Modern smartphones such as Xiaomi Redmi 8, are powerful multimedia centers that require stable internet access. Without a wireless network connection, the device's functionality is significantly limited: it's impossible to download app updates, sync contacts, or use navigation. The setup process Wi-Fi connections This device is standardized, but has its own peculiarities in the MIUI shell, which are important to take into account for quick and successful configuration.
In this guide, we'll walk you through every connection step, from simple password entry to manual IP address configuration for advanced users. You'll learn how to fix common errors, why your phone might not detect the network, and what hidden features are available in the settings menu. Proper configuration will ensure maximum data transfer speed and signal stability anywhere in your home or office.
Basic wireless setup
The first step to accessing the internet is activating the wireless module. In the Android operating system, which Redmi 8There are two main ways to do this: through the quick access panel or through the main settings menu. Both methods are equally effective, but the latter provides access to advanced functionality.
To quickly turn it on, pull down the notification shade by swiping down from the top. Look for the fan-shaped icon or the letter "W"—that's the indicator. Wi-FiIf it's blue, the module is active. If the icon is gray or missing, tap it to activate the search for available networks. Once activated, the phone will automatically begin scanning the airwaves.
More in-depth customization is available through the path Settings → Wi-FiHere you'll see a toggle at the top of the screen. Move the slider to the "On" position. The system will immediately display a list of available access points for connection. Networks requiring authorization will be marked with a lock icon, indicating data encryption.
- 📶 Open networks: Accessible hotspots without a password, connection to which occurs automatically, but they are less secure.
- 🔒 Secure networks: require entering a security key (password) to establish a connection.
- 🏠 Hidden networks: are not displayed in the general list and require manual entry of the name (SSID) and security parameters.
⚠️ Warning: When connecting to open public networks in shopping malls or cafes, your data may be intercepted. It is not recommended to conduct banking transactions or enter passwords for important services without using a VPN.
Select the desired network from the list. If it is password-protected, the system will prompt you to enter it. After entering the security key correctly, Redmi 8 will attempt to obtain an IP address from the router. A successful connection will be confirmed by the word "Connected" appearing under the network name and the Wi-Fi icon appearing in the screen's status bar.
Troubleshooting network connectivity and visibility issues
Sometimes users encounter a situation where The phone doesn't see Wi-Fi or it constantly displays "Connection Error." This could be caused by a software glitch in the module, outdated DHCP settings, or a frequency conflict. First, try restarting your smartphone—this resolves most temporary software errors.
If rebooting doesn't help, check your date and time settings. A mismatch between your system time and security certificates may be blocking the connection. Go to Settings → Additional settings → Date and time and make sure "Use network time" is checked. Also, try "Forgetting" the problematic network: click the network name in the list and select "Remove," then re-enter the password.
In some cases, the router is operating on a channel that is poorly received by the mobile device, or it uses the 802.11ax standard, which older firmware versions may not handle correctly. Try changing the broadcast channel in the router settings to 1, 6, or 11. It's also worth checking if the router has a MAC address filter enabled, which is blocking new devices.
- 🔄 Reset network settings: A radical method that returns all network parameters to factory defaults.
- 📡 Change range: Switching between 2.4GHz and 5GHz frequencies can improve signal stability.
- 🛡️ Antivirus: Third-party security applications sometimes block the connection because they consider the network suspicious.
⚠️ Note: Resetting network settings will delete all saved Wi-Fi passwords and Bluetooth device settings. You will need to re-enter passwords for all known networks.
Manual configuration of IP and DNS parameters
For advanced users or on corporate networks, manual IP address configuration may be required. By default Redmi 8 Uses the DHCP protocol, which automatically assigns addresses. However, if the router doesn't assign addresses or a static IP address is required for port forwarding, the settings must be changed manually.
In the Wi-Fi menu, click on your network name (or the arrow to the right of it) to open additional settings. Find "IP Settings" and change the value from "DHCP" to "Static." Numeric fields will open. It's important not to make any mistakes here, as an incorrect gateway will completely disable internet access.
