Hi @Griffno1 thanks for your post here, although we're sorry to hear of the concerns you've raised here.
If the speeds are going to your Hub, then it wouldn't be a Hub issue if the speeds aren't going to the device, it could be a device issue here, particularly when it comes to WiFi.
To rule out anything more serious on the network, can you please try the same speed test, but to a device connected via ethernet cable to see if the speeds are more up to scratch?
Many thanks
