It also has a very narrow range of channels, usually between 1-11. Common household devices such as microwaves and cordless phones also use the 2.4GHz bandwidth, and can cause interference with your wireless network. As a result of its heavy usage and narrow range of channels, the speed and range of typical WiFi devices can be negatively affected. 5.0GHz solves this problem by providing a faster, less congested, bandwidth with a wider range of available channels.
