I've just had virgin broadband installed and on a speed test I'm getting 113 mbps but on a speed test of my wifi on my iPhone or the iPad I'm only getting 22-23 Mbps I'm not using the virgin wifi as I have an apple time capsule that broadcasts in 802.11ac is this as fast as it's going to get or can any improvement be made. the distance from the tc doesn't seem to make a difference as I've checked both close to it and downstairs from where its located.
