Internet lagging is the sky app telling me lies?

[Lizalisa]

My Internet has been lagging, when I go to my sky app it tells me I'm getting 72 mbs so I went on and tried many other Internet speed checks and they all are coming back with speeds of around 8 mbs

@Lizalisa no the app and the speedtests are simply measuring two different things and both are true. The app measures speeds to your hub the bit Sky guarantee. The speed tests measures the slowest part of the connection to a remote test site and the restriction  is likely to be the speed in your home network. The speed to your hub is the total bandwidth available for all of your devices to share and if your devices are connected by wifi that is frequently the slowest part. 

Slow wifi is incredibly common see Sky Help - Slow wifi for somevideas of how to improve it.
