Live view, connections dropping out

Hi all. I have a homebase 2, 2c pro cam, and a dual 2k doorbell camera.

The system is all set up and running, i receive notifications but whenever i try and view live coverage from either camera i get about 5 seconds worth followed by ‘preparing to play’ which then leads to no connection with home bases.

Wifi signal is excellent - the camera has clear line of site to the camera (approx 8m away) and the doorbell just has one thin wall /door between it and the router (approx 5m).

Ive set the homebase on lowest resolution, have updated and rebooted everything but still no luck.

Any ideas?
