They've since been unable to connect the Vigor. The modem status reports back with ADSL2 / SHOWTIME , yet the WAN interface displays no incoming traffic under RX packets. They haven't touched the bridge mode settings, as we're concentrating on getting the basic modem to ISP connection up first.
I've doubled checked the PPPoA settings, (0/100 VCMUX, username, password etc), but can't anything obviously amiss.
Is there anything else I can check on the modem that could cause this issue? I'm feeling guilty after suggesting they use the Vigor! I use the same model at home with Snap's VDSL service without issue.
