Frequently Asked Questions

Do I need to have a full UniFi topology with a UniFi Security Gateway, UniFi Switch, and UniFi Access Point or can I use a third-party device?

No, you do not need the full UniFi topology in order to use the UniFi Network Controller. Just keep in mind that when you use third-party devices, you not only lose the centralized management system that the Controller provides, you will also be missing features that are available to configure in the Controller. See the Feature Matrix in our basic setup article to learn what each type of device brings to the table. A typical topology might look like this: beginner2.png 

What is the difference between UniFi AP models?

UniFi Access Point (UAP) models might have different radio rates, number of ports, number of concurrently connected clients, among others. To see any devices' full characteristics list, go to their Datasheet or Quick Start Guide, and check out the Specifications section. These documents will always be found at the bottom of the product page, which can be accessed when navigating from the Ubiquiti Products page. They can also be downloaded from our Downloads page.  See our UniFi - Access Point Comparison Charts article for a consolidated view.

How many access points will I need to cover my office?

Users have reported needing only one UAP for average-sized offices, but of course, all offices will have different needs depending on size, building material, wall distribution, number of floors, environment, among others. Use the comparison charts for UAPs and the device's Datasheets to select an AP that is enough to meet your needs. You can always start with the minimum number of UAPs, and add another if necessary. The UniFi Network Controller allows for easy adoption and scalability. You can conduct a wireless site survey to get a true idea of the different areas of signal strength in the building. Another tool that is useful to spot the need for extra access points is the Map feature. Find information about the Map feature and how to use it in the UniFi User Guide, Chapter 6: Map.

Where is the UniFi Network Controller hosted? Do I need to pay for a Cloud solution?

All our software is free, as well as all upgrades. You do not need to pay if you host the UniFi Network Controller software yourself. The Controller can be hosted on any of the following:
  • A dedicated network device such as a UniFi Cloud Key or UniFi Application Server
  • A local server running Linux, macOS 10.11 (or above), or Microsoft Windows 7/8/10
  • A remote server running Linux, macOS X 10.11 (or above), or Microsoft Windows 7/8/10

Only one instance of the UniFi Network Controller is required, even for multiple sites. For example, use either the UniFi Cloud Key or a local server, not both. A UniFi Cloud Key can be used as a remote controller. If you have a number of branch offices/teleworkers that each requires UniFi devices then Layer-3 adoption is required. For more on Layer-3 adoption, see this article: UniFi - Device Adoption Methods for Remote UniFi Controllers. 

What is Hybrid Cloud?

A hybrid cloud deployment allows for a mixture of on-premise and cloud hosted controller deployments. Being able to administrate networks from offsite using the UniFi Cloud Access Portal allows users to manage UniFi networks from any location with an internet connection. For reference on how to enable remote access on controllers please see this article.

I have my UniFi devices and I'm ready to go. Where do I start?

Follow the Quick Start Guide that came with your device to set up the hardware as well as the UniFi Network Controller software. You can also find the QSGs in our Downloads page, using the left hand menu to navigate to your device model and then find the QSG under the Documentation header. The next step will be to get familiar with the Controller. The UniFi User Guide has all the information you need to get up and running and to perform your first configurations. This basic, first setup article might also be helpful.


If you run into any issues remember you can search our Help Center for help articles and you can reach out to all the user experts in the Community.

Do I need to install and host software (UniFi Network Controller) to use UniFi? I just want to plug my UAPs and enjoy my WiFi.

No, not necessarily. If you only want to set up one or a few UniFi Access Points (UAP's) and don't want to install (and host) the UniFi Network Controller, you could use the UniFi mobile app's Standalone mode. You can also include a UniFi Switch if you want to use it to power the UAPs, but you will lose any possibility of configuration on the switch. You'll find the UniFi app for Android and iOS, available for free on the App Store and Google Play. With the Standalone mode you will not need to install the UniFi Network Controller and have it running on a server, computer, Cloud Key or UniFi Application Server. The downside is you will not be able to take advantage of all the (free!) features included in the Controller. You can read all about Standalone Mode here

My password isn't working. What is the default username and password for UniFi devices?

The UniFi products in their factory-default state can have two possible default username / password combinations, remember both password and username are case-sensitive:

Username: root

Password: ubnt

Username: ubnt

Password: ubnt

It is important to note that there are several different sets of credentials you will create when using UniFi. Do not confuse the UniFi Device Authentication credentials with the UniFi Cloud Access Portal credentials, the UniFi Network Controller credentials or the UniFi Cloud Key and SSH credentials. Read more about that here.

What Java / JRE version should I be using?

NOTE: Currently, any version newer than Java version 8 is incompatible with the UniFi Network Controller.

UniFi 5.12.35 Stable: Only Java 8 is supported.

UniFi 5.6.40 LTS Stable: Java 8 is supported.

Do I need an account to get started? How do I create a Ubiquiti account?

The Ubiquiti SSO Cloud username and password are the Single Sign-On, UI.com account credentials created in https://account.ui.com/. This set of credentials is used in the UI Community, the UI Store, and the UniFi Cloud Access Portal. See this article to learn how to create your Ubiquiti SSO account.
