Best WiFi Channel for 5GHz (20/40/80 MHz): Which Channel for 2.4GHz and 5GHz WiFi?

Best WiFi Channel for 5GHz (20/40/80 MHz)

I know you like getting a fast internet connection. Who doesn’t? That is why we need to know which is the best WiFi channel for 5GHz between 20, 40, or 80 MHz. You also do not want dropped connections for your devices.

The best channel for 5GHz depends on the channel width where we recommend using either 40MHz or 80MHz for the best internet speed and minimal interference. For users on the 20MHz channel width, you have so many options including 36, 40, 44, 48, 149, 153, 157, 161, and 165 channels. For 40MHz, you can use channels 36-40, 44-48, 149-153, or 157-161 thus no overlapping and for 80GHz you can choose 36-48 or 149-161. For the 2.4GHz WiFi band, we only recommend 20MHz as the channel width with the best channels for 2.4GHz being 1, 6, and 11.

Improving Wi-Fi connections for everyone in your home is the ultimate goal. My home is always a cranky place when the internet is down.

Ensuring that you get the best 5 GHz channel is important for an excellent connection. The best thing about the WiFi channel width for 5GHz is there is less interference as compared to 2.4GHz.

Thus, it means setting the highest WiFi channel width for the 5GHz band will give you exceptional performance if there are no devices or other routers in your vicinity. However, if there is any device or AP in the same channel, then you can’t bond the channels together and get higher internet speeds since the WiFi speeds will drop significantly.

Thus, we recommend increasing the 5GHz channel width if you are at home which is not in a densely populated area like apartments, or have no other WiFi units in your home since they can also interfere with WiFi.

Thus for the 2.4GHz band, changing the WiFi channel width can lead to interference. Therefore, you can stick with the 20MHz. This is one of the main differences between 2.4GHz and 5GHz WiFi bands.

Best WiFi Channel for 5GHz (20/40/80 MHz)

The best WiFi channel width for 5GHz is the 40MHz channel for the fastest and most stable 5GHZ band WiFi speed and device connection. You can also use 80MHz channel width if there are no routers in the vicinity as this would increase the interference.

The 20 MHz, 40 MHz, 80 MHZ, and 160MHz are all good choices. However, the choice of channel width will be dependent on the following:

  • The Wi-Fi speed/ bandwidth required
  • The number of devices to be connected
  • How sparsely located are the devices in your home
  • The level of interference in the Wi-Fi channel if they are wider

The following are the best channels when using 20MHz, 40MHz, or 80 MHz as the WiFi channel width for your 5GHz band:

20 MHz channel width40 MHz channel width80 MHz channel width
Channel 36Channels 36 through 40Channels 36 through 48
Channel 40Channels 44 through 48Channels 149 through 161
Channel 44Channels 149 through 153
Channel 48Channels 157 through 161
Channel 149
Channel 153
Channel 157
Channel 161
Channel 165

More channels mean better connectivity but we must not forget that wide channels are also available with a 40 Mhz channel width. You can choose between 20Mhz,40Mhz, or 80MHZ depending on your needs.

Wide channels provide a stronger signal and less interference from other networks in your area. This means you can enjoy faster speeds and greater coverage than ever before! Plus, it’s easy to set up – just choose your desired frequency and enter your password or keyphrase into our app or web portal.

If you want more than one device to be able to connect at once then go with a higher frequency like 80MHz which will give you more bandwidth and less interference from other devices in your area.

But if you only need one device connected at a time then go with lower frequencies like 20MHz or even 10MHZ which will provide less interference from other devices in your area but it may take longer to find an open connection when there are many people using Wi-Fi around you because of its low-frequency range.

Which is the best channel width for the 2.4GHz band between 20MHz and 40MHz?

How to choose the best WiFi channel for 2.4GHz or 5GHz WiFi

The 20 MHz channel width is recommended because it allows more channels to be used and less interference. With a 40 MHz channel width, all devices would talk in the same channel and cause too much noise.

The 20 MHz channel width is recommended because it offers more channels than the 40 MHz channel width, and thus less interference between devices. If a device talks in one of the three 20MHz channels (1, 6, or 11) then there will be less noise from other devices talking on different frequencies.

