@Selman you can see the speed of the service to the hub by running Sky's service cheker https://www.sky.com/servicechecker where you can see the history for the last month by clicking on the speed test result. If that shows an issue it should offer help if it doesn't then call Sky but be prepared to be told their diagnosticsxare not showing an issue.
