3 weeks ago or so, my local exchange was upgraded to ADSL2+ finally.
For the past 1 and half week, my connection would remain but can't access websites. I changed my router to G.DMT mode and it works fine and connects to websites instantly. Changed the settings back to ADSL2+ and it fails.
I raised this with my ISP who then checked with BT/Openreach. They say there is an issue with ASDSL2+ and would be resolved within few days.
It was fixed a few days later so I changed the settings back to ADSL2+ mode and all is good.
And it broke again a few days later. Once again, all is fine with G.DMT but not on ADSL2+ mode. So raised this issue with my ISP again. They checked with BT/Openreach and just now this morning, they've come back as "BT have just come back to us. They have advised all users in your area set your router to G.DMT mode as they have made some software change."
Is this a bodge job by BT/Openreach to keep the customers happy or is this really an acceptable answer from BT/Openreach?
What is the difference between G.DMT and ADSL2+ mode? Will I lose speed?
Note: I am with TitanADSL as the ISP.
