DSL light has been flashing for 6 hours and there's no Internet. I've already followed the instructions in these 2 links however the internet still isn't working. What can I do now?
Best bet would be to contact Support, you can live chat with them at http://yesopt.us/chat2us and then can Lodge a Fault if needed.
If you have done an isolation test, and only had your modem connected to your phone socket, with everything else removed and your not getting DSL Sync, it sounds like you have either a network fault, or a faulty modem. Best bet would be to contact the support people at Live Chat, and then can do line tests and lodge a fault if needed.
