RBR50 Sky Q Intermittent Connection

Hello All

I have recently had Sky Q installed with the 2 TB box and 1 Sky Mini Box.

My set up with Orbi is as follows:

Vodafone Broadband and Router

1 x RBR50 in Access Point Mode

2 x RBS50

All are set up over Ethernet Backhaul.

My Sky Q and Mini Box are both hard wired Ethernet to switches (unmanaged Netgear)

Although everything works ok (mostly) I have noticed on the sky q and mini box that the Network Connection "tick" turns to a cross and back to a tick again every 10 seconds or so.  This is constant and does not stop, however it has to be said that the online services work most of the time.  Occassionally, if I go to Box Sets it may say I have no connection but a minute or so later it will be OK.

So, to test this, I plugged my Sky Q directly into my Vodafone router to get a direct connection to the internet, unfortunately the problem was the same.  However, as soon as I disconnected the ORBI routers from my network (they were still powered up, i just disconnected the Ethernet feed), the problem went away and the tick was consistently on.  The moment I re-connected the ORBI to my wired network, the ticks/cross started again.  This led me to believe it had nothing to do with any kind of wifi signal clash as the orbis were still on, plus please note, there is no connection from my Sky Q or Mini Box to my Wireless network run by the ORBI, it is all wired.

As mentioned above, I know it is all working pretty much all the time, but I like things to be working properly otherwise thing inevitably start to go wrong in the future.

Any support would be appreciated.
