For owners of this popular budget model, Redmi 9A It is especially important to understand the nuances of the Wi-Fi module, as this device often becomes the first "smart" device for inexperienced users.
The process of configuring a network connection on Android Xiaomi's interface has its own visual features that distinguish it from pure Android. Even in its basic versions, the MIUI interface hides some advanced settings deep within the menu, which can be confusing for those accustomed to a different layout. In this article, we'll cover not only the standard connection process but also solutions for common issues that may arise when trying to connect your device. Redmi 9A with a router.
Connection stability directly impacts app speed, video call quality, and device battery life. An incorrectly selected frequency band or IP address conflict can make using a smartphone a challenge, even if the router itself is working properly. We'll look at how to avoid common mistakes and configure your phone so it automatically and reliably connects to your home or office network without constant intervention.
Preparing the device and initial launch
Before you begin configuring the wireless module, you need to make sure that the device is ready for operation. Redmi 9A The phone comes with a partially charged battery, but it requires sufficient charge for all system processes, including network services, to function properly. If the phone is new, turn it on by holding down the side button and wait for the operating system to complete the initial boot process.
⚠️ Attention: If you see a prompt on the screen to install a SIM card or update the system before the desktop, we recommend performing these steps. An outdated firmware version may contain errors in the wireless module drivers, which are fixed by the developers in security patches.
The MIUI interface may prompt you to select a region and language within the first few minutes of use. Selecting the correct region is important, as it determines the available Wi-Fi frequencies permitted by the laws of a particular country. For example, in some regions, channels 12 and 13 may be unavailable by default if the wrong geographic location is selected.
Make sure you're in an area with a strong signal from your router. Walls, especially load-bearing ones with reinforcement, and household appliances can cause interference. For the initial setup, it's best to get closer to the signal source to eliminate weak reception as a factor when fine-tuning the settings.
Basic procedure for connecting to the network
The standard procedure for connecting to a known network is quite simple, but requires careful entry of the password. For owners Redmi 9A You need to pull down the notification shade by swiping down from the top and find the Wi-Fi icon. An alternative route is through the main settings menu, which provides access to more comprehensive functionality.
- 📡 Press and hold the Wi-Fi icon in the Control Center to quickly access the menu.
- 🔍 In the list of available networks that opens, find the name (SSID) of your router.
- 🔑 Enter your password, paying attention to the letter case and checking your keyboard layout.
- ✅ Click the "Connect" button and wait until the "Connected" status appears.
Particular attention should be paid to entering the password, since the system Android hides entered characters by default. Redmi 9A You can click the eye icon in the password entry field to visually check the entered character combination before submitting. This will save you time and frustration by eliminating repeated entry attempts.
If the network is hidden and doesn't appear in the general list, select "Add network" at the very bottom of the list of available access points. In this case, you'll need to manually enter not only the password but also the exact network name (SSID), and select the encryption type your router uses (usually WPA/WPA2 Personal).
☑️ Check before connection
Setting up advanced Wi-Fi settings
For users looking for a more stable connection or troubleshooting connection issues, advanced settings are available. To access them, Redmi 9ATo do this, click the arrow next to the connected network's name in the Wi-Fi menu or select "Wi-Fi Settings" at the top of the screen. This section contains important options that affect the module's behavior.
One of the key functions is customization MAC addressesBy default, modern smartphones use a randomized MAC address to protect privacy, which means generating a random identifier for each new network. However, some routers with strict MAC address filtering may block such a device.
⚠️ Attention: If you use Parental Controls or MAC address-based access restrictions on your router, you need to change the Privacy setting to use the device's MAC address. Otherwise, the router won't recognize your phone, even with the correct password.
Also in the advanced settings you can find the option to use static IP addressIn standard mode, the phone receives a dynamic IP from the router's DHCP server, which is the norm in 99% of cases. However, if you are setting up a local server, printer, or smart home system that requires a fixed address, you must enable this option and enter the data manually.
Another important parameter is the choice of security protocol. Although Redmi 9A Automatically detects the encryption type, in rare cases when connecting to older routers you may need to manually specify the security type (for example, WEP or WPA) if automatic detection fails.
Works with 2.4 GHz and 5 GHz bands
Modern routers often operate in two frequency ranges: 2.4 GHz and 5 GHz. Smartphone Redmi 9A It supports both standards, but it's important to understand the differences between them for optimal setup. The 2.4 GHz band provides greater coverage and penetrates walls better, but it's heavily congested with neighboring routers and household appliances.
