I've had this problem or something similar. I'll link the thread from the Virginia forums.

The problem I have is both boxes keep losing connection to each other and the only way to get them reconnected is to go into the settings of the V6 and reconnect one or both of the boxes to the WiFi. Any idea how to keep them connected?
On a separate note the Hub 3 is on auto 2.4/5ghz or whatever the setting is. Is there benefits to changing them to two separate things rather than one?
