Andrew,
That is correct. I have 3 ap's in my and when I wander
around the house and outside and the signal gets too low on the ppc it will
switch to the strongest one that it finds. It works very well although the
handoff isn't as seemless as I want. If viewing streaming media or using
voip, the media will reconnect then buffer and continue in most cases. With
voip there is a point where nothing can be heard then after a few seconds it
all comes back. Other than that it's not bad. You shouldn't have to turn
your ppc off then back on to get it to associate with another ap. I see you
have a 4150, have you installed the latest rom update for it? One of the
things it had improved was roaming and it also added WPA encryption which
was very much needed. I haven't installed the rom yet as my 4150 isn't my
main ppc.
