Yes, that is part of the procedure the BT advisor asked me to perform and also included reseting the hub and rebooting the BT TV box. When I originally upgraded to fibre 100 I totally lost broadband and the engineer who came replaced the ONT box from a battery backed up unit to a battery free unit as he claimed that was the reason for the lost connection, oh, as well as a kinked fibre cable in the roadside box which he corrected, I am still getting 145 mb on download so the broadband is fine, just the Sport on the TV box, tablet and desktop are fine.
