I've recently upgraded from the 4k STB to the Pro Box. It is hard wired to the Smart Hub.
However on two occasions on separate days over the past weekend the signal (multicast) dropped and a series of error messages flashed rapidly suggesting it was my broadband dropping out or the router was at fault. I have an otherwise rock solid FTTP connection with a d/l speed of 74 Mbps. A laptop also wired to ethernet continued to work, and I can find no errors to indicate broadband dropouts in the router log.
Would appreciate knowledgeable input. Thanks
