BT Infinity, SmartHub, Upload Speed of ~20Mbps Download of ~72Mbps Wi-fi signal strength shows as 'Excellent' on mobile with Link Speed of 300Mbps. Wi-fi calls always connect but there is often a problem with the called party saying the call is 'muffled' or dropping out, although I can generally hear them clearly. Anyone any ideas before I go back to the landline?
