A lot of people don’t know, how to find empty channel and choose it for your wireless router. It’s not strange! Need to change channel appears in many people because of a lot of noise on current channel, which causes slow data transfer and lower signal strength.

Sometimes problems with channel can cause invisibility of wireless network in device’s WiFi network list. In this article I would describe you why this happens and how channel can be changed.

What is WiFi channel and what reasons to change it?

Nowadays, most of the routers use 2,4 GHz frequency. New modern routers usually use 5 GHz frequency. Modern routers are more expensive, so that’s the main reason of first type router popularity. For 2,4 GHz routers number of channels is limited. When there are more than one networks use the same channel, there will be some interference.

If you live in apartment block, you will deal with this trouble. For example, you have several neighbors and you set 4th channel for your wireless network. A big chance that someone from neighbors will set the same channel and this causes negative things mentioned above.

If you check router’s configuration page, you will see that network’s channel is chosen automatically after router enabling. Router tries to use the emptiest channel. Rebooting can be used to change channel, so better to leave automatic channel choice instead of manual choice of static channel.

inSSIDer and WiFiInfoView applications were made for people, who decided to set router channel manually and want find empty channels. We would show you how to use these applications, but don’t forget that network troubles can be caused not only by channel fullness, but by router power supply, noises from other devices, component problems, etc.

How to use inSSIDer or WiFiInfo View?

Open wireless network list on your device. If there are a lot of networks, it means some of the channels are too full. inSSIDer and WiFiInfoView applications were made to help people find the emptiest channels. Both of them are empty and not very difficult for people, who can follow instruction steps. So let’s find out how you can use these apps.

Channel column show us what channel is used by current network. Find the emptiest channel. Channels 1, 6, 11 don’t intersect, so if one of them is empty, better to use it. In some lines you can see 2 channels selected (only for 2.4Ghz). That’s because of frequency range by default is set to 40 MHz, so network takes one more channel. It can be set to 20 MHz manually. After that, your network will use only one channel.

WiFiInfoView

WiFiInfoView is very simple application. It’s not important to install for usage. Just download it from software share website. Unzip archive and launch exe file. Program will start after that.
