Modern smartphones such as Xiaomi Redmi 9, have become an integral part of our digital lives, providing access to information, entertainment, and work at any time. However, despite the shell's well-thought-out interface MIUIUsers often experience difficulties setting up their wireless connection for the first time or troubleshooting unexpected outages. Proper network configuration is essential for stable device operation, impacting page loading speeds and video call quality.
Owners Redmi 9 value their gadget for its battery life and bright screen, but without a high-quality connection to router These advantages become meaningless. In this article, we'll not only detail the standard procedure but also delve into hidden settings that can help optimize your connection. You'll learn how to fix common errors and ensure maximum data transfer speed.
Setting up the Internet on Xiaomi It may seem like a trivial task, but knowing the nuances can help avoid many problems in the future. We'll cover the process from basic module activation to manual registration. IP addressesThis approach ensures that your phone will function correctly even in difficult signal conditions.
Basic wireless network connection
The first step to accessing the global network is to activate the corresponding module in the system. For owners Redmi 9 Pull down the notification shade at the top of the screen. Find the icon that resembles a fan or antenna and tap it until it lights up blue. This initiates a scan for available access points within range.
After activating the module, go to the main settings menu. This is usually a gear icon, which may simply be called "Settings." In the list that opens, look for the section Wi-Fi, which is often located at the top of the menu or in the "Wireless Networks" group. Clicking it will display a list of detected networks, from which you'll need to select your router's name.
If the network is password protected (which is the security standard WPA2/WPA3), the system will prompt you to enter the access key. Enter the character combination indicated on the router sticker or the one you previously set. Please pay attention to the case, as the system distinguishes between uppercase and lowercase characters. After entering, click "Connect" and wait until the "Connected" status appears.
⚠️ Important: When entering a password, make sure the screen's autocorrect or predictive text feature is not enabled, as this could unnoticeably change characters. It's best to disable autocorrect when entering a complex security key.
Advanced settings and static IP
Sometimes automatically obtaining an address isn't enough to ensure stable operation of apps or games. In these cases, manually configuring network settings is necessary. To do this, in the network selection menu, click the arrow or the name of your current network to open the additional menu and select "Configure" or "Change Network." In the window that opens, find "IP Settings."
By default, there is a value DHCP, which means the router assigns addresses automatically. Switch this setting to "Static." You'll see fields for manual data entry. Typically, you'll need to enter the IP address, gateway (router), and DNS servers. This information is often the same as the router's address, for example, 192.168.1.x.
Using a static address is especially useful if you are configuring local network Or you want to avoid potential addressing conflicts. However, be careful: an incorrectly entered gateway will completely disable your phone's internet access. After making changes, be sure to click "Save" to apply the new settings.
☑️ Check before changing IP
Diagnosing connection problems
The situation when Redmi 9 The problem of seeing the network but not connecting is quite common. First, you need to make sure the problem is with your phone, not your ISP or router. Try connecting another device to the same network. If the internet works elsewhere, you need to look for the cause in your smartphone settings.
A common cause of crashes is the accumulation of errors in network protocols. In this case, resetting the network settings helps. Go to the menu Settings → Connection and sharing → Reset Wi-Fi, mobile networks, and BluetoothThis operation will delete all saved passwords and reset the network modules to factory settings, which often solves the problem of a frozen connection.
It's also worth paying attention to the date and time. If the system time is incorrect, security certificates won't be able to verify, and the connection will be blocked. Make sure "Use network time" is checked in the "Date and Time" section. This will ensure synchronization with the server and proper operation. SSL protocols.
| Problem | Possible cause | Solution |
|---|---|---|
| "Saved" but no internet | Incorrect password or encryption type | Forget the network and re-enter the password |
| Constant disconnections | Channel congestion or weak signal | Change your router channel or switch to 5 GHz |
| Slow speed | Background downloads or the old standard | Check background apps and 802.11 mode |
| Doesn't see the 5 GHz network | The module only operates at 2.4 GHz. | Use 2.4 GHz frequency (standard for Redmi 9) |
Why might Redmi 9 not see the 5GHz network?
This smartphone model is equipped with an 802.11 a/b/g/n/ac Wi-Fi module, but in some regions and models, 5 GHz band support may be limited by software or hardware. If the router broadcasts a 5 GHz network with a channel above 100 MHz or a channel width of 80/160 MHz, budget modules may ignore them. Try forcing the router to use channels 36-48 in its settings or switching to the 2.4 GHz band for maximum compatibility.