This also means that if a device has an issue with one of these three channels, it can still talk on another frequency without causing too much interference.

What is the best channel for 2.4GHz WiFi?

For the 2.4GHz WiFi band, we only recommend 20MHz as the channel width with the best channels for 2.4GHz being 1, 6, and 11.

The 2.4GHz WiFi band is used by more than half of all wireless devices around the world. It’s also the most crowded channel. This means it can be difficult to avoid interference and an inadequate signal.

On top of that, some 2.4GHz devices are unable to connect or have a very weak connection on this band because they use less bandwidth and can’t take advantage of the wider range offered by the 5GHz WiFi band.

You’ll notice from your router that there’s a default channel for both bands listed, but if you’re experiencing any difficulties with connectivity, you may want to switch to a different channel so that you have better luck avoiding interference and maintaining a strong signal.

The 5GHz WiFi band has 23 channels to choose from (1-23), which means less chance for interference and more channels available for you to use.

What is Wi-Fi?

Wi-Fi is a wireless technology that allows your devices to connect to the internet. It’s like a bridge between your computer and the internet. The best way to think about it is as something in between your device and the internet.

Wi-Fi is a wireless technology that allows you to connect your devices to the internet without wires. It can be used in many different ways and has become an essential part of our daily lives.

With so many benefits, there are plenty of reasons why you should know more about this amazing technology.

What are Wi-Fi bands?

There are two types of Wi-Fi bands 2.4GHz and 5GHz. They have different frequencies, which means they can be used in different ways.

Well, there’s a lot of information out there on this topic, but we’ll give you the basics in just a few sentences.

Let’s start with the 2.4 GHz band – that’s what most people use today when connecting their devices to wireless networks at home or work. It has slower speeds than 5 GHz, but it can reach farther distances because of its wider range of frequencies (2.4 GHz vs 5 GHz).

The 2.4GHz band is mostly used for connecting to the internet wirelessly from a device like your laptop or tablet, while the 5 GHz band is more often used for devices that need to transfer large amounts of data quickly like streaming video on your TV or downloading files from a network drive at work.

If you want faster speeds for downloading or uploading files like videos or music from the internet, you should use a 5GHz band instead of a 2.4GHz one (although there are some exceptions).

And if you live in an area with lots of people using wireless networks nearby, you might find that 2.4Ghz will work better than 5Ghz because it has less interference from other signals on its frequency range, meaning fewer dropped connections!

And then there’s the newer generation – 802.11ac Wave 2 which uses both 2.4 and 5GHz frequency bands for faster speeds and better coverage indoors and outdoors!

That said, if you’re looking for fast speed without sacrificing distance, try the newest product line called “Wave 3” which offers up to 1 Gbps download speeds over an even larger range!

What is 5GHz Wi-Fi?

5 GHz Wi-Fi (also called high frequency or high band) is a term that refers to the frequency at which wireless routers operate. The technical name for 5GHz Wi-Fi is IEEE 802.11a/n/ac. It’s often used in place of 2.4 GHz (802.11b/g/n) because it offers much faster speeds and less interference with other devices in your home or office.

What are the benefits of 5GHz Wi-Fi? 1) Faster speeds: Twice as fast as 2.4 GHz, capable of up to 1 Gbps download speeds 2) Less interference from other devices: Due to its higher frequency, signals from other electronic devices like cordless phones, microwaves, and baby monitors don’t interfere with a 5GHz signal.

The 5GHz frequency is often used for WiFi connections because it has much less interference and can cover a wider area than the more congested 2.4GHz band.

However, it has a shorter range: Up to half as far as 2.4 GHz, making it better for smaller homes and offices. However, 5GHz signals don’t travel as far as those from 2.4GHz because they have shorter wavelengths.

This means that, if you want to cover a large home or office, you should use two access points with the same channels in the 2.4GHz band and one in the 5GHz band (or one access point in each band).

There are also other factors that may affect your WiFi signal coverage such as walls, doors, and floors. For example, thicker walls will absorb more of the signal and prevent it from traveling through or out of the room where your wireless router is located.

