I've been working with UK support on this and I've made a bit of progress. I now have downstream with the same throughput as the BT modem and upstream with a good improvement.....but still not quite as quick at the open reach modem.
Here's what they asked me to change:
Telnet into the router and run the following commands:
adsl txpct 100
adsl rxpct 100
adsl reboot
This should free up the routers own bandwidth reservations (command is
relevant to ADSL but should also help with VDSL).
Via the web GUI, disable QOS. By default, its set to reserve 25% of bandwidth. It should say Disabled in the Status column next to whatever WAN ports you're using.

I suggest open a ticket with tech support
http://www.draytek.co.uk/support/techquery.html
Maybe more complain ... more look into it
IF you willing to keep the 2850n due its features can stick the BT modem to wan 2 but no info from the modem
Other choice is to change for a 2750n
