So I finally signed up for Orcon's 'Genius' offering. Similar story to what's currently being posted in this forum regarding Orcon's technical and logistic problems.
Date for service provisioning was 17th August. No email or text as promised. After creating a support ticket on the evening of the 17th via the website I was contacted (within 5 hours to Orcon's credit) and told:
"It looks as though you were actually connected yesterday. You will need to factory reset your modem.
If you need help with this - feel free to reply to this email."
Symptoms are that there is an ASDL link up but the onward PPP link is failing to be established. Lights all on except Internet and Phone lights. Factory reset did not resolve the issue (later I have discovered the factory reset actually puts the modem configuration into an incorrect state - the ATM link encapsulation defaults to LLC rather than VC MUX)
Contacted Orcon again and received a boilerplate response containing the correct procedure for the factory reset including the config change required. Still no joy. Have supplied WAN MAC address as requested per boilerplate response.
Hope someone might be able to shed some light on what I may have done wrong or what I need to do to get my internet service back after 3 months moving between houses (for which I was paying Orcon for no service - but that's my fault)!
