Firmware version is currently loaded? Found on routers web page under status.
What region are you located?
How are you determining that you are hitting a 2Mb limitation?
What ISP Service do you have? Cable or DSL?
What ISP Modem Mfr. and model # do you have?
I just helped test up BigChucks 857 and he's on a 50Down/10Up ISP service and his Traffic Shaping and QoS are enabled and speedtest.net reports him getting those speeds.
I haven't heard any information about it from DLink as they are aware of it. Most people have been disabling QoS as QoS is only for LAN side connections for multiple devices being online at the same time and ensuring there is fair use of the WAN side connections.
If your not satisfied with the 857, I would recommend a DIR-856L, 836L, 826L or 835 as these have higher rated UP Link settings as seen here:
