Internet & Wi-Fi Help

Before contacting Horizon Support, follow the self-support steps below. These checks can resolve many common internet and Wi-Fi issues and help us troubleshoot faster if you still need help.

No Internet Connection

If none of your devices can reach the internet, start by checking the equipment providing your Horizon connection.

1

Try more than one device

Try another phone, tablet, computer, or streaming device. If only one device is having trouble, your Horizon connection may still be working normally.
2

Check that your equipment has power

Make sure your Horizon airCube and other indoor Horizon equipment are plugged in and receiving power.
3

Check the visible cables

Look for a cable that has accidentally been unplugged or pulled loose. Do not move cables between ports unless you know where they belong or are following Horizon's reconnect instructions.
4

Reboot your equipment

A normal power-cycle can resolve temporary problems. Follow the reboot instructions below rather than pressing any Reset buttons.
5

Still offline? Contact Horizon

If multiple devices remain offline after your equipment has restarted, contact Horizon Support so we can investigate.

Slow Internet or Buffering

Slow performance does not always mean the Horizon connection itself is slow. Wi-Fi conditions, device limitations, and background usage can all affect what you experience.

Try another device

If one device is slow but others work normally, the issue may be with that device rather than your internet connection.

Move closer to the airCube

Walls, floors, appliances, and distance can reduce Wi-Fi performance even when your Horizon connection is working normally.

Use Ethernet when possible

A wired test removes most Wi-Fi variables and gives a better picture of the connection reaching your location.

Run a proper speed test

Pause large downloads, cloud backups, streaming, and other heavy internet use before testing whenever possible.

Wi-Fi Help

Every Horizon internet customer has a Horizon airCube-AC. The airCube provides the Wi-Fi network used by your phones, TVs, computers, tablets, and other wireless devices.

Keep the airCube in the open

Avoid placing it inside cabinets, behind large electronics, on the floor, or surrounded by metal objects.

Distance matters

Wi-Fi becomes weaker as you move farther from the airCube and as the signal passes through walls, floors, and other obstacles.

Test near the airCube

If performance improves significantly nearby, you're likely dealing with Wi-Fi coverage rather than a problem with the Horizon connection itself.

Every Horizon Internet Customer

Horizon airCube-AC

The Ubiquiti airCube-AC is Horizon's standard Wi-Fi router and is part of every Horizon internet connection. It creates your Horizon Wi-Fi network and connects your devices to the Horizon network.

If you prefer to use your own router or Wi-Fi system, it still connects through the Horizon airCube.

If your airCube does not appear to be working

1

Check the power connection

Make sure the round power connector is firmly connected to the back of the airCube and its power supply is plugged into a working outlet.
2

Check the WAN cable

The Ethernet cable carrying your Horizon connection should be plugged into the blue WAN port on the back of the airCube. On standardized Horizon installations, this cable may be blue.
3

Power-cycle the airCube

Unplug the airCube's power, wait approximately 30 seconds, reconnect power, and allow a few minutes for Wi-Fi and your devices to reconnect.
4

Check another device

Try connecting another phone, computer, or streaming device before assuming the internet connection itself is down.

Identify Your Horizon Equipment

Every customer has a Horizon airCube, but the equipment feeding the airCube depends on how Horizon service reaches your location.

Example Horizon airMAX fixed wireless receiver

LiteBeam / PowerBeam style
Example Horizon Wave fixed wireless receiver
Wave Receiver
Wave family equipment

Your outdoor Horizon receiver may look different depending on your service area and installation.

Fixed Wireless Customers

Outdoor Horizon Receiver

Fixed-wireless customers have an outdoor receiver installed and aligned by Horizon. It connects your location to Horizon's wireless network.

Depending on your installation, the receiver may be an airMAX LiteBeam 5AC, airMAX PowerBeam 5AC, Wave Long-Range, Wave Pico, or Wave Nano.

Do not move, aim, disconnect, reset, or modify the outdoor receiver unless Horizon Support specifically instructs you to do so.

PoE Power Adapter

Your outdoor Horizon receiver receives power from an indoor PoE power adapter. The adapter also carries the network connection between the outdoor receiver and your airCube.

The black cable coming from the outdoor receiver connects to the PoE side of this adapter. A separate Ethernet cable connects the adapter's network or LAN side to the blue WAN port on the Horizon airCube.

On newer standardized Horizon installations, the cable between the PoE adapter and the airCube WAN port is blue.

ScreenBeam MoCA Adapter

Customers in Horizon-served multi-dwelling unit (MDU) properties use a ScreenBeam MoCA adapter. It uses the property's coaxial wiring to provide the network connection feeding your Horizon airCube.

The ScreenBeam connects by Ethernet to the blue WAN port on the airCube. The airCube then provides Wi-Fi and Ethernet connectivity for your devices.

Did Something Get Unplugged or Moved?

If indoor equipment was unplugged during cleaning, moving furniture, a power outage, or another interruption, use the connection guide that matches your Horizon service.

Fixed Wireless

1

Outdoor cable to PoE adapter

The black Ethernet cable coming from your outdoor Horizon receiver connects to the port on the PoE adapter marked for PoE or the outdoor device.
2

PoE adapter to airCube

The other Ethernet port on the PoE adapter connects to the blue WAN port on the airCube. On standardized Horizon installations, this cable is blue.
3

Connect power

Make sure both the PoE adapter and airCube power supplies are connected to working electrical outlets.
4

Allow time to reconnect

After power is restored, allow several minutes for the outdoor receiver and airCube to reconnect before testing your internet service.

MDU Service

1

Check the coax connection

The coaxial cable serving your unit should be securely connected to the ScreenBeam MoCA adapter.
2

ScreenBeam to airCube

The Ethernet cable from the ScreenBeam connects to the blue WAN port on the Horizon airCube.
3

Connect power

Make sure both the ScreenBeam and airCube are connected to power.
4

Allow time to reconnect

Give both devices a few minutes to start, reconnect, and restore Wi-Fi before testing service.
Do not factory reset Horizon-managed equipment.

Resetting or altering Horizon-managed equipment can remove required configuration and may require an on-site service visit to restore service. Applicable service charges may apply.

Safely Reboot Your Equipment

A normal power-cycle can resolve temporary connection problems. Rebooting means disconnecting power and reconnecting it — not pressing a Reset button.

1

Disconnect power

Unplug power from the Horizon equipment providing your connection and from the airCube.
2

Wait about 30 seconds

Give the equipment time to fully power down.
3

Restore the Horizon connection first

Restore power to the PoE adapter or ScreenBeam first and give the connection equipment a few minutes to come online.
4

Restore the airCube

Reconnect power to the airCube and allow your Wi-Fi network and devices time to reconnect.
5

Test more than one device

Try loading a website or service from more than one connected device.

Get a Better Speed Test Result

For the most useful result, test from a wired device whenever possible. If you test over Wi-Fi, stay close to your airCube and temporarily pause other heavy internet activity.

Open Speed Test
Use Ethernet when possible
Pause downloads and cloud backups
Stop streaming on other devices
Test close to the airCube if using Wi-Fi
Run more than one test if needed

Still having trouble?

If your connection is still not working after these checks, contact Horizon Support. Let us know what you're experiencing, whether multiple devices are affected, and what troubleshooting you've already tried.
