@Alex_Woo while spedds to your hub can possibly be the issue it is far more likely to be WiFi speeds in your home. It is easy to check as Sky test the speed to your hub every day the rsult is in the Service Checker in the My Sky app. You can also test the speed yourself by using a device connected by a direct Ethernet cable which should deliver close to 900Mb/s.
WiFi spedds vary due to the layout and type of construction of your home but a devicecin the same arwa as the hub should also get spedds apprizching 900Mb/s over WiFi if it supports WiFi6 and tge hub is out in the open.
