Wireless networking has transformed the world in a huge way over the past 15 years. Wireless technology has spread widely lately and you can get connected almost anywhere; at home, at work, in libraries, schools, airports, hotels and even in some restaurants.

Channel: translates as Channels
Wireless networking is also known as Wi-Fi or 802.11 networks because it includes the specifications specified in IEEE 802.11. The main advantage of Wi-Fi is that it is compatible with most advanced computer operating systems, smartphones, game consoles, and printers.
Despite the advantages, maintaining Wi-Fi speed continues to be a frustrating problem, which can be due to a variety of reasons such as a nearby interference, or the way your router is set up, or if you live in an apartment building or a private house, then separate your devices from routers etc. Even some other gadgets and electronics like cordless phones and Microwaves can interfere with Wi-Fi as well.
Fortunately, there are good ways to get fixed Wi-Fi speeds. If you are among those who have been able to mess around with your Wi-Fi router settings, you may have come across the only channel available to more than one user. It is proven fact that there are some channels that actually offer more speed than others.
Read on to learn more about 802.11 channels, interference, and the big differences between 2.4GHz and 5GHz Wi-Fi.
Channels 1, 6, and 11
Most modern Wi-Fi home routers broadcast at different frequencies. Home Wi-Fi networks utilize a narrow range of radio frequencies between 2.4GHz and 5GHz to transmit signals. Since the signal goes far and has the ability to penetrate through walls very easily, normally a 2.4 GHz is enough for large homes with multiple floors. However, 5 GHz is best to go for smaller homes, as it offers much faster speeds, albeit in a shorter range.
The distance between channels is really important as overlapping can lead to terrible wireless networks. Recent observations have highlighted that the use of 40MHz channels suffers due to congested waves. Although the band of 5GHz seems to be boosted by the introduction of 802.11ac in 2013, it appears as 2.4GHz still seems to be chosen for its compatibility as well as incumbent choice for users. due to their two radio routers as well as devices.
All versions of Wi-Fi up to and including 802.11n (a, b, g, n) operate between the frequencies of 2400 and 2500MHz. Similar to TV channels, this range has been distributed deeper into some smaller bands or channels. There are 14 channels allotted in the 2.4GHz range separated by 5MHz individually except for a 12MHz gap before channel 14. The signal range is negligible This is the main reason leading to the overlapping of channels and poor throughput on your wireless network.
Fortunately, channels like 1, 6 and 11 are spaced with enough spacing to ensure no overlap. You should always try to use channel 1, 6, or 11 on a non-MIMO setup (ie 802.11 a, b, or g). Furthermore, stick to channels 1, 6, and 11, if you use 802.11n with 20MHz channels. However, if you want to use the 40MHz channels, be aware that the waves can get very crowded, unless you are living in a single-family home in the middle of nowhere.
Which Wifi Channel should I use in an area with many Wifi routers?
Channels 1, 6, and 11 are your best choice for minimal interference and maximum throughput. But depending on other wireless networks in your vicinity, choosing other channels can also help in getting your hands on better speeds. For example, such tools can help you find the best and clearest channels. However, remember to use any different channels from channels 1, 6 and 11 that can make you aware of the reason for interference among other residents in your vicinity.
If you want maximum throughput and minimal interference, channels 1, 6 and 11 are your best bet. But depending on other wireless networks in your vicinity, one of those channels may be a better choice than the others.
For example, if you’re using channel 1, but someone next to you is annoyingly using channel 2, your throughput will drop. In that case you’ll have to change channel 11 to completely avoid interference (although 6 is pretty good too).You may want to use a different channel than 1, 6, or 11 – but remember friendwill be the cause of interference (and everyone over 1, 6, and 11 will beat you).
In an ideal world, you would talk to your neighbors and get all routers to use channels 1, 6, or 11. Bear in mind that interior walls do a decent job. good mitigation (weakening) a signal. If there is a brick wall between you and your neighbor, you can use channel 1 without affecting each other. But if it’s a thin wall (or has a lot of windows), you should use different channels.
There are tools that can help you find the most obvious channel, such as Vistumbler . But it’s probably faster to switch between channels 1, 6, and 11 until you find one that works well. (If you have two laptops, you can copy a file between them to check the data volume of each channel.)
What is 5GHz frequency?
The biggest advantage of 5GHz (802.11n and 802.11ac) is the availability of more free space and also high frequency access. Both 802.11n and 802.11ac can provide 23 non-overlapping 20MHz channels. It may be a good time to switch to 802.11n wireless technology if you are among those who are still dependent on 802.11b and g. This new router has the necessary hardware but also the ability to select as well as alter the appropriate channels for maximum output with minimal interference. If you are using the 5GHz band, and are in an area with thick walls, you should expect less interference and faster channels like 40, 80, and 160MHz channels.
Choosing the right channel will most likely become a thing of the past, as everyone eventually upgrades to newer hardware and moves towards 5GHz. However, channel tuning on the router may still be required. We need to be ready to deal with future changes in wireless networks in hopes of higher frequencies and new adaptive antennas.
How to change Channel for Wifi
You access the Wifi Router management address, usually setting the Channel it will be in the Menu Wireless -> Settings
You just search for the same and it will come out and change according to the Channel settings I mentioned above
