Internet slow, dropping out every evening, or completely dead — and rebooting the router has stopped working as a strategy? We're the internet technicians Sydney calls when the problem needs to actually get fixed: on-site, same-day where possible, in English or Chinese.
Dead connections traced fast: NBN box lights, line sync, account status, hardware failure or an outage — we find which within the first half hour and act on it.
Connections that die at random or every night at the same time. We trace interference, overheating hardware, line faults and provisioning errors to the actual trigger.
Paying for 100Mbps and getting 15? We benchmark on cable at the source, then locate where the speed dies — plan, line, modem, router or WiFi.
Half of "broken internet" is actually WiFi. We test both sides separately so you never pay to fix the wrong thing.
Internet faults hide in a chain: ISP network → street infrastructure → your NBN box → in-home wiring → modem → router → WiFi → device. Guessing means replacing parts until something works. We measure instead — professional line and WiFi diagnostics at each link — so the fix targets the one link that's actually broken.
Since early 2025 we've completed 750+ jobs across Sydney, most of them exactly this: the fault nobody else would sit down and isolate. Apartment buildings around UNSW, FTTB towers in the CBD, double-brick houses in the east — each has its own failure patterns, and we've seen them all.
When the fault is on the ISP or NBN side, we don't just tell you — we document it and call the provider with you or for you, in English, with measurements attached. Tickets with independent evidence get escalated; "my internet is slow" gets a reboot script.
Describe the symptom and when it happens — constant, evenings only, rainy days, one room only. The pattern already narrows the cause.
Same-day visit where possible. We benchmark at the NBN box first, then test each link inward until the fault shows itself.
Your-side faults fixed on the spot where parts allow; cabling repairs handled with our partnered ACMA-registered cablers.
Network-side faults escalated to the ISP with evidence, and we verify the fix afterwards — the job isn't done until the internet is.
Repair visits start at $150 including full diagnosis, with the diagnosis fee credited toward the repair. You approve any parts or cabling quotes before work happens. If it turns out to be a network fault we can't legally or physically touch, you pay for the diagnosis and evidence report only — never for a repair that didn't happen.
Random collapses the ISP couldn't see — a failing in-wall cable run, found and fixed.

Read case →The most common causes: an overheating or ageing modem, interference on WiFi, a failing wall socket or in-wall cable, power issues, congested channels in apartments, or a genuine line fault. Each has a distinct signature — see our full 7-cause guide.
Full guide →Remote tests only see to your NBN box. Everything past it — wiring, socket, modem, router, WiFi — is invisible to them and is your responsibility. That inside half is exactly what we test, fix and document.
