NORTHERN SYDNEY
FTTB, FTTN, HFC.
WE DIAGNOSE THEM ALL.
An internet technician from SECURE A COM diagnoses and repairs NBN faults across Northern Sydney — from apartment buildings in Chatswood and St Leonards to heritage homes in Mosman, Neutral Bay, and Ku-ring-gai. We specialise in FTTB MDF pair fault diagnosis, bridge tap removal in period properties, and FTTN line attenuation testing using professional test equipment ISPs won't deploy. An Open Registered Cabler (A10089) attends on-site, with 90% of faults resolved in a single visit.
WHY NORTHERN SYDNEY INTERNET FAULTS GO UNFIXED
Northern Sydney has one of the most complex NBN mixes in greater Sydney — FTTB in high-rise apartments, FTTN across Ku-ring-gai, and ageing internal wiring in heritage properties. Here's why ISPs consistently fail to fix these faults.
ISPs Test Remotely — Apartment Fibre Shows Active, Copper Pair Ignored
For FTTB buildings, ISPs check that the fibre feed to your building's equipment room is active — and it almost always is. They cannot see the copper pair between the building's patch panel and your apartment, nor the MDF pair assignment in the comms room. If the fibre hand-off records active, the ticket is closed. Every apartment resident in Chatswood, St Leonards, and Artarmon who has been told "the line is fine" knows exactly what this looks like.
FTTB MDF Pair Faults — Chatswood, St Leonards, North Sydney High-Rises
FTTB (Fibre to the Building) delivers fibre to your building's comms room, then copper pairs run to each apartment. The Main Distribution Frame in the comms room is where those pairs are assigned — and incorrect Krone IDC pair assignments, cross-connections, and corroded punch-down blocks are common causes of poor FTTB performance. ISP contractors will not access or repair MDF wiring. We carry Krone IDC tools and the expertise to diagnose and correct these faults on the same visit.
Heritage Wiring in Period Homes — Mosman, Cremorne, Neutral Bay, Kirribilli
The inner northern suburbs of Sydney have some of the oldest residential housing stock in the country. Mosman, Cremorne, Kirribilli, and Neutral Bay properties from the 1920s through 1960s were wired for telephone service during original construction — and that wiring has never been removed. Multiple extension sockets wired in parallel create bridge taps that devastate FTTC and FTTN performance. We identify and isolate every active extension, typically restoring near-plan-rate speeds within the same visit.
FTTN Long Copper Runs — Gordon, Killara, Lindfield, Ku-ring-gai
The upper North Shore suburbs served by FTTN — Gordon, Killara, Lindfield, Roseville, Pymble, Turramurra, and Wahroonga — can have significant copper distances from the node to the premises. The longer the copper run, the higher the line attenuation and the lower the maximum achievable sync speed. ISPs classify these speeds as "within tolerance" even when they represent a fraction of your plan rate. We measure actual line attenuation on-site and identify any internal wiring faults that compound the distance problem.
HFC Coax Degradation — Intermittent Dropouts on Cable NBN Connections
Several North Sydney and Willoughby suburbs are served by HFC (Hybrid Fibre-Coaxial) where the NBN connection uses a coaxial cable to your premises. Corroded or damaged coax splitters, poorly terminated F-connectors, degraded RG-6 cable from the pit, and signal splitting across multiple TV points can all cause intermittent dropouts that clear up between incidents — making them hard for ISPs to capture remotely. We test the coax path from the street to the connection box and identify the degradation point on-site.
Strata Building Comms Rooms — ISP Won't Do MDF Work in Apartment Blocks
Strata-managed apartment buildings across Northern Sydney — particularly in Chatswood, North Sydney CBD, Artarmon, St Leonards, and Crows Nest — have building comms rooms that ISP contractors will not enter to perform MDF work. The official position is that the fault is "inside the building" and therefore the responsibility of the building owner or strata. In practice, this means faults in the building's MDF never get fixed — until a private Open Registered Cabler attends, accesses the comms room, and repairs the wiring directly.

Lead-in cable installationFROM YOUR FIRST CALL TO FIXED — ACROSS NORTHERN SYDNEY
Here's exactly what happens when you book an internet technician with SECURE A COM in Northern Sydney. We travel from our Miranda base, arrive on-site with professional test equipment, and diagnose FTTB, FTTN, FTTC, or HFC faults — most resolved within the first visit.
Book Online — Tell Us Your Connection Type and Fault Symptoms
Call us on 02 9188 1577 or use the online booking form. Tell us your NBN type if you know it (FTTB, FTTC, FTTN, or HFC), your address, and what's happening — slow speeds, dropouts, apartment speeds way below plan, or intermittent connection. You don't need technical knowledge. We'll ask the right questions and advise on the most likely cause based on your address and connection type before we arrive. We've diagnosed NBN faults across Northern Sydney since 2008.
We Confirm Your Appointment — Specific Arrival Window
We confirm an exact arrival window — not a vague half-day block. Northern Sydney is approximately 30–45 minutes from our Miranda base depending on location and traffic. We confirm the visit date, arrival window, and any access requirements — building entry, comms room access arrangements with your building manager, parking, and any strata-specific requirements. We handle the comms room coordination ourselves where possible.
On-Site Fault Diagnosis — MDF Access, Copper Pair Testing, Comms Room
We arrive with professional telecommunications test equipment — VDSL2 analysers, Krone IDC tools, copper pair testers, TDR, and HFC signal level meters — and begin a systematic diagnosis. For FTTB apartments, we access the building comms room and inspect the MDF directly. For heritage homes in Mosman or Cremorne, we trace the internal wiring for bridge taps. For FTTN in Ku-ring-gai, we measure actual line attenuation from the socket. This is the step your ISP has never taken.
Repair Carried Out On-Site — Same Visit
In 90% of cases, we carry out the repair on the same visit. Krone IDC re-termination in the comms room, MDF pair jumpering, bridge tap isolation in heritage wiring, HFC F-connector replacement, or lead-in cable repair — we carry the tools and materials to complete these repairs immediately. Where the fault is an ISP or NBN Co infrastructure issue, we provide written documentation for escalation — evidence ISPs cannot ignore.
Speed Verified, Results Explained, Guarantee Issued
Before we leave, we re-test your connection speed and confirm the fault is resolved. We walk you through what we found and what was done — in plain language. You receive a 12-month workmanship guarantee on all repairs carried out. If the same fault recurs within 12 months due to our workmanship, we return at no additional charge.

We created this page because we genuinely service Northern Sydney — regularly attending apartment buildings in Chatswood, St Leonards, and North Sydney, and heritage homes across Mosman, Neutral Bay, and Ku-ring-gai. We travel to Northern Sydney because very few private Open Registered Cablers will access building comms rooms, diagnose FTTB MDF pair faults, or carry the specialist equipment to test all NBN connection types on-site. Northern Sydney is within our Greater Sydney service area — no additional travel surcharge applies for standard Greater Sydney addresses. For locations outside Greater Sydney, travel charges apply per our Terms & Conditions.
