I have not seen any broadcast storms for a long time now. I have a RBR connected to a RBS that has 4 Gb LAN switches in between that are daisy chained. Have not seen any problems like this in a long time. I know Did see this once and I fould the RBS and my VoIP devices were in IP address conflict at the time. Once I got the VoIP device on a IP address reservation away from the RBS IP address, all was good.
How do you have RBS ethernet connected?
This is NG recommendation:
" Recently after buying a new fully managed switch to try and give me tools to fight this it actually had a bigger impact to my network, but this allowed me to do more troubleshooting and verify my suspicions." What is the mfr and model# of the switch being used? If this is a managed switch, you need to disable ALL IGMP protcols on this switch if you use it between the RBR and RBS when ethernet connected. Possible your switch your using maybe a cause as well.

Also disable any green ethernet features on this switch if possible. Some switches you might not be able to so you'll need a non managed non green ethernet switch to use with Orbi.

Its always best to connect the RBS wirelessly FIRST to make sure it connects well to the RBR, then once this gets established, connect the RBS to the RBR via ethernet directly to the RBR using a good quality LAN cable. CAT is is recommended. Once the RBS is connected and everything is working here, then place the RBS out at the remote location and connect it there.
