Thanks man.
About the multiple APs per floor, I've thought about that. But wouldn't that give me 3 SSIDs, per floor? I'm just trying to think what murder that would look like when browsing SSIDs to connect to.
Right now, if I open my laptop and turn on SSID and browse for wireless networks, I count 21 networks in the list... Only 4 I know of in the building.
We live in a busy neighborhood, so that's why I was hoping on keeping the list of SSIDs down.
Unless I am missing something? Wait a second here. You said the "1,6,11 channel rule". What rule is that?
Wait another second.

I think I see what you mean. Setup three APs, with the same SSID (per floor), but on three different channels. Ah hah! Then the user's computer will "flip" from one channel to another in search for a better connection.
That's a great idea (if I am right)!
Oh man... I think you just helped me complete the final piece of the design.
Thanks!
EDIT: Heh, I just read where you said "1,6,11 channel rule on each floor (SSID can still be the same though)". Doh! So I can do the same SSID, per floor. Nice.
