How to connect Redmi 8 to a 5GHz Wi-Fi network: settings and troubleshooting

Modern smartphones such as Redmi 8, are equipped with powerful wireless modules capable of operating in two frequency bands. However, many users encounter a situation where the device doesn't detect the 5 GHz network or automatically connects to the slower 2.4 GHz band. This may be due to software restrictions in the region, router settings, or firmware issues. MIUI.

In this article, we'll cover all possible ways to activate a high-speed connection. You'll learn how to check hardware support, change the region in the system settings, and properly configure your router for stable operation. Correct configuration will allow you to significantly increase download speed and reduce ping in games.

Before moving on to complex steps, you need to make sure your equipment even supports this frequency range. Not all routers and smartphones, even those released at the same time, have the same antenna set. Redmi 8 supports the 802.11ac standard, which guarantees compatibility with 5GHz networks if configured correctly.

Checking hardware support and specifications

The first step should always be a technical diagnosis. Smartphone Xiaomi Redmi 8 based on the processor Snapdragon 439, which theoretically supports dual-band Wi-Fi. However, in some revisions or for certain markets, the manufacturer may have software-limited the functionality of the communication module.

To determine if your phone can see the network, get as close to the router as possible. If the list of available networks only shows 2.4 GHz, even though nearby devices can see 5 GHz, the problem lies in the smartphone's settings. This is often related to the country selection during initial activation.

• 📱 Check the model in the section Settings → About phoneto make sure you have the Redmi 8 and not a cut-down version.
• 📡 Make sure that your router is actually broadcasting a 5 GHz network and that it is not hidden (Hidden SSID mode is not enabled).
• 🔋 Charge the battery to at least 30%, as searching for networks and switching modules can consume more power.

It's important to understand that the 5 GHz band has less penetration power. If you're behind two concrete walls from your router, your phone may simply not detect this network, even if it's active. In such cases, physical location plays a decisive role.

Changing the region in MIUI settings

One of the most common reasons for the lack of 5 GHz networks on devices Xiaomi There's a software region restriction. Some countries have legal restrictions on the use of certain channels or frequencies in the 5 GHz band. If you selected a region with strict restrictions when you first turned on the phone, it may not scan for these frequencies.

The solution lies in changing the system's geolocation. You don't need to change the language or time format; just the region setting. This is safe and doesn't delete any personal data or reset your settings.

Follow these steps:

1. Open the menu Settings on the main screen.
2. Go to the section Additionally (or Advanced settings).
3. Select an item Region.
4. In the search or list, find and select Indonesia, India or Singapore.

⚠️ Please note: After changing your region, the pre-installed apps and news feed may change. This is normal, as the content is adapted to the selected country.

After changing the region, your phone may reboot its network module. Wait about 30 seconds and check the list of available Wi-Fi networks. In most cases, the 5 GHz network appears immediately. If this doesn't happen, try completely turning Wi-Fi off and on again in the notification shade.

Configuring your router for compatibility

Even if the phone is ready to receive a signal, the router must broadcast it correctly. The problem often lies in the broadcast channel selection. Some channels in the 5 GHz band may be prohibited in the phone's current region, even if the router itself uses them.

Log into your router's web interface (usually at 192.168.0.1 or 192.168.1.1). Find the wireless network settings section. Wireless or Wi-Fi Settings. Make sure the operating mode (Mode) is set to 802.11 a/n/ac mixed or simply 802.11ac.

A critical parameter is the channel width and its number:

• 📡 Channel width: set 20/40/80 MHz or forced 80 MHz for maximum speed.
• 🔢 Channel number: Select channels 36, 40, 44, or 48. These are the most universal and supported by most devices.
• 🚫 Avoid DFS (Dynamic Frequency Selection) channels if your phone has trouble seeing them, although the Redmi 8 should be able to handle them.

After applying the settings, the router may reboot. This is normal behavior. Make sure the network name (SSID) for the 5 GHz band is different from the 2.4 GHz network name so you can clearly identify which one you're connecting to.

Resetting your smartphone's network settings

If changing the region and configuring the router didn't help, it's possible that network caching errors or configuration file conflicts have accumulated in the system. In this case, a full reset of network settings will help. This will return Wi-Fi, Bluetooth, and mobile data settings to factory defaults.

Important: This step will not delete your photos, contacts, or apps. It will only delete saved Wi-Fi passwords and Bluetooth device pairings. Therefore, it's best to write down or memorize passwords for important networks in advance.

Steps to follow for Redmi 8:

1. Go to Settings.
2. Select a section Connection and sharing (or Advanced settings).
3. Find the item Reset Wi-Fi, Mobile Networks, and Bluetooth.
4. Click the button Reset settings at the bottom of the screen.
5. Confirm the action by entering the screen unlock password.

After rebooting, your phone will be "clean" in terms of network connections. Try searching for the 5 GHz network again. This method often resolves issues when the phone gets stuck on older communication protocols.

⚠️ Important: Make sure you reset your network settings and not a full factory reset (Hard Reset), which will delete all data from your device.

Using the engineering menu and third-party utilities

For advanced users who have found standard methods ineffective, there is the option to access the hidden settings of the radio module. In the shell MIUI There is a special engineering menu that allows you to test antennas and force changes in operating modes.

To access the testing menu, open the application Telephone (dialer) and dial the code ##6484##. A menu will open. CIT (Customer Information Test). Find the test WiFiThere you can run a signal test and see technical information about available frequencies.
