Owners of Xiaomi and Redmi smartphones often encounter a mysterious item in the settings menu or pop-up messages related to the term Open Wi-Fi SettingsFor many users, this is a cause for concern, as the name sounds like an invitation for strangers to connect to your personal network. In reality, it's a system component responsible for the wireless module's operation in open access point or guest access mode.
Understanding how this mechanism works is critical to security of your dataIf this feature is configured incorrectly, your phone may become vulnerable to attacks or, conversely, you may not be able to share your internet connection with friends without extra passwords. In this article, we'll take a detailed look at what this term means, how to manage access, and the risks of using open networks on devices. MIUI.
Modern versions of the shell HyperOS and earlier MIUI Network settings have a complex structure that can easily become confusing. We'll help you understand where exactly these settings are controlled and why the system sometimes prompts you to enable them. This isn't just a technical detail, but an important configuration element. mobile hotspot.
What does Open Wi-Fi mean?
Term Open Wi-Fi In the context of mobile devices, it means a network that does not require a password to connect. When you see settings related to this mode on Xiaomi Redmi, we're talking about the ability to turn your smartphone into a public hotspot. Unlike secure WPA2/WPA3 networks, Open mode transmits data unencrypted, making it visible to anyone within range.
The system process responsible for these settings often runs in the background, waiting for the user to activate internet tethering. This can be either intentional, like when you want to share your data, or accidentally activated through widgets or a voice assistant. It's important to distinguish between client mode (when you're connected to Wi-Fi) and access point mode (when you're sharing your internet).
⚠️ Warning: Enabling Open Wi-Fi mode on your personal device in public places can lead to your logins, passwords, and correspondence being intercepted by attackers using traffic sniffers.
On devices Redmi Note and series Xiaomi This functionality is tightly integrated with system security services. When attempting to activate an access point, the system automatically checks to see if encryption is enabled. If you see an "Open settings" notification, it may mean the guest network doesn't have a password, which is a potential security hole.
Where can I find open network settings on Xiaomi?
Finding the specific parameters responsible for open access may take time, as developers MIUI The menu structure is constantly changing. Most often, the options you need are hidden in the "Wi-Fi Hotspot" section. To access it, go to your smartphone's main settings and select "Connection and Sharing."
Inside the access point menu, you'll find a switch to change the security type. By default, it's set to WPA2-Personal, which is the correct choice for most cases. However, if you want to create an open network for temporary use, you'll need to change this setting to "No" or "Open," which will enable the appropriate system permissions.
Hidden engineering menus
In some firmware versions, access to advanced Wi-Fi settings can be gained through the engineering menu by entering a special code in the dialer, but this requires root access and may disrupt the operation of the communication module.
It's also worth paying attention to the "Guest Network" feature if your phone supports creating multiple hotspot profiles. In this case, Open Wi-Fi Settings will be specific to an isolated network segment where guests won't have access to your device's core files. This is a more secure option than completely opening the main communication channel.

Risks of using open mode
Using the mode Open Wi-Fi carries serious threats that every smartphone owner should be aware of XiaomiFirst and foremost, this is the possibility of "man-in-the-middle" attacks. An attacker, by connecting to your open network or creating a fake access point with a similar name, can intercept all passing traffic.
Furthermore, open access allows any Nearby device to attempt to connect to your phone. This could lead to hacking attempts through vulnerabilities in file transfer protocols or service providers. AndroidEven if you don't store any sensitive data on your phone, your traffic can be used for illegal activities, and your IP address will still belong to you.
Below is a table showing a comparison of the risks of different Wi-Fi module operating modes on devices. Redmi:
| Parameter | WPA2/WPA3 | Open Wi-Fi | WEP (obsolete) |
|---|---|---|---|
| Data encryption | High (AES) | Absent | Low (easy to hack) |
| Unauthorized access | Only with a password | Free | With a password |
| Risk of interception | Minimum | Critical | High |
| Recommended use | Daily | Temporary/Test | Do not use |
⚠️ Warning: If you are forced to use open mode to connect to specific equipment, limit the access point's operating time and do not conduct financial transactions during this period.
Connection problems and their solutions
Users Xiaomi Redmi Sometimes we encounter a situation where Open Wi-Fi settings get lost or the access point doesn't start. This is often due to power saving. The system MIUI aggressively limits background processes, considering the hotspot a drain on battery life. You must manually enable autostart for Wi-Fi system services.
Another common issue is frequency conflict. If the access point settings are set to 5 GHz, but the connecting device only supports 2.4 GHz, the connection will fail. See the section Open Wi-Fi Settings or simply try switching the frequency range to "2.4 GHz" in the access point settings for maximum compatibility.
It's also worth checking whether the "Traffic Limit" or "One-Time Access Point" features are enabled. These settings can automatically disable internet tethering after a certain amount of time or after one device is connected, which may be perceived by the user as a bug. Open Wi-Fi.
Speed and stability optimization
To ensure stable operation of the access point on Redmi It's important to select the correct broadcast channel. In a crowded apartment building, automatic channel selection may not work correctly. In the advanced settings (if available in your version) MIUI) try manually selecting channels 1, 6 or 11 for the 2.4 GHz band.
The network name (SSID) also plays a role. Using special characters or emojis in the access point name can cause connection issues on older devices or gadgets from other manufacturers. It is recommended to use standard Latin characters for the network name to ensure maximum compatibility protocols.
If your data transfer speed is low in hotspot mode, check if data saving mode is enabled. It can artificially reduce speeds or block downloads of heavy content for connected clients. Disable this feature in the "Data Usage" menu if performance is important to you.
