The situation when your Redmi 9A The Wi-Fi icon, but with an exclamation point or the message "Connected, no internet access," is one of the most common issues in the MIUI ecosystem. This condition means that the physical connection between the smartphone and the router is established successfully, but the packet data transmission from the provider to the device is blocked or distorted. Users often assume that the phone itself is faulty, but in most cases, the root cause lies in a software conflict or a temporary router malfunction.
Troubleshooting begins with understanding the nature of the connection: the smartphone has received an IP address from the router, but is unable to communicate with the outside world. This could be caused by a static IP address that conflicts with the addresses of other devices on the home network, or by a DNS server failure that cannot resolve domain names into machine-readable IP addresses. Redmi 9A This is more common due to MIUI's aggressive battery optimization, which can prematurely terminate background network service processes.
Before panicking and taking your device to a service center, try simply rebooting your router by unplugging it for 10-15 seconds. In 40% of cases, this resolves the issue, as the router clears its cache and re-requests the settings from your provider. If the router works reliably on other devices, and Redmi 9A If it stubbornly refuses to connect, then the problem is localized in the phone's settings.
Basic reboot of network modules and router
The first step in troubleshooting any network anomalies should be a full reboot of all devices involved. Don't just turn off your smartphone's screen; you need to perform a full system reboot. AndroidPress and hold the power button and select "Power Off," wait 30 seconds, and then turn the device back on. This will forcefully terminate all frozen network service processes and clear any temporary errors in the Wi-Fi module.
Particular attention should be paid to the router, as it is the gateway to the outside world. Even if it has been working flawlessly for several years, its RAM may be full of error logs. Unplug the router's power cable from the outlet, wait at least 15 seconds, and then plug it back in. Wait until all the indicators light up before checking the connection status. Redmi 9A.
⚠️ Important: If the global access indicator (usually a planet or the letter "e") flashes or stays red after rebooting your router, the problem lies with your internet service provider. In this case, changing your phone settings is useless—call technical support.
There is also a method to "soft reset" the radio module directly in the MIUI interface. Go to Settings → Wi-Fi, turn off the wireless network switch and wait 10 seconds. Turn it back on and try connecting to the access point. This method helps if the Wi-Fi module driver has malfunctioned after waking from sleep mode.
Forget the network and reconnect
Often, the lack of internet access is caused by desynchronization of encryption keys or changes to security settings on the router (for example, changing the password or encryption type from WPA2 to WPA3). In this case, Redmi 9A It's trying to use old, saved data that the router no longer accepts, blocking network access. The solution is to delete the old network profile.
To perform this operation, go to the menu Settings → Wi-FiFind your home network in the list and tap the arrow to the right of its name (or the gear icon, depending on your MIUI version). In the menu that opens, select "Delete" or "Forget this network." Confirm your action, and the network will disappear from the list of saved networks.
After deleting the profile, scan for available networks again. Select your access point and re-enter the password, paying close attention to the capitalization. When entering the password, it's helpful to click the "eye" icon to ensure you've entered the correct characters. After a successful connection, the system will re-query the IP address and DNS servers, which often resolves configuration conflicts.
- 🔑 Deleting a network erases the saved password and static IP settings for that specific access point.
- 🔄 Reconnecting forces the smartphone to go through the authorization procedure again and obtain a fresh lease from the DHCP server.
- ⚙️ If the problem persisted due to changing the router's encryption type, this step is guaranteed to fix the error.
☑️ Reconnection checklist
Reset network settings to factory defaults
If simple methods do not help, it may be in the system files Android Network interface configuration errors have accumulated. The "Reset Wi-Fi, mobile network, and Bluetooth" function returns all network settings to their factory defaults. This is a more comprehensive operation than simply "forgetting a network," as it affects the system's routing tables.
To perform a reset, open Settings → Connection and Sharing → Reset Wi-Fi, Mobile Network, and BluetoothThe system will warn you that all saved Wi-Fi passwords, Bluetooth pairings, and mobile network settings will be deleted. Tap the "Reset settings" button and enter your unlock pattern or PIN to confirm.
After rebooting, your phone will be "clean" in terms of network settings. You'll need to re-enter passwords for all Wi-Fi networks and re-pair any Bluetooth devices (headphones, watches). However, this step often solves complex issues where the phone says "Connected," but pages won't load in any browser.
⚠️ Note: This procedure does not delete your personal files, photos, or apps. It only affects system connections and paired devices.
This method is highly effective when switching between different routers or after changing providers, when the phone still has some old settings. For owners Redmi 9A This is also a way to work around MIUI bugs related to network prioritization.
What happens when you reset your network?
A reset deletes configuration files in the /data/misc/wifi directory. This includes wpa_supplicant.conf, which stores encryption keys. The system regenerates MAC addresses for scanning (if randomization is enabled) and clears the DNS cache.
Setting up static IP and DNS
One of the common causes of the "no internet access" error is an IP address conflict. By default Redmi 9A Obtains an address automatically (DHCP). If the router mistakenly assigns the same address to another device, your phone will be isolated. The solution is to manually assign a static IP address, choosing a free range.
