@Oscarmike what speed to you have to the BT hub? and then from your router? Is it a BT router? utter garbage they are. I suspect that could be the focal point of your problems. What cable do you use from BT hub to your router? Is your router on here? if so, which one?
It is the Huawei 1 port red ends ethernet cable.
Unfortunately I have suffered a brain injury and occasionally I get confused and often say the wrong thing.
