Connectivity Problems and 5GHz Radio - UAP-AC-Pro, UAP-AC-LR, and UAP-AC-LITE

[ Edited ]

Hi UniFi Users,

 

As the Gen2 line (UAP-AC-Pro, UAP-AC-LR, and UAP-AC-LITE) is used in wider and wider breadths of installs, we're starting to find and fix issues we haven't seen (and often can't repeat) in our test labs (despite have over 500 connected devices in one test lab alone).

 

We are continuing to release new GAs of the UniFi Controller to address these - but given the GA process for the controller involves much more QA than a FW - and some of you might want to run the latest hotfixes with a custom upgrade from your current controller, we wanted to make this location as the central place to find the 'latest' with regards to fixing the issues being discovered.

 

With that, here is the latest FW for UAP-AC-Pro, UAP-AC-LR, and UAP-AC-LITE:

(Updated as of 22 Jul 2016)

LTS controller: http://dl.ubnt-ut.com/uap-ac-pro-3.4.x-rates2.bin

5.x controller: http://dl.ubnt-ut.com/uap2-develop.4649.bin

 

Changelog 19 May 2016:

  1. Improved 2.4GHz rate selection and retry algorithms.
  2. Fixed 5GHz radio lockup under heavy use and high user count.
  3. Improved 5GHz rate selection and speed.

Stability Changelog 22 Jul 2016:

  1. Fix more rate control issues, specifically for pre-11n stations in 2.4 GHz.
  2. Fix potential 5-30 minute packet loss on 5 GHz radio.

We'll post new comments on this thread for each new FW we have (so those subscribed will get an email).  And will edit the link above to be the latest when we post (so you can look no further than above to find the latest).

 

Thanks,

Brandon

Hi again UniFi Users,

 

We've integrated these fixes into 5.0.6 RC, here:

http://community.ubnt.com/t5/UniFi-Beta-Blog/UniFi-5-0-6-RC-is-released-for-testing/ba-p/1578544

 

This RC will likely be what goes to GA on June 1st.

 

We will soon also be releasing a 4.8.X RC which will incorporate these fixes.

 

Thanks,

Brandon
