Internet technician in Blacktown, for fibre that arrived and still drops out.

Sound familiar?

The NBN has been and gone in Blacktown, and the connection still isn’t steady?

Drop-outs are the commonest thing Blacktown fault callers describe, and four in ten had already had a technician round.

We work for you, not the provider or NBN. A single visit checks from the street to your devices, fixes your side where it can, and puts the rest in writing for whoever owns it.

1. Plug a laptop straight into the router with a cable. Run a speed test while the problem is happening. Fast on the cable and slow on wifi: it is the wifi, and the WiFi Technician page is the one you want. Slow, or dropping out, on the cable too: keep reading, it is the connection.
2. Look at the lights on the box on the wall. The NBN box, sometimes called the NTD, tells you which part of the connection is alive. Only the power light on is not a wiring problem in the house. What the lights on the NBN box mean explains each one.
3. Reset the box and the router properly, once. Hold the reset on the box until every light flashes, then let it come back. Router off for thirty seconds, then on; if it was ever factory reset, it needs its settings put back before it will connect.
4. Ask next door. If the neighbours are down too, it is the street, not your house, and nothing inside will fix it. Ring your provider and wait for them.
5. If your provider says it is your wiring, ask for that in writing. Then ring us. If our testing shows the fault is not in your house, the full escalation report is what you send them.
6. In a unit, ask your provider for your cable pair details first. They save an hour at the MDF, the frame in the basement where the street cables meet the building’s, and they tell us which pair is yours.
7. If an NBN technician is already booked, let them come first. They test to the boundary at no charge. If they say it is not theirs, that is when to book us.

Drops, dead lines, damaged cable and the flat out the back: Blacktown faults

The usual suspects

Where Blacktown faults come from, in the house and out the back

Fibre has reached more of Blacktown than most places we hear from. It often moves the trouble rather than ending it: everything after the box is the cabling and wifi that were already there.

• The cabling after the NBN box.

  Fibre stops at the box; the cable to the modem and the wifi are the old ones.

  Fibre to the premises is 23 of the 55 Blacktown connections we know, and 7 of the 9 since 2024. Everything after the box is the house’s own, and that’s where a fibre fault often lives: a tired cable to the modem, the modem in a corner, wifi that doesn’t reach. It’s tested from the box outward.

• Joints and extensions on copper.

  On fibre to the node or the curb, every joint and old socket on the line matters.

  Fibre to the node and the curb together are 17 of the 55 Blacktown connections we know. Their last stretch is copper, where a corroded joint or an extension left from the landline days causes drop-outs that run for months. Each one is found and taken off the line.

• A blocked or broken conduit.

  An old conduit from the street that won't take a cable, or one broken in the yard.

  The cable from the street leads the Blacktown list, 24 of 111 enquiries. Sometimes the cable is fine and the conduit is the problem, as in the Schofields call, where an NBN technician had found it blocked. On the property’s side it’s cleared or replaced, quoted first.

• Getting the flat connected.

  A flat with no service, or a cable to it that was never finished.

  Granny flats come up in 25 of the 86 Blacktown enquiries with a known property, the highest share we see. The flat is fed by a cable from the house or given its own connection, and what’s already buried between them decides the cost.

• The isolator outside, on HFC.

  On the cable network, the isolator and fittings where the coax reaches the house.

  Read moreShow less

  HFC is 11 of the 55 Blacktown connections we know. The coax finishes at an isolator in a box on the outside wall; a surge or corrosion there causes faults that come and go. With the house disconnected, a reading at that box sorts the street from the house.

• The modem and where it sits.

  A modem on the wrong port, its settings lost, or tucked in a far corner.

  Of the Blacktown calls that pointed one way, 26 pointed inside the property and 10 to the network. Inside often means the modem: the wrong port, lost settings, or a spot the wifi can’t escape from. A laptop on a cable to the box proves whether it’s the modem.

• A wired connection where wifi won’t do.

  A room, an office or the flat that needs a cable, not a stronger signal.

  Fifteen Blacktown enquiries were for data cabling. Where the wifi can’t reach a room or a building reliably, a cable run is the fix, quoted through the data cabling page.

• Patch leads and business cabling.

  In a business, a tired patch lead, or indoor cable run where it shouldn't be.

  Eleven of the 86 Blacktown properties we can place are businesses. Their faults can sit in the building’s own cabling, as at the Seven Hills factory complex in the video below, where indoor-grade cable ran underground and a patch lead was dragging the speed down.

How it works

Box to modem to flat: a Blacktown visit in four steps

You get the answer in writing at the end. Testing stops at the network boundary, since the network past it is NBN’s and we work for you. On fibre to the premises, the biggest group here, that boundary is the NBN box on the wall.

1. 1
   

   Prove what reaches the box.

   A laptop cabled directly to the NBN box on fibre or HFC, or at the first socket on copper. If the speed is there, the network has delivered.

2. 2
   

   Test what the house adds.

   The cable from the box to the modem, the patch leads, any run to a study or the flat, each tested on its own. On copper, the extensions come off first.

3. 3
   

   Check the run to the flat.

   Where there's a granny flat, the link to it is tested end to end, and whatever is in the ground between the buildings is noted for the quote.

4. 4
   

   Fix it today, or write it up.

   Sorted on the day if the first hour allows, on your side. Written up for your provider, on NBN's.

   Read moreShow less

   A lead replaced, a socket taken off the line, or the modem set up and placed properly, on the visit, first hour permitting; a new run or conduit work is quoted. The network's faults go to your provider in writing. We can't make anyone fix their side, but if you want us with you all the way, we do everything in our power to get you a result. If you want photos and video too, that's the full escalation report.

A real job from the field

Seven Hills, NSW · FTTN · Filmed on site, 6 min

Five drop-outs a day in a factory complex. One patch lead was the worst of it.

On fibre to the node, a business in a Seven Hills factory complex had dropped out about five times a day for months. Indoor cable ran underground to the units. Swapping pairs changed nothing; replacing one patch lead in the office lifted the speed by about 20, and the drop-outs stopped.

Seven Hills, fibre to the node, a business in a factory complex. They were paying for 100 megabits and had been dropping out for months, about five times a day.

At the main frame the black cable from the street lands, and from it yellow indoor-grade cables run underground through conduits in the slab out to the factories. Indoor cable has no gel to keep moisture out, and the conduit area showed signs of water.

In the office the line gave about 53 at the modem’s port, and the same through the switch and router. A ping log through the switch showed latency and packet loss, so the networking was bypassed. Straight on the incoming pair at the main frame the speed was about 20 higher, but still short of what they pay for. Moving the office from pair one to pair two, then pair four of the cable to the units, left it at about 50.

Then a patch lead in the office was replaced with a new one, and the speed jumped by about 20. The next day there were no drop-outs, where there had been five, and a week later there were still none. The shortfall between the frame and the network remained, and the customer chose not to chase the extra speed.
