Who do I call to fix my NBN in Sydney?
In today’s digital world, a reliable internet connection is just as important as electricity and water. Whether you’re working from home, attending online classes, streaming your favourite shows, gaming, or running a business, your NBN connection plays a vital role in keeping everything connected.
However, when your internet suddenly slows down, keeps dropping out, or stops working altogether, it can be difficult to know who to call. Should you contact your internet provider? Is it an NBN network issue? Or do you need a professional data cabling technician?
If you’ve been searching for “Who do I call to fix my NBN in Sydney?”, you’re not alone. It’s one of the most common questions Sydney homeowners and business owners ask when experiencing internet problems.
In this guide, we’ll explain who is responsible for different types of NBN faults, the most common causes of connection issues, and when it’s time to call a licensed data cabling professional.
Why your NBN might not be working properly
Not every internet problem is caused by the NBN network itself. In many cases, the issue is actually inside your home or business.
Some of the most common causes include:
- Damaged Ethernet or data cables
- Faulty NBN wall outlets
- Loose cable connections
- Poor Wi-Fi coverage
- Incorrect modem or router placement
- Outdated internal telephone cabling
- Faulty networking equipment
- Power interruptions
- Local NBN outages
- Internet provider service issues
Understanding where the fault is located is the first step towards getting your connection back up and running.
Who is responsible for fixing your NBN?
Depending on the type of problem you’re experiencing, different people may be responsible for resolving it.
1. Contact your internet service provider first
If your internet suddenly stops working, your internet service provider (ISP) should always be your first point of contact.
Your provider can remotely test your connection and determine whether the issue is related to:
- NBN outages
- Account or billing issues
- Network congestion
- Service activation
- Speed profile problems
- External line faults
If necessary, they can lodge a fault with NBN Co on your behalf.
2. NBN network faults
Some problems occur outside your property and can only be repaired by NBN technicians.
These may include:
- Damaged street cables
- Fibre network faults
- Damaged pits or pipes
- Faulty nodes
- External line damage
- Area-wide outages
These repairs are organised through your internet provider.
3. Internal cabling and home network issues
This is where many homeowners get caught out.
If your provider confirms the NBN network is working correctly but you’re still experiencing problems, the issue is often inside your property.
A licensed data cabling technician can diagnose and repair:
- Faulty Ethernet cabling
- Damaged data points
- Internal network faults
- Poor Wi-Fi coverage
- Faulty RJ45 outlets
- Modem relocation
- Network cabinet issues
- Home office connections
- Additional data outlets
- Structured cabling systems
In many Sydney homes, internal cabling is the hidden cause of poor internet performance.
Signs you may need a professional data cabling technician
It’s time to call a professional if you notice any of these issues:
- Your internet keeps dropping out every day.
- Certain rooms have very weak Wi-Fi.
- Ethernet ports have stopped working.
- Internet speeds are much slower than your plan.
- Video calls regularly freeze or disconnect.
- Streaming services constantly buffer.
- Your modem frequently loses connection.
- You recently renovated your home.
- You’ve moved into an older property.
- You want better internet throughout the house.
These issues often require on-site testing and professional diagnosis.

Every property is different, but these are some of the most common issues technicians see across Sydney.
1. Slow internet speeds
Slow speeds may be caused by:

Many people assume upgrading their internet plan will automatically solve connection problems.

What you should check before calling for repairs
Before arranging a service visit, there are a few simple checks you can perform.
