DarkSynergy did you get an answer to this question? Using two of these to bridge a network would be great on different sides of the house- ie: Router (read: content server) -> 637AP <-Wireless-> 637AP -> Home Theater equipment. I currently have a "G" setup and streaming HD content stutters too much on my PS3.
300 (or even 30!) would be a considerable upgrade over what I'm using now... ~10M max rate using iperf testing...
