- However, if older or IoT devices dominate your setup, keeping the 2.4 GHz band active is advisable.
2. Size and Layout of Your Space
Evaluate the geographical layout of your living space:
• In larger homes, consider maintaining both bands to ensure comprehensive coverage.
• If your home is smaller or the layout allows for solid 5 GHz coverage, disabling 2.4 GHz could work strategically.
Creating an Optimal Setup
To achieve the best performance in your home network, consider these strategies:
• Position your router centrally to maximize the reach of both frequency bands.
• Use a dual-band router that supports both 2.4 GHz and 5 GHz networks simultaneously, allowing you to selectively connect devices to the most suitable band.
Conclusion
Deciding to disable the 2.4 GHz band on your router is not a one-size-fits-all solution. While it may enhance security and reduce interference in some cases, it can also lead to connectivity issues for various devices.
Understanding your network needs, the devices you own, and your living space’s characteristics will guide you to the right decision. Embrace both frequency bands for optimal performance, as a well-rounded approach often yields the best outcomes for most home networks in today’s digital world.

What are the main differences between 2.4 GHz and 5 GHz Wi-Fi?
The 2.4 GHz frequency offers a longer range and better penetration through walls and obstacles, making it suitable for larger spaces or environments where coverage is needed throughout multiple rooms. However, it tends to be more congested since many devices, including older ones, primarily operate on this frequency, potentially leading to interference and slower speeds.
On the other hand, the 5 GHz frequency provides faster speeds and less interference, which can significantly enhance performance for streaming and gaming. However, its shorter range can be limiting, especially in larger homes or buildings. Disabling the 2.4 GHz network may push all devices to connect to the 5 GHz network, which could improve performance but may also lead to issues if some devices can’t connect due to range limitations.
What devices will be affected if I disable 2.4 GHz?
If you disable the 2.4 GHz band on your router, any device that only supports this frequency will be unable to connect to your Wi-Fi network. This includes a variety of older devices, such as smartphones, tablets, smart home devices, or IoT gadgets that do not have compatibility with 5 GHz.
Additionally, some non-legacy devices might have stronger connections on 2.4 GHz due to their higher placement or distance from the router. Therefore, while modern devices typically support both bands, some older or less advanced devices may become inoperable upon disabling the 2.4 GHz option, potentially leading to connectivity issues in your home.
Will disabling 2.4 GHz improve Wi-Fi speed?
Disabling the 2.4 GHz band can improve the overall Wi-Fi speed for devices that connect exclusively to the 5 GHz band, as it reduces network congestion and potential interference from the crowded 2.4 GHz spectrum. This is especially advantageous in densely populated areas where many networks are competing for the same frequency, thereby enhancing the performance of devices capable of using 5 GHz.
However, this improvement will only benefit those devices that are 5 GHz compatible. If many of your devices rely on the 2.4 GHz band, the overall speed and performance of your network may decline as these devices can no longer connect, leading to a less satisfactory experience for users relying on those connections.
