Your upstream power levels are too high and that's interfering with your hub communicating with the kit in the street cabinet, as a result it loses synchronisation, which usually appears as slow speeds and disconnections. The VM staff on the forum will be able to advise if there's an area fault with an expected resolution date & time, if not they can arrange for a technician to visit.
Sorry to hear that you're having issues with your services jon_russ5.
I would like to take a deeper look into your account to see if there are any underlying issues with your connection or equipment to do this I will to ask you to clear account security via a private message.
I will pop over the private message in a moment and see what i can find on your account and book an technician if need by.