DNS optimization for faster internet speed
The speed of page loading and application response often depends not only on the bandwidth but also on the speed of DNS servers. Providers provide their own servers by default, which can be slow. Android and the shell MIUI It is possible to specify alternative addresses, for example, from Google or Cloudflare.
To change your DNS, go to your active Wi-Fi connection settings, click "IP Settings," and select "Static." Enter your preferred addresses in the "DNS 1" and "DNS 2" fields. For example, for Google, this is 8.8.8.8 And 8.8.4.4, and for Cloudflare - 1.1.1.1This can significantly reduce response times when loading websites.
In addition, in modern versions Android The "Private DNS" feature is available. It is located in the general connection settings. Enabling this option and specifying the address (for example, dns.google) encrypts your DNS requests, increasing privacy and protecting against address spoofing by your ISP. This is especially important when using public networks.
⚠️ Note: Using third-party DNS servers may affect the operation of some local ISP services or parental controls. If certain websites or apps stop opening after changing your DNS, reset your settings to "Automatic."
Works with 2.4 GHz and 5 GHz bands
Modern routers often broadcast two networks: the good old 2.4 GHz and the faster 5 GHz. Smartphone Redmi 9 It supports both bands, but there are some caveats. The 2.4 GHz band has better wall penetration, but it's heavily congested with neighboring routers and Bluetooth devices, reducing speed.
The 5 GHz band provides high speeds and minimal latency, which is critical for online gaming and 4K video playback. However, it's less effective at penetrating obstacles. If your router is in the same room as your phone, it's definitely worth connecting to 5 GHz. If your device is farther away or behind several walls, 2.4 GHz will be more stable.
It's important to note that some routers combine both bands under one name (Smart Connect technology). In this case, the phone itself decides which one to connect to. If Redmi 9 If it constantly hangs on a slow frequency, it makes sense to separate the network names (SSID) in the router settings, adding "_5G", and force the phone to connect to a fast network.
Reset and restore network settings
If none of these methods help and connection issues are chronic, there's a radical but effective solution: a complete network settings reset. This won't affect your personal files, photos, or contacts, but it will delete all saved Wi-Fi passwords, Bluetooth pairings, and mobile network settings.
You can perform a reset through the menu Settings → Connection and sharing → Reset Wi-Fi, mobile networks, and BluetoothConfirm the action by entering your screen unlock password. After rebooting, your phone will be as good as new in terms of connectivity, and you'll need to re-enter your home internet password.
This procedure often solves problems associated with firmware software glitches. MIUI, which may have occurred after a system update. If this doesn't help, the problem may lie in the antenna module hardware, in which case diagnostics at a service center will be required.
⚠️ Note: The menu interface may vary slightly depending on the MIUI version (12, 12.5, 13, 14). If you can't find the reset option in the specified path, use the Settings search and search for "Reset."
Frequently Asked Questions (FAQ)
Why does Redmi 9 say "Saved" but there is no internet?
Most often, this means the password is entered correctly, but the router isn't providing an IP address or doesn't have access to the global network. Try rebooting the router. If that doesn't help, forget the network on your phone and reconnect. Also, check if there's a MAC address restriction in the router settings.
How do I know what frequency my Wi-Fi is on?
Look at the network name in the list of available networks. If you renamed the networks on your router yourself, adding "5G" or "2.4", then it's easy. If the names are the same, go to Settings → Wi-Fi → (arrow next to the network name)The "Frequency" line will indicate 2.4 GHz or 5 GHz.
Can a case interfere with the Wi-Fi signal on the Redmi 9?
Yes, if the case has a metal base or inserts. Metal shields the signal, significantly reducing reception. Try removing the case and checking the signal strength. Thick mirrors or aquariums between the router and the phone can also shield the signal.
What should I do if my phone doesn't see any Wi-Fi networks?
If the network list is empty or the power button is grayed out and inactive, there may be a driver issue. Try toggling Airplane Mode on and off. If that doesn't help, reset your network settings. In the worst-case scenario, your device may need to be reflashed or repaired.
Is it safe to use public Wi-Fi on Redmi 9?
Without additional security measures, no. Data can be intercepted in public places. Always use a VPN when connecting to open networks in cafes or on public transport. Also, make sure your network settings are set to "Public" rather than "Trusted" to hide your phone from other devices.
