It's a common situation where guests or colleagues need access to a wireless network but don't know or can't remember a strong password. Smartphone owners Xiaomi And Redmi People often look for a way to quickly and securely share internet access without manually typing characters. Modern technologies make this possible with just a few screen taps using built-in shell features. MIUI or HyperOS.
There are several proven methods that allow broadcast access Another device can connect to the network. You can use QR code generation, direct data transfer, or even set up a full-fledged access point if the router is located far away. Each of these methods has its own characteristics, advantages, and limitations, which you should be aware of for effective use.
In this article, we'll take a detailed look at all available options, explain the technical nuances, and answer frequently asked questions. You'll learn not only how to share passwords but also how to manage your personal network's security settings directly from your smartphone.
QR code method: the fastest way
The most elegant and modern solution is to use QR codesThis technology is built into the operating system. Android starting from version 10 and works great on devices RedmiThe method encodes all connection data (network name, encryption type, and password) into a graphic image that the other phone's camera can instantly read.
To use this method, you don't need to install any third-party apps. Simply unlock your smartphone while connected to the desired network and go to Settings. In the interface MIUI the path usually looks like this: Settings → Wi-FiClick on the name of the active network or the arrow next to it to see detailed information.
⚠️ Please note: The QR code screen displays the password in plain text beneath the image. Make sure there are no other people nearby who might detect the code before showing the screen to your guest.
After opening the network card, you'll see a square code. The guest needs to open the standard Camera app or the scanner in the Control Center and point the lens at your screen. The smartphone will automatically prompt you to connect to the network, and the user will only need to confirm the action. This eliminates errors when entering the code manually.
Setting up a Wi-Fi hotspot on Redmi
If direct password exchange is not possible or the router is out of range, the smartphone Redmi can act as a modem. Function Access point (Hotspot) allows you to broadcast mobile Internet or even rebroadcast a Wi-Fi signal (on some models with Wi-Fi Repeater support) to other devices.
To activate the mode, you need to go to the section Settings → Wi-Fi HotspotHere you can set the network name (SSID) and create a strong password. The system will prompt you to select a security standard, with the optimal choice being WPA2-Personal or WPA3, providing traffic encryption.
It's important to note that using hotspot mode significantly drains the battery. The phone's processor and radio module work under increased load, which can cause the casing to heat up. It's recommended to keep the device connected to a charger or in a well-ventilated area.
You can also limit the number of connected devices to prevent unauthorized access. The hotspot menu has a "Connected Devices" section where you can view a list of devices and block suspicious connections with one click.
Using the Share feature in MIUI
shell MIUI from Xiaomi offers its own data transfer ecosystem, which simplifies the exchange of not only files but also settings. The ShareMe feature allows you to transfer Wi-Fi settings between phones. Redmi And Xiaomi without the need to enter passwords or scan codes.
To use this method, both devices must be close to each other. On the source phone, select "Share" from the Wi-Fi menu, which will generate a temporary key. On the receiving device, use the file transfer menu or the built-in module. Mi Share data reception is initiated.
This method is especially convenient in offices or meetings attended only by users of this brand's equipment. Settings transfer speed is virtually instantaneous, and the data transfer protocol is protected by temporary session encryption.
Technical details of Mi Share
The protocol uses a combination of Bluetooth for device discovery and Wi-Fi Direct for data transfer. This allows for bypassing Bluetooth speed limitations and eliminates the need for a router to transmit parameters.
It's worth noting that for this feature to work correctly, Bluetooth and Wi-Fi must be enabled on both devices. If the transfer doesn't start, check that the receiving phone isn't in Stealth Mode or Power Saving Mode, which blocks background searches.
Comparison of access transfer methods
The optimal method depends on the specific situation, the guest's phone model, and your security preferences. Below is a comparison table to help you choose the best method for different use cases.
| Method | Connection speed | Security | Compatibility |
|---|---|---|---|
| QR code | High | Medium (password visible) | Android 10+, iOS 11+ |
| Access point | Average | High (WPA3) | Any device with Wi-Fi |
| Mi Share | Instant | High | Only Xiaomi/Redmi/Poco |
| Manual input | Low | High | All devices |
As can be seen from the table, QR code is a universal solution for mixed companies with both iPhone and Android devices. However, if you are in a device environment XiaomiThe built-in sharing feature will be faster. An access point is indispensable in areas where the main router's signal is unavailable.
When using any method, it's important to remember basic digital security hygiene. Don't leave password menus open for long periods of time, and regularly change your primary network access keys, especially if they've been used by unauthorized people.
Troubleshooting connection issues
Even automated methods can cause errors. Users often encounter a situation where the phone sees the network but fails to connect, or displays the message "Obtaining IP address." This may be due to the router's DHCP address pool being full.
In such cases, rebooting the Wi-Fi module helps. You need to go to Settings → Wi-Fi, turn off the slider, wait 5-10 seconds, and turn it back on. If this doesn't help, try selecting "Forget network" on the receiving device and reconnecting via QR code.
- 📶 Make sure the guest's phone isn't in airplane mode or power saving mode, which is blocking the network.
- 🔒 Check if your router has MAC address filtering enabled, which could block new devices.
- 🔄 If you're using the 5 GHz band, your old device may not see it. Switch your router to 2.4 GHz mode.
Another common issue is incompatibility of encryption protocols. If your router is configured to only operate in encryption mode, WPA3If the guest has an old smartphone, he may simply not see the network or be unable to log in.
⚠️ Note: MIUI and HyperOS interfaces may differ depending on the firmware version. If you don't find the described options, use the settings search by entering "Wi-Fi" or "Access Point."
Frequently Asked Questions (FAQ)
Is it possible to transfer Wi-Fi from Redmi to iPhone?
Yes, it's possible. The best way is to use a QR code. iPhones (iOS 11 and above) can read codes with their camera and automatically offer network connections. Mi Share doesn't work on iPhones.
Does Wi-Fi hotspot use a lot of data?
The sharing process itself (creating an access point) uses a minimal amount of data. However, all guest activity (watching videos, loading pages) will be handled through your mobile data or home network, which should be taken into account if you have any data limits.
Why does my phone say "Authentication Error"?
This means the password is incorrect or has changed. If you're granting access via QR code, make sure you're scanning the current code generated after the router's settings were last changed.
Is it safe to give guests access through a hotspot?
Using Guest Network mode on your router or creating a separate access point is more secure than sharing your main network where your personal files and smart home devices may be stored.
