@Tammy147 hiw are you measuring the speed? If its on a device connected by WiFi then you msybe just measuuring the WiFi speed. Sky normally test the speed to your hub daily you can find the results in the Service Checker in thecMy Sky app if the speed is lower than the guaranteed speed the app should offer further help.
If those results are OK your issue is poor WiFi. Poor WiFi coverage is probably the most common question we get in the forum. In many homes a single Sky hub cannot provide a usable wifi signal in every room due to the layout and type of construction of the property especially in older homes. Assuming the hub is in the best possible position which is out in the open on a surfsce then the only answer is additional wifi sources.
Your choice.is to either buy Sky's add-on WiFi Max bundle which can supply up to 3 extenders see https://www.sky.com/help/articles/sky-wifi-max or buy your own wifi system and use that instead of the Sky hub's WiFi.
