Optik Tv and Google Nest Wifi Pro

The entire problem is that Google Nest doesn't support multi-cast data. Most third party routers don't. That is what kills Optik after 10-15 seconds. You need the Telus router back in there and then connect the Google mesh to one of the LAN ports on the Telus router. ETA: the Optik box would need to be directly connected to the Telus router again whether it's by ethernet, MoCA or wireless (if you have the wireless Optik box).
