BT start throttling speeds.
Mine for example was choped in half since about 7 days. ( modem synced with full speed).
But they will say its your fault etc.
Currently its impossible to get thru to reasonable person over the phone. I think they know and been told to tell people rubbish.
Reboot modem, its your device problem, bad weather etc.
@Stumpy21 Now that is interesting. I would assume they would not hold all 3 but honestly I don't know. Can you confirm all 3 hubs are the WAN type connected to your ONT and you are getting 900 down and 110-155 up for me?
Yes I am getting full speed on all 3 hubs and one Super Hub was only ever used on a 34/10 connection before. All connected via the red WAN socket.
It may be worth trying the Openreach ONT/modem power down for at least 5 minutes to clear out the cache and make it retrieve the settings from BT, just incase the hub settings are corrupt/not updating
I was one of the trialists for the 900mbs package, and can confirm it is indeed the hub capping your upload speed. I had the same problem when my package was switched over, received the full download speed but the upload was still capped to my previous package. I simply filed an issue report to the trial team who confirmed the hub was capping the upload and they had the cap removed within 24 hours. If resetting your hub does nothing I think your only bet would be to keep calling 151 and hope you get the right person. Unfortunately the specialists who usually deal with this kind of issue have been retasked due to the current situation.
