What are channels and how do they affect my network?
Our routers use both the 2.4 GHz or 5 GHz frequency bands for wireless communication. Some routers are dual-band, so you can choose which frequency band to use. This could explain why you may see two networks, one which is Network and one which is Network_5G, for example.
Within these frequency bands, there are smaller bands called Wi-Fi channels. Some channels may not be the best choice due to interference caused by other devices, for example, if your neighbour was using the same Wi-Fi channel as you, the signals could clash causing disruption. Co-channel interference happens when multiple devices compete for time to transmit on the same channel. Adjacent-channel interference occurs when devices on overlapping channels try to communicate at the same time. Interference can slow down the transmission of data. The channels with the most interference are those that overlap with each other.
To improve performance and avoid interference, you can try switching the channel your network is using or move your devices to the 5 GHz band, which has 23 non-overlapping channels compared to just 3 on the 2.4 GHz band, as a general rule, we would recommend having your 2.4Ghz network on Channel 1, 6 or 11 and your 5Ghz between 38 – 54.
