I was testing out an UAP which I already had a created group and wireless network for. I set up the name and password and everything was good. I continued my installing of 4 more UAPs, and hooked up my unifi switch. During this time I updated my controller to the new version. Got everything connected and working. I checked back on each of the UAPs making sure they were all assigned to the group, and they were. I also made sure all the details of the group were right and they were.
I finished testing out the new wifi and it was working great. Only little issue I had was when I was moving from one area of the building to the other, the wireless connection was not automatically switching to the closest UAP. I would basically have to turn off my wifi on my laptop, then turn it back on, and then after that it would connect to the closest UAP. Maybe I wasn't giving it time or maybe thats how its suppose to work, im not sure?
I would think the closest UAP would be the one it would switch to but maybe whichever UAP you first connect to is the one my laptop tries to stay with until theirs a complete signal loss, then it would connect to another UAP. Correct me if I am wrong?
So I read up a little on Zero-Handoff and thought maybe thats the soultion. But when I tried to activate it, the controller would not let me. I'm going to attach a picture of my screen, but it basically is shadowed out that I cannot select it. What am I doing wrong here?

Rather than enable the ZH to an existing wlan Group, create a new one and enable on this the ZH feature, then, on the APs, configuration, wlans, wlans group drop down menu, select the wlan-group with ZH.
Bear in mind that ZH 'needs' to be tuned really fine, and doesn't like 'busy' wifi environments ...I suggest instead to try with the minRSSI

You'd do better by manually setting channel and power settings (auto / auto is bad -- it means "some random, usually bad channel" and "high power"). Looks like you're using 2.4 GHz only, so use channels 1, 6, and 11 - they're the only non-overlapping channels - and set power to "medium" (or "low" if the APs happen to be close-ish together)

Heres a picture of my setup, its for my hotel, all the UAPs are on the second floor, the building is a brick building so a lot of resistance between the walls. You can use the cars as a scale of the distance.
So you suggest forget the whole ZH thing, just adjust the channel and power settings. Do you think the UAPs are close enough for low or medium setting just from a visual perspective of the map?
Also how would I adjust the channels? Put them all on one channel? Rotate them on different channels? Sorry I'm a novice on all this
Something like this?
UAP uni205 - Channel 1
UAP uni209 - Channel 6
UAP uni214 - Channel 11
UAP uni218 - Channel 1
UAP uni220 - Channel 6
I was going to try this wifi network setup (once I get all the settings right) and see if it was going to be enough for both of the floors, I may add some UAPs on the first floor inbetween the UAPs on the second floor, just a future consideration.

Try with medium power at first, wich corresponds to 12 dBm on these units. Adjust it to a little more, or a little less if needed.

@ravip -- yep pretty much, channel separation is spot on. Now, the only thing you need to do is check that those channels in those locations are fine (sometimes channel 1 is congested in one place, but not another, so you've got to play around with what is where).
However if you've got two (or more) floors, the first (and third?) will have spotty coverage no matter what.

I'm using 4.6.3
If your trying to find zero handoff settings?
Go to settings on the controller ( click on the bottom left with the gear symbol )
Then click "wireless networks"
Then at the top right, there is the row that says "WLAN group: Default + - Settings", click the settings and a box with pop open with the option to do zero handoff
