I have been running this beta version for a few weeks now.  

Great job under MESH they now included the main router to show connections it really helps a lot.  I do see a small problem for 2.4 devices ( doorbell , light switches loses its connection but after time connects back)  

One of the things I really like is the second internet connection that I need as backup however I hope maybe we can get additional options currently there. there are two options failover or loadbalace.  

Under loadbalace you can adjust the weight percentage only.  That would be great if the connection speed would be the same in my case I have Fiber Up/Down 1GB and  Coaxcial 500MB down and 30MB up.  

If possible  

1) put in max connection speed up and down for each so it can load balance correctly.  

2) Allow the ability to direct each connection to what connect it can use e.g  Gaming computer is dedicated to GB port 1  Doorbell can use GB Port 2 

anyway overall its working great the additional visibility over the network is a huge plus.
