Owners of Xiaomi, Redmi, and POCO smartphones often encounter a mysterious notification stating that the number of Wi-Fi requests is limited. This is a system error built into the OS. MIUI, can completely block internet access, even if the router is working properly. The user sees the network icon, but pages in the browser don't load, and applications require a connection.
The core of the problem lies in the Android security mechanism, which MIUI interprets the network too aggressively. The system monitors the number of times a device attempts to contact an access point or DNS server. If too many requests are received in a short period of time without a successful response, the algorithm marks the network as potentially dangerous or overloaded and forcibly disconnects.
This most often occurs after a firmware update or a change in router settings. It's important to understand that this isn't a hardware failure, but a software conflict. A critical factor is the mismatch between the security settings on the router and the phone, which causes a cyclical repetition of authorization attempts. In this article, we'll discuss how to diagnose the cause and restore stable internet.
The mechanism of protection and the reasons for blocking
The Android operating system has a built-in network availability check protocol. Periodically, the device sends requests to special servers (usually Google or Xiaomi) to ensure that the internet is actually available and not just a local network. In standard Android, the threshold for such requests is quite high, but in MIUI shell It is often lowered by developers to save battery power.
When a phone tries to connect, but the router takes a long time to respond or responds with an error, the smartphone begins to "storm" the network with repeated requests. The system detects this barrage of requests and decides the network is unstable. As a result, a blocking mechanism is activated, and you see a restriction message. This is a protective mechanism designed to prevent the communication module from freezing, but it often malfunctions.
The main causes of this failure can be related to both the phone's software and the router's configuration. For example, the use of outdated encryption protocols or an overflowing network settings cache can be a trigger.
- 📡 IP address conflict on a local network, when two devices try to occupy the same address.
- 🔒 Mismatch in encryption type (e.g. WPA2/WPA3) between the router and smartphone.
- 📱 Errors in the system Security app or MIUI antivirus.
- 🔄 Failure of the DNS servers specified by default by the operator.
⚠️ Attention: If you recently updated your router's firmware, the issue may be related to new security settings that your phone is interpreting as a threat. Check your router's logs, if possible.
Basic troubleshooting methods
The first step should always be to perform simple steps, which resolve the issue in 80% of cases. Don't rush to reset your phone to factory settings. Often, simply shaking the network connection is enough to reset the failed request counter.
Start by completely ignoring the network. Go to Wi-Fi settings, tap your network name, and select "Delete" or "Forget." Then, restart your smartphone. This clears the local cache of saved connection parameters and forces the communication module to re-establish a handshake with the router.
If deleting the network doesn't help, try rebooting the router itself. Unplug it from the power outlet for 10-15 seconds. This will clear the router's RAM buffer and reset the ARP table, which may have accumulated addressing errors.
☑️ Basic network diagnostics
It's also worth checking if Airplane Mode is enabled on your phone. Sometimes the Wi-Fi module gets stuck in an in-between state. Enable Airplane Mode for 10 seconds, then disable it. This will force a reconnection of all the device's radios.
Setting up a static IP address
One of the most common causes of conflicts is dynamic address allocation (DHCP). The router may assign the phone an address that's already taken by another device, or the phone may fail to obtain the address in time, causing repeated requests. The solution is to manually assign a static IP address.
To do this, go to Wi-Fi settings, click on your network (or the arrow next to it), and find "IP Settings." By default, it's set to "DHCP." Change the value to Static (Static).
Data entry fields will open. You'll need to fill them in with the correct values for your network:
- 🌐 IP address: usually 192.168.1.128 (the last digit can be from 2 to 254).
- 🚪 Gateway: your router's address (often 192.168.1.1 or 192.168.0.1).
- 🔍 Network prefix length: usually 24.
- 🖥️ DNS 1: 8.8.8.8 (Google) or 1.1.1.1 (Cloudflare).
Using public DNS servers from Google or Cloudflare often solves the problem if your ISP blocks or processes requests to their servers slowly. This is especially true for mobile operators that provide home internet.
| Parameter | Value for routers 192.168.1.1 | Value for routers 192.168.0.1 | Description |
|---|---|---|---|
| IP address | 192.168.1.150 | 192.168.0.150 | Unique phone address |
| Gateway | 192.168.1.1 | 192.168.0.1 | Router address |
| Network mask | 255.255.255.0 | 255.255.255.0 | Determines the size of the network |
| DNS 1 | 8.8.8.8 | 8.8.8.8 | Primary name server |
Changing MIUI region and settings
shell MIUI has strict regional restrictions. Some regions (such as India or China) have stricter rules for frequency usage and security protocols. If the wrong region is selected in the phone settings, conflicts with European or American routers may occur.
