Internet Installation | NBN, Modem & New Connection Setup

Moving in, switching providers or connecting for the first time? NexusByte takes the pain out of internet installation across Sydney, handling everything between the box on the wall and every device in the building — for homes and businesses that just want to be online without the usual runaround.

Our technicians manage complete NBN setup and modem installation, plus 4G, 5G and Starlink connections where fixed-line isn't the answer. If your provider is dragging their feet, we'll liaise with them directly on your behalf, then connect your computers, phones, TVs and smart devices to a properly configured WiFi network.

Same-day service is available, so a missed connection date or dead modem doesn't leave you offline for a week. Whether it's a brand-new connection, an NBN fibre upgrade or an old setup that's never quite worked, we get you connected quickly, test everything before we leave, and explain it in plain terms.

What Is Internet Installation and Who Is It For?

Internet installation is the end-to-end job of getting a home or business online: installing and configuring the modem, activating the NBN or mobile broadband service, setting up WiFi and connecting every device that needs it. It is for anyone in Sydney moving house, switching providers, upgrading to fibre or connecting a place for the first time.

The gap this service fills is the one your provider leaves behind. The provider posts you a modem and considers the job done; everything after the box arrives, from working out which socket it plugs into, to activation, WiFi coverage and getting fifteen household devices reconnected, is on you. We take that whole stretch off your hands, and we liaise with the provider directly when activation stalls.

A live connection is only the starting point. Getting a strong signal into every room is a separate piece of work — see WiFi and home networking — and if the new connection is meant to carry lights, cameras and speakers as well, smart home installation covers getting those back online afterwards.

We handle NBN setup, standalone modem installation, fibre upgrades, provider switches, and 4G, 5G and Starlink connections, with same-day service available across Sydney.

How Should You Prepare for an NBN Setup?

A little preparation turns install day from a gamble into a formality. Before we arrive, it helps to know where your NBN connection box or wall socket is, have your provider account details on hand, and if you are moving house, order the service ahead of the move rather than after, since activations are rarely instant.

On the day, we check the NBN equipment, install and configure the modem, handle activation and then test the connection at the speed you are paying for. If your street is being upgraded to full fibre, our fibre upgrade support runs a pre-upgrade check, supports you through the installer's visit, upgrades the modem side if needed and verifies everything afterwards.

One tip from plenty of Sydney callouts: do not throw out the old modem until the new connection is proven. It is occasionally the fastest way to demonstrate to a provider that a fault is on their side of the line.

NBN, 4G/5G or Starlink: Which Connection Suits Your Home?

For most Sydney addresses, NBN is the default and the right answer, offering a stable fixed line with a wide choice of providers. The interesting decisions happen at the edges, and the right choice depends on your address rather than the marketing.

  • NBN: best all-rounder where the connection type at your address is solid; we can advise on what your street actually has
  • 4G/5G home broadband: strong where mobile coverage is good, and a genuinely useful stopgap while you wait for an NBN activation
  • Starlink: worth considering on acreage, in black spots or anywhere fixed-line options have consistently disappointed
  • Provider switch: sometimes the connection is fine and only the plan or provider is the problem; we reconfigure modems for a switch too

We install and configure all of them, including the hardware mounting and setup that 4G/5G and Starlink kits involve, and we test real-world speeds before we sign off rather than trusting the box's blinking lights.

Why Is the Internet Slow or Dropping Out After Installation?

A new connection that underperforms usually has an explainable cause. The modem may be tucked in a cupboard or a far corner where WiFi cannot reach the living areas, an old modem carried over from a previous provider may be half-compatible with the new service, or interference from neighbouring networks may be crowding the channel. Genuine line faults happen too, and they need to be demonstrated to the provider with evidence.

Our troubleshooting service works through that list methodically: line test, modem check, WiFi check, then the fix, so you end up with the speeds you are actually paying for. A stable connection matters double if you work from home, which is why many customers pair this with our home office setup service for a desk-to-internet chain that behaves during video calls.

New modem day has one more common casualty: the household printer, which stubbornly remembers the old network. Our printer reconnection service sorts that in the same visit. And once the network is solid, it is the ideal moment to add family-wide internet filtering at the router, covering every device in the house at once.

What Does Internet Installation Cost in Sydney?

Cost comes down to scope. A straightforward modem installation with WiFi setup sits at one end; a job involving new hardware, tricky modem positioning, a fibre upgrade or a long list of devices to reconnect sits at the other. Connection type matters as well, since a Starlink or 4G/5G setup involves physical hardware installation that a standard NBN swap does not.

What stays constant is how we price it: an assessment first, then a fixed quote before any work begins, with no hidden fees, and the no fix, no fee guarantee behind it. If we cannot get you online, you keep your money.

Laith went out of his way to fix my dad's computer when everything was closed. He came home and spared my dad the trouble of travel

Laith was reliable, helpful and professional - will be recommending.

Absolutely recommend NexusByte and will be first point of contact for any future hardware support and fix services, and hopefully dealing once again with Laith. The entire process was an A+ experience from the moment the call was answered, through to the diagnostic, repair and return of the damaged laptop. Laith is fantastic. In every element of his service and support. Very personable, engaging, knowledgeable and understands the critical importance of service to customers. He provided clear information for every step from booking the appointment, was on time for visiting my home for diagnosis + collection and for return of the item (on a weekend!), for what to expect through the diagnostic works, and for the quoting and payment process. The price for the services provided was very reasonable and affordable. One of the best service experiences I have had and right from 'go'.

I am so grateful of Laith's assistance today during a difficult and stressful time. Laith from NexusBytes is so knowledgeable, patient and compassionate. He was so calm which reassured me that I had found the right person. It took Laith only minutes to find the problem with my laptop and address it so that I could go safely back to work. I cannot recommend Laith and NexusBytes enough. I have already put his contact details in my phone for the next time I need tech help! Thank you Laith. Tracey

Amazing service. Job done, Lovely staff - highly recommend

Laith from Nexus Byte was fantastic from start to finish. He fixed my Sonos internet connectivity problem where others had tried and failed. I particularly liked that he contacted me the day after his service call to check that everything was still OK with my system. I would not hesitate to recommend Laith's services. Thanks again. Paul

The team at NexusByte are absolutely unreal! Laith and Natalie went above and beyond to help me with my repair/upgrade, and looked for the most cost effective options to suit my needs. They were both very communicative, knowledgeable and super flexible with pick-ups times. Just outstanding customer service all round. Thanks guys!
