Optus 5G Home Internet vs the NBN modem

Optus 5G Home Internet uses the Optus Ultra WiFi 5G modem – a Wi-Fi 7 device with a built-in LCD screen that shows signal strength, connection type and data usage. It connects over Optus’s 5G network, so there’s no NBN box or phone-line cabling. Placement near a window matters.

Setting up the Optus 5G modem – step by step

  1. Place the modem near a window or up high for the strongest 5G signal.
  2. Plug in power and switch on – the LCD shows it searching for signal.
  3. Activate the service in the My Optus app.
  4. Check the LCD signal bars – try a few window spots and keep the strongest.
  5. Connect your devices to the Wi-Fi using the details on the base label.

Getting the best 5G speed

5G speed depends almost entirely on signal. If it’s slow or dropping, move the modem higher and closer to a window facing the nearest tower – the LCD signal bars guide you. We can find the strongest spot, set it up, and add mesh Wi-Fi if the best-signal corner isn’t where you need coverage.

Common Optus 5G modem problems we fix

  • Weak 5G signal or slow speeds
  • Modem won’t activate
  • Best placement near a window
  • Drops out intermittently
  • Wi-Fi coverage from the signal spot
  • Moving from NBN to 5G Home Internet

The Ultra WiFi 5G modem’s on-screen signal bars are your guide — position it for the strongest reading first, then extend coverage with mesh if the best-signal corner isn’t where you use Wi-Fi.
