A proper comparison test would have both routers sitting side-by-side and look at issues of stability, speed, both frequencies and signal strength at different distances & heights.
I can comment on the DGND3700 in my home environment, but I have no experience of the WNDR3700.
From my perspective, the WiFi is now very stable on both the 2.4GHz & 5GHz channels. The signal strength in my home is very good and I have had some tasks running over a period of days without it dropping once.
Unfortunately I can only use channels 36-48 on the 5GHz frequency. This is down to the firmware not enabling the additional channels for Europe. Saying this, I live in an area where there is a lot of WiFi routers and mine is still the only one that my Laptop can see on the 5GHz channels. :cool:
