How to Make the Best Wi-Fi Setting?
Best Wi-Fi Setting: Although your internet provider offers the best bandwidth that your line supports, sometimes it is up to you to fine tune the modem to get full efficiency. Nowadays, when mobile is dominated, wired connections are no longer preferred.
With the development of Wi-Fi standards and the widespread use of 802.11ac modems in the 5 GHz band, wireless networks have reached the level of capturing the performance of wired networks. We answer this question in our best Wi-Fi setting guide.
How to make the best Wi-Fi setting?
So, what do you need to do to use the wireless network with full efficiency? Should I use the modem in automatic settings or fine tune it? Before moving on to our guide, it is useful to take a look at some fine and important information.
We have two fine adjustments that we need to know in order to get the speed we receive from our internet service provider with the highest quality via wireless connection. The first is to provide the correct Wi-Fi channel setting selection. Let’s lighten the issue of channel tuning, which is the most confusing part, as much as we can. As we know, we are currently using modem or router devices using the 802.11ac and 802.11n standard, using the 2.4 GHz and 5 GHz band.
The importance of 1,6 and 11 channels
There are multiple channel settings in your router’s settings. Most routers have channel settings set to “Auto”, but if you look at the list, there are a dozen Wi-Fi channels. So how do we know which Wi-Fi channels are faster than other channels on this list? Choosing the appropriate Wi-Fi channel can significantly increase your Wi-Fi coverage and performance. But even if you find the fastest channel there, it does not mean that you should choose it immediately.
Various frequency bands ( 2.4 GHz, 3.6 GHz, 4.9 GHz, 5 GHz and 5.9 GHz ) have their own channel ranges. Usually routers use a total of 14 channels 2.4 GHz band, but in reality there may be 13 or fewer channels used worldwide.
All Wi-Fi communication through 802.11n (a, b, g, n) operates between channel frequencies of 2400 and 2500 MHz. This 100 MHz difference is divided into 14 channels, each 20 MHz. Consequently, what is intended to be explained in the diagram above is that each 2.4 GHz channel is overlapping with two to four other channels. The conflict makes the wireless network efficiency quite weak.
The most popular channels for 2.4 GHz Wi-Fi are 1, 6, and 11 because they don’t overlap. In an installation without MIMO (Multiple-Input and Multiple-Output), that is, you should always try to use channels 1, 6, or 11 with the width of 802.11 a, b or g.
– What is MIMO: It is a radio term meaning multiple inputs and outputs. It is used to increase the performance of the connection by using more than one antenna on the transmitter and/or receiver side.
As we mentioned above, every wireless channel with a frequency of 2.4 GHz is 20 MHz wide. When using 802.11n with 20 MHz channels, select channels 1, 6 and 11. If you are going to use the 40 MHz channel and do not live in a very large house, keep in mind that frequency waves may be clogged.
Three main causes of Wi-Fi interference
Reason 1: Common Channel Interaction
On networks where devices are communicating sequentially, it takes time for each to wait for their turn. Therefore, device standby time is extended. This type of Wi-Fi interference is not actually electromagnetic interference. Instead, we can explain it as the temporary suspension of Wi-Fi routers from other devices for transmitting data.
Reason 2: Adjacent Channel Initiative
Adjacent channel scrambling occurs when clients in overlapping channels span simultaneously. Wi-Fi channel selection is very important in such situations. Such channel-related interventions can be interrupted or excluded by choosing the appropriate Wi-Fi channel for your network.
Reason 3: Wireless-free interference
In addition to Wi-Fi routers, there are many other electronic devices that can interfere with the 2.4 GHz band. Some; It intervenes because they use it to wirelessly transmit data such as security cameras, Bluetooth devices, baby monitors, and smartphones, while others interfere because they emit large amounts of electromagnetic radiation, such as microwaves and other devices.
To prevent interference without Wi-Fi, it is important to put your Wi-Fi router away from all sources of electromagnetic radiation, preferably away from walls, large furniture and similar solid objects.
How to use high speed 5 GHz band efficiently?
The 5 GHz (802.11n and 802.11ac) band actually offers more free space at higher frequencies. At this frequency, 23 MHz 20 MHz channels are offered. Starting from 802.11n to 802.11ac, wireless technology has become much more advanced.
If you have purchased a Wi-Fi router in the past few years, you probably have a good 802.11n or 802.11ac router. Many of these modems or routers have hardware that automatically selects the appropriate Wi-Fi channel and adjusts the output power, thereby increasing efficiency and reducing interference.