Try changing the region in your phone settings. Go to Settings → Additional settings → RegionSet the region to "Russia," "Ukraine," or any other European country. After changing the region, the phone will reboot its network modules.
It's also worth paying attention to your date and time settings. If your phone's time is out of sync, SSL/TLS security certificates cannot be verified, causing connection errors and subsequent request throttling.
In some MIUI versions, disabling the "Wi-Fi Assistant" feature may help. This feature automatically switches the phone to mobile data if it detects Wi-Fi is slow, which can cause connection loops.
⚠️ Attention: Changing the region may affect the operation of some system apps and the display of ads in Xiaomi's default apps. Be prepared for changes to your pre-installed services.
Resetting network settings and advanced methods
If simple methods don't help, you'll have to take things a step further. Resetting network settings is a drastic but effective step. It will delete all saved Wi-Fi passwords, Bluetooth pairings, and mobile network settings, returning them to factory defaults.
You can perform a reset through the settings menu. The path usually looks like this: Settings → Connection and sharing → Reset Wi-Fi, mobile networks, and BluetoothConfirm the action and wait for the process to complete.
For advanced users familiar with USB debugging, there's the option to reset network settings via ADB (Android Debug Bridge). This allows you to clear system tables without losing personal data.
adb shell settings delete global captive_portal_http_urladb shell settings delete global captive_portal_https_url
adb shell svc wifi disable
adb shell svc wifi enable
These commands remove the URLs Android uses to check for internet access (captive portal) and force a reboot of the Wi-Fi module. This can help if the system is stuck in the captive portal state.
What to do if nothing helps?
If software solutions fail, the problem may lie with the antenna or Wi-Fi module hardware. It's also worth trying connecting to a 2.4 GHz network instead of 5 GHz, as older modules may not work reliably with newer channel width standards.
Router settings for MIUI compatibility
The problem may not only be with your phone. Routers, especially older models or firmware from providers, may have settings that MIUI perceives it as an error. This primarily concerns the channel width and security mode.
Log into your router's web interface (usually at 192.168.0.1 or 192.168.1.1). Find the Wireless section. Try changing the channel width for the 2.4 GHz band from "Auto" to a fixed value, such as 20 MHzThis will improve connection stability, although it will slightly reduce the maximum speed.
The encryption type is also critical. Make sure it is selected. WPA2-PSK (AES)WPA3 mode or mixed WPA2/WPA3 mode can cause issues on some versions of Android. If you're using WPA3, try temporarily switching to WPA2.
- 📡 Disable the WMM (Wi-Fi Multimedia) feature if present, as it sometimes conflicts with Xiaomi's power saving feature.
- 🔒 Make sure that MAC address filtering is not enabled, which may block the device.
- 🔄 Update your router firmware to the latest version available on the manufacturer's website.
⚠️ Attention: Router interfaces and menu item names may vary depending on the model and firmware version. If you're unsure, consult your router manufacturer's manual or contact your ISP's support team.
Frequently Asked Questions (FAQ)
Why does the error appear only after updating MIUI?
Updates often change network module algorithms and power saving policies. A new version may stricter network response times, treating normal latency as an error. In such cases, resetting network settings or waiting for a patch from the developers can help.
Does antivirus software affect this problem?
Yes, third-party antivirus programs or MIUI's built-in security scanner can intercept network packets for inspection. If the antivirus isn't working properly or its databases are out of date, it may block the server's response, causing a timeout and subsequent request limitation.
Can helfen change DNS server?
Absolutely. ISPs sometimes use slow or overloaded DNS servers. Switching to Google DNS (8.8.8.8) or Cloudflare (1.1.1.1) in the Wi-Fi settings often eliminates connection check delays, preventing MIUI protection from triggering.
Do I need to do a full reset of my phone (Hard Reset)?
This is a last resort. A hard reset should only be performed if nothing else has helped and you're certain the problem is a software glitch, not a router issue. Be sure to back up your data before doing this.
