Thanks for getting in touch! I am sorry to learn about your issues with your connection disconnecting, I apologise for any inconvenience caused.
I have tested the connection from this side for you, I couldn't see anything out of the ordinary, no errors or time outs inside the Hubs logs and all of your power levels are within the preferred ranges.
Are you still having these issues? if so, how are you connected wired or wireless?
Also, please include a recent copy of your Hubs logs in your response, you can find these by opening your internet browser and typing 192.168.0.1 into the address bar, before logging in it will say 'Router Status' click there and all the information needed is inside.
