Microwave ovens use electromagnetic waves of 2.4 GHz to heat food. Traditionally, this type of equipment does not use Wi-Fi and uses the entire frequency band without any regard to other communication on the same frequency. Baby Monitors, Walkie-Talkies and Other Radiosĭo you have baby monitors, walkie talkies, or maybe a radio locator to keep track of your pets or keys? Such equipment tends to use the same frequency as the older Wi-Fi standards 802.11 b/g/n and will therefore interfere with the 2.4 GHz band. Old devices and computers in particular will need several seconds to reconnect if the access point changes to a different channel. Worst case, your Wi-Fi access point will automatically change the channel to avoid the interference – a misguided strategy, as Bluetooth will hop through all the channels that are used for Wi-Fi anyway, and this may cause you to lose more Wi-Fi traffic. As it jumps so often, actual impact on Wi-Fi will be highly variable, making such scenarios rather hard to troubleshoot. When equipment that uses Bluetooth, jumps into the frequency range of equipment that uses Wi-Fi, it can therefore ruin some of the Wi-Fi traffic and create delays. Bluetooth uses a technology called frequency hopping, which means it skips around the 2.4 GHz band, up to 1600 times per second(!) Wireless devices such as headsets, keyboards, and mice can interfere with the Wi-Fi signals. If you need to have logins for the wireless network with different access levels, we recommend setting up a guest network with its own network name (SSID) on the same router or access point as the primary network. If you have multiple wireless networks in your home that are set up on different pieces of equipment – this can be even more disruptive than your neighbor's network. Separate Wireless Networks in Your Own Home How to find good Wi-Fi channels and bad neighborsĢ.For equipment on the 2.4 GHz band, neighboring networks are the single largest source of interference on the wireless network. When many networks are located closely together, for example in apartment buildings, this will affect the wireless capacity.
