"Try restarting the router" is the most overused piece of tech advice on the internet. Restarting the router doesn't fix bad channel configuration, it doesn't fix band steering, and it definitely doesn't fix the fact that your Zigbee smart home hub is fighting your Wi-Fi for the same radio spectrum.
We've set up home networks across the Gold Coast for years. Here's what we actually see causing Wi-Fi problems in modern homes - and it's almost never what people think.
The Hidden Culprit: Band Steering
Modern routers - and virtually every consumer mesh system - broadcast a single Wi-Fi network name (SSID) covering both 2.4 GHz and 5 GHz. The router's "band steering" algorithm is supposed to intelligently move devices to whichever band is better at any given moment.
In theory: great idea. In practice: a constant source of problems.
Band steering forces devices to constantly re-evaluate which band they should be on. This negotiation process causes brief but regular dropouts - you'll notice it as video calls stuttering, gaming lag spikes, or smart home devices being unresponsive for a few seconds at a time. Your phone sitting 2 metres from the router gets pushed onto 2.4 GHz because the algorithm made the wrong call. Your laptop at the other end of the house gets forced onto 5 GHz, which barely reaches that far. Band steering doesn't always get it right.
IoT devices are particularly affected. Smart bulbs, plugs, cameras, and sensors are typically 2.4 GHz-only. Band steering on a combined network can cause these to disconnect and reconnect repeatedly, especially if the router is trying to push them to 5 GHz.
The fix: Disable band steering and broadcast separate SSIDs for 2.4 GHz and 5 GHz - for example HomeWifi_2G and HomeWifi_5G. Connect devices manually to the appropriate band. IoT devices go on 2.4 GHz. Phones, laptops, and streaming devices go on 5 GHz.
Channel Congestion in the 2.4 GHz Band
The 2.4 GHz band has 13 channels in Australia, but only three are non-overlapping: channels 1, 6, and 11. Every other channel bleeds into its neighbours. Most routers default to "Auto" channel selection, which often means every router in your street picks channel 6 - and they all interfere with each other.
In a house, this is annoying. In an apartment building in Surfers Paradise or Broadbeach with 50 nearby Wi-Fi networks, "Auto" channel selection is a performance disaster.
The fix: Manually set your 2.4 GHz Wi-Fi to channel 6 in your router settings. Use a Wi-Fi analyser app (WiFi Analyzer on Android, or Wi-Fi Explorer on Mac) to see what your neighbours are using, and pick the least congested non-overlapping channel.
Zigbee and IoT Interference
Zigbee is the wireless protocol used by most smart home devices - Philips Hue, IKEA TRÅDFRI, Samsung SmartThings, SONOFF Zigbee devices, and anything running Zigbee2MQTT. It operates on the 2.4 GHz band, and its channels overlap directly with Wi-Fi channels.
Zigbee channel 11 sits at 2.405 GHz - almost directly on top of Wi-Fi channel 1. Zigbee channels 15-20 overlap with Wi-Fi channels 1-6. If your Zigbee coordinator is set to a channel that overlaps with your Wi-Fi, your smart home devices and your Wi-Fi network are essentially fighting each other for airtime. The result: slow or unresponsive smart home devices, and degraded Wi-Fi performance for nearby clients.
The fix: Set your Zigbee coordinator (Philips Hue bridge, IKEA hub, Home Assistant with a Zigbee dongle, etc.) to Zigbee channel 25, which sits at approximately 2.475 GHz. This is above the standard Wi-Fi channel range and has minimal overlap with Wi-Fi channel 6 (2.437 GHz). The two systems are now as far apart as the spectrum allows.
While you're at it, put all your IoT devices on a separate SSID from your main Wi-Fi. Even with channel optimisation, 25 IoT devices competing with your laptop for airtime on the same 2.4 GHz network slows everything down. A dedicated IoT SSID also improves security - a compromised smart plug can't reach your main devices.
