The situation when your Redmi 9 Displaying the Wi-Fi icon but not loading browser pages is one of the most annoying problems for Android users. The screen shows "Connected," but no actual data exchange with the outside world occurs. This can be caused by anything from a simple router malfunction to more complex settings conflicts within the operating system. MIUI.
Users often mistakenly assume that the problem lies solely with their smartphone, forgetting to check the network status or provider settings. In most cases, you can fix the issue yourself without having to contact a service center. It's important to rule out software errors, DHCP server issues, and IP address conflicts.
In this article we will look at all the possible reasons why Redmi 9 If your Wi-Fi connection isn't working, we'll offer specific action steps. You'll learn how to properly reset network settings, change DNS, and check your router configuration to restore a stable connection.
Basic diagnostics and hardware reboot
The first and most effective step in solving 90% of network problems is a complete reboot of all involved devices. Smartphones XiaomiAndroid-based devices tend to accumulate temporary errors in the network module when left running for long periods of time without being turned off. Simply turning the screen on and off won't help—a full system reboot is required.
Furthermore, routers are also mini-computers with their own operating system, which can freeze or become overloaded with error logs. If your Redmi 9 If the router says "Connected, no internet access," start by unplugging the router for 10-15 seconds. This will fully discharge the capacitors and clear the device's RAM.
⚠️ Important: When rebooting your router, make sure you actually turn off the power and not just press the reset button. Holding the reset button for a long time may reset the device to factory settings, which will require you to reconfigure your internet connection with your ISP.
After turning on the router, wait 2-3 minutes for all services to fully load. Then, on your phone, go to Settings → Wi-Fi, click on your network name and select "Delete" or "Forget." This is a critical step, as it deletes the saved connection profile and any possible configuration errors.
Problems with DHCP and static IP address
One of the most common reasons why Redmi 9 If the router doesn't see the Internet, there is an IP address conflict or a failure in the router's DHCP server. DHCP Automatically assigns unique addresses to all connected devices. If this process is disrupted, the phone may receive an address already taken by another device, or may not receive one at all.
To eliminate this issue, try manually entering a static IP address in your smartphone's Wi-Fi settings. To do this, in the Wi-Fi menu, tap the arrow next to your network name or select "IP Settings" and switch the mode from DHCP to "Static."
In the fields that appear, you must enter the correct information corresponding to your local network. Typically, the gateway (router) has an address of 192.168.0.1 or 192.168.1.1. The phone address should differ from the gateway only by the last digit, for example, 192.168.0.150.
☑️ Setting up a static IP
If the problem persists after setting the address, the router's address range may be too small or occupied. In this case, it might be worth reverting to automatic IP acquisition (DHCP) and rebooting the router again to refresh the address pool.
DNS Failure: How to Change Nameservers
It often happens that the connection to the router is established, the IP address is obtained, but websites do not open. This is a classic sign of problems with DNS (Domain Name System). DNS servers translate human-readable addresses (e.g., yandex.ru) into the digital IP addresses of servers. If your provider provides slow or non-functional DNS by default, Redmi 9 will show no internet connection.
The solution is to configure reliable public DNS servers, such as those from Google or Cloudflare. This often speeds up page loading and resolves the "No internet access" issue. You can do this in the same Wi-Fi settings where you changed the IP address type.
| DNS provider | Primary DNS | Secondary DNS | Peculiarities |
|---|---|---|---|
| Google Public DNS | 8.8.8.8 | 8.8.4.4 | High speed, reliability |
| Cloudflare | 1.1.1.1 | 1.0.0.1 | Focus on privacy and speed |
| Quad9 | 9.9.9.9 | 149.112.112.112 | Blocking malicious websites |
| OpenDNS | 208.67.222.222 | 208.67.220.220 | Flexible content filtering |
Enter the selected addresses into the DNS 1 and DNS 2 fields in your Wi-Fi network settings on your Redmi 9. After saving, try accessing the website. If the pages load, the issue was with your provider's nameservers.
Date, time, and security certificate conflicts
Modern security protocols such as WPA2 And WPA3, as well as HTTPS encryption of websites, critically depend on the correct system time. If your Redmi 9 If the date or time is incorrect, browsers and system services will consider security certificates invalid and block access to the network.
