Modern routers Xiaomi And Redmi By default, wireless routers are configured to automatically select optimal wireless network parameters. This is convenient for most users who simply want to "set it and forget it." However, in some cases, this automatic setup can malfunction: older devices stop detecting the network, data transfer speeds drop, or interference from neighboring routers occurs. In such situations, manually adjusting the protocol settings is the only reliable solution.
Change of standard Wi-Fi Allows you to force the router to switch to a mode compatible with your equipment or, conversely, activate maximum performance for new devices. This process doesn't require extensive programming knowledge, but it does require careful attention when navigating the web configurator interface. In this article, we'll cover in detail how to access the hidden settings of the wireless module and select the correct operating mode.
Before making any changes, it's important to understand that different standards provide different ranges and speeds. For example, the mode 802.11b is the slowest, but has the best penetration ability through walls, while 802.11ac (or Wi-Fi 5) delivers gigabit speeds, but over short distances. Choosing the right mode can dramatically change your home network experience.
Why do we need to change the wireless network standard?
The main reason why users delve into the depths of router settings Xiaomi Mi Router or Redmi — these are compatibility issues. It's quite common for a new, powerful laptop to work perfectly, but an older printer or smart light bulb simply won't connect to the network. This happens because modern routers, by default, can only use secure or new encryption and data transfer protocols that older hardware physically doesn't support.
The second important aspect is connection stability. In apartment buildings, the airwaves are clogged with signals from dozens of neighboring access points. If your router is operating in mixed mode 802.11 b/g/n, it is forced to spend resources on serving slow clients, which can slow down the entire network. Switching to the mode Only N or Only AC Allows you to cut off unnecessary connections and increase the overall channel throughput for your main devices.
⚠️ Caution: Forcing your router to use a new standard only (e.g., AX or AC only) will prevent devices that don't support that standard from connecting to the network. Make sure all your devices are compatible with the selected mode.
Changing the mode may also be necessary to diagnose problems. If you suspect that a specific standard is causing interference, manually switching helps isolate the fault. For example, the mode 802.11g operates exclusively in the 2.4 GHz band and may interfere with microwave ovens or Bluetooth headsets, while switching to 5 GHz completely eliminates this type of interference.
Preparing to set up your router
Before you begin changing system settings, you need to ensure a stable connection to the router itself. It's best to configure it by connecting a computer or laptop to Xiaomi Router through LAN cableThis will eliminate the risk of connection loss when applying settings, when the wireless module reboots or changes frequency.
You will also need administrator rights. If you've never changed the web interface password, try the default combinations, which are often printed on a sticker on the bottom of the device. For devices released for the global market, this may be admin, and for Chinese versions, the password is often the same as the Wi-Fi password or is set upon first launch.
☑️ Preparing for setup
Don't forget to save your current configuration if your router allows you to back up your settings. While changing the Wi-Fi standard rarely results in a complete reset, it's always a good idea to be on the safe side. Also, keep a list of MAC addresses of important devices handy in case you need to reconfigure filtering.
Login to the web management interface
The authorization process in the interface MiWiFi or new firmware Xiaomi Home may vary depending on the software version. Open any browser and enter the router's IP address in the address bar. By default, for most models Xiaomi And Redmi the address is used 192.168.31.1 or domain name miwifi.com.
If the page doesn't load, check the network adapter settings on your computer. It should obtain an IP address automatically via DHCPIn some corporate networks or when using static IP addresses, it may be necessary to temporarily switch to dynamic address acquisition.
After entering the correct password, you'll be taken to the status center's main page. This displays the current speed, number of connected devices, and port status. This is where we'll access the advanced settings. The interface may be in Chinese if you purchased a device for the Chinese domestic market, but the menu structure remains logical.
What to do if you forgot your administrator password?
If you don't remember the password to access the settings, you'll have to perform a factory reset. To do this, locate the reset hole on the router while it's turned on and press it with a paperclip for 5-10 seconds until the indicator light flashes. After this, the router will reset to the factory password indicated on the sticker.
Finding the Wireless Settings Section
Firmware interfaces Xiaomi have undergone changes, so the location of the settings you're looking for may vary. In classic firmware (blue or green interface), you need to find the "Settings" tab, then go to the "Wi-Fi" or "Wireless" section. In newer versions of the interface and in the app Mi Home The logic is similar, but the items may be called "Network Settings".
You are interested in the parameter which is called in the English version Wireless Mode or "Mode." This is where the choice between legacy standards and modern protocols lies. This option is often hidden within the "Professional Settings" or "Advanced Settings" submenus, as the manufacturer believes that the average user doesn't need this knowledge.
