IvanPiacun:
Google Mesh uses Auto channels, and changes them, but I assume it handles the change of channels properly between the Google Mesh devices, so you may have no problems if you use ethernet to a mesh point such as a Google WiFi router or access point (except for QoS) but you would probably have problems with the VTV Gen2 STB using Wi-Fi to the Google mesh because of the reasons I gave earlier, as well as the fact that Google Mesh creates a single Network of 2.4Ghz id and 5GHz Id combined, and VTV will connect on 5GHz but not 2.4 Ghz.
You may have QoS issues if connected via Ethernet to the Netcomm Router for reasons given previously, or to the Google Mesh as the Google mesh connects via wired Ethernet to the NetCom router so you may need to get Orcon to check that QoS is set up correctly on the Ethernet port on the NetCom to which the Google router is connected.
You could try changing the SID on the 5Ghz Wi-FI, to something other than used for the mesh, on the NetCom Router and enabling it with a fixed channel setting then connecting the VTV via WiFi to it. You can still use your Mesh for other devices which will not connect via Wi-Fi to the NetCom router if you don't give them the password for that SID or connect them to it via WPS.

Many people interested in this thread are grateful for the assistance attempted to be given by other people. However do you realise that, in this post, your first paragraph (which is quite long) consists of one, long, complicated sentence. Given the technical nature of the advice, IMO this sentence is extremely difficult - if not impossible - to read and to follow.
Ditto for the second sentence - although it is not quite as long. In fact the whole post comprises only four sentences.
There has been some discussion here about the unrealistically high level of tech expertise required by VF of some owners of its VTV units. Sorry but IMO posts like the above only accentuate that problem and in fact compound it - even after bearing in mind that GZ is indeed a tech site.
