If it's a mobile broadband device that you're using, there are a number of factors that can influence your download speeds.
As a first port of call, it's always worth checking our network status checker so you can see if there are any network faults reported in the area.
As these routers rely on a cellular signal too, the placement within your home can have a big imapct, so it's always worth trying a number of locations to see if this affects performance.