We all know how frustrating it can be when we get no WiFi coverage on our phones due to a lack of signal strength.

Have you ever been in a crowded room and had trouble connecting to the Wi-Fi?

Wi-Fi channels are a range of frequencies that can be used for electromagnetic waves.

The 2.4GHz and 5GHz bands operate in the frequency range, which is also used by other devices for communication between devices. Wi-Fi signals are transmitted in channels that are smaller sections on the frequency range on these frequency ranges.

You should know about these frequencies so you can make sure your device is communicating with others on the same channel or not interfering with them at all.

There are 11 different Wi-Fi channels. This is because the 2.4GHz and 5GHz bands operate in a frequency range that is also used by other devices for electromagnetic wave use. This means that the channels will be important for communication between devices, so it’s best to find out which channel your router is using before you start connecting any new devices to it.

You can find out what channel your router is on by checking its manual or contacting customer service at your internet provider (or even just searching online). Once you know this information, make sure all of your wireless connections are set to the same channel as well! It’ll help keep everything running smoothly and interference-free.

Channels are important for communication between devices. This means that if your device is on one channel, but there are other devices on another channel, then it will be difficult to connect with them. It’s best to choose channels that have few or no overlapping frequencies so as not to interfere with each other.

Which are the Wi-Fi channels?

The 2.4GHz has 14 channels while the 5GHz offers 23 non-overlapping 20MHz channels. The 2.4GHz band has the following bands. The following channels overlap thus meaning that some frequencies are part of more than 1 channel. For example, 2420 lies between 4 channels.

Wi-Fi ChannelLower Limit (MHz)Upper Limit (MHz)Wi-Fi band

It is important to note that when data is transmitted through overlapping channels, there may be a slow down in internet speed because there is interference. However, there are a few channels with the least interference including channels 1, 6, and 11.

For most of the routers and devices at home, their default channel is Channel 6. This is because it has one of the least interference among the 14 channels.

The router channels operate in widths as shown above. Most of the channels are overlapping in the table above.

The width discussed in the table below is 20MHz even though we may find that the difference between the upper limit and the lower limit is 22MHz.

You can determine the width of your channels. This is because the routers have a property called channel bonding. The channel bonding enables the router to aggregate a number of channels for a wider stream for information exchange.

What is channel bonding?

Channel bonding, also called channel aggregation or carrier aggregation, is a technique that allows two or more channels to be combined in order to increase the bandwidth and data rate.

This can be done by combining multiple 20MHz channels into one 40MHz channel for example. The ability of a router to aggregate channels varies depending on the hardware design and firmware features.

It allows you to combine two or more channels together, doubling or even quadrupling the available bandwidth for your wireless devices. You can even combine four 20MHZ channels into one 80MHZ channel or 8 channels to 160MHz channel!

If you’re looking for faster speeds and better performance on your home WiFi network, then it might be time to consider adding some channel bonding!

If you want your network connection speeds to go up then you need an aggregated router. With an aggregated router, you’ll get faster downloads and uploads as well as better latency times which will make it easier for gamers and video streamers alike.

You’ll have less lag time with this type of setup because there’s more bandwidth available at any given moment in time. And if you’re looking for even higher speeds than what’s offered by a standard cable modem then check out our gigabit routers!

They offer download speeds up to 1000Mbps so they’re perfect for high-bandwidth applications like streaming HD video or playing online games with your friends from all over the world!

How to change the channel width on the router

How to change the channel width on the router

Are you looking to change the width of your router? You’ve come to the right place.

Changing the channel width is a simple process that can be done in just a few minutes. It’s an easy way to boost your wireless signal and get better performance from your Wi-Fi. You won’t have any more dead zones or buffering problems with this quick fix.

The first step is logging into your router. Once logged in, head over to Wireless and click on Basic Settings. From there, select Channel Width from the dropdown menu. Choose a channel width that best suits your needs and enjoy.

