In today's digital world, situations often arise where you urgently need to provide internet access to a friend's laptop or tablet, but the mobile router is left at home. Smartphone owners Samsung And Xiaomi (Redmi, Poco) often encounter interface quirks in One UI and MIUI (HyperOS) that can be confusing when trying to set up internet sharing. Understanding How to share Wi-Fi from a Samsung to a Redmi, will allow you to quickly create a local network and provide a stable connection for all devices around.
Creating a hotspot doesn't require any special knowledge or third-party software, as this feature is built into the Android operating system. However, there are differences in menu layout and security settings between manufacturers' operating systems. In this article, we'll detail the steps that will help transform your phone. Samsung into a full-fledged router, and the device Redmi - to a client receiving a stable signal.
It's worth noting that connection quality directly depends on the frequency range settings and security standard. Incorrect configuration This can cause your Redmi to simply not detect the network or to constantly lose connection. We'll cover the nuances that are often overlooked by users but are critical for stable operation.
Preparing your Samsung for tethering
Before looking for a connection method, you need to properly configure the signal source. Smartphones Samsung With One UI, you can configure your hotspot settings in a menu deep within the app. The first step should always be checking your data plan, as carriers may limit speeds or data usage when using your phone as a router.
To begin activation, go to your device's main settings. You'll need to find the section responsible for network connections. The path may vary slightly depending on your Android version, but the process is the same for all Galaxy models.
In the menu that opens, select the item Connections, and then go to the section Mobile hotspot and modemThis is where the switch that initiates the hotspot sharing process is located. However, before turning it on, it's recommended to tap the "Mobile Hotspot" label (not the toggle switch) to access the advanced settings.
It's important to set a strong password right away to prevent unauthorized access to your traffic. Standard security settings usually offer a protocol WPA2 PSK, which is the optimal balance between compatibility and data protection.
⚠️ Note: Some carriers automatically detect your phone's data transfer mode (TTL) and may block the connection or charge additional fees. Check your plan's terms in your carrier's app before using TTL.
In this menu, you can also change the network name (SSID) so your phone can be easily found in the list of available networks on your Redmi. Avoid using standard names like "Galaxy S21"; instead, create a unique name that immediately identifies the owner.
Frequency range adjustment and compatibility
One of the key factors affecting speed and stability is the choice of broadcast frequency. Smartphones Samsung allow you to switch between the 2.4 GHz and 5 GHz bands. This is a critical parameter, since older models Redmi may not support the high-speed 5GHz band.
If you enable the 5 GHz band on your Samsung, and your Redmi is a budget model from previous years, it simply won't detect the network. Meanwhile, the 2.4 GHz band provides better signal penetration, but is slower and more congested with neighboring routers.
To set up, go to the access point menu on your Samsung, press More or Additionally, and then select Set up an access point. Find the item at the bottom of the screen. RangeHere you can select your preferred frequency or leave it on "Auto," which is recommended for maximum compatibility.
If you know that both devices support the standard Wi-Fi 5 (802.11ac) or newer, forcing 5 GHz will provide a significant speed boost. However, for universal compatibility, it's best to leave the default settings.
You can also set a timer to turn off the hotspot in this section. This is a useful battery-saving feature that automatically turns off the Wi-Fi module if no one connects to the network for a long time.
How to connect Redmi to Samsung network
Once the signal source is prepared, you need to connect from the device Xiaomi (Redmi, Poco). MIUI and HyperOS interfaces each have their own unique way of displaying the network list, but the basic algorithm remains standard for Android.
Unlock your Redmi and swipe down to open the notification shade. Long-press the Wi-Fi icon to quickly access the settings menu. Make sure the slider is active and blue or green.
In the list of available networks, find the name (SSID) you set on your Samsung. If you haven't changed the name, it will contain the phone model, for example, "Galaxy A50." Tap the network name.
The system will prompt you for a password. Enter the character combination you previously set on your Samsung. Please pay attention to the letter case and keyboard layout, as passwords are sensitive to these settings.
☑️ Connection checklist
After successful authorization, the "Connected" status will appear under the network name, and the Wi-Fi icon will appear in the status bar. If the system requests permission to access geolocation or share data, confirm this action, as this is necessary for network protocols to function.
