And I’m back online. Had to deal with the usual 1 PM to 5 PM time slot. The tech turned up, had all the necessary parts and checked the whole thing over. His provisioning App (Android) failed so he had to call NBN to get the MAC address of the modem updated.
Beside the dead Arris, the coax fly lead had also failed and for good measure, he replaced the connector to the joint in the pit on the other side of the road.
