@ErikHarakaly if you resd your contract you will find are paying for the speed of the connection to your hub which should be up to 900Mb/s and not lower than 600Mb/s. Sky like every other ISP do not guarantee that you will get these speeds over WiFi but you should if you use a direct gigabit Etherrnet connection. WiFi speeds depend on the lsyout and type of construction of your home. Sky's WiFi Max package whuch is an extra guarantees 25Mb/s in every room.
In practice very few apps can use 100Mb/s except while downloading so speeding up WiFi which is possible if you buy suitable WiFi equipment is rarely worth the money.
