Each channel is spaced <strong>5 MHz apart<\/strong>, but the actual bandwidth of a channel is <strong>approximately 22 MHz wide<\/strong>. This means adjacent channels <strong>overlap<\/strong> with each other, leading to interference if nearby networks are using overlapping or nearby channels.<\/p>\n\n\n\n<p>In your case, the neighboring Wi-Fi network is set up at <strong>2.412 GHz<\/strong>, which corresponds to <strong>Channel 1<\/strong>. To minimize interference, it is important to choose a channel that is <strong>non-overlapping<\/strong> with Channel 1.<\/p>\n\n\n\n<p>In the 2.4 GHz band, the standard <strong>non-overlapping channels<\/strong> are:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Channel 1<\/strong> (centered at 2.412 GHz)<\/li>\n\n\n\n<li><strong>Channel 6<\/strong> (centered at 2.437 GHz)<\/li>\n\n\n\n<li><strong>Channel 11<\/strong> (centered at 2.462 GHz)<\/li>\n<\/ul>\n\n\n\n<p>These three channels are spaced far enough apart (by at least 25 MHz) to avoid overlapping with each other. Therefore, if a neighboring Wi-Fi network is already using <strong>Channel 1<\/strong>, the best strategy to minimize interference is to use <strong>Channel 6<\/strong> or <strong>Channel 11<\/strong>.<\/p>\n\n\n\n<p>Choosing either Channel 6 or Channel 11 depends on other nearby networks. If possible, perform a Wi-Fi scan using a network analyzer tool to see which of these two channels has less congestion. However, <strong>either choice will be better than staying close to Channel 1<\/strong>, such as using Channels 2 through 5, which partially overlap and still interfere.<\/p>\n\n\n\n<p>In conclusion, <strong>Channel 6 or 11<\/strong> are your optimal choices for reducing interference from a neighbor\u2019s network on Channel 1, improving both <strong>signal quality<\/strong> and <strong>network performance<\/strong>. This is particularly important in dense residential areas where multiple overlapping networks can severely affect wireless performance.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>&#8220;A neighboring Wi-Fi network has been set up at 2.412 GHz.
