It seems the M5 uses a wide 40MHz channel in 2.4Ghz mode instead of the recommended 20MHz. How can we change that?
Also would be nice if we could to change the wifi channels in advanced settings. Will this be added to a new FW soon?
2.4GHz channel width
Channel width controls how large of a "pipe" 'is available to transfer data. However, larger channels are more subject to interference and more likely to interfere with other devices. A 40MHz channel is sometimes called a wide channel, and a 20MHz channel is a narrow channel.
Set to: 20MHz
Use 20MHz channels in the 2.4GHz band. Using 40MHz channels in the 2.4GHz band can cause performance and reliability issues with your network, especially in the presence of other Wi-Fi networks and other 2.4GHz devices. A 40MHz channel might also cause interference and issues with other devices that use this band, such as Bluetooth devices, cordless phones, and neighboring Wi-Fi networks. Routers that don't support 40MHz channels in the 2.4GHz band do support 20MHz channels.
