What is Wireless Broadband?

Wireless Broadband runs over One NZ's mobile network, using the same technology your mobile phone uses to access the internet.
There’s no physical cable connection; instead, your modem connects wirelessly to the nearest cell tower to deliver connectivity to your home.

Set up your Wireless Broadband modem

The Huawei B818 4G wireless modem.

To set up your new Huawei B818 4G modem, follow these simple steps:


Step 1. Insert the SIM card
If you ordered 4G Broadband online or over the phone, you’d have been sent a SIM card with your new modem. Slide the SIM card into the slot on the bottom of your new modem, and it will click into place when inserted the correct way around. If you bought a 4G modem from one of our stores, the SIM card will already be inserted for you.

Step 2. Power up
Plug your modem into a power plug; the best place for a strong wireless connection is near a window.

Step 3. Connect to 4G
When the light on the front turns from red to blue, you’re connected to our 4G network. It’ll happen pretty quickly. The more bars showing on the modem, the stronger the connection. If needed, move your modem to get better signal strength. Try moving it to a window on the other side of the house or ensuring that it’s not covered by anything.

Step 4. Connect your devices to WiFi
Use the network name (SSID) and password (WiFi Key) on the sticker on the bottom of the modem to connect your devices.

To set up your new Huawei H122 5G modem, follow these simple steps:


Step 1. Insert the SIM card
If you ordered 5G Broadband online or over the phone, you’d have been sent a SIM card with your new modem. Slide the SIM card into the slot on the bottom of your new modem — it will click into place when inserted the correct way around. If you bought a 5G modem from one of our stores, the SIM card will already be inserted for you.

Step 2. Power up
Plug your modem into a power plug; the best place for a strong connection is near a window.

Step 3. Connect to 5G
When the 5G light on the front turns on, you’re connected to our 5G network. A green light means you have a strong connection, a yellow light means moderate and a red light means there’s a weak connection. If needed, move your modem to get better signal strength. Try moving it to a window on the other side of the house or ensuring it’s not covered by anything.

Step 4. Connect your devices to WiFi
Use the WiFi Name and WiFi Password on the sticker on the bottom of the modem to connect your computers and other WiFi connected devices.

Wireless Broadband modem set up FAQs

How do I choose my own Wifi password?

To change the network name and password on a TP-Link Deco modem, follow the below steps:

If you haven’t already, download the TP-Link Deco app and follow the simple in app instructions to finish setting up your new modem and WiFi network – make sure you select the correct modem type in the app.

Note, you may need to unplug the modem and begin the modem setup again.

Download the app here:

Google Play Apple App Store

1. Open the TP-Link Deco app
2. If you have Deco App version 3.0 tap on the WiFi Settings button. If you have an older Deco App tap on the ‘more’ icon on the bottom right of the home screen and select the Wi-Fi button
3. Change the network name (SSID) and password within the app


To change your network name and password on a Huawei modem, follow the below steps:
1. Connect a device to Wifi using the network name (SSID) and password on the bottom of the modem.
2. Open a new browser on this device and enter "192.168.1.1" in the search bar. The login screen will be displayed.
3. Log in using the password on the bottom of the modem, which is printed under the IP address. If you have updated this password previously, then use the password you created.
4. Click on the Wifi Settings tab — the Wifi Basic Settings screen will then appear.
5. Select the Wifi name (SSID) field, click edit and then enter the new name for your Wifi.
6. In the Wifi password section, enter the new password for your Wifi.
7. We recommend that the 5GHz preferred is selected — this means that both the 2.4 and 5Ghz Wifi bands use the same Wifi name and password.
8. Click save at the bottom of the page.

How do I set up my new home phones?

To set up your new home phones, simply:
1. Insert batteries into each phone.
2. Plug the larger base unit into the back of your new modem and into a power plug – no phone jack required.
3. Plug the smaller base unit into any power socket. It's a spare phone for you to have anywhere you’d like in your home.

Remember: To make phone calls, you’ll now need to dial the area code (e.g. 09,09, 03) before dialling the phone number.

How do I set-up my modem if I have SuperWifi?

If you already have the TP-Link Deco app installed from setting up SuperWifi, you will need to reset your network to make the Deco X80-5G or X58-4G the master device:

  1. If you have Deco App version 3.0 tap on the picture of your device, then the 3 dots in the right hand corner and delete the network. If you have an older Deco App tap on the globe icon at the top of the app’s home screen, click the three dots and delete the network.
  2. Your SuperWifi units will then start flashing blue – we recommend unplugging them until it’s time to add them back into your new network.
  3. Follow the in app prompts to set up your new Deco X58-4G or X80-5G modem.
  4. Once your new network is up and running, you can add your SuperWifi units to the network.
