I just changed to ADSL2 (30Mb), and somethings wrong with my WAN Miniport PPPoE, the download speed drops a lot.

But the speed is become normal when I use the router built-in PPPoE dialer or use my nettop connect to the modem directly:

- Desktop --> Modem = 18Mbit
- Desktop --> Router --> Modem = 30Mbit
- Nettop --> Modem = 30Mbit
- Nettop --> Router --> Modem = 30Mbit

I then installed RasPPPoE instead the WAN Miniport PPPoE on my desktop, problem solved. So could you guys please tell me how to fix the slow Windows built-in PPPoE problem? since I don't want to use a third party dialer.

Thank you so much for your kindly help.
