It may be worth doing a factory reset of the SH2, bearing in mind this will reset all passwords \ SSIDs back to their default values and any Port Fprwarding rules and MAC reservations will be lost unless backed up beforehand.
Thanks for the post! I am sorry to hear about your persistent issues with no WiFi connection on your Hub, I apologise for any inconvenience caused.
I have tested your connection from here and I can see that all of your downstream power levels are too high and have caused a number of T3 time outs inside the Hubs logs as a result. I would like to arrange for this to be investigated further 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 get this sorted for you.
