When a Xiaomi router has blocked a device, it often takes users by surprise: You try to connect your phone or laptop to your home network, but instead of the usual connection, you get an error "failed to connect" or a status "Get a Received". IP-This does not always mean that the gadget is broken or the router is malfunctioning.
Most often, the cause is an activated blacklist function (Blacklist) or an enabled filter mode by MAC-In such cases, the router deliberately ignores requests from a particular hardware, even if the Wi-Fi password is entered perfectly correctly.
To solve the problem, you will need access to a web interface or a mobile application Mi Wi-Fi. We will detail the algorithms of actions for various scenarios, from accidental lockdown to complex network conflicts. Follow the instructions carefully so that you do not disrupt the entire home network.
Reasons for blocking devices by Xiaomi router
Before we take action, we need to understand why Xiaomi’s router blocked the device, and there are several main scenarios that lead to this result, most often manually configuring the network owner, which the administrator may have forgotten about, or automatic protection against unauthorized access.
One of the most common reasons is the inclusion of filtering by MAC-In this mode, the router compares the unique ID of the connected gadget's network card to the list of allowed ones, and if your device is not on the whitelist, access will be closed. It is also possible that a device has been added to Blacklist due to suspicious activity or manual addition.
Sometimes the problem lies in the software failure of the router itself or overflow of the table. DHCP-If too many gadgets are trying to connect to the network at the same time, the router may simply not give out a new one. IP-In rare cases, the router’s antivirus protection initiates a block if the traffic seems suspicious to the router.
- 🚫 Activated Blacklist mode for a specific MAC-address.
- 🔒 Strict filtration is on MAC-Addresses (Whitelist mode).
- 📉 The table is full. DHCP or the pool of addresses issued has run out.
- 🔄 Software failure of the firmware of the Xiaomi router.
Checking the list of blocked customers
The first step to unlock is to diagnose the current state of the network, you need to log in to the router control panel, which can be done through the browser by entering 192.168.31.1 or miwifi.com, or through the official Mi Wi-Fi app on your smartphone, logging in requires an administrator password.
Once you log in, find a section that's usually called "Wi-Fi settings" or "Customer management." Xiaomi routers often have a tab called "Blocked Devices" or "Blacklist," and that's where you see the devices that are being forced to access, and if you see your device on this list, you have to remove it.
Pay attention to the status of the connection. Sometimes the device is not completely locked, but is limited in speed or Internet access (parental control function). Check if there is a ban icon or a red mark next to your gadget. Deletion from the lock list usually occurs in one touch.
💡
If you can’t log in to the router’s settings, try connecting to it through it. LAN-cable – this will provide access even in case of problems with the Wi-Fi module.
In the Mi Wi-Fi app, the interface looks more friendly. Go to the Devices tab, select suspicious or your gadget. If it's restricted, you'll see a notification. Click on the Access Control button and select "Allow" or "Delete from the blacklist."
Filtering settings by MAC-address
If simply removing from the blacklist is not enough, filter mode may be activated. MAC-It's a more stringent security mechanism, and unlike a blacklist that forbids access to a select few, it can only allow access to a predetermined set of devices, and everyone else, even with the right password, will be rejected.
To check and change these settings, go to the Wi-Fi Settings section. → Filtration MAC-You'll see two main modes here: Blacklist (no one selected) and Whitelist (no one selected) and if you have a Whitelist activated and your device isn't there, the router will block it.
To unlock, you either need to add MAC-Your device's address is whitelisted, or you can turn off the filtering function completely. MAC-You can use the address in your phone settings (about phone or status) or on a sticker under the laptop case, and type it in accurately, using a format like this: AA:BB:CC:11:22:33.
☑️ Verification MAC-filtering
After applying the new settings, the router may take a few seconds to reboot network services. If you are not sure about your actions, it is better to simply turn off the filter completely.
Resetting network settings on the client device
Sometimes the problem is not the router, but the cache of network settings on the smartphone or laptop itself, the device can "remember" old configurations or erroneous encryption keys, which leads to conflict, in which case the router can perceive repeated attempts to connect as an attack and block the port.
On Android devices, the effective solution is to forget the network. Go to your Wi-Fi settings, select your network, click "Delete" or "Forget." Then re-enter your password. This action clears the saved certificates and IP-configuration for this access point.
A more radical, but often helpful, method is to reset all network settings of the device, which will bring Bluetooth, mobile and Wi-Fi settings back to factory values. → Mainstream → Removing or resetting iPhone → Reset → Reset network settings. On Android, the path may be different, but it's usually in the System section. → Reset.
Once you reset, be sure to restart the client device itself, which ensures that all network services start anew and try to get fresh. IP-address DHCP-This often solves the problem when the router "hangs" on the old state of the client.
Use of guest Wi-Fi network
If standard unlocking methods don't help, or you can't get into the main router settings, a great workaround is to create a Guest Network, a feature found in almost all modern Xiaomi models. The guest network works independently of the main one and has its own access rules.
Guest network is isolated from your main LAN, which increases security. Devices connected to guest Wi-Fi do not see other gadgets in the house (printers, NAS-storage facilities), but have full Internet access, which is ideal for temporarily connecting a problem device.
You can turn on the guest network in the Mi Wi-Fi app or through the web interface in the Wi-Fi settings → Guest network. Set it up with a separate name (SSID) and password. Since this network applies a separate address pool and separate filtering rules, the locked device is likely to connect without problems.

Complete reset of Xiaomi router
When software bugs become critical and none of the methods work, the final argument is a complete reset of the router to the factory settings (Hard Reset), which will remove all your settings, including Wi-Fi passwords, PPPoE data from the provider and lock lists.
To reset, find a small hole on the router body that says Reset. Press it with a paper clip or pin and hold it for 5-10 seconds until the system indicator flashes orange. Release the button and wait for the device to restart. The router will return to the "out of the box" state.
Once reset, you will need to reset your Internet connection. Be prepared to enter your ISP login and password if you use a PPPoE, L2TP or PPTP connection type. If the ISP uses Dynamic IP (DHCP), the Internet will start automatically once the cable is connected to the WAN port.
| Parameter | Before dumping. | After discharge |
|---|---|---|
| Wi-Fi password | Your current | Not available (or standard with a sticker) |
| Administrator password | Your current | Not installed (reinvented) |
| Blacklist | Contains lockdowns | Cleared. |
| Provider settings | Save. | Removed (entry required) |
⚠️ Warning: Before performing a full reset, make sure you have an ISP contract on hand.You may need a login and password to access the network that are not stored on the router after the reset.
Frequently Asked Questions (FAQ)
Why does a router write “incorrect password” when the device is locked?
Can antivirus software on your computer block your connection to Xiaomi router?
What if I forgot the router administrator password?
Does the number of connected devices affect the lock?
⚠️ Warning: After resetting your router, be sure to change your default administrator password. Factory passwords are often known to hackers, and your network can become vulnerable to attacks in the first minutes of operation.
Restoring access to the network is a process that requires consistency. Start by checking the blacklist in the application, then try to forget the network on the phone. If that doesn't work, then resort to a complete router reset, and managing access lists properly will allow you to avoid similar situations in the future.
