I have fibre broadband with a speed of over 60mb using a wired connection to my router, but over WiFi this is much slower, what is causing this problem?

A lot of laptops and wireless devices using the signal are unable to process internet speeds above 40mb due to the WiFi receiver built into them only being rated up to that speed. For the best connection speed on a fibre product it is always advisable to use an Ethernet (hard wired) connection to the router wherever possible.