Troubleshooting connection and visibility issues
Connections aren't always established on the first try. Users often encounter situations where Redmi sees the network but can't connect to it, or the network isn't listed at all. The main cause of these issues is security protocols and IP settings.
If your Redmi displays "Obtaining IP address..." and then disconnects, the issue may be an address conflict. Try changing the security protocol from WPA3 to WPA3 in the access point settings on your Samsung device. WPA2 PersonalNew encryption standards sometimes don't work correctly with older Wi-Fi module drivers.
Another common issue is hiding the SSID. If the "Hide my device" option is enabled on a Samsung device, the network won't appear in the general list. On a Redmi, you'll have to select "Add network" and manually enter the name and password.
| Problem | Possible cause | Solution |
|---|---|---|
| Redmi doesn't see the network | Incorrect range (5 GHz) | Switch Samsung to 2.4 GHz |
| Authentication error | Incorrect password or encryption type | Change the password, select WPA2 |
| No internet access | No mobile data on Samsung | Check balance and coverage |
| Low speed | 2.4 GHz channel congestion | Try 5 GHz or change the channel |
It's also worth checking whether background data transfer for system services is restricted on your Redmi, although this is rare. Restarting the Wi-Fi modules on both devices often helps clear temporary stack errors.
⚠️ Note: The One UI and MIUI interfaces are updated regularly. The layout of menu items may change. If you can't find the item you're looking for, use the settings search (the magnifying glass in the corner of the screen) and enter the keyword "Spot" or "Hotspot."
Using a QR code for quick authorization
Modern versions of Android, including those on Samsung And Redmi, support quick connection via QR codes. This eliminates the need to manually enter complex passwords and minimizes the risk of error.
On a Samsung device with a hotspot already enabled, tap the settings gear next to the hotspot switch. In the menu that opens, find the button QR code (usually located at the bottom or in the "More" menu). A graphic code will appear on the screen.
On your Redmi device, open the default Camera app or the scanner in the notification shade. Point the camera at the Samsung QR code. The system will automatically detect your connection type and prompt you to connect.
QR code security
The QR code contains your network password in clear text. Don't take screenshots of this code or send them via messaging apps. Anyone who scans this code will be able to connect to your internet without your knowledge.
This method is especially convenient if the password contains many special characters. It's also faster than manual entry, which is important in situations where internet access is urgent.
Optimizing battery and traffic consumption
Hotspot mode is one of the most energy-consuming processes in a smartphone. The Wi-Fi module operates in constant data transfer mode, which leads to rapid heating of the case and drains the battery. Samsung.
To extend the device's battery life, it's recommended to reduce screen brightness or turn it off completely after connecting the Redmi. You can also disable background syncing of heavy apps on the share phone itself.
Traffic control is another important aspect. You can set a data limit in the Samsung hotspot settings. Once the specified amount is used up, sharing will automatically stop, saving you from unexpected charges.
Monitor your device's temperature. If your Samsung phone starts to get noticeably hot, take a break from using it or remove the protective case to improve heat dissipation. Overheating can lead to throttling (decreased performance) and an unstable signal.
Alternative ways to distribute Internet
If a classic Wi-Fi access point for some reason does not work or does not satisfy you in terms of speed, there are alternative methods of transmitting the Internet with Samsung on Redmi.
The first option is - USB modemThis method requires physically connecting the phones with a cable. You'll need a USB-C to USB-C cable. Connect the Samsung to the Redmi, and select "USB tethering" in the Samsung's USB menu. The Redmi will receive internet via the cable, ensuring maximum stability and simultaneously charging the devices.
The second option is - Bluetooth modemThe speed will be significantly lower here, suitable only for messaging or navigation, but battery drain is minimal. Pair the devices via Bluetooth, then enable "Internet access" in the Bluetooth settings on your Samsung.
The third option is to create a group in the application Google Home or using the Nearby Share feature, although the latter is for file transfers rather than sharing a real-time connection.
Each method has its pros and cons. Wi-Fi is versatile and wireless, USB is reliable and fast, and Bluetooth is energy-efficient. The choice depends on your current needs and the cables you have on hand.
