it's not ADSL2 for sure. ADSL2 requires ADSL2 capable modem and Aztech 3100R is not one them. furthermore, ADSL2 max download rate is 12mbps and 8mbps is just normal ADSL max speed.. but i do agree that their new DSLAM is ADSL2/2+ capable but they are not implementing the new standard yet. now tmnet already upgrade their system and they cap the speed per user a/c and no more on port.. so no matter what's your modem says, your true speed is on which package you subscribe..

my office is 5.4km from the exchange and been using streamyx for the past 2 and a half years.. maybe your place got no free port that's why you have to wait long.

apparently ADSL2 uses different modulation and 3100R is not one of the modem that supports ADSL2 modulation.