Go to your Wi-Fi network settings (the arrow next to the name). Find "IP Settings" and switch it from "DHCP" to "Static." This will open the data entry fields. The "Gateway" field usually corresponds to the router's address (often 192.168.0.1 or 192.168.1.1). In the "IP Address" field, enter an address from the same subnet, but with a unique ending, for example, 192.168.1.157.
Pay special attention to the DNS fields. Providers often provide their own DNS servers, which can be slow or block access. Try using public and fast servers from Google or Cloudflare. In the "DNS 1" field, enter 8.8.8.8, and in "DNS 2" - 1.1.1.1This often "revitalizes" the Internet in places where it formally exists but does not work.
| Parameter | Meaning (Example) | Description |
|---|---|---|
| IP address | 192.168.1.157 | Your Redmi 9A's unique network address |
| Gateway | 192.168.1.1 | Your router's address |
| Network prefix length | 24 | Standard value for home networks |
| DNS 1 | 8.8.8.8 | Google's primary DNS server |
| DNS 2 | 1.1.1.1 | Cloudflare Alternative Server |
Date, time and power saving mode
It would seem that time has nothing to do with the internet. However, the security protocols (SSL/TLS) used to encrypt traffic are strictly tied to the current time. If on your Redmi 9A If the date is incorrect (for example, it's 2015), browsers and applications will consider security certificates invalid and block the connection, returning an access error.
Check your time settings by going to Settings → Additional settings → Date and timeMake sure "Use network time" is enabled. If the date is incorrect, disable this option, set the correct values manually, and then enable sync again. This often restores YouTube and browser functionality immediately.
The second important aspect is power saving mode. MIUI is known for its aggressive battery saving policy. If "Ultra" or "Power Saving" mode is enabled, the system may limit background network activity, considering them power-hungry. As a result, Wi-Fi works, but data transfer is blocked.
- 🔋 Disable power saving mode to check: go to
Settings → Batteryand select the "Balanced" or "Performance" mode. - 📱 Check specific apps: In the battery menu, find the list of apps and make sure that the browser or messenger app is not limited to "Background activity is limited."
- ⚡ The Game Booster feature may also block background downloads: check the Security app settings.
⚠️ Note: The MIUI interface may differ depending on the firmware version (Global, Russia, China). Menu items may have slightly different names, but the logic remains the same—look for the sections related to Battery and Date & Time.
Hard reset as a last resort
If none of the software methods helped, and the error “Wi-Fi is connected, but there is no Internet access” appears on Redmi 9A If the error persists, the operating system files may be damaged. In this case, a radical but effective solution remains: a full factory reset. This will erase all data from the phone, returning it to its "out of the box" state.
Before performing this procedure, be sure to back up all important data (contacts, photos, documents) to Mi Cloud, Google Drive, or your computer. After the reset, it will be impossible to recover deleted files without a backup. Make sure the battery charge is at least 50%.
To perform a reset, go to Settings → About phone → Factory data reset → Erase all dataThe system will ask you to enter your password and confirm the warning. After rebooting, the phone will begin a lengthy wipe and installation process. Reset your Wi-Fi—if the issue was a software glitch, it will resolve itself.
Reset path (English version):
Settings → About phone → Factory reset → Erase all data
Is it possible to reset the settings using buttons?
Yes, if your phone won't turn on, turn off your Redmi 9A and press and hold Volume Up + Power. In the Recovery menu, select Wipe Data → Wipe All Data. This requires your Mi account password.
It's worth noting that if the problem persists even after a full reset and clean installation, there's a high probability of a hardware fault in the Wi-Fi module. This could be a loose antenna cable (a common issue after drops) or a faulty communication chip. In this case, software solutions are ineffective, and a visit to a service center for hardware diagnostics is required.
Why doesn't Redmi 9A see the 5 GHz network?
The Redmi 9A is equipped with a budget Wi-Fi module that only supports the 2.4 GHz band. It physically cannot detect or connect to 5 GHz networks. If your router only broadcasts the 5 GHz band, the phone simply won't detect it. You need to enable 2.4 GHz network broadcasting in your router settings.
How do I know if my router is blocking my phone?
Access your router's web interface (usually through a browser at 192.168.0.1). Find the "Wireless" or "Client List" section. If your Redmi 9A shows up as "Blocked" or "Blacklisted," MAC address filtering is enabled. Add your phone's MAC address (found in Wi-Fi settings → Wi-Fi Assistant) to the whitelist.
Does the case affect the Wi-Fi signal?
Yes, some materials can shield the signal. Metallic cases, cases with magnetic closures, or very thick rubberized cases can weaken the signal, resulting in packet loss and a "no internet access" error. Remove the case and check the network.
What to do if only a reboot helps?
If the internet connection only appears after rebooting the router and then disappears again an hour later, the problem may be overheating or the router's memory is full. Try updating the router's firmware or upgrading to a more powerful model if you have many connected devices.
