Telstra 5G Home Internet vs the NBN Smart Modem
Telstra 5G Home Internet uses a dedicated 5G modem that connects over Telstra’s mobile network instead of a fixed NBN line – so there’s no NBN box and no phone-line cabling. Placement matters: 5G modems work best near a window or in an elevated spot with a clear line to the nearest tower.
Setting up the Telstra 5G modem – step by step
- Place the modem near a window or high up, away from thick walls and other electronics.
- Plug in the power and switch it on – let it boot and search for signal.
- Activate the service in the My Telstra app (or follow the included start guide).
- Check the signal indicator – if it’s weak, try a few spots near windows and pick the strongest.
- Connect your devices to the Wi-Fi using the name and password on the modem’s base sticker.
Getting the best 5G speeds
5G performance depends heavily on signal. If speeds are low or dropping, the fix is almost always placement – higher, nearer a window, facing the tower. We can find the strongest spot in your home, set up the modem, and add mesh Wi-Fi if the signal corner isn’t where you need the Wi-Fi.
Devices and exact lights vary by hardware revision – check your modem’s start guide or the My Telstra app, or call us and we’ll walk you through your specific unit.
Common Telstra 5G modem problems we fix
- Weak signal or slow speeds
- Modem won’t activate
- Not sure where to place it for best signal
- Connection drops at certain times of day
- Wi-Fi doesn’t reach where you need it from the window spot
- Transferring from NBN to 5G Home Internet
5G Home Internet speed is almost entirely about signal, so placement is the single biggest lever — higher and nearer a window facing the tower. Where the best-signal spot isn’t where you actually use Wi-Fi, mesh closes the gap.
