Mobile Me, the AEBS and very slow file transfer

[MaskingTape]

So I have the back to my mac enabled on my AEBS so I can access the hard drive I have hooked up from anywhere. That part works fine, I can see the drive and browse it with no problem but when I go to copy a file from the disk it is INSANELY slow. Granted my internet at home isn't fantastic, but I can get 50k up no problem. When I copy from the hard drive i get about 40k every 10 seconds. A 1 meg file took well over 15 min to copy. It's not a steady stream, it keeps stopping/sending/stopping/sending. Anyone else use this feature and have the same problem or know what could be causing it to go so slow? I restarted the computer, the modem, the AEBS everything.
