Common problems & fixes
My internet isn't working
- Check the lights on the NBN Connection Box (NTD). If they're all off, there's a power issue — check the power adapter and PowerPoint.
- Power-cycle your router. Turn it off at the wall for 30 seconds, then back on. Wait 2 minutes for it to come up.
- Connect a laptop or desktop to the router with an Ethernet cable and try again. If that works, it's a Wi-Fi issue, not an internet issue.
- If still down, call (07) 3188 5115. Have your account number and the NBN Connection Box lights ready.
My Wi-Fi is slow or dropping out
- Run a wired speed test first to see your real service speed. If it's fine, the issue is Wi-Fi-specific.
- Move the router to a central, open location. Avoid placing it inside cabinets or near microwaves.
- Make sure you're on the 5GHz band (faster) rather than 2.4GHz (longer-range but slower) when close to the router.
- If you have a large home, consider upgrading to a mesh-capable router like the Ubiquiti UniFi Dream Router 7 — ask our team about a router upgrade.
My VoIP phone has no dial tone
- Ensure the phone cord is plugged into the FXS port on the back of the router (usually labelled Phone 1 or Line 1).
- Check that your internet service is working — VoIP runs over internet.
- Pick up the handset and wait 5 seconds for the dial tone to come through.
- If still no tone, power-cycle the router. If issue persists, call us.
I can't log in to my customer portal
- Make sure you're using the email address on your account — this is the one we invoice to.
- Use the Forgot Password link to reset. Check your junk/spam folder for the reset email.
- If the reset email doesn't arrive within 5 minutes, your email provider may be blocking our sender. Email us at support@centrefit.com.au for manual help.
My invoice looks wrong
- Compare the invoice line items against your plan's Critical Information Summary.
- Check for any once-off charges (hardware, call-out fees) that might be bundled in.
- If you've added or removed add-ons mid-cycle, the invoice will pro-rate them — this is normal.
- If it still doesn't add up, email accounts@centrefit.com.au with the invoice number and we'll review within 2 business days.
