Move AP's to new controller

Категория: UniFi

I know this is a beaten question but everytime I start reading all the previous posts on this subject I become more confused :-) so here's what I got.


I’m looking at migrating our Unifi Controller 5.5.20 to another server. I found this great “How To” https://help.ubnt.com/hc/en-us/articles/115002869188input_string=migration+now+connected+%28migrated%29

but have some questions before I do this.


  1. I have three sites on three different subnets in physically different buildings/locations. I take it I will follow the instructions for all three sites, exporting, importing, and forgetting, then on to the next site. Will being on different subnets be a problem?
  2. On the new controller, should I restore the actual controller backup before I start importing sites? I want as little data brought over from the old controller, just configuration settings.
  3. I do have a DNS entry for “unfi” which points to the old controllers IP address. Should I change this to point to the new controllers IP address before I start the migration or after. I’m assuming I want to do this before because in step 8 it asks to put in the URL for the new controller and if I have the DNS already changed I can put in http://unifi for the URL leaving the :8080 and /inform fields alone. Unfortunately it looks like the “set-inform” was configured to the IP address of the old controller and not the “unfi” DNS entry.

Note that I cannot keep the same IP address for the controller. The server that hosts the old controller has other services running on it. 


Thanks for your input

Guest Portal with DHCP for In-Wall AC

Категория: UniFi

I hope to deploy dozens of In-Wall AC units and am looking for an internal DHCP controller so guests are on a separate network.  Many of the AirMax products such as Nanostation and others offered this capability.  But I can't find it using UnitFi controller V5.5.20.  Did UBNT remove this nice feature in UniFi? I wish In-Wall AC had a SOHO router mode.  If no DHCP for In-Wall AC, I'll have to use another vendor.

AP cannot be configured

Категория: UniFi

Hi everyone!


I'm facing  a  strange symptom almost every day with one of my  4 APs (AP AC PRO):

I have the controller software running on a  cloud key.  Everything works fine but if I oen the controller software I  see 1 LAN device (my switch) and for WLAN devices (my 4 APs) in the upper right corner. However in the lower left corner it says  4 devices (1 LAN, 3 WLAN).

clicking on devices, I get the information that all 5 devices are connected, but the order is a bit different from usual. This morning "WLAN-KG" was on top of the list.  I clicked on  this device and  got an empty window on the right. Now chance to configure anything. It works for  the other 4 devices. Checking with my iPhone, the  AP WLAN-KG gives  me full wifi connection. In the topology chart this AP is marked with a "?".  Checking with  the iOS app, I was able to configure this AP normally.  After restart  of the AP (that works  using  the controller software) everything was fine again. Yesterday I had the same problem with another AP.


Is there  a software bug (cloud keay, controller, AP)?

Need help choosing a solution

Категория: UniFi

Current setup consists of an ASUS RT-AC66U in the basement near the cable modem. Up until recently it has worked decently, mainly because my computer was in the living room above the area where the router was, maybe 20-30 feet distant with one floor in the way. I could get 140-150 MBPS there.

Unfortunately, I relocated my desk to the play room. 50-60 feet from the router with th same floor in the way. Now 5G connectivity is useless. I connect, but get 3-5 MBPS on 5G. On 2.4G, I can get 30-40MBPS. This isn't terrible, but doesn't exceed the speed of my ISP. So a solution is needed.

I initially looked into the UniFi AP lineup. Unforunately, these only seem to work when mounted the ceiling. This would work, but I have a wall panel with Cat6 wiring just waiting to be used, so that got me looking at the in-wall units. My primary concern there is rang. They're designed to cover one room well, but I'm hoping they can do slightly more. Can anyone tell me what the coverage pattern is from one of these? IE, do they cover back from the mounting hole, backward behind the unit? Or do the primarily broadcast into the room of the wall that they're mounted on.


Any help in choosing a solution would be helpful.

Server taking too long to start

Категория: UniFi

Just got the Unifi UAP-AC-HD and am having trouble with the controller starting.


I downloaded the latest Unifi controller software (5.5.20).


I am running this on a mac...OS Sierra (10.12.6)


As per a lot of posts here the controller will not startup.  The UI shows this:

Initializing UniFi Controller ...

Start-up failed.


The server.log shows this:

The mongod.log is quite long however does not appear to have any obvious errors.


As per other posts I have tried downgrading to java 6.  This did not make any difference.


At a bit of a loss here so any help appreciated.

Managing remote Unifi AP via Single CloudKey

Категория: UniFi

Hi There


I just want to make sure that I fully understand this before I go and action it.


I am admining 3 remote site - all have different IPs and on each site - there are 2 APs


Site 1 - 2 APs + CloudKey

Site 2 - 2 APs - Dynamic IP

Site 3 - 2 APs - Dynamic IP


Each site has a different purpose and are all set up different 


I am wishing to admin the APs via the single CK. The CK at Site 1 works well and is allowing me to control the APs at Site 1.


If I am wishing to admin Site 2 and Site 3 APs via the Same CK....


Am I correct in thinking, I would just need to go back to Site 2 and Site 3 and do the "set-inform" function via SSH and point the APs to the CK IP Address??


Once they have been "set-inform" then I would simply log into the CK and adopt them from there?


Does it matter if the remote sites have a Dynamic IP?

I am in the process of setting the CK to a static IP (dyndns etc)


I just want to make sure that I am on the correct path before heading out to do this - as the sites are located some distance from each other.


Thanks for your guidance

UAP-AC-HD not getting 1300

Категория: UniFi



So i just installed my first UAP-AC-HD but i am a bit bummed im guessing i need to purchase 1 to 2 more because i cant seem to get 1300MBPS on this thing. I read through some of the forum switched channels that seemed to help but cant get past 878MBPS on my macbook pro. Its a 2013 and i know it will hit 1300MBPS i was able to get it on SOHO routers before. Any insight on what/how i should configure the radios to get best results? I am using VHT160 and channel 48 right now. I put some screen shots below.

Java crashes when using Unifi

Категория: UniFi

I've been having problems getting my Unifi to open in Windows 7 and finally found a crash report that Java crashes each time I try to open Unifi.

I sent the crash report to Java and they tell me that it is a Unifi problem. They said:

"It's a problem with Ubiquiti so you need to ask the people who wrote it for help and troubleshoot the problem. Java is being used to load their .dll libraries via JNI, so the windows libraries that they provided are causing java to crash. The Ubiquiti libraries need to be debugged. Java is just crashing because they misbehaved"


Below is part of the crash report. The full log is attached.


Maybe someone can comment on this and tell me what I need to do.

By the way, I can get into the Unifi controller if I'm in Safe Mode.
