I have a Dir-655 that has the 1.34NA firmware. In addition to 4 computers and 2 home servers, it is also has an Xbox 360, and Playstation 3 all by wired connections, which work wonderfully. My problem occurs with my Directv that is connected wirelessly via a DAP-1522. Whenever I try to watch recorded Hi-Def video from or to that unit, it stutters and loses connection. Does anyone have any settings that might improve my wireless throughput from this unit? It's been driving me crazy. Thanks
