Unifi Configuration Tutorial

Basic Connectivity:  

Router (Broadband/mikrotik |dhcp enabled) >>> Unifi + LAPTOP

Unifi (Powered ON) [POE port] >>>> LAPTOP [LAN port]

Step1: Open Unifi controller in the browser.

Step2: Open a site in the name of that client and keep the tab open.

Step3: Open unifi discovery tool.

Step4: Any newly connected (which is still unadopted) unifi device will appear in this tool.

Note: In discovery tool,we will get three options to use.

Primarily we will use manage and input url (https://unifi.domain.com:8080/inform) and apply.

Step5: We will notice the communication between discovery tool and unifi controller in the controller. 

 .

Step6: We will notice the communication between discovery tool and unifi controller in the controller. 

Step7: We will notice that the unifi device is appreared in the controller (In our created site) and waiting for our adoption.

Step8: We will adopt the device in the controller. Then the device will disappear from the controller and will permanently add to our controller.

Step9: Then we will upgrade the firmware of the device from the controller.

Step10: Now the device is upgraded and properly connected to the controller. It is also ready for the further configuration.

Step11: We will begin configuration of the device as per our requirement.

Note: As we are now on the site page. And the device is also adopted. By clicking settings on the bottom left corner, we will enter the setting for further input.

Step12: We will begin configuration of the device as per our requirement.

Note: With this user name and password anyone can login to the device directly (manually).

Step13: We put ssid and password in the Wireless Netowrks section.

Step13: We fill up LAN section configuration as per our need.

Note: Normally the dhcp server of the device should be disabled. But if we need to use dhcp server mechanism from the unifi AP then we will enable the dhcp server settings.

 

Step14: Configuration is complete. We can restart the device from the controller and check whether it is broadcasting the configured SSID or not. Also, we will check whether we can connect to the SSID with the give password.

Exceptional Case

In case of exception, we may face trouble to discover the unifi at the very beginning of our process in steps4. Sometimes, we may discover the device but unable to adopt it in the controller. For that situation, we will follow below steps:

Problem: Unable to discover the device in the discovery tool.

Solution: Reset the device. Try manual configuration by connecting the device directly to the laptop. And will follow this.

1. Reset the device.

2. Put a 192.168.1.x/24 series IP in the laptop

3. Ping default IP (192.168.1.20) of unifi to check device’s availability.

4. telnet the ip from putty. 

5. Use default login credentials:

1. User:ubnt

2. Pass:ubnt

6. After logging press help for further command help

1. #help [To get the command list]

7. We will find below commands. We will use them as per our need.

BZ.v3.2.1#info [It will show necessary information of that device]

BZ.v3.2.1#set-defaults [restore to factory default] [It will soft reset the device.]

BZ.v3.2.1#set-inform https://unifi.domain.com:8080/inform/ [It will try to communicate with the controller. We may need to repeat the process several times to successfully execute the command.]

BZ.v3.2.1#upgrade <firmware_url> [copy devices latest firmware address from the UBNT website. And upgrade the firmware]

Example: upgrade http://dl.ubnt.com/unifi/firmware/U7HD/3.9.3.7537/BZ.ipq806x.v3.9.3.7537.171013.1055.bin

BZ.v3.2.1

BZ.v3.2.1#reboot

Additional Troubleshooting commands:

                      set-inform http://unifi.domain.com:8080/inform

                      syswrapper.sh restore-default

If the process succeeded then by connecting the device to router it make it get an IP from the router. It will also appear in the discovery tool as well as our created site. We will be able to successfully adopt the device in the controller by using above mentioned process.

8. In some case, we may discover the device at discovery tool, but unable to adopt it in the controller. Then we will perform hard reset and telnet the dhcp IP it is getting from the router. 

After logging in the device, we will perform steps mentioned in above exceptional case scenario.

9. In some rare cases, we may find every attempt of reset and adoption of the device failed. Then we need to flush the device’s existing firmware and upload a new firmware using TFTP software tool.
