There is nothing more frustrating than settling in for a movie night or an intense gaming session, only to be met with buffering, lag, or a dropped connection. If your smart TV experience isn’t as smooth as it should be, the problem almost certainly comes down to your network setup. The good news is that with a few straightforward changes, you can dramatically improve the performance of your smart TV for both streaming and gaming.
Here’s everything you need to know about setting up your smart TV network the right way.
Why Your Network Setup Matters for Smart TVs?
A smart TV is only as good as the internet connection feeding it. Unlike browsing the web on a laptop or checking emails on your phone, streaming high-definition video and online gaming are incredibly demanding on your network. A 4K HDR stream can require anywhere from 15 to 25 Mbps of consistent bandwidth, and online gaming adds the extra challenge of requiring low latency — not just speed.
If your network isn’t set up properly, you’ll experience buffering during streams, pixelated picture quality, game lag, and dropped connections. Getting your setup right from the beginning saves you a lot of frustration down the track. If you’re also setting up a new TV, our TVs and home theatre service can help you get everything configured correctly from day one.
Step 1: Wired vs Wireless — Know the Difference
The very first decision you need to make is whether to connect your smart TV via an Ethernet cable or rely on Wi-Fi. This single choice has the biggest impact on your overall experience.
Wired Ethernet Connection
A wired connection is almost always the better option for a smart TV. Because the signal travels directly through a physical cable rather than through the air, you get faster speeds, lower latency, and a far more stable connection. There are no wireless interference issues, no signal dropoffs, and no competition with other devices for bandwidth.
If your router is reasonably close to your TV, running an Ethernet cable is a simple and highly effective solution. Most smart TVs have a built-in Ethernet port, and a good quality Cat6 cable is all you need to get started. For longer runs or a more permanent solution, our network cabling service can handle the installation cleanly and professionally throughout your home.
Wireless Wi-Fi Connection
If running a cable isn’t practical — for example, if your TV is in a room far from your router — Wi-Fi is the next best option. The key is making sure your WiFi setup is optimised for the demands of streaming and gaming, which we’ll cover in detail below.
Step 2: Choose the Right Router
Your router is the heart of your home network, and an outdated or underpowered router can be the single biggest bottleneck in your setup. If your router is more than four or five years old, upgrading it could make an immediate and noticeable difference to your smart TV experience.
When choosing a router for streaming and gaming, look for the following:
Wi-Fi 6 or Wi-Fi 6E Support
Wi-Fi 6 is the current standard for home networking and offers significantly faster speeds, better performance in busy households with many connected devices, and improved efficiency overall. Wi-Fi 6E takes things further by adding the 6 GHz band, which is less congested and delivers even faster, more reliable connections.
Dual or Tri-Band Capability
A dual-band router broadcasts on both the 2.4 GHz and 5 GHz frequencies. The 5 GHz band is faster and less congested, making it ideal for streaming and gaming. A tri-band router adds an additional 5 GHz band, which is particularly useful in busy households where multiple people are streaming or gaming at the same time.
Quality of Service (QoS) Settings
QoS is a feature that allows your router to prioritise certain types of traffic — for example, giving your smart TV’s streaming traffic priority over someone else downloading files in another room. This can make a significant difference during peak usage periods. If you’re unsure which router is best suited to your home, our equipment consultation service can help you make the right choice.
Step 3: Position Your Router Strategically
Even the best router in the world won’t perform well if it’s tucked away in a cupboard, hidden behind a stack of books, or positioned at the far end of the house from your TV. Router placement has a huge impact on Wi-Fi signal strength and quality.
For the best results, place your router in a central, elevated location in your home — ideally in the same room as your TV or as close to it as possible. Keep it away from thick walls, large metal objects, microwaves, and other devices that can cause interference. Make sure it’s out in the open rather than enclosed in a cabinet or cupboard.
If your router simply can’t be moved closer to your TV, consider using a powerline adapter, which sends your internet signal through your home’s existing electrical wiring, or look at a home networking solution to extend coverage properly across your entire property.
Step 4: Consider a Mesh Wi-Fi System
If your home is large, has multiple storeys, or has thick walls that block Wi-Fi signals, a mesh Wi-Fi system is one of the best investments you can make for your network. Unlike a traditional router and range extender setup — which can create inconsistent connections as your devices switch between the two — a mesh system creates a single, seamless network across your entire home.
