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.
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 Any damaged or outdated cables/line filters should be replaced.
(Optional) 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 Westnet modem settings into "safe mode" (G.DMT mode). Note: 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.
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.
