For most homes, the best answer to the wired vs Wi-Fi question is both: cabled data points for the devices that stay put, and Wi-Fi for everything that moves. At Murphy's Electrical & Data, we often find that buffering movies, dropouts on video calls and laggy gaming have nothing to do with the NBN plan. The problem is what happens to the internet once it's inside the house. This guide explains where each option works best for homes in Nowra and the Shoalhaven.
Key Takeaways
- Wired data points give the most stable, secure connection for devices that stay in one place, such as smart TVs, gaming consoles and home office computers.
- Wi-Fi remains the practical choice for phones, tablets and laptops that move around the house.
- A combination of wired and Wi-Fi suits most homes, with reliability where it counts and flexibility everywhere else.
- Brick walls, distance from the router and neighbouring networks all weaken Wi-Fi. Good quality cabling such as Cat6 isn't affected by any of them.
- Murphy's Electrical & Data has over 25 years of experience in the Shoalhaven and NSW Electrical Contractor's Licence 275815C, and we install data cabling and NBN-ready cabling to suit your home.
Wired vs Wi-Fi: A Quick Comparison For Homeowners
A wired connection is faster, steadier and more secure, while Wi-Fi wins on convenience. Here's how the two compare on the things that matter in a typical Shoalhaven home.
- Speed: A wired connection delivers close to the full speed of your connection to the device. Wi-Fi speeds drop with distance from the router and with every wall in the way.
- Reliability: Once a cable is installed properly, dropouts are rare. Wi-Fi is affected by brick walls, metal roofs, microwaves and neighbouring routers, so performance moves up and down through the day.
- Security: Someone needs physical access to your home to tap into a cable. Wi-Fi relies on a strong password, encryption and up-to-date router firmware.
- Convenience: A cable ties a device to one spot. Wi-Fi lets you move around freely, which is why it suits phones and tablets.
Most Nowra homes do best with a mix of the two rather than choosing one.
How Home Internet Actually Reaches Your Devices
Your internet travels through three stages before it reaches your devices, and the last stage inside your home matters as much as the NBN connection itself.
- The NBN connection arrives at your property using the technology for your address, such as fibre to the premises, fibre to the node, fibre to the curb or HFC.
- An NBN connection box inside your home marks the point where the external network ends and your equipment begins.
- Your modem or router passes the connection to your devices, either through Ethernet cables or over Wi-Fi.
A lot of "slow internet" complaints come down to the third stage: a router stuck in a far corner, or no cabling to the rooms that need it. Moving or adding data points so the router sits centrally can improve both your wired and wireless coverage. Good internal cabling also gives you a solid backbone for Wi-Fi access points in other parts of the house.
When a Wired Home Network Is the Better Choice
A wired connection is the better choice for any device that stays in one place and needs a steady connection. That covers:
- Home offices. Video calls, cloud backups and large uploads all need a consistent connection. A cable avoids the lag spikes that freeze calls and stall uploads.
- Home entertainment. Smart TVs, streaming boxes and media servers stream more smoothly over a cable. For 4K streaming, a stable connection matters more than raw speed.
- Gaming. A wired connection gives lower, steadier latency than Wi-Fi, which is the difference between a smooth online match and constant lag.
- Security systems. CCTV recorders, wired cameras and smart home hubs are more reliable on a cable and won't drop out when the Wi-Fi is busy.
- Larger or double-storey homes. Brick veneer and older fibro homes around Nowra, Bomaderry and Worrigee can be hard on Wi-Fi. Cabling with access points in key rooms often fixes dead spots that no new router can.
Moving your heaviest users onto cable also frees up Wi-Fi capacity for everyone else in the house.
Where Wi-Fi Still Shines
Wi-Fi is the right choice for anything you carry around the house. Nobody needs a cable running to their phone.
- Phones, tablets and laptops that move between rooms are best served by strong Wi-Fi, ideally fed from a wired backbone.
- Browsing, social media and everyday streaming generally work well over Wi-Fi when the router is in a good spot.
- Many thin laptops, tablets and smart home gadgets don't have an Ethernet port, so Wi-Fi is their only option.
- Mesh Wi-Fi systems extend coverage, and they work best when each unit connects back to the router by cable.
- Some smart plugs and light switches only work over Wi-Fi, so good coverage across the whole house still matters.
Murphy's Electrical & Data can place data points so Wi-Fi access points sit where they'll cover the most of your home, which cuts down on dead zones.
Speed, Stability and Security: How Wired and Wi-Fi Really Compare
Speed gets most of the attention, but stability and security matter just as much when you're planning a home network.
Speed. A wired connection consistently delivers close to its full rated speed. Cat6 cabling handles gigabit speeds comfortably and leaves headroom for faster connections in future. Wi-Fi throughput drops the further a device is from the access point, and it shares crowded radio channels with every other device and neighbouring network.
Stability. A properly installed cable gives the same performance all day. Wi-Fi can rise and fall depending on household use, interference and how many devices are sharing it.
Security. A cable can only be tapped by someone inside your home. A Wi-Fi network needs a strong password, WPA3 encryption where your router supports it, and up-to-date firmware.
A mixed network lets you keep work computers and network storage on cable and leave everyday devices on Wi-Fi.
Planning a Mixed Wired and Wi-Fi Network in a Shoalhaven Home
The best time to plan your home network is during a renovation, extension or new build, while walls and ceilings are open. Here's a simple checklist:
- List the devices that stay in one place, such as TVs, desks and security systems, and mark where data points would go in living areas, the home office and the media room.
- Put the main router somewhere central. If the NBN connection box is in the garage or a far corner, run cable back to a better spot.
- Run extra cables while the walls and ceilings are open, because retrofitting later is more disruptive.
- Allow at least two data points at key spots, such as behind the main TV or in the home office, to leave room for future equipment.
- Choose Cat6 over Cat5e. It's the better long-term choice as internet speeds keep climbing.
Murphy's Electrical & Data can advise on cable routes, NBN-ready cabling and data point placement to balance wired performance with strong Wi-Fi coverage.

FAQs: Wired vs Wi-Fi in Your Home
Do I need data cabling if my Wi-Fi already works okay?
Not everywhere, but a few cabled data points in the right places can noticeably improve streaming, gaming and work-from-home calls. If you watch a lot of 4K content or rely on video calls for work, a single data point behind the TV or at your desk is often worth it.
Can I mix wired and Wi-Fi on the same home network?
Yes. Almost every modern router supports both at the same time. You can plug some devices in by cable and leave the rest on Wi-Fi without any conflict, and for most households that's the best balance of speed and flexibility.
Is it worth adding network cabling to an existing home, or only new builds?
It's worth it in existing homes too. Retrofitting is common around Nowra, especially during renovations or other work in the roof space. An experienced electrician can plan cable runs to keep cutting and patching to a minimum, and the earlier you raise it in a renovation, the easier it is.
Will wired data cabling improve my NBN speed?
Cabling won't raise the maximum speed of your NBN plan, but it lets your devices actually get close to that speed by removing the bottlenecks inside your home. Wi-Fi drop-off and congestion are often why devices see much less than the speed you're paying for.
How do I get started with upgrading my home network?
Start by listing the problem spots: the TV that keeps buffering, the home office with slow uploads, the bedroom where Wi-Fi drops out. Then call Murphy's Electrical & Data on 0423 529 267, and we'll talk through your options and arrange an on-site assessment.
