Unifi controller setup and guide

Setting up an Unifi Controller is really easy and can be done in a couple of minutes with this beginner’s guide. We are going to walk through the initial setup of the controller, connecting the access points and getting the most performance out of it. (Unifi controller setup and guide)

Also, I will give you some tips on choosing the right Unifi Access Point, where you should place your AP and how to get the most performance out of your Unifi access points.

The great thing about the Unifi range is that you get enterprise-class wifi for an affordable price. What you also will discover is that they are super easy to set up and manage. And if you like statics, you will get some great insights into your network as well.

Which Unifi Access Point should you Choose?

Ubiquiti offers a wide range of Access Points, but in this article, I will focus on the most used access points for home networks and small-medium sized businesses. The HD and EDU lines are for environments where you need to support up to 200 users on a single device.

There is one good reason to use the Nano HD in a home network, you can buy skins for the Nano HD. The NanoHD is pretty small, only 16cm in diameter, so you can place them more easily in plain sight. But if you don’t like the white color, then there are plenty of skins to choose from. (Unifi controller setup and guide)

The most used Access Point at home or at small businesses is the Unifi AC-Lite. The reason is simple, it’s small (only ∅160 mm), cheap and powerful enough. Depending on the layout of your home or office you can better buy two smaller access points then one large one. Walls, floors and other obstacles will lower the signal strength. If you want to know more about it, you should check this article.

There are three options to choose from, the Lite, Long Range (LR) and the Pro.

Unifi AC LR vs PRO

The difference between the lite and the other is obvious, but the difference between the Unifi AC-LR and the Unifi AC-PRO is a bit harder. You might be tempted to buy the faster and more expensive AC-PRO (bigger is better / more antennas is better / more expensive is better ? ). But there is a big and important difference between the two.

The AC-Pro has 3×3 MIMO antennas to get that high network speed, but to use it, your endpoint (notebook, smartphone, tv) must also be able to handle it. So if you are after maximum speed and you have a notebook that also supports 5ghz network at 1300 Mbps, then you should go for the AC-Pro.

The AC-LR has a bigger and more sensitive antenna. This allows it to cover a bigger area, but even more important, picking up the weaker signal from a smartphone or tablet. Mobile devices have only a small antenna built-in it due to the lack of space and aesthetics. So they can receive the signal of a powerful access point, but they can’t send it the same distance back. That why you need a big and sensitive antenna to pick the weak signal up.


Where to place the Access Point

For in-house placements, the AC-Lite or AC-LR are most of the time the best fit. To determine where to place the Access Point you need to keep in mind that the Unifi Access Point has a doughnut shape coverage with the Access Point in the middle.

Also, try to place the Access Point in the room where the wifi is used the most and at least 3 feet away from other appliances that send wireless signals in the same frequency (cordless phones and microwaves for example). Also, large metal objects (fireplaces, chimney) tent to weaken the signal.

Depending on your floor type you will need one for every floor or you can do with just one Access Point on the first floor or ground floor ceiling. If you have wooden floors, you could start with just one Access Point. Place it in a central location without any obstruction for the best coverage. When you have concrete floors, you will need to install an Access Point on every floor for decent coverage. The rebar and concrete weaken the signal too much for good coverage.

Unifi Controller Setup

So we now know what to buy, where to place it, but how do we install and manage it? To manage our access points we are going to install the Unifi Controller. With the Unifi Setup Wizard, it is done in a couple of minutes.

Step 1 – Unpack and Connect

I won’t go into detail too much about the actual placement of the Access Point, the Unifi Access Points come with a perfectly clear installation instruction on how to mount the Access Point.

But before you actually place it, first just connect it to your switch or router with the supplied PoE adapter. This way you can install it, reset it and see what happens more easily than walking upstairs to check the status light all the time 😉

We are going to install the Unifi Controller to manage our access points. Now the Unifi Controller doesn’t have to be running al the time. So you can install it on your computer, configure your Access Points and they will keep working.

Step 2 – Download the Unifi Controller Software


The only disadvantage is that you don’t have all the insights that you get when the controller is running 24/7. Another option is to use the Cloud key, a small device that is bought separately for some dollars,- and that you connect to your network. When connected you can manage your network remotely.

To install and manage the Unifi Access Point we need to download the controller. Go to the download page at ubnt.com and download the latest controller from Windows, Mac or Linux:

Step 3 – Install Unifi Controller

After you installed the software, start the controller and hit Launch a Browser to Manage a Network or go to https://localhost:8443 in your browser. When you get a warning just click Advanced” and Continue to…

Set your timezone

On the next page, Configure devices, you will see the connected Access Points. Select the devices that you want to configure. If there are no discovered devices, but your Access Point is running and the light is glowing white then there is something wrong (obvious). (Unifi controller setup and guide)

Configure Devices

  1. Check your local firewall. If you have any internet protection software running like Norton, Avast or any other firewall software on your computer, open it and disable your firewall to see if you can find the devices.
  2. Download the Ubiquiti Device Discovery Tool from the Chrome App store. With this tool, you can scan your network for Ubiquiti devices. Check if there are on the same network as you are.
  3. Reset the Access Point, hold the reset button for 5 sec to set it back to factory settings.

Configure WiFi

Enter a name for your Wifi network and a strong password. You can change these details later. You can change these details later on. Also adding a guest network can be done later.

Controller Access

The last step is to enter your credentials. You need to enter an admin account for the controller self and also a separate admin account for the devices. This account is used to access a device directly or to adopt the device again when you had to re-install the Unifi Controller.

When done click finish and login in for the first time into the controller. You will see the dashboard with the connected devices.



Optimizing your Access Points

Out of the box, the Unifi Access Points are doing a great job. But with a few small changes, you can get more performance out of it!

Upgrading the firmware

So we are now logged-in the controller and our Access Point is running you first should upgrade the firmware. This contains the latest bug fixes and features for your Access Point. Go to Devices and click on Upgrade on the right side


Uplink Connectivity Monitor

If your controller is not online 24/7 you should turn off the Uplink Connectivity Monitor in Settings – Site. This will make the Access Points work better when the controller is not available.

Bandwidth steering

Bandwidth steering helps dual-band clients, like laptops, mobile phones, tablet etc to use to less-congested and higher capacity, 5 GHz band. This will result in a better WiFi performance for those devices. You can enable and configure bandwidth steering per device in the Unifi Controller.

Go to Site and enable Advanced features under the services section. Then go to devices and select the access point. Under config (on the right side) you will find bandwidth steering. Set it to Prefer 5G.

Disable the wifi on your old router

The last step is to disable the wifi on your old router because the UAP is strong enough to cover your entire house. You can’t just unplug your router, you need it for your internet connection. To disable the wifi on your router, you need to log in to the admin interface of your router (most of the time you will find it on or, find the Wireless settings, and turn it off.
