Changing your mobile's WiFi band from 5 GHz to 2.4 GHz is entirely possible.Although many modern devices automatically select the best band, sometimes it's necessary to choose manually, especially if you need to connect smart devices, cleaning robots, cameras, or other devices that only support 2.4 GHz, or if you're experiencing connection and stability issues. We'll explain everything you need to know to choose the right band and how to do it step by step.
What do the 2.4 GHz and 5 GHz WiFi bands mean?
When talking about WiFi, it is important to understand that there are several frequency bands that use different technologies. The 2.4 GHz band has been around since the first WiFi routers and is compatible with most current and older devices. For its part, The 5 GHz band is newer and offers higher speeds. and is recommended for modern devices such as laptops, Smart TVs and video game consoles.
The 2.4 GHz band has greater range and better penetration through walls, making it suitable for covering large areas or connecting devices far from the router. However, it's also more susceptible to interference, as it shares the frequency with other household devices such as microwaves, cordless phones, or even Bluetooth.
In contrast, The 5 GHz band offers much faster transmission speeds and is less prone to congestion. However, its range is more limited, and the signal weakens more easily when faced with obstacles or thick walls.
To understand this better, imagine two roads: a very wide one (5 GHz) where many cars can travel very quickly up to a certain point, and a narrower one (2.4 GHz), slower but which reaches much further, even to remote places. Older devices will only be able to use the 2.4 GHz band, while newer ones can choose any.
Advantages and disadvantages of each band:
- 2.4 GHz: Greater coverage, ideal for distant devices or thick walls, but lower speed and higher risk of interference.
- 5 GHz: Higher connection speed, less interference, and higher capacity for many devices, but shorter range.
Why is it useful to change the Wi-Fi band on your mobile?
The need to switch from 5 GHz to 2.4 GHz often arises when you have problems connecting smart devices or if you experience cuts or slowness on your mobile.Many Internet of Things (IoT) devices, such as surveillance cameras, smart plugs, or robot vacuum cleaners, only operate on 2.4 GHz. In addition, if the router is far away or your house has several walls, the 5 GHz signal may not reach with sufficient strength, making it advisable to use the 2.4 GHz signal.
It could also be that the 5 GHz band is too congested, either due to the use of multiple devices or your neighbors' networks. In these cases, switching to 2.4 GHz may improve connection stability.
How to know which Wi-Fi band your mobile phone is connected to
Before changing anything, it's helpful to check which band your phone is connected to. To do this, follow these steps:
- Access the WiFi settings of your mobile.
- Select the network you are connected to and check if the SSID name shows something like "5G", 5GHz o "More"The 2.4 GHz network usually displays only the base name, while the 5 GHz network includes some of these indications.
- On some phones, you can see the exact frequency in advanced network details.
How to change the Wi-Fi band on your Android phone: step by step
Changing the band depends on both your mobile phone and how your router is configured.There are two main methods: from your mobile phone by selecting another network, or from your router's configuration panel. Here's how to do both:
- Go to the menu of adjustments from your Android device.
- Access the section WiFi o Network and Internet.
- Tap on the active Wi-Fi network. On advanced models, you can find frequency settings o available networks.
- If your router has different band names (for example, "RedCasa" for 2.4 GHz and "RedCasa-5G" for 5 GHz), select the 2.4 GHz band and connect with your usual password.
- On some mobile phones, in advanced settings Within the WiFi network, you will find the option WiFi frequency band. Choose 2.4 GHz and save the changes.
On other Android models, the selection may be under "Available Networks" within Wi-Fi. If only one network appears and there's no option to choose a band, your router is likely using a feature known as Smart WiFi or Band SteeringIn this case, the router automatically decides which band to connect each device to based on its capacity, signal, and saturation.
In this case, you have several options:
- Temporarily disable the 5 GHz band from the router's configuration panelThis will force all devices to connect via 2.4 GHz.
- Call your operator to ask for help separating the bands or deactivating smart mode.
- Create a secondary SSID Only for 2.4 GHz via the router's advanced settings. This way, you can connect your phone and gadgets to that specific SSID.
Configure the WiFi band from the router
Most modern routers allow you to easily change these options:
- Connect to the router from a browser by entering the Router IP (usually 192.168.1.1) in the address bar.
- Log in with the administrator username and password (you can find them on a label under the router).
- Go to WiFi configuration o Advanced settings.
- Disable smart WiFi mode or band steering.
- Create two separate networks, one for 2.4 GHz and one for 5 GHz, assigning different names (SSIDs).
- Save the changes and, from your mobile, manually select the 2.4 GHz network.
Some routers also offer the option of secondary SSIDs.This allows for exclusive networks for each band, thus avoiding compatibility issues with smart devices.
The 2.4 GHz band is useful but is also more congested.. For the best experience:
- Place the router in a central, elevated location in your home.
- Avoid placing the router near microwaves, cordless phones, or Bluetooth devices, which can cause interference.
- Change the transmission channel in your router settings if you notice many networks nearby and your signal is weak.
- Do not share the network name (SSID) of 2.4 GHz and 5 GHz to easily differentiate them.
