Have tried on both Apple and Android phones, re-booted hub a few times, re-installed the app a few times plus all of the other ideas on here. Same error - Unable to connect - Unsupported Modem.
I see. I'd like to take a closer look at what's going on here for you, so I'm going to send you a private message shortly. Please respond to this when you can and we'll go from there.
Thank you for getting back to me via private message. As we discussed there, a technician visit has now been scheduled and booked.
I'm unable to confirm the date/time of the visit publicly for security reasons, but you can check and manage the appointment via your My Virgin Media online account.
