Slow WiFi: Fix it by changing your router’s channel
Are you experiencing slow WiFi speed then there are chances are your neighbor’s WiFi network is causing this problem. Now don’t go and fight with your neighbors, the reason may be technical and can be fixed without violence! Let’s understand why your neighbor’s WiFi network might be slowing your WiFi connection or simply say multiple WiFi(s) in close range are responsible for this.
WiFi or wireless networks generally use 2.4GHz and 5GHz bands and these bands are divided into parts or channels to transmit information over radio waves. 2.4GHz band has 14 channels and 5GHz band has 23 channels. Mostly 2.4GHz band is used by WiFi, every wireless network works on a particular channel and out of 14 channels 1, 6 and 11 is used the most by routers. Learn an important thing here, the 2.4GHz band has higher range than 5GHz and can easily penetrate walls and obstacles. But range of 5GHz (5G Technology) band is less and signals can lost to any physical obstacles like buildings. However it offers extremely high speed, 10 times more speed than 2.4GHz band.
So, it is highly possible that your nearby WiFi routers are also working on the same channel. When multiple WiFi networks in close range work on same channel it is obvious that their signals will interfere with each other. As a result you may experience slow WiFi, signal drop or speed issues. So, the simple solution here is to use those channel which is used by none or by least routers or move to 5GHz band which has higher number of channels but may not penetrate through walls easily. But the now the question is how will we find which channel is best for our network. Don’t worry we will help you in finding the empty channel or least congested channel and fix your slow WiFi.
