Troubleshooting ADSL or Naked DSL Speed Issues

Please follow the steps below and proceed to next step if the issue persists.

Step 1) Check network status

  • Visit our Network Status page to see any known issues in your area that may be affecting your service speed.
  • If there are no event notices, proceed to next step.

Step 2) Restart your modem

  • Turn off your modem and leave it off for at least 60 seconds.
  • Turn your modem back on and allow it to reboot (wait for the modem lights to settle into a stable pattern).
  • Run a speed test.

Step 3) Check your WiFi signal and switch to 5GHz WiFi

  • If you're testing your speed on a device connected to your modem via WiFi, stand next to your modem to rule out any WiFi signal issues.
  • Run a speed test.
  • Connect to your modem’s 5GHz WiFi instead of the slower 2.4GHz WiFi network. If your modem has 5GHz WiFi, you’ll find the default 5GHz WiFi name and password on its barcode sticker (example below).
  • If your speed has improved, or slow speeds occur on WiFi devices but not devices connected via Ethernet cable, then see our guide on improving WiFi signals.

Step 4) Check speed on a single device

  • Unplug all other devices connected to your modem's Ethernet ports (except the device you are testing, if applicable).
  • Turn off or disconnect all other devices connected to your modem's WiFi (except the device you are testing, if applicable).
  • On the device you are testing, close all programs that are using your broadband connection.
  • Run a speed test.
  • If your speed has improved on a single device, you may be running more devices/programs than your connection can handle. You may be able to get more bandwidth on an NBN™ plan. Check your address on our website to see if NBN™ is available in your area.

Step 5) Check your cables and line filters

  • Check that all cables connected to your modem are in good condition and plugged in securely, without any kinks.
  • Faulty line filters are common culprits for causing interference on a DSL connection.
  • Any damaged or outdated cables/line filters should be replaced.
  • Run a speed test.

Step 6) Optional: Try Safe Mode

  • Connection stability may affect speed, particularly if you have an off-net ADSL connection or you're a long distance from your local exchange.
  • Follow this guide to change iiNet modem settings into "safe mode" (G.DMT mode).
  • If you have a third-party modem, please consult its user manual or contact the manufacturer for information on how to put it into safe mode.

Step 7) Check antivirus and firewalls

  • Make sure your antivirus/anti-malware software is up to date, and perform a scan on any devices that are running slowly.
  • If any infections are detected, make sure they are quarantined and removed. Please contact your software’s Customer Support if you need assistance.
  • Firewalls may affect broadband performance. Temporarily disable any firewalls and run a speed test.