These steps may vary from manufacturer to manufacturer and thus we will offer the general guide below:

Steps to change the channel width on the router

Thus you can follow the following steps:

  • Using the private IP address login into the router. The IP address is indicated on the router’s box or on the manufacturer’s website. The default router IP address is,,, or as indicated on your router.
  • Type the IP address on the address bar of your browser. You should do this on a computer connected to the router via Ethernet connection or Wi-Fi. This will bring a login page.
  • On the login page, enter the admin username and password. The action will give you access to the web user interface.
  • On the user interface, click ‘Wireless’. Then go to the ‘Basic Settings’ option that is found under the wireless settings.
  • In this area, you will need to locate the channel width dropdown. Click on it and select the desired channel width between 20Mhz, 40MHz, and 80MHz options for most routers.
  • After selecting the desired channel width, click on ‘Apply’ or “Save’ depending on the router.
  • To apply the settings change, reboot the router safely

With these steps, you will have successfully changed the channel width for your router. Note that this process can be repeated and you can thus change the width back to the default option when required.

Finally, you will need to give your router a few minutes to apply the settings change and communicate with the connected devices!

Do I choose the “auto” option for channel width choice?

Setting the channel width is a crucial step in getting the best Wi-Fi connection.

You want to make sure that your Wi-Fi signal reaches all of the corners of your house or office without any dead zones. And if you have multiple devices in different rooms, then choosing a wider channel means less interference between them and better performance overall.

The dropdown list on changing the width for your router might also offer you an auto option for the channel width. This is because some of the best routers have set protocols that enable your router to choose the best WiFi channel width for your 5GHz or 2.4GHz depending on the environment.

You can leave the option as “auto” if you are not a tech enthusiast. However, for me and other tech enthusiasts, we love being in control of the router. Thus we choose a custom value for the channel width.

The Benefits of 5GHz WiFi

The 5GHz WiFi band has a larger bandwidth than the 2.4GHz band. This means that it can carry more data, which is particularly useful for devices such as gaming consoles and HDTVs.

This also means that there’s less channel overlap. So more devices can use the internet at once even though they are all emitting electromagnetic waves.

However, you’ll have to be more strategic about where you place your wireless router to ensure an adequate connection. This is because 5 GHz WiFi has a shorter range and rarely penetrates thick walls.

The 5GHz WiFi band is an alternative to the 2.4GHz WiFi band, which most devices operate on today. The 5GHz WiFi band is newer and has more bandwidth, so it can handle more data and doesn’t get crowded. This makes it perfect for gaming and HD streaming because less interference means you have a more reliable connection.

Best 5GHz channel FAQs

Which 5GHz bandwidth is best?

40MHz is the best channel bandwidth for the 5GHz band. It offers excellent WiFi speeds, the least interference, and ensures the router can connect to multiple devices. However, if there are no routers in the near vicinity, you can consider using the 80MHz channel on your 5GHz band.

Which 5GHz channels do not overlap?

No 20 MHz channels partially overlap. It is important to make sure that you keep the same channel cells touching in the 5GHz band because no 20 MHz channels partially overlap. In addition, there are 24 non-overlapping channels for your router so making this easier can help avoid interference with other routers or WiFi devices nearby and give better performance overall!

Are higher 5GHz channels better?

The best channel to use is the lowest possible one that your router supports when you want to penetrate walls or a higher channel when you have a clear line of sight (no obstacle between the router and your devices). Lower frequencies penetrate walls more easily and there’s a significant difference between 36 (5180) MHz and 165(5825). However, you can try different channels within the various 5Ghz bands and see which gives a better signal. Then choose the lowest channel in that band. Furthermore, until 2014 you couldn’t go much below 25MHz without risking interference or worse- an increase in power loss!

Is 80MHz better than 40MHz?

If you want to send more data over each channel, go with the higher frequency of 80MHz. However, you get fewer channels with 80MHz as compared to the 12 non-overlapping 5MHz channels for 40MHz. For your home router, you can use 40MHz channel bandwidth on both 2.4GHz and 5GHz. However, there is less interference from other sources which means faster speeds on wireless networks where bandwidth matters most!

Which is the best channel for 2.4GHz?

For the 2.4GHz frequency band, there are only 3 recommended non-overlapping channels. These are Channels 1, 6, & 11. This is unlike the 5 GHz band which has several non-overlapping channels. Moreover, you can only use the 20MHz channel width on the 2.4GHz frequency band.
