was working fine until this morning. I turned on my Mini and there was an error message saying it had lost connection from the host DVR (Roamio) so I troubleshooted with the Roamio such as rebooting it, etc and was not able to re establish a connection to my network; keep in mind while this was going on other devices in my home were able to connect and use my network just fine. So I ended up calling a Tivo support representative and we went through a few troubleshooting steps and we were able to get the Tivo's to connect back to my network, etc.....So my question is do you think I should keep using my own router and keeping my cable companies gateway in bridge mode or do you think it would be best for me to just have my cable company take my gateway out of bridge mode and me just use it instead of my own router? Do you think my odd setup of keeping the cable companies modem in bridge mode and using my own router could be causing issues with my MoCA network? any advice would be greatly appreciated! Thanks!