Typically, a gateway (router) has an address like 192.168.0.1 or 192.168.1.1. Your phone should have an address in the same subnet, but with a different last digit. For example, if the gateway is 192.168.1.1, then your phone could be assigned 192.168.1.55. The subnet mask is usually the standard 255.255.255.0.
Why change DNS?
Changing your DNS servers to public ones (for example, Google's 8.8.8.8 or Cloudflare's 1.1.1.1) can speed up website loading and bypass ISP blocking if your standard DNS is slow.
DNS deserves special attention. You can manually enter DNS server addresses. This is useful if your ISP blocks access to resources or if the default servers are slow. Enter the address in the "DNS 1" field and, if necessary, a backup in "DNS 2."
- 🌐 Gateway: the address of your router through which you access the external network.
- 🏷️ Subnet mask: defines the size of the local network, usually 255.255.255.0.
- 🔢 Static IP: a permanent address that does not change after reconnecting the device.
Using proxy servers on Redmi 8
On corporate networks or for specific services, you may need to configure a proxy server. Unlike on computers, on Android, proxy settings are applied individually for each Wi-Fi network. This means you won't have to change global settings when switching from the office to home.
To configure a proxy, go to the detailed settings of the connected network. Find the "Proxy" section and select "Manual." Fields for entering the hostname (server address) and port will appear. If the proxy requires authorization, fields for login and password will also be available.
There's also an "Automatic Proxy Configuration" option, which allows you to specify the URL of a configuration script (PAC file). This is often used in large organizations for centralized access management. After entering the information, be sure to click "Save," otherwise the changes will not take effect.
Comparison of the 2.4 GHz and 5 GHz frequency bands
Modern routers often broadcast two networks: one at 2.4 GHz and the other at 5 GHz. Xiaomi Redmi 8 Supports both standards, but users must understand the differences to make the optimal choice. The 2.4 GHz frequency provides greater coverage and penetrates walls better, but is slower and susceptible to interference from microwaves and Bluetooth.
The 5 GHz band offers significantly higher data transfer rates and less interference, as it's less congested with neighboring routers. However, the signal on this frequency has poorer penetration through obstacles and a shorter range. For 4K video streaming or online gaming, 5 GHz is preferable if you're close to the router.
| Characteristic | 2.4 GHz band | 5 GHz band |
|---|---|---|
| Transfer speed | Up to 450 Mbps | Up to 1300 Mbps and higher |
| Range | Large, penetrates walls well | Smaller, more sensitive to obstacles |
| Workload | High (a lot of interference) | Low (pure ether) |
| Best use | Surfing, instant messaging, smart home | 4K video, games, file downloads |
If your router combines both bands into a single network (the Smart Connect feature), the phone will automatically decide which one to connect to. However, sometimes the algorithm malfunctions, and the phone gets stuck on the slow 2.4 GHz band, even though the fast 5 GHz band is nearby. In this case, it's best to separate the networks in the router settings by giving them different names, for example, "Home_2G" and "Home_5G."
Energy optimization and security
Constantly scanning for networks and background syncing can drain battery power. MIUI There's a "Wi-Fi Assistant" feature that automatically turns off the module when you leave the coverage area of known networks, or switches to mobile Internet if the Wi-Fi signal becomes too weak.
For increased security, we recommend disabling WPS if you're not using it, as this authentication method has known vulnerabilities. Also, monitor app permissions: some programs may request access to geolocation via Wi-Fi, which isn't always necessary for their operation.
Keeping your phone's firmware up to date is crucial. Updates security systems Xiaomi frequently patches vulnerabilities that could allow attackers to access data transmitted over the wireless network. You can check for updates in the menu. Settings → About phone → System update.
☑️ Wi-Fi Security Check
⚠️ Note: The MIUI interface may vary slightly depending on your Android version and regional firmware. The layout of menu items may change after major system updates.
