- Identifying the Wi-Fi band is key to optimizing your connection and avoiding compatibility issues.
- Routers usually provide the frequency in the Wi-Fi name or allow you to check it in the settings.
- The method for determining the connected band varies depending on the operating system and type of device.
Have you ever wondered if you're connected to a 2.4 GHz or 5 GHz Wi-Fi network and don't know how to find out? More and more homes and offices have dual-band routers that broadcast on both frequencies, but it's not always easy to identify which band you're connected to. Knowing this information can make a difference in speed, range, and compatibility of your devices.
In this article, you'll find a clear and detailed explanation of how to identify your network's Wi-Fi band—whether you're using a mobile phone, a computer, or want to dig deeper into your router's configuration—as well as learn the key differences between the two frequencies and the best situations to choose one or the other. Here's everything you need to optimize your home connection and avoid headaches when your devices aren't connecting as expected.
What does it mean for a Wi-Fi network to be 2.4 GHz or 5 GHz?
The Wi-Fi frequency indicates the band on which your wireless signal is transmitted. router. The two most common bands are 2.4 GHz and 5 GHz. Broadly speaking, The 2.4 GHz is the traditional one, it has been on the market longer, offers greater range but lower speed, and is often more affected by interference (lots of competition with other wireless devices). 5 GHz is more modern, allows for faster and more stable connections, but its range is more limited and it suffers more from walls and obstacles.
Nowadays, many routers broadcast on both bands at the same time, which is called dual-band Wi-Fi. In these cases, devices can automatically connect to the band they consider most appropriate, or you can manually choose between the two if the router offers them separately.
Why is it important to know which Wi-Fi band you are connected to?
The frequency at which you connect directly affects your internet usage experience.If you need greater coverage for devices far from your router, you'll want 2.4 GHz. If you're looking for maximum speed and less interference (for example, to watch 4K content or play online games), 5 GHz is your ally. Plus, many smart devices, such as light bulbs, robots Vacuum cleaners or Wi-Fi cameras specifically require the 2.4 GHz band because they are not compatible with 5 GHz..
How to identify the Wi-Fi band from the network name (SSID)
The easiest and most direct way to find out if a network is 2.4 GHz or 5 GHz is to look at the name that appears in the list of available networks. Many routers, especially those installed by your internet provider, They add a suffix like “_2.4G” or “_5G” to the Wi-Fi name. to differentiate both bands. For example, you might see something like “MiCasaWifi_5G” and “MiCasaWifi” o “Movistar_XXXX” for 2.4 GHz and “Movistar_Plus_XXXX” for 5 GHz.
If you see two similar names, one is probably the 2.4 GHz network and the other is the 5 GHz network.You can choose which one to connect to based on your needs. If you only see one, it's possible that:
- The router is configured to broadcast only on one band.
- Both bands are united under the same name (dual wifi with SSID unique).
On networks where both bands have the same name (unique SSID), the device will automatically choose which one to connect to. This is common on newer routers and can make it difficult to know which band you're actually connected to.
What happens if the network has the same name for both bands?
Some newer routers combine the two bands under a single network name. In this case, you do not manually choose which one to connect to, but rather The router, through a function called 'band steering', intelligently decides which frequency to assign to each device based on its location, compatibility and signal conditions.
This helps make the experience more seamless, but can be frustrating if you need a device to connect to a specific band (for example, smart devices that only work on 2.4 GHz). In these cases, many routers allow you to disable this feature in the settings and display both bands with separate names.
How to know the Wi-Fi frequency on Android devices
En Android, checking which band you are connected to is easy and the information usually appears directly in the settings. Depending on the make and model, follow these steps:
- Opens Settings, enter the section Wi-Fi.
- Click on the name of the network you are connected to.
- In the detailed information (sometimes under the heading “Frequency”) it will tell you whether it is 2.4 GHz, 5 GHz or even “Dual”.
On many Xiaomi, Samsung, and other phones, you'll also see this information next to the network name or within the connection details. If you only see 2.4 GHz and nothing about 5 GHz is specified, you're likely connected to the 2.4 GHz band.
Check Wi-Fi Band on iPhone or iPad
En iOS, the information about the band you are connected to does not appear as clearly as on Android. In recent versions of the system, The Wi-Fi settings app doesn't show whether it's 2.4 or 5 GHz. However, you can deduce it by following these Tricks:
- If you see two networks with similar names and one includes “5G”, the other will be 2.4 GHz and you can choose manually.
- If there is only one visible network, it is probably 2.4 GHz (the most compatible).
- You can also check by going into your router settings or using Wi-Fi analysis apps (if available on the App Store).
Apple prioritizes ease of use and leaves less technical data visible, but you can rest assured that the iPhone Most modern phones (starting with the iPhone X) support 5GHz and, if your router allows it, will choose the best band available.
