Setting a fixed 2.4 GHz Wi-Fi channel on your Smart Hub can improve performance if your Wi-Fi connection is slow or unstable. Follow the steps in this article to change your channel.
Your Smart Hub acts like a Wi-Fi traffic controller, constantly steering your phone, laptop, and smart TV into different 'lanes' (channels) to avoid traffic jams.
It does this automatically behind the scenes to ensure that you always have the fastest, cleanest connection possible with minimal interference. While we recommend you leave your hub to do this, there are some rare situations where you may want to use a fixed wireless channel instead:
Stubborn Smart Devices
Some older 2.4GHz devices like smart plugs, security cameras and lightbulbs can struggle to stay connected when your hub is switching channels in the background. Some device manufacturers may also recommend that you avoid the use of certain channels.
Wi-Fi interference
If you live next to a source of Wi-Fi interference, or have radio or electrical equipment in your home that is known to disrupt Wi-Fi signals, then forcing your hub to stay on a completely different channel can help bypass the problem.
Choosing the right Wi-Fi channel on your hub can make a big difference to performance, especially on the 2.4 GHz band. In a busy area, where many networks overlap.
Setting a fixed channel (usually 1, 6, or 11) can reduce interference, improve stability, and give more consistent speeds. It is worth making the occasional check, as the best channel for your home can change over time.
Fixing your Wi-Fi channel may seem like a 'quick fix' for some things, but it can do more harm than good. Wireless traffic changes by the second, and a channel that is 'good' one minute may be 'bad' the next.
Fixing the Wi-Fi channel is like turning off 'auto-pilot' and could result in your router sitting in traffic, rather than taking a faster detour.
