Eero’s mesh Wi-Fi system is a great way to extend your home’s Wi-Fi network to reach every part of the house and even into the yard. Eero has products that act as both Wi-Fi routers and network extenders. I have several devices that require a 2.4 GHz Wi-Fi network, so I did some online research to find out if Eero needs a 2.4 or 5 GHz frequency.

Eero Wi-Fi uses both 2.4 and 5 GHz frequencies in one network. Devices that are connected to an Eero network will automatically switch between the two frequencies as needed for the best possible Internet connection. Users cannot manually change the frequency.

Some products are only compatible with the 2.4 GHz frequency, including many smart home devices. It’s essential to understand how your Eero network uses Wi-Fi frequencies so that you can connect all your devices efficiently.

2.4 GHz vs. 5 GHz Frequencies

All Eero products use both 2.4 GHz and 5 GHz frequencies built into one Wi-Fi network. When you connect a new device to your Eero network, it should automatically connect using the frequency that works best for that device.

But what’s the difference between both frequencies? The 2.4 GHz frequency has a more extended range, while the 5 GHz frequency is faster; this is true for all Wi-Fi routers, including Eero.

Some dual-band routers have separate, selectable networks so that you can manually connect to either a 2.4 or 5 GHz network. However, Eero does not have this option to change the Wi-Fi frequency manually.

Which Wi-Fi Frequency Will My Eero Network Use?

Your Eero router keeps track of all previously connected devices and which frequency each device has used. If a device has used both the 2.4 and 5 GHz frequencies, the router will connect it to the 5 GHz one because generally, higher Internet speeds mean better performance.

  • The faster 5 GHz network is excellent for streaming video, online gaming, and video conferencing. These activities use a lot of bandwidth and work a lot better on faster Internet.
  • For devices that are upstairs, in a garage, or in a back-house, the Eero router will use the 2.4 GHz frequency because of its more extended range. When moving around the house with a mobile device such as a phone, the Eero router will automatically switch the device between the two frequencies as needed to maintain a stable connection. 

Connecting to the 2.4 GHz Frequency

Many smart home devices, such as some light bulbs, motion sensors, and security cams, are only compatible with 2.4 GHz Wi-Fi. To set up these devices, you have to make sure your phone or tablet is connected to your home’s 2.4 GHz Wi-Fi network because that is how these smart home devices will connect.

Some Eero users have reported issues being able to connect their 2.4 GHz-only devices to their Eero network. This issue occurs because the network prefers to use the 5 GHz frequency.

Luckily, there are two ways around this problem:

  1. Walk with your phone at least 50 feet away from any of your Eero routers and extenders. Then, go to the phone’s Wi-Fi settings and “forget” the Eero network. Sign in to the network again from this distance, and your phone should automatically connect to Eero’s 2.4 GHz frequency.
  2. Call Eero Technical Support at 877-659-2347. They can temporarily turn off the 5 GHz frequency of your network while you set up your 2.4 GHz-only devices.

Dual-Band Routers with Separate Networks

Eero and other similar mesh network Wi-Fi systems cannot manually change between the 2.4 and 5 GHz frequencies.

If you want to be able to switch manually between the two frequencies or if you have a lot of 2.4 GHz-only devices, a selectable dual-band router may be a better choice for you than an Eero router.

The great thing about selectable dual-band routers is that you can easily change the frequency at any time by connecting to the other Wi-Fi network option. It will have the same name, but it will have either “2.4G” or “5G” at the end.

A device cannot be connected to both the 2.4 and 5 GHz networks at the same time. One device can only be connected to one Wi-Fi network at a time, so connecting to a 2.4 GHz network will automatically disconnect your device from the 5 GHz network or vice versa.


Eero Wi-Fi routers and extenders have both 2.4 and 5 GHz frequencies that operate simultaneously on the same network. Usually, this means your devices will automatically switch between the frequencies as needed to maintain a reliable Internet connection.

2.4 GHz-only devices may not easily connect to your Eero network because the network favors the 5 GHz frequency. If you want to be able to change the Wi-Fi frequency manually, consider a selectable dual-band router instead so that you can connect each device to the frequency of your choice.

Eero works with two different frequencies, but what about other routers? Check out this article to learn more.
