OK here is my setup: I have: A MBP (N capabilities) and a MB (G capabilities) both wirelessly backing up to 500GB Time Capsule. I also have a 500GB external hooked up to the Time Capsule which stores my movies and TV shows which stream to my Apple TV and XBox. I also Have an iPhone and a Wii (G capabilities). I was wondering if it is possible to hook up my airport express (G) to the Time Machine and put everything wireless on that band and put my MBP on the N band? However, will I still be able to do wireless Time Machine backups from the MB and access the external hard drive? Thanks For any help!
