Support contact has vanished

I've had funky stuff going on with my RBW30.  Two seperate units (the first one was RMA'd) fail to connect to the RBR50 router via 5GHz backhaul - even when in the same room!   But my other RBS50 sat connects via 5GHz just fine. This points to the RBR50 router being the problem?

Both RBW30s originally showed 'poor' connection status when I put them in my preferred location (one floor down and one room over in a wooden house - so should easily be within their range capabilities).  So I resorted to using it just one room away on the same upper level (a mere 20 feet thru one wall), which threw acceptable signal into the lower floor target area. But whenever my son moved around the house, he got disconnects on his iPhone 5S.  These disconnects ceased the moment he turned the RBW30 off. 

But a recent change (as I've been playing around, awaiting support feedback after sending them logs) is that suddenly, the RBW30 can get 'good' connection status in that same lower room (but still only via 2.4GHz).  My son now only gets discionnects if he's moving around on the lower floor (which supports a suspicion that I've harbored for a while that the disconnects are caused by poor hand-off between RBR50 router and RBW30 wall plug sat). 

I'm still on V2.1.3.6 for the RBW30 (I'm not brave enough to try the latest firmware (RBW30-V2.1.4.16) posted a couple of days ago.  The last firmware update throttled my speed again.... :mansad:

I'd suggest trying a few power cycles on your RBW30 and possibly some factory resets to it.  My unit has been power cycled at least ten times by my frustrated son. See if that kicks it up to a higher plateau of performance?
