WiFi Channel Picker allows you to easily choose which channel your router uses, the goal here is to provide a more stable signal while surfing the web within a high usage area (neighborhoods, apartments, etc.).
The 2.4GHz band (the radio band most commonly used by WiFi) is divided into 11 (usable) channels. The most spaced out channels within the 2.4GHz band is the channels 1, 6 and 11. These channels hardly show any overlap. Always stick to one of these three channels, even if they are crowded!
While WiFi access points have great difficulty handling signals coming in over different channels, they can deal with signals coming in over the same channel, via a mechanism called CSMA/CA. So, let's say that you and your neighbor are both on channel 1. Now each access point waits its turn to handle the signal coming in over channel one. Although the bandwidth for both you and your neighbor is compromised, both of you will have a reliable speed -- all the time. And remember that the bottleneck in your connection with the internet is probably not your WiFi Access point, but the connection of your WiFi access point with your provider. Simply put: if your connection with the internet is on average 50 Mbps, and your WiFi offers 150 Mbps to your laptop, half of which is crowded out by your neighbor because you share the same channel, you have still plenty of bandwidth left to handle all traffic coming from the internet. In other words, in this set up you won't even notice your neighbor exists.
So, picking the 'right' channel can, in light of these criteria, be a bit of a challenge. Of course, there's no need to figure all this out yourself. Let our WiFi Channel Picker do it for you! It's free, and it's easy to use. Just download it and run it. It will tell you which channel to use.