Mesh systems use multiple nodes placed around your home to blanket every room with a strong, consistent signal. Your smart TV will always connect to the nearest and strongest node automatically, without any manual switching or signal dropoff. Our professional mesh WiFi setup Melbourne service takes care of everything — from choosing the right system for your home to optimising node placement for maximum coverage.
This is particularly valuable for gaming, where even a momentary loss of signal can mean the difference between winning and losing.
Step 5: Use the 5 GHz Band for Your Smart TV
If your smart TV is connecting to Wi-Fi, always make sure it’s connecting to the 5 GHz band rather than the 2.4 GHz band. The 2.4 GHz band has a longer range but is significantly more congested — it’s the same frequency used by many other household devices including microwaves, baby monitors, and neighbouring Wi-Fi networks.
The 5 GHz band is faster, less congested, and far better suited to the demands of 4K streaming and online gaming. Most modern smart TVs and routers support 5 GHz, so switching is usually just a matter of going into your TV’s Wi-Fi settings and selecting the correct network.
Step 6: Optimise Your Internet Plan
Your network setup can only perform as well as the internet connection coming into your home allows. If your NBN or broadband plan doesn’t provide enough speed or bandwidth, even the best router and network configuration won’t fully solve your problems. Our NBN installation Melbourne service can ensure your connection is set up correctly and performing at its full potential from the very start.
As a general guide, here’s the minimum internet speed you should aim for based on your usage:
- Standard HD Streaming (1080p) – At least 10 Mbps
- 4K Ultra HD Streaming – At least 25 Mbps
- Online Gaming – At least 25 Mbps with low latency (under 50ms ideally)
- Multiple Devices Streaming Simultaneously – 50 Mbps or more
If your current plan falls short of these figures, it may be time to upgrade. Our internet installation service can help you get the right connection in place and ensure everything is configured for the best possible performance.
Step 7: Reduce Network Congestion
Even with a fast internet plan and a good router, your smart TV’s performance can suffer if too many devices are competing for bandwidth at the same time. Every device connected to your network — smartphones, tablets, laptops, smart speakers, and security cameras — uses a share of your available bandwidth.
Here are a few ways to reduce network congestion and free up bandwidth for your smart TV:
- Disconnect devices that aren’t in use from your Wi-Fi network.
- Schedule large downloads and updates on other devices to run overnight rather than during peak streaming or gaming hours.
- Use your router’s QoS settings to prioritise traffic to your smart TV.
- Consider setting up a separate guest network for visitors so their devices don’t compete with your own.
For households with a large number of connected devices, our multi-device setup service can help organise and optimise your entire network so every device gets what it needs without slowing everything else down.
Step 8: Update Your Smart TV’s Software
It sounds simple, but keeping your smart TV’s software and firmware up to date can have a real impact on streaming and gaming performance. Manufacturers regularly release updates that improve app stability, fix bugs, and optimise network performance. Most smart TVs will check for updates automatically, but it’s worth going into your TV’s settings and checking manually if you’ve been experiencing issues.
While you’re in the settings, also check that your streaming apps — Netflix, Disney+, Stan, YouTube, and others — are updated to their latest versions, as outdated app versions can cause buffering and playback issues. If you need help getting your streaming device setup sorted, our team can handle the entire process for you.
Step 9: Check Your DNS Settings
This is a more advanced tip, but one that can make a meaningful difference to streaming speeds. Your DNS (Domain Name System) server translates website addresses into IP addresses and plays a role in how quickly your smart TV connects to streaming servers.
By default, your TV will use your internet provider’s DNS servers, which aren’t always the fastest. Switching to a faster public DNS service — such as Google’s DNS or Cloudflare’s DNS — can reduce connection times and improve the responsiveness of your streaming apps. This setting can usually be changed in your TV’s network or internet settings menu. If you’re also looking to protect your network while you’re at it, our VPN setup service adds an extra layer of security to your home connection.
Step 10: Think About Your Whole Home Entertainment Setup
Getting your smart TV network right is just one piece of the puzzle. For the best possible entertainment experience at home, it’s worth thinking about your entire setup — from your TV placement and sound system to your streaming devices and smart home integration.
Our home theatre installation service can bring everything together into a seamless, high-performance setup, and our smart home installation team can integrate your TV with the rest of your connected devices for a truly modern home entertainment experience. If you’re thinking about mounting your TV on the wall for a cleaner look, our TV wall mounting installation service handles that too — including cable management for a neat, professional finish.
Step 11: Get Professional Help When Needed
