How to Troubleshoot Unifi Internet Problems: A Simple Step-by-Step Guide

If your Unifi Internet is slow or not working, check for an outage first, check your equipment and indicator lights, restart your devices, then use EasyFix before contacting support.

1. Check for an Outage or Maintenance

Before changing your router settings, check whether your area is affected by a Unifi service interruption or maintenance.

Unifi provides Unifi Alerts for service disruptions and affected areas. (Unifi Alerts)

You can also check for a service outage through EasyFix using your relevant service details. (Unifi EasyFix – Service Outage)

If there is a confirmed network issue, changing your home Wi-Fi settings is unlikely to resolve the underlying problem.

2. Check Your Unifi Equipment and Indicator Lights

Before restarting everything, check your Unifi equipment and make sure the power, fibre and Ethernet connections are properly connected.

Unifi's official guidance tells customers to check the equipment indicator lights, including the PON light, and to ensure the PON light is stable and green. A red or flashing indicator can indicate a service disruption. (Unifi System Upgrade FAQ)

Pay particular attention to the LOS (Loss of Signal) indicator.

A flashing red LOS light means the ONT is not receiving optical power or that the fibre connection may not be connected properly. (Unifi Equipment Guide)

A stable green PON light indicates that the ONT has successfully registered with the OLT. (Unifi Equipment Guide)

This does not mean that a PON light being green automatically rules out every other possible issue. It simply tells you that the ONT has established the relevant optical registration.

A quick LED check

PON — stable green

The ONT has successfully registered with the optical network. (Unifi Equipment Guide)

LOS — flashing red

The ONT is not receiving optical power or the fibre connection may not be connected properly. (Unifi Equipment Guide)

If the LOS light remains abnormal after checking the fibre connection and restarting the equipment, move on to EasyFix or report the issue to Unifi.

3. Restart Your Unifi Equipment

Unifi recommends switching off the relevant equipment, waiting 10 seconds, then turning it back on and allowing around 2 minutes for the service to resume. (Unifi Installation Guide)

If your setup includes both an ONT/BTU and a router, follow Unifi's instructions for restarting the equipment.

Restarting is one of the simplest troubleshooting steps and can resolve some connection-related problems.

4. Use Unifi EasyFix

If restarting does not solve the issue, use Unifi EasyFix.

EasyFix can help customers self-diagnose problems involving:

1. Internet connection
2. Internet speed
3. Wi-Fi
4. Telephony
5. Unifi TV

Unifi says EasyFix is available through the Unifi Portal, MyUnifi App or the EasyFix website. (Unifi EasyFix FAQ)

A particularly useful feature is that EasyFix can still be accessed when your home Internet is down, using a mobile phone browser. (Unifi EasyFix FAQ)

5. What If EasyFix Finds a Problem?

This is where EasyFix becomes more useful than simply telling customers to contact support.

If self-troubleshooting does not resolve the problem, Unifi says EasyFix can automatically create a ticket/report or provide access to Live Chat for further assistance. (Unifi Promise)

So you do not necessarily need to start from the beginning and explain the same problem again.

The important distinction is that Unifi's official information confirms automatic ticket/report creation or Live Chat access. It does not state that every diagnostic result automatically triggers a technician visit.

6. When Should You Contact Unifi?

You should contact Unifi when:

1. The problem continues after restarting your equipment
2. The LOS indicator remains abnormal
3. Multiple devices cannot connect
4. Your Internet repeatedly disconnects
5. EasyFix cannot resolve the issue
6. EasyFix creates a report for further assistance

Unifi lists Live Chat, Service Request Form and the TM100 hotline among its support channels, with Live Chat available 24 hours a day. (Unifi Contact Us)

NetBijak's Take

Unifi's official troubleshooting flow is straightforward:

Check outage → Check equipment and LED lights → Restart → EasyFix → Contact Support

The LOS and PON lights are useful first-level clues, especially when you want to determine whether the problem may involve the fibre connection itself. They are indicators, not a complete diagnosis. (Unifi Equipment Guide)

Most importantly, do not assume that a slow connection means you need a faster broadband plan.

Troubleshoot the connection first, use Unifi's diagnostic tools, and only consider upgrading when your actual usage or broadband capacity justifies it.

Troubleshoot first. Upgrade second.