Identify the Wi-Fi frequency on Mac computers (macOS)
In the Mac There is a very quick and effective trick to know which Wi-Fi band you are connected to:
- hold down the key Option (⌥) (o Alt on keyboards Windows) and click the Wi-Fi icon in the top bar.
- A window with technical information will appear, where you will see the “Channel” section: If it says “2.4 GHz” or “5 GHz” in parentheses after the channel, you will know what frequency you are connected to.
- Remember that if both bands have the same name (dual band), your Mac may automatically switch between them depending on the signal quality and distance from your router. The further you are from your router, the more likely you are to be using the 2.4 GHz band.
How to know the Wi-Fi band on Windows computers
In Windows 10 and higher, you can easily see your Wi-Fi network frequency:
- Click the Wi-Fi network icon in the taskbar (bottom right of the screen).
- Right click on the network you are connected to and select Properties (or go to “Network & Internet settings” and then Wi-Fi → Hardware).
- In the properties section, look for the “Network Band” or “Frequency” section, which will show you whether it is 2.4 GHz or 5 GHz.
Check the Wi-Fi band by consulting the label or the router settings.
Another way to tell if your router broadcasts on 2.4 GHz, 5 GHz, or both is to look at the label on the bottom of the device itself. Typically, the names of the generated Wi-Fi networks (SSIDs) and default passwords appear here. If you see two different names, one will probably be 2.4 GHz and the other 5 GHz..
You can also access the router's administration panel from your browser by entering the usual IP (192.168.1.1 or 192.168.0.1) and then the username and password (usually admin/admin or similar if it has not been changed)From here you can view the band settings, activate or deactivate each one, and change the names if you want to better differentiate them.
Sometimes, manuals or help videos (many carriers like Movistar offer specific tutorials) also explain how to view this information and modify the settings according to your needs.
Call your internet provider if you have questions.
If after checking the network name, router settings, and your device settings you still don't know if your Wi-Fi is 2.4 GHz or 5 GHz, you can call your carrier.They can check it remotely and tell you if you have both bands active, if your router is dual-band, or if any bands are disabled. This option is especially useful if you can't access advanced settings or prefer not to touch anything technical.
Why do smart devices typically only use the 2.4 GHz band?
Most home automation products and smart appliances (light bulbs, cameras, robot vacuum cleaners, Wi-Fi plugs, etc.) only work on 2.4 GHz.This is because it's the most widely used band and guarantees maximum compatibility worldwide. Additionally, since they need to work in rooms far from the router, Greater 2.4 GHz coverage is critical to avoid disconnections.
If you only have the 5 GHz band enabled or are using a combined SSID that doesn't allow you to manually select the band, you may have trouble pairing these devices. On most routers, you can separate the SSIDs from the settings menu to make connecting these devices easier.
Key differences between 2.4 GHz and 5 GHz Wi-Fi
- Reach: The 2.4 GHz signal reaches farther and penetrates walls and obstacles better. The 5 GHz signal is more sensitive but perfect for open spaces or near the router.
- Speed: 5 GHz offers faster connections (ideal for high-resolution video, online gaming, or large file transfers). 2.4 GHz is slower but sufficient for browsing, social media, and everyday use.
- Interferences: 2.4 GHz is more prone to interference from competition with other devices, while 5 GHz is more stable in congested areas.
- Compatibility: Virtually all devices support 2.4 GHz, but only the latest ones support 5 GHz.
How to change the Wi-Fi frequency between 2.4 GHz and 5 GHz?
If you want to change the band a device connects to, you must configure your router to display both networks with different names.. This way, you can choose manually.Access the router's administration panel from your browser (using the IP address indicated on the device's label) and look for the "Wi-Fi" or "wireless network" section. You can enable or disable each band, change names, and choose channels based on your needs.
Case studies: When to use 2.4 GHz or 5 GHz?
- In large houses or with many walls: The 2.4 GHz band is more recommended because it reaches further.
- For smart devices, cameras, light bulbs and small gadgets: Always choose 2.4 GHz to avoid compatibility issues.
- To streaming in 4K, online gaming or teleworking near the router: The 5 GHz band will give you better speed and fewer dropouts.
- Can I use both bands at the same time? Many routers allow simultaneous use, so each device can choose what works best for its usage and location.
Common mistakes and how to fix them
One of the most common problems is trying to connect devices that only support 2.4 GHz to a combined Wi-Fi network where the router automatically selects the band. This prevents some devices from pairing properly. The solution is to separate the SSIDs and have two different network names for each band. You can also temporarily place the device near the router so it uses its corresponding band.
If you experience frequent disconnections, slow speeds, or incompatibilities, check your network frequency, channel congestion, and consider changing the Wi-Fi channel in your settings to avoid interference with neighboring networks.
