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 http://community.ubnt.com/t5/UniFi-Feature-Requests/Zero-Handoff-on-UAP-AC/idc-p/1628971#M5971

@UBNT-Brandon
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:

http://community.ubnt.com/t5/UniFi-Beta-Blog/FIRMWARE-3-7-21-5389-has-been-released/ba-p/1707596

 

To sign up for Beta, go here:

https://help.ubnt.com/hc/en-us/articles/204908664-How-To-Signup-for-Beta-Access

 

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).

 

Thanks,

Brandon

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:

  1. http://community.ubnt.com/t5/UniFi-Wireless-Beta/802-11k-802-11r-FT-and-802-11v-support-again-sorry/...
  2. http://community.ubnt.com/t5/UniFi-Wireless-Beta/Roaming-Debug-Image/m-p/1682014/highlight/true#M330...

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

 

Cheers,

Brandon

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.

 

Cheers,

Brandon

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))
