Okay, not even sure where to start. Moving from Australian providers Optus to Telstra based Exetel. The brand new TP-Link 8817 modem is connected to the phone line (with the filter on), the computer via ethernet and the power source. Four lights on the modem are lit (power, internet, lan, adsl). I've gone into the web GUI settings for the modem and done the quick set up. Username/password input, PPPoE connection, 8/35 on the VPI/VCI, connection type PPPoe LLC. All saved. Now I go to set up my connection using the connection wizard. Input password/username. Connect...... doesn't get past the 'connecting through WAN Miniport (PPPOE)'. Now I'm getting 'error 651'. Previously I've tried with another modem and bridged it, using a TP-Link TL-WR1043ND as the router. This didn't work, Windows saying it was a 'DNS server isn't responding'. I'm at a loss with what the problem is, two different forums have been unable to help. Any thoughts guys? Need any more information?
