Why channels 1, 6 and 11?
Are you spending money for high-speed Internet and not getting what you expected? Was your Wi-Fi network working fine and now you're suddenly stuck with slow Wi-Fi data rates? Selecting the proper Wi-Fi channel can significantly improve your Wi-Fi coverage and performance.
In the 2.4 GHz band, 1, 6, and 11 are the only non-overlapping channels. Selecting one or more of these channels is an important part of setting up your network correctly. Currently, many wireless routers automatically select the channel for you upon initial setup, where depending on your wireless environment, it could lead to slow Wi-Fi speeds and interference. This article will describe what interference you're dealing with and takes you through the steps to selecting the right channel, so you can understand why you should choose between channel 1, 6, and 11.
The three main causes of Wi-Fi interference
Co-Channel interference isn't a major problem until there are too many Wi-Fi devices on the same channel. Adjacent-channel interference, on the other hand, is where you run into problems and channel selection becomes critical. Luckily, these channel related interferences can be reduced or eliminated by selecting the proper Wi-Fi channel for your network.
Using a spectrum analyzer like inSSIDer will allow you to see this wireless environment, so you can either select the right channel or mitigate Wi-Fi interference, ultimately improving your 2.4 GHz Wi-Fi network performance.
Get Reliable Wi-Fi at Home
For professionals working from home, students studying from home, and teachers teaching from home, reliable home Wi-Fi is part of what we need to get through our day.

Non-Overlapping Channels
Each channel on the 2.4 GHz spectrum is 20 MHz wide. The channel centers are separated by 5 MHz, and the entire spectrum is only 100 MHz wide. This means the 11 channels have to squeeze into the 100 MHz available, and in the end, overlap.
Channels 1, 6, and 11, however, are far enough from each other on the 2.4GHz band that they have sufficient space between their channel centers and do not overlap. While choosing channels 1, 6, or 11 will mean you have to share the channels with other networks (co-channel interference), it's a much better choice than dealing with adjacent-channel interference that occurs with all the other channels.
Armed with the above information, you've narrowed your selection down to three channel choices (1, 6 and 11) without using any software! Unfortunately, this doesn't mean neighboring networks aren't using non-standard channels. That's where MetaGeek can help out. Using inSSIDer with MetaGeek Plus, you'll be able to visualize every network within inSSIDer's reach, so you can finalize your decision. For more information about the types of channel interference, check out our Video Tutorials.
The benefit of using inSSIDer is that you can now see what is causing your Wi-Fi problems and fix them fast. inSSIDer will automatically recommend the optimal channel for you, and you don't need to be a Wi-Fi guru to use it. Just launch inSSIDer, and start out by counting how many networks are active on each channel. The first step is to click the "Channel" header to sort the channels in order. What you are looking for is the channel (out of 1, 6, and 11) that has the fewest networks present.
Notice in the above image that the network called "bba" is running on channel 9, which is overlapping channels 6 and 11. There is only one active network on channel 1, and its signal strength is very low. If you are deciding which channel would be the best for a new access point, channel 1 has the fewest amount of networks and there aren't any partially overlapping networks. In this example, the best channel to choose is channel 1.
