I recommend that you phone contact DLink support and let them know about this and get quick turn around information.
Let us know what they say.
Good Luck.
I also have an dhp-1565 and have no issues with usng Vuze .. +50 connections and DL speeds of about 2,5 MB/sec ... Using wifi.
But is I dare to conect an external USB HD to the router then it rashes regularly (even without P2P) ... SharePort is not the most stable SW.