Your Mesh System Can't Fix Any of This
Consumer mesh Wi-Fi systems - Google Nest WiFi, Amazon Eero, TP-Link Deco - are designed to be plug-and-play. That simplicity is their greatest strength and their biggest limitation.
What they do well: simple app-based setup, good whole-home coverage, and seamless roaming between nodes. What they can't do: disable band steering, manually set Wi-Fi channels, create VLANs to isolate IoT devices, or broadcast separate 2.4 GHz and 5 GHz SSIDs.
Some mesh systems have an "AP mode" or "bridge mode" that, when enabled, can expose additional advanced settings. It's worth trying - switch your mesh system to AP mode in the app settings and check if manual channel selection or band steering controls appear. But in our experience, most consumer mesh systems - even in AP mode - simply don't provide the settings needed to properly configure a network with smart home devices. The hardware and firmware just weren't built for it. Sometimes mesh systems simply don't cut the mustard.
Better Options for Australian Homes
If your home needs proper network control, here are the options we recommend:
Ubiquiti UniFi - hugmypc's Recommendation
For most homes that need advanced networking capability, we recommend Ubiquiti UniFi. The UniFi Dream Router or UniFi Dream Machine as your gateway, combined with one or more UniFi U6 Lite or U6 Pro access points, gives you complete control: manual channel selection on all bands, granular band steering control, full VLAN support for IoT isolation, multiple SSIDs with independent settings, and client device visibility and bandwidth monitoring.
Available in Australia from Scorptec, Mwave, and PLE Computers. A complete setup - Dream Router plus one U6 Lite access point - runs approximately $500-$700. More than a $200 mesh system, but it actually solves the problem.
ASUS with AiMesh
ASUS routers running AiMesh (models like the RT-AX86U or RT-AX88U) offer significantly more advanced settings than Google, Eero, or Deco - including manual channel selection, separate SSID control per band, and basic band steering management. Available at JB Hi-Fi and Mwave for $350-$600. A good choice if you want more control than consumer mesh but aren't ready to step up to Ubiquiti.
TP-Link Omada
TP-Link's Omada range (separate from their consumer Deco mesh) is a business-grade Wi-Fi system with a centralised controller - the OC200 hardware controller or a software controller running on a Raspberry Pi or NAS. Full channel control, VLAN support, multiple SSIDs, and band steering settings. An EAP670 access point plus OC200 controller runs around $300-$400.
Synology Router
Synology's RT6600ax and MR2200ac routers run SRM (Synology Router Manager), a mature OS with proper network segmentation, VLAN support, manual channel selection, and a well-designed interface. If you're already using a Synology NAS, this integrates cleanly. Available from Scorptec and Mwave; the RT6600ax runs approximately $450.
When Consumer Mesh Is Fine
Consumer mesh systems are not bad products. They're the right tool for the right situation. If you have a small apartment, fewer than 15 devices, no Zigbee or Z-Wave smart home setup, and Wi-Fi that's generally working fine - a Google Nest WiFi or TP-Link Deco is a perfectly good choice.
The problem arises when you have 30+ devices, a smart home system using Zigbee, and performance issues you can't resolve. That's the situation where consumer mesh reaches its limits, and where a router with proper advanced settings becomes the right answer.
Quick Checklist: What to Do First
- Check your Zigbee coordinator channel - set it to channel 25 if possible
- Set your 2.4 GHz Wi-Fi to channel 6 manually - disable "Auto" channel selection
- Try disabling band steering in your router's advanced wireless settings
- Separate your IoT devices - create a second SSID just for smart home devices
- Switch your mesh to AP mode and see if extra settings appear
- If none of the above is possible in your router's settings - it's time for hardware that actually supports it
We Fix Home Networks the Right Way
hugmypc sets up home networks across the Gold Coast - properly. That means channel configuration, band steering, IoT isolation, Zigbee optimisation, and recommending the right hardware for your specific situation. We won't oversell you a system you don't need, but we won't leave you with a mesh router that can't solve your actual problem either.
