Hi cahonis,
Thanks for coming back to us on this.
Checking the systems at our end it looks as though the hub is having a long term issue with both the signal and power levels. We won't be able to fix this remotely so I would like to arrange for an engineer to come to take a look at this for you.
I just need to confirm the address to ensure we are booking the visit on the correct account. I have sent you a private message regarding this. Just click on the little plum envelope at the top right-hand side of the page to access your inbox.
Thanks,
