My modem is currently syncing at 13000Kbps (roughly) and 2123Kbps upstream.
So on the face of things it looks like it supports Annex M.
My issue is that im consistently hitting 1.3mbps on all tests i do (thinkboradband, speedtest.net & btspeedtester).
Here is a screenshot: http://www.digitallyhosted.com/images/btspeedtest.png
As you can see... Im hitting my downstream sync but my upstream seems to be .... adsl2+ upload speeds without Annex M.
Could this be an isp issue or is it likely my modem even though it syncs the upstream at 2123Kbps?
