@HousleyR123 I assume you have a white Sky hub which should comfortably give you fast enough WiFi as it is a WiFi6 device so something is definitely wrong. To exclude the service to the hub run a speedtest on a device connected by ethernet with nothing else running if st all possibl. Given Wi`Fi speeds can be affected by all sorts of issues ethernet is the preferred connection to establish true speeds.
With WiFi ensure the hub is out in the open and not on the floor as the signal can be blocked by other kit and furniture. Check your device you are running the test on supports WiFi6 (WiFi5 tops out around 700Mb/s) and run tests at a number of times through out the day. Make sure the device is at least 4 to 5 feet from the hub as the aerials in the hub can produce null points closer to the hub.
There is no loss in speed from the exchange to your home with full fibre so the service should deliver the speed you are buying the only exceptions are Sky have misconfigured the account which is very rare but known. The second potential is contention as Openreach use a single 2.8Gb/s fibre between up to 31 other customers which sounds horrendous but actually very rarely is a problem as it is extremly rare any one of those is using more than a fraction of the bandwidth they buy.