Please note that the settings for the 2.4 GHz and 5 GHz bands are separate. You will need to repeat the standard selection procedure for each frequency separately if your router is dual-band. Don't confuse them, as the requirements for devices in these bands are significantly different.
| Standard | Range | Max. speed (theoret.) | Compatibility |
|---|---|---|---|
| 802.11b | 2.4 GHz | 11 Mbps | Very high (old devices) |
| 802.11g | 2.4 GHz | 54 Mbps | High |
| 802.11n | 2.4 / 5 GHz | 600 Mbps | Universal |
| 802.11ac | 5 GHz | 6.9 Gbps | Modern smartphones and PCs |
Choosing the optimal Wi-Fi standard
In the mode drop-down list, you will see several options. The most common choice is 802.11 b/g/n mixedThis mode ensures maximum compatibility: both an ancient phone from 2005 and the latest flagship will be able to connect to the network. However, the presence of older standards (b and g) may slightly reduce overall network performance due to the limitations they impose.
If you don't have any devices in your home that are older than 10 years, it makes sense to switch to the mode 802.11 n only (for 2.4 GHz) or 802.11 ac only (for 5 GHz). This will remove unnecessary service frames that the router is forced to transmit to support older clients. The result will be a more stable ping and fewer connection drops during peak hours.
⚠️ Note: Firmware interfaces are subject to change. If you don't find an exact match for the item names, look for synonyms or similar icons. Always check the official documentation for your specific router model, as functionality may vary.
For the 5 GHz band, the de facto standard is now 802.11ac (Wi-Fi 5) or new 802.11ax (Wi-Fi 6) in top models Xiaomi AIoTForced mode setting AC only ensures that no device is stuck at a slow speed, but will disable the ability to connect to gadgets that don't support 5 GHz.
Save settings and reboot
After selecting the desired mode, click "Apply" or "Save." The router will warn you that the wireless network will be rebooted. This is normal: the Wi-Fi module needs to completely adapt to the new protocol. At this point, all wireless devices will lose connection for 10-20 seconds.
If you configured the router via Wi-Fi, the connection will be disconnected immediately after pressing the button. You'll need to find your network again in the list of available networks and connect to it. If the password hasn't been changed, the device will connect automatically, but using the new data transfer standard.
Check the network's functionality on different devices. Run a speed test on your smartphone and laptop. If the speed increases or connection drops disappear, the setup was successful. If the devices stop seeing the network, return to the settings and select a more compatible mode (e.g., mixed).
Common problems and their solutions
One of the common problems after switching standards is the inability to connect certain devices. For example, you switched to N only, and a smart socket that works only on 802.11b/g, stopped responding. There's only one solution: return to mixed mode. b/g/nSmart technology is often capricious about new protocols.
Another nuance is the channel width. When changing the standard, the router can automatically change the channel width (20, 40, or 80 MHz). In a noisy 2.4 GHz environment, it's better to force it to 20 MHz for stability, even if the standard N Allows more. In the 5 GHz band, feel free to set it to 80 MHz for maximum speed.
If after all the manipulations the router Xiaomi If your router is acting erratically, overheating, or constantly rebooting, the problem may lie not in the settings, but in the firmware. Try updating your router's firmware to the latest version via the "Status" or "System Update" sections. Sometimes, bugs in older firmware versions prevent certain standards from working correctly.
Why doesn't my old laptop see the network after changing the settings?
Most likely, your laptop is equipped with an older network card that only supports 802.11b or 802.11g. If you've switched your router to "N-only" or "AC-only" mode, the old adapter will physically be unable to detect the signal. Reset the router to mixed mode.
Does changing the standard affect the Wi-Fi range?
Indirectly, yes. The 802.11b standard has better sensitivity and range at lower speeds. The transition to higher standards (N, AC) focuses on speed, which can slightly reduce the range in difficult conditions (like concrete walls), although the transmitter power remains the same.
Is it possible to use different standards at the same time on one router?
Yes, if your router is dual-band. You can configure the 2.4 GHz band in mixed b/g/n mode for your smart home, and switch the 5 GHz band to AC-only mode for your gaming PC and TV. This is the optimal strategy.
Will the router reset if I turn off the light while saving?
Modern routers Xiaomi They have protection against failures, but interrupting the process of writing the configuration to flash memory could theoretically lead to a software failure. Avoid turning off the power while the activity indicator is lit or the system light is flashing.
Do I need to reset my Wi-Fi password after changing the standard?
No, the network name (SSID) and password remain the same. Only the internal data transfer protocol changes. Your devices will connect automatically once the router finishes rebooting its wireless module.
