Does Dual Band Router Switch Automatically? ( Comprehensive Guide 2023)

A Dual-band router is a popular choice for many households due to its ability to support multiple devices and offer faster internet speeds.

One common question that arises Does Dual Band Router Switch Automatically between the 2.4GHz and 5GHz frequencies?

No, most dual-band routers do not switch automatically between the two frequencies. But some of the routers switch automatically such as Google Nest.

In this article, we will explore the benefits of a dual-band router, how it works, and what to consider when purchasing one for your home or office.


A Dual-band router is a router that uses two different radio frequency bands (2.4 GHz and 5 GHz) to communicate with devices on your home network.

The significant advantage of having a dual-band router is that it can provide better range and more consistent speeds compared to a single-band router.

It can support more devices simultaneously without running into bandwidth issues, which is great if you have a lot of devices in your home that need to connect to Wi-Fi.

A dual-band router also supports older devices that only support the 2.4GHz band, allowing them to connect to your network without any problems.

Therefore, investing in a dual-band router is an excellent decision to ensure that all of your devices can connect to your home network effortlessly.

Does Dual Band Router Switch Automatically?

No, A dual-band router does not automatically switch between the fastest and slowest bands, nor does it auto-switch between 2.4 GHz and 5 GHz networks. Instead, the user needs to connect to both networks manually.

By doing so, they can prevent the router from automatically switching between two different bands when connected to the same network, which could potentially disrupt connectivity.

Seamless switching between two different wireless bands is difficult or impossible to achieve, and there are many online activities that require a constant and consistent connection.

Therefore, having the router continually break the connection to switch to whichever band it considers “fastest” at any given moment would not be feasible.


Most dual-band devices that support both 2.4 GHz and 5 GHz bands, or even tri-band devices that support 2.4 GHz, 5 GHz, and 6 GHz, will try to automatically select the best band based on various factors like signal strength, distance from the Wi-Fi point, client compatibility, and security.

It seems that it can be quite challenging to work consistently on the internet if the router is constantly switching between the two bands, which may cause interruptions during the use of the faster band.

To avoid this, users can switch their particular access point between the two bands, rather than letting the router automatically switch back and forth.

How To Switch Network Between 2.4 And 5 GHz?

If you own a dual-band router, you may be wondering about switching between the 2.4 GHz and 5 GHz bands. It is a straightforward process.

To switch between 2.4 GHz and 5 GHz networks on your device, follow these steps:

Step 1: Open the settings on your device.

Step 2: Look for the Wi-Fi option and click on it.

Step 3: Find the name of your Wi-Fi network and click on it to access the network settings.

Step 4: If your device supports both 2.4 GHz and 5 GHz networks, you should see two separate network names for each frequency band.

Step 5: Select the network you want to connect to, either the 2.4 GHz or 5 GHz network.

If Your Router Has an Automatic Switching Feature Then Follow This:

Step 6: If you want your device to automatically switch between the two networks depending on signal strength, make sure the “Smart Network Switch” option is turned on.

Note that some devices may have slightly different steps, but generally, these are the steps you’ll need to follow to switch between 2.4 GHz and 5 GHz networks on your device.

Comparison between 2.4GHz and 5GHz Wi-Fi bands

Here are some scenarios where it might be better to connect to one band versus the other:


5 GHz Wi-Fi has a shorter wavelength and more speed, allowing it to handle more users.

In contrast, 2.4 GHz Wi-Fi has a longer wavelength, limiting its bandwidth and the number of users it can support.

Walls and Obstacles:

If you have a large house or office with many walls and obstacles, connecting to the 2.4 GHz band may be better as it can pass through solid objects more easily and provide more reliable connections over longer distances.

Densely populated area:

If you live in an apartment building or densely populated area where there are many Wi-Fi networks near, connecting to the 5 GHz band may be better as it can provide higher potential speeds and handle more users at once.

Comparing 2.4GHz and 5GHz Wi-Fi bands

Device Bandwidth:

If you have a device that requires a lot of bandwidth, such as streaming video or online gaming, connecting to the 5 GHz band may be better as it can deliver higher potential speeds and handle more data at once.

Older Device:

If you have an older device that only supports 2.4 GHz Wi-Fi, then obviously you will need to connect to the 2.4 GHz band. 

Overall, the best band to connect to will depend on your specific situation. It may be worth experimenting with both bands to see which one works better for you.

How To Setup A Dual-Band Router?

Setting up a dual-band router is a straightforward process. Here are the basic steps to set up a dual-band router:

Step 1: Unpack the router and connect it to your modem using an Ethernet cable.

Step 2: Connect your computer or laptop to the router using an Ethernet cable or via Wi-Fi.

Step 3: Open your web browser and enter the router’s IP address into the address bar. This is usually found in the router’s user manual.

Step 4: Enter the default login credentials for the router. This is usually also found in the user manual. Once logged in, you’ll be prompted to change the default login credentials for security reasons.

Step 5: Configure the settings for both the 2.4 GHz and 5 GHz networks. Make sure to set different network names and passwords for each network.

Step 6: Set up the security settings for each network, such as WPA2/WPA3 encryption and a double firewall.

What Is The Best Time To Use The 2.4 GHz Band?

Here are some potential situations when we use the 2.4 GHz Wi-Fi band:

  • If you have a small number of users connecting to your router and your internet speed is less than 100 Mbps, you can manage just fine on only the 2.4 GHz band.

  • If you are using Wi-Fi far away from your router, the 2.4 GHz band works better over longer distances.

  • If you are not experiencing any congestion issues or if bandwidth demands in your home are generally low, there is no need to switch to 5 GHz.

  • If you have safety concerns about 5 GHz Wi-Fi technology, use single-band routers that only use 2.4 GHz frequency, or disable the 5 GHz band and use wired connections only.

  • For gaming, 2.4 GHz is usually preferable, except for crowded home networks where some devices can be moved to the 5 GHz band to minimize congestion. However, it is always recommended to use wired connections for gaming.
