  • How to Choose the Best Wi-Fi Channel for Your Network

    Many home networks in the U.S. use routers that by default run on channel 6 on the 2.4 GHz band. Neighboring Wi-Fi home networks that run over the same channel generate radio interference that can cause significant network performance slowdowns. Reconfiguring a network to run on a different wireless channel helps minimize these disruptions.

  • Adjacent-channel interference - Wikipedia

    The adjacent-channel interference which receiver A experiences from a transmitter B is the sum of the power that B emits into A's channel—known as the "unwanted emission", and represented by the ACLR (Adjacent Channel Leakage Ratio)—and the power that A picks up from B's channel, which is represented by the ACS (Adjacent Channel Selectivity).


  • How to stop channel interference on 802.11x wireless ...

    Techniques to identify and reduce interference depend on the source. The most common source is co-channel interference from neighboring WLANs (including competition between your own two routers). When you configure a Wi-Fi access point (or router) to use a specified channel, the channel is centered within a frequency range that's about 20 MHz wide.


  • Meraki Auto RF: Wi-Fi Channel and Power Management

    2.4 GHz Channel Selection. Meraki access points follow best practices and industry standards in the Auto Channel selection, so APs' 2.4GHz radio will only be set to channels 1, 6, and 11.
