Thanks for getting in touch to let us know about your issues with your broadband disconnecting, I apologise for any inconvenience caused.
I've tested things from here and I can see that you're only locking onto one upstream channel and the power levels for that are too high and will need an engineer to attend in order to resolve this for you.
I will send you a PM (purple envelope at the top) detailing what's required in order to proceed with making the booking, please respond to me there and I'll ensure this gets sorted for you.
