If you have nearby neighbors with Wi-Fi, the local airwaves may be congested and, therefore, slow. Users have access to three viable 2.4 GHz Wi-Fi channels: channels 1, 6, and 11. If neighbors all use one channel, congestion is maximized. If neighbors spread out across the three channels, congestion is minimized.
While switching channel typically has a subtle effect on speed in normally uncongested rural areas, ensuring that you and your neighbors are not competing directly for limited local bandwidth prevents unnecessary interference where it matters most.
We used Mac OS to demo the process of changing Wi-Fi channels, but it’s virtually identical on Windows.
The above image shows the NetSpot default interface, ordered by channel. As you can tell, most networks operate on channels 1, 6, and 11, with a few networks operating outside the three most viable channels.
Otherwise, determine your router default IP address with a quick online search of your router manufacturer and model. Most manufacturers use the default address 192.168.1.1 for the majority of their models.
Once you’ve determined your default IP address, navigate to http://<default address> in your web browser. Example: if your default address is 192.168.1.1 go to http://192.168.1.1.
Note that there are another eleven channels, besides 1, 6, and 11, available in the 2.4 GHz frequency band. These channels are usually not viable because they overlap with each other, increasing interference. If, however, you live in either a very remote area (where interference on all channels is minimal) or a very congested area (where channels 1, 6, and 11 are overused) you may want to experiment with channels 2 through 4, 7 through 10, and 12 through 14.
