Each channel is being used by multiple routers. In the 2.4 GHz graph, channels 1, 6, 9, and 11 are being used. In the next two images, the white lines help us see what channels are being used. For this article, we’re using Wi-Fi Analyzer on Android. To do that, you’ll need a good Wi-Fi analyzer app. Let’s check and see if your Wi-Fi problems might be channel-related first. How Do I Know If I Should Change My Wi-Fi Channel?ĭon’t change your Wi-Fi channel for no reason. When further away from the router and the quality of the 5 GHz frequency drops, the device will jump to the 2.4 GHz frequency so it can stay connected. When closer to the router, the device will jump to the 5 GHz frequency. By having both bands, you have greater Wi-Fi coverage and a better signal closer to the router. A higher frequency means good quality signal, but not as much range. Why, though? A lower frequency means the signal travels farther, but the quality isn’t as good.
In the 5GHz range, there’s a 0.010 GHz difference between neighboring channels. You’ll see this in some instructions below. Each channel is 0.005GHz different from its closest neighbors. For 2.4 GHz, the frequencies can range from 2.400 GHz to 2.499 GHz. Within those bands, the router broadcasts at slightly different frequencies. The router broadcasts at 2.4 billion or 5 billion cycles per second. Hopefully, these tools will allow you to fully see what devices. The app also has other tools that you can use to scan specific devices on the network to get more information. As the scan progresses, you’ll see the ports that are open and active and also which ports are blocked. The Wi-Fi signal moves through the air as a wave. Tap on Ports, choose Common or All and then tap Start at the top.
A hertz is the unit to show cycles, or waves, per second. Wi-Fi routers broadcast at two different frequency bands: 2.4 GHz and 5 GHz. If you just want to change the channel on your router, keep scrolling. This can even give them access to the files on your computer or mobile devices that are connected to the Wi-Fi network. If you want to learn more about Wi-Fi channels, read on. An unprotected wireless network (or Wi-Fi connection) and can expose you to risk as hackers can use this connection to access any data you are sending over this (so basically anything you’re accessing and inputting on the Internet).
How to scan wifi channels to find best one Bluetooth#
Microwave ovens, cordless phones, even Bluetooth devices could be using the same channel.Ĭhanging your Wi-Fi channel can mean better download speeds, less lag when gaming, and greater range. Anything that emits a radio frequency can cause interference. It’s not just other Wi-Fi routers to consider.
