Troubleshooting One NZ Issues
Common One NZ connection problems and how to fix them.
One NZ fibre or 5G speeds are below expected performance
Cause: Wi-Fi interference, modem placement, or 5G signal strength can affect speeds.
- Test via ethernet cable directly connected to the modem
- Restart the modem by unplugging for 30 seconds
- For 5G Home Broadband, move the router near a window facing the nearest tower
- Check if other devices are consuming bandwidth
- Contact One NZ support if wired speeds remain below 80% of plan
5G Home Broadband speeds are much lower than expected
Cause: Distance from 5G tower, building materials, or network congestion can reduce wireless speeds.
- Place the 5G router on the highest floor near a window
- Check one.nz for 5G coverage strength at your address
- Avoid placing the router behind thick walls or metal objects
- Consider switching to fibre if available for more consistent speeds
Wi-Fi signal does not reach all rooms in the home
Cause: Single router may not cover multi-story or large floor plan homes.
- Add SmartWiFi mesh units for NZD 5 per month
- Place the main router in a central location
- Use 5 GHz band for faster speeds in nearby rooms
- Use 2.4 GHz band for longer range to distant rooms
