I have a BE800 as the main switch in my configuration.  I also have a BE550 and a RE715  setup in a mesh network and an AX11000 as a AP.  The BE550 is using ethernet backhaul and the RE715 uses wifi backhaul.  Ever since setting this up i am having issues with performance. 

If I connect a system directly to each of the routers and do a speedtest I get close to the speed I would expect but I am having issues with certain types of applications.. Microsoft Teams will not connect to meetings, videos will not play, cannot connect to the roomba etc etc.  If I am on a mobile device and I disconnect from the home network and use the cell network, things start to work.

Before getting the BE550 I had the AX11000 as the access point in the same location where the BE550 is now and everything worked well.

It seems like using the BE550 as a satellite in the mesh network is causing issues.  Is there anybody else with this kind of issues?
