Just had fibre installed and now getting download speed of up to 50mps, except for my Ipad which is only getting about 1mps. Don't understand why as PC and laptop are both on WiFi as well.
did you split the 2.4/5ghz networks as many devices don't like them combined
did you run btspeedtester diagnostic test? if so post results http://www.speedtest.btwholesale.com/
How you tried splitting the 2.4 and 5Ghz networks as suggested by @imjolly
If you need hel doing so take a look at How do I split my BT Hub's SSID (wireless network name)?