Check your date and time settings by going to Settings → Advanced → Date and TimeMake sure "Use network time" (Automatic) is enabled. If this feature is already enabled, try disabling it, setting the wrong date, and then re-enabling automatic sync.
It's also worth paying attention to antivirus or system cleaning applications, which may inject their own certificates and block traffic. If you've recently installed such utilities, try temporarily uninstalling them or disabling Wi-Fi protection.
⚠️ Note: The MIUI interface may vary depending on the firmware version. If you can't find "Date & Time" in the "Advanced" section, try searching for "time" in the settings.
Resetting network and radio settings
If simple solutions don't help, the system may have accumulated deep network interface configuration errors. In this case, a temporary solution is to reset the network settings. This will reset Wi-Fi, Bluetooth, and mobile data settings to factory defaults, but will not delete your personal files, photos, or apps.
To perform a reset on Redmi 9, go to the menu Settings → Connection and sharing → Reset Wi-Fi, mobile networks, and BluetoothThe system will warn you that all saved Wi-Fi passwords will be deleted. Confirm the action and wait for the modules to reboot.
After this procedure, your phone will be as good as new in terms of network connections. You'll need to re-enter your Wi-Fi router password. This eliminates any software glitches related to caching old or conflicting connection profiles.
What happens when you reset your network?
Resetting network settings deletes all saved network SSIDs, Bluetooth device passwords, and mobile operator APN settings. Personal data (contacts, photos, apps) remains intact. This is a safe procedure for troubleshooting network errors.
In some cases, especially after a firmware update MIUIA deeper reset may be necessary. However, before resorting to a full reset (hard reset), it's worth checking whether the router is blocking your device by MAC address.
Checking router settings and MAC address filtering
The problem may not be with your phone, but with the router settings itself. The filtering function MAC address allows the network owner to deny or allow access to specific devices. If your Redmi 9 accidentally blacklisted, it will connect to Wi-Fi, but the Internet will not be transmitted.
To check, log into your router's web interface (usually at 192.168.0.1 or 192.168.1.1) from any other device with network access. Find the "Wireless," "Wi-Fi Settings," or "MAC Filter" section. Make sure your phone's MAC address (you can find it in Settings → About phone → General information) is not blocked.
It's also worth checking the number of connected clients. Some budget routers have a limit on the number of simultaneously connected devices. If the limit is reached, new devices (like your Redmi 9) can connect locally but won't be able to access the external network.
The Impact of MIUI Firmware and Power Saving
operating system MIUI is known for its aggressive power-saving policy. The "Battery" feature can limit background network activity, considering it to be draining battery power. This can result in Wi-Fi being technically enabled, but data transfer being suspended by the system.
Go to Settings → Battery and check your operating mode. If "Power Saver" or "Super Power Saver" mode is enabled, try switching to "Balanced" or "Performance" mode. Also, in battery settings, find your browser or system app and make sure it's allowed to run in the background.
Sometimes the problem lies in bugs in the Android version itself or the MIUI shell. Check for system updates in the section Settings → About phone → MIUI versionManufacturers regularly release patches to fix network driver errors.
Why does Redmi 9 see 5GHz Wi-Fi but not connect?
The Redmi 9's Wi-Fi module supports dual-band connectivity, but channel conflicts can occur. If the router broadcasts a 5 GHz signal on a channel the phone doesn't support (for example, DFS channels), the connection will be unstable. Try setting the router's settings to channel 36, 40, 44, or 48.
Can a virus block the internet on a phone?
Yes, malware can change proxy or DNS settings, redirecting traffic. If the problem occurred after installing an unknown app, scan your phone with an antivirus (such as Dr.Web or MIUI's built-in security scanner) and remove suspicious programs.
What should I do if the Internet works via 3G/4G, but not via Wi-Fi?
This indicates that the problem is localized in the router-phone connection. Most likely, it's due to DHCP settings, MAC filtering, or router bandwidth congestion. The mobile network operates independently of the home equipment, so access is possible.
How do I know if my ISP is blocking my router?
ISPs may block access based on a router's MAC address when replacing it. If you've just replaced your router and your Redmi 9 can't connect to the internet through any device, call your ISP's technical support to pair the new equipment.
