Thanks for the post! I am sorry to hear about your issues with your connection WiFi light flashing constantly, I apologise for any troubles incurred.
I have tested things from here and I can see a number of time outs inside the Hubs logs, I would like to arrange for an engineer to attend and investigate things further for you.
I will send you a PM (purple envelope at the top) detailing what's required in order to proceed, please respond to me there and I'll get this sorted for you.
