He doesn't - he only gets that with the BT Modem.I agree with everything you have written above, but how is the OP getting 200Mbps from the Vigor 130. He must have the Vigor connected to the Smart Hub via WAN port.
So you thought that instead of that person being mistaken, he was provisioned with VDSL2 with a data rate of >200mbit?Because he said he phoned BT and they confirmed FTTC. Which isn’t G.fast.
