So we recently changed from a Cisco RV082 to a Draytek Vigor 2860 router and upon switching we notice the new router does not take advantage of the Annex M which is enabled on our line. it shows the connection in the ADSL Status section as Annex A. This worked fine on our old router and also the ISP assures me that it is still enabled.
There is also the DSL Modem Code setting shown in the picture which only lists AnnexA settings. I have done some research and this setting doesn't seem to show on other routers alike.
Any Ideas?
