Same here. I get about 10 feet of range when using Leopard and the 655. No matter what settings I use, its completely futile. Hopefully Apple and Dlink will get this taken care of.
There is a beta firmware v1.11 available for the DIR-655... I've only tested briefly, but so far I am getting much better wireless connections with my MBP SR.
