Thanks for the post! I am sorry to hear that you're having issues with internet drops and no range. I apologise for any inconvenience caused.
I have tested things from this side and 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?
Does the Hubs light sequence change at all when the connection drops?
Do you get any error messages?
Also, have you tried connecting directly to your Hub with an ethernet cable and if so, does it still lose connection?
