Wi-Fi network heat map

Most of us have struggled at some point to find the best spot in our home or office where we can expect the strongest Wi-Fi signal. Did you know that you can increase your Wi-Fi speed by simply selecting the right Wi-Fi channel on your Wi-Fi router? Yes, there are groups, there are channels. Are you confused? Leave him alone. We break down the steps to unlock the best possible internet speeds already available through your router.

If we encounter areas where the connection to our WLAN only works sporadically, the first thing we try is to move closer to our WLAN router or reboot it if necessary. In most cases, these attachments do not improve the speed or strength of our connection. What works when you change the router settings? Now, most of us don’t bother to connect to our router and leave it in the factory settings as you purchased it. However, a little knowledge about choosing the right channel and range for Wi-Fi can greatly improve the performance of your network.

What is the frequency range?

Frequency bands are the bands of radio waves used to transmit data. The publicly available bands are 2.4 GHz and 5 GHz. These bands are used for data transmission in the wireless spectrum. There are Wi-Fi MAN standards; 2009 saw the introduction of the Wi-Fi 802.11n standard, which operates in both the 2.4 GHz and 5 GHz frequency bands. The groups are then divided into channels.

What is a chain?

There are several channels in each frequency band. The 2.4 GHz frequency channel has z. B. 14 channels. Each channel is 20 GHz wide, and 2.4 GHz is only 100 Hz wide. So you can imagine how busy the 14 channels in this frequency band are. Where is this going? This results in overlapping bands, causing interference if your router is in these overlapping paths. For example, only three 1,6 and 11 of the 14 channels do not overlap. On the other hand, 5 GHz offers much more space and 23 non-overlapping 20 MHz channels.

What should I choose – 2.4 GHz or 5 GHz?

Both frequency bands have advantages and disadvantages. Just because there are more bands available, without overlap, in the 5 GHz range does not mean it is automatically better. You’ve probably heard of dual-band routers; what does that mean? If you purchased your router in the last few years, you probably have both frequency bands configured. This allows you to operate the 2.4 GHz and 5 GHz channels simultaneously. 5.0 GHz is faster, but 2.4 GHz goes further. This means that 5.0 GHz is not as effective at penetrating walls. For example, if you have a multi-story home, you may get better coverage in remote areas of your home if you are on 2.4 GHz, but it may be less than 5.0 GHz. As mentioned earlier, the operation of both devices offers the best of both worlds.

What is signal interference?

All Wi-Fi’s are affected by radio frequency interference. The risk of interference from Wi-Fi channels increases if the router is an older model and only supports the 2.4 GHz frequency band. There are three types of signal interference.

  • Single Channel Interference – This type of interference occurs when all other Wi-Fi devices use the same channel; for example, you and all your neighbors on channel 6.
  • Neighbor Channel Interference – This type of interference occurs when you and your neighbors overlap and overtake each other.
  • Non-Wi-Fi Interference – Many electronic devices can cause interference. B. Surveillance cameras and baby monitors. Microwaves can also seriously affect Wi-Fi performance if the Wi-Fi router is too close to the microwave.

How do I know how much bandwidth my router uses?

You must enter your router settings. If you have Linksys or Netgear, try in your browser, and for TP-Link, try Use the administrator’s credentials and log in. Navigate to advanced settings and Wi-Fi settings. If you have a dual-band router, you will see two settings, one for 2.4 GHz and one for 5 GHz. When described in one of the submenus, the selected channel is shown below.

How do I change the Wi-Fi channel?

Navigate to the same location as the advanced router settings above. You can have auto tuning for your channels, but you should be able to select the desired channel from the drop-down list. Another thing to keep in mind is that when you reboot or turn off the router, the Wi-Fi channel may be selected differently when the router appears on the screen. So make sure it’s a permanent framework.

What is the best Wi-Fi channel for 2.4 GHz and 5 GHz?

To determine the best channel for 2.4 GHz and 5 GHz, it is always a good idea to choose a radio channel that your neighbors are not using. In addition, it makes sense to choose the channel that is least disturbed. It’s always a good idea to choose between 1.6 and 11 in the 2.4 GHz band. Meanwhile, 40, 80 and 160 MHz are the best choices for the 5 GHz band. If you do not test the channel used by your router and the channel used by your neighbors or other devices, you cannot make an informed decision.

To find the best Wi-Fi channel (with NetSpot)

It would be helpful if you have a Wi-Fi network analyzer to determine which channels to select. Of all the Wi-Fi channel analyzers, NetSpot is one of the best available. You can install it on your Windows laptop or even on your Android smartphone. NetSpot helps you visualize your channel mapping and you can immediately decide which channel to choose. As you know, routers operate in the 2.4 GHz band, channels 1, 6 and 11 are different channels that do not overlap.

If you know these channels and have some technical talent, you can use these channels. It may turn out that even these non-overlapping channels overlap. These few users may cause interference. If you choose the right channel with the world’s best Wi-Fi channel analyzer, the risk of poor Wi-Fi reception is very low.
