ADSL not authenticating

I had Telkom install a line, then arranged for the DSL to be activated for this line and then used Axxess as my ISP. The ADSL light on my router is on and stable green, but the internet light stays off. I have made triple sure all details and setting are correct, but same problem keep persisting. I have never been able to get internet data since the line was installed. 10mb line uncapped great! but no data. FANTASTIC. <br> <br> After numerous reports to TELKOM to get this working. NO help. Line syncs but is unable to AUTHENTICATE connection. Multiple routers have been used. I need a telkom techician to come out and show me that he is able with his own router to get data through to prove to me the line works. <br> <br> HELP ME please!!!!!!
