Can I use the TP-LINK TD-W8960N (ADSL2+) as VDSL modem
Solution 1:
The TD-W8960N is only an ADSL modem – it literally does not have the hardware that could understand or generate VDSL signals.
Many ISPs provide "VDSL" connections that actually support both VDSL and ADSL modems, so the TD-W8960N should still work with such a connection – but only in ADSL2+ mode and ADSL2+ speeds.