The 5 GHz band offers significantly higher data transfer rates and is less susceptible to interference, but has a shorter range and is less effective at penetrating obstacles. If your router broadcasts two networks with different names (for example, MyWiFi and MyWiFi_5G), the choice depends on your current needs.
| Parameter | 2.4 GHz band | 5 GHz band |
|---|---|---|
| Speed | Up to 150-300 Mbps | Up to 400-800+ Mbps |
| Range | High (up to 50 m indoors) | Medium (up to 20-30 m) |
| Penetration | Good | Bad (walls block the signal) |
| Workload | High (a lot of interference) | Low (pure ether) |
If you're in the same room as your router and plan to watch 4K video or play online games, a 5 GHz network is preferable. However, if you're moving around the apartment or are far from the signal source, Redmi 9A It is better to switch to 2.4 GHz to maintain connection stability.
Managing saved networks and auto-connection
The smartphone remembers all the networks you've ever connected to, which is convenient for automatically connecting to your favorite locations. However, over time, the list can grow, and the phone will try to connect to weak or unresponsive networks, ignoring stronger signals. Redmi 9A You can manage this list in the Wi-Fi menu.
To remove an unnecessary network, tap the arrow next to its name (or the gear icon, depending on your MIUI version) and select "Forget Network." Your phone will then delete the saved password and stop attempting to connect automatically.
- 🗑️ Regularly clear the list of your neighbors' networks that you connected to while visiting.
- 🔄 The "Forget Network" feature also helps reset authorization errors if the password has been changed on the router.
- 🚫 Disable the "Turn on Wi-Fi automatically" option if you want to control when Wi-Fi connects to save battery life.
There's also a useful "Wi-Fi Assistant" feature that can be built into the MIUI skin.

⚠️ Attention: If your phone displays "Obtaining IP address..." and then returns an error, the problem is most often an address conflict in the router or an overflowing DHCP table. Try rebooting the router or setting up a static IP address on your phone.
If your Wi-Fi is slow, you can use the built-in optimization tool. In the Security app on Redmi 9A There's a "Speed" section that may suggest optimizing your network settings. It's also helpful to check if data saving mode is enabled, which can limit background app activity.
If all else fails, the last resort is resetting your network settings. This will reset all network settings (Wi-Fi, Bluetooth, mobile data) to factory defaults, but will not delete your personal files, photos, or contacts. You'll have to re-enter passwords for all Wi-Fi networks.
How to reset network settings on Redmi 9A?
Go to Settings -> Connection & Sharing -> Reset Wi-Fi, Mobile Networks, and Bluetooth. Confirm the action and wait for the modules to reboot.
Optimizing energy consumption and security
The wireless module is one of the main energy consumers in a smartphone. To Redmi 9A To ensure your phone lasts longer on a single charge, pay attention to the power-saving settings related to Wi-Fi. MIUI aggressively manages background processes, which can lead to connection drops in sleep mode.
To solve the background tearing issue, go to the settings of the app that needs to be running constantly (for example, a messenger), and in the "Battery" section, select "No restrictions." This will prevent the system from "killing" the process when the screen is locked, ensuring a constant Ping and instant notifications.
From a security standpoint, always use WPA2 or WPA3 encryption. Avoid connecting to open public networks without a password for banking purposes. If you must use public Wi-Fi, it's best to use a VPN service that will encrypt all traffic between you. Redmi 9A and the Internet.
Regularly updating your MIUI system via the "About phone" menu ensures you receive the latest security patches that address vulnerabilities in the network stack. Don't ignore notifications about available updates, especially if they are marked as important for security.
Why doesn't Redmi 9A see the 5 GHz network?
Make sure your router is actually broadcasting a signal in this range and that the channel isn't hidden. Also, check the region in your router settings: some countries restrict the use of certain 5 GHz channels, and if the region on your phone and router don't match, the network may not be visible.
How to speed up slow Wi-Fi on your phone?
Try changing the channel in your router settings to a less congested one (use Wi-Fi analyzer apps). Disable the VPN on your phone if you don't need it, and close apps that consume background data. Switching to the 5 GHz band if you're close to the router can also help.
What to do if the phone connects, but there is no internet?
Check if there's internet access on other devices. If so, the issue lies with the DNS or IP settings on your phone. Try setting a static DNS (e.g., Google's: 8.8.8.8) in the advanced Wi-Fi settings on your Redmi 9A.
