Thanks for the suggestion.  I have set that to the level I believe things drop off at and will see if that helps.

I've been playing around with the minimum RSSI values for the last couple of days and it seems I can minimize the "hangs" when connected to an AP with a week signal but to really make a difference I have to get the value up to betweem -80 and -85 but at that level, I wind up dropping WiFi completely in many places. Before I invest in additional APs, I am tempted to buy a 3-pack of the original LRs that support ZHO and see if that works better.  I could always return them if they didn't and sell my AC units on ebay since it doesn't look like there is going to be a trade-in/downgrade offer coming.  Thoughts?

@UBNT-Brandon, did you have any thoughts about my question about the original LRs with ZHO vs. my current setup?   See

The single most important thing your company should be working on is Zero Handoff for your newest models. Stop everything and get it done.

Ubiquity has a great product line with a great controller but it's all a non-starter for sites with multiple APs. You can't even begin to think about installing this stuff without it. Unless you want really pissed off unhappy customers.

RSSI is not a solution.

Hi @ProSoundSudbury,


So the fast roaming solution for Gen2 is soaking in Beta now:


To sign up for Beta, go here:


We'd appreciate any/all help testing as we agree we want to get this out ASAP - but we of course view stability and maintaining performance as paramount - so we're soaking this in Beta until we are confident it (1) adds sufficient capability for seamless roamding while (2) not degrading system stability/client compatibility and (3) doesn't adversely effect performance.


A note on zero handoff vs. fast roaming:

Zero-handoff is actually a single-channel architecture.  So it's irrelevant for most modern WiFi installs - and should only be used in the lowest-density situations (as all APs have to be on the same channel) - and effectively eliminates 802.11ac performance when used (hence why we did not implement this on 802.11ac platforms - and are focusing on fast roaming instead).


The advantage with fast-roaming is you can get as-good or better roaming performance - without the sever performance downsides of single-channel zero-handoff (which was only useful up to say circa 2013).

Hi @UBNT-Brandon,


I don't see a mention about the fast roaming solution in the beta release notes. Is already in, and do you have some more info about it?

Sure.  So it was integrated a couple Betas ago and that's why it's not there.


The Beta I linked to is a culmination of the testing/feedback from these two threads:


The second thread builds on the first - and additional addresses some specific roaming bugs.

Hi @UBNT-Brandon Can you or anyone else answer this for me? I am very interested in ZHO or something similar. I'm about to buy a Pixel Phone with Project Fi service and wanted to know if a setup with 3 UAP-AC-LR devices is going to let me change between APs without dropping my call. Of course i can turn off WiFi, use the cell towers and not worry about it, but that would be silly to suggest i do each time i want to make a call while at home and then try and remember to turn it back on so i don't use my data for other things. Is this a case where i want to use this beta, or will my calls be ok without some sort of ZHO or fast roaming? Thanks, Travis

@krazie Fast roaming for Gen2 products (UAP-AC-LITE, UAP-AC-LR, UAP-AC-PRO, UAP-AC-EDU, UAP-AC-IW, UAP-AC-M, UAP-AC-M-PRO) was released last week.


This should be sufficient for what you'd need - the roaming is fast and VoIP calls don't seem to miss a beat.


This is a big upgrade over ZHO because this fast-roaming does not come with a reduction in performance.

Is fast roaming activated per default after upgrading the devices or do I have to create a new WLAN Group and activate ZH?

(I'm trying to get rid of the iPhone6(s) connection issues (phone connected but no WIFI throughput))
