@Thargor as we need higher wifi speeds to stream video, play games etc many people are finding a single free router ISPs supply can't deliver decent wifi in every room. You can do a bit yourself by making sure your Sky hub is in the best position which is out in the open on a surface above things like radiators which block the signal.
Beyond that you need more kit. Sky can sell you add ons like Broadband Boost at £5 per month that guarantees all of 3Mb/s in every room or Wifi Max at £7.50 per month when the guarantee rises to 10Mb/s if you buy Superfast or 25Mb/s for Ultrafast customers which can have up to 3 extenders. Alterntively you can buy your own whole home wifi mesh set up. As each home is different due to layout, type of construction and level of interference there is no one best solution.
