Thanks for the post! I am sorry to hear about your issues with slow speeds, I apologise for any inconvenience caused.
I have tested things from here for you and I noticed that your Hubs logs seem to show a number of T3 time outs inside, I would like to arrange for an engineer to attend and investigate this further for you.
I will send you a PM (purple envelope at the top) detailing what's required to proceed with making the booking. Please respond to me there and I'll get this sorted for you.
