Using Speedtest app on my iPhone right next to the box I am able to get 200mbs
are you saying that the v6 box will struggle to deliver on demand and streaming services unless a wired connection is made to the router? If so then this was never made clear and having multi-room, a wired connection to each V6 is not possible.
my contract has expired so potentially time to move back to sky
Your main V6 box would need to be a wired connection but your extra V6's can be wireless, we do just always recommend anything you're using to stream services would be best on a wired connection as even though your WiFi is running great on your phone it's not guaranteed over wireless connection especially when you're streaming and need constant stable connection as wireless can be unstable compared to if you were using an ethernet connection.
No we don;t name them separately as if they are names the same, the devices in your home should just switch between the 2 connections and you get a more seamless connection.
If you would like to have the 2 connections named differently, you can sign into your hub by entering 192.168.0.1 into your web browser and sign in. Please keep in mind, if your hub is in modem mode you will need to go to 192.168.100.1
