Modern smartphones have long ceased to be just devices for making calls, having turned into full-fledged control centers for the digital world. Model Samsung Galaxy A52 It has a powerful modem that allows you to not only receive high-speed internet but also reliably transmit it to other devices. This feature, known as mobile hotspot, becomes a lifesaver when traveling, on business trips, or in situations when your home provider suddenly cuts off the power.
The process of activating the modem mode on devices of the brand Samsung While the One UI interface has been simplified to the extreme, many users are unaware of the hidden settings that affect connection speed and security. In this article, we'll cover all aspects of setup in detail, from basic activation to fine-tuning frequency bands.
You don't need to be a tech expert to turn your phone into a router. Simply follow the logical steps below to provide internet access to your roommate's laptop, tablet, or TV.
Basic access point setup via smartphone menu
The easiest way to enable tethering is to use the notification shade. Swipe down from the top of the screen twice to reveal the full list of quick buttons. Look for the icon labeled Access point and modem or simply Access pointClick on it and the phone will start broadcasting the signal.
However, for the initial setup, you need to go into the deep system menu. Follow the path Settings → Connections → Mobile hotspot & tetheringThis opens the control panel, where you can set the network name (SSID) and password. By default, the system generates a random name, but it's best to change it to something recognizable.
Pay attention to the password field. The standard length is usually 8 characters, but for security, it's recommended to use more complex combinations. The system will warn you if the password is too simple.
⚠️ Note: When you change your password, all previously connected devices will lose connection and require new authorization information. Please notify users in advance if you are changing settings in a public place.
The function is also available in this menu. QR code, located at the bottom of the screen. By scanning it with another smartphone's camera, a guest can connect to your network without manually entering characters. This is convenient and secure, as the password is not spoken aloud.
Setting up the 2.4 GHz and 5 GHz frequency bands
One of the key features of the model Samsung A52 is dual-band Wi-Fi support. In the access point menu, in the section Access Point Settings → AP Range, the user can choose between 2.4 GHz and 5 GHz frequencies. This is a critical parameter affecting range and speed.
Range 2.4 GHz It has greater penetration power. The signal penetrates walls better and is reliably received at a distance, but the data transfer rate is lower, and the airwaves are often clogged with signals from neighboring routers and Bluetooth devices.
Range 5 GHz Provides maximum speeds close to a wired connection and is less susceptible to interference. However, its range is significantly shorter and it's less able to penetrate obstacles. If you're sharing internet with a laptop placed next to your phone, choose 5 GHz.
What is the difference between 802.11 a/b/g/n/ac?
The 802.11ac (Wi-Fi 5) standard operates only at the 5 GHz frequency and delivers speeds of up to several Gbps. The b/g/n standards can operate at 2.4 GHz. The Samsung A52 supports modern protocols, delivering high speeds in the 5 GHz band.
Switching between bands is instantaneous, but requires clients to reconnect. If you notice video lagging on a connected device, try changing the frequency in your phone's settings.
Managing connected devices and limits
You can control who uses your traffic in the section Connected devicesThis displays a list of all devices online, along with their IP addresses and the amount of data transferred. You can see in real time exactly who's hogging your data plan.
A blocking function is available for each device. By clicking on a client's name, you can block their network access. This is useful if you've shared your password with friends, but someone starts downloading large files, slowing down the entire system.
- 📱 Maximum number of devices: by default The Samsung A52 allows you to connect up to 10 clients simultaneously, but this number can be reduced to save battery power.
- 📉 Traffic limit: In the settings, you can set a data limit (for example, 1 GB), after which the access point will automatically turn off.
- ⏳ Sleep timer: function
Disconnect if no connectionsAllows you to save battery by turning off the Wi-Fi module if no one has connected to the phone for 1, 3, 5 or 10 minutes.
⚠️ Note: The data limit is reset only when the hotspot feature is completely disabled or the phone is rebooted. The counter continues to increase during the same operation.
Using your data limits is especially important if you have a paid mobile data plan. A neighbor's accidental connection could result in unexpected charges or the plan being exhausted before the end of the month.

Hiding your network and increasing security
For privacy-conscious users, Samsung A52 You can hide your access point. In this mode, your network name (SSID) is not broadcast, and other devices won't see it in their list of available connections.
To connect to a hidden network, the user of the client device must manually enter the network name and encryption type (usually WPA2-Personal), as well as the password. This creates an additional barrier to unauthorized "neighbors" scanning the airwaves.
However, it's important to understand that hiding the SSID isn't a complete defense against hackers. Specialized software can easily detect hidden networks based on their responses to requests. Therefore, hiding the SSID should remain the primary method of protection. complex password and the WPA3 encryption protocol, if the connecting device supports it.
| Security parameter | Description | Recommendation |
|---|---|---|
| Password | Network access key | Minimum 12 characters, letters and numbers |
| Encryption | Data Protection Protocol | WPA2/WPA3 Personal |
| Hiding the SSID | Network invisibility | Use in crowded places |
| MAC filter | Access by address | For advanced users |
Changing your password regularly is a good habit, especially if you frequently use public hotspots. Avoid using birthdays or simple number sequences.
Sharing the Internet via USB and Bluetooth
If your phone's battery drains quickly or the Wi-Fi module is unstable, you can use a wired connection. Mode USB modem Allows you to stream internet to your computer via cable while simultaneously charging your smartphone.
To activate, connect your phone to your PC using a cable. In the menu Mobile hotspot and modem the switch will become active USB modemThe computer will recognize the phone as a network device, and the Internet will appear automatically after installing the drivers (usually happens automatically in Windows 10/11).
A Bluetooth modem is a slower option, suitable for transferring small amounts of text or email. It consumes less power than Wi-Fi, but connection speeds rarely exceed 1-2 Mbps. It's activated in the same way through the connections menu.
Power consumption and heating of the device
Hotspot mode is one of the most resource-intensive processes for a smartphone. The radio module operates at increased power, which leads to active heating of the case. Samsung A52 and rapid battery discharge.
When used as a router for extended periods, the phone may become noticeably warm, especially when using the 5 GHz band and connecting multiple active clients. In hot weather or direct sunlight, this may lead to throttling (reduced performance) or a crash.
- 🔋 Reduce brightness: Reduce your screen brightness or turn it off completely to reduce the overall heat load.
- ❄️ Cooling: Remove the protective case if it is thick and place the phone on a cool surface.
- 🔌 Nutrition: When using the phone for a long time, it is recommended to keep it connected to the charger, but keep an eye on the temperature.
⚠️ Caution: If your phone reports overheating and disables the hotspot, allow it to cool down while turned off. Continuing to use it in this condition may shorten the battery life.
System One UI The phone has built-in protection mechanisms that limit functionality when exposed to extreme temperatures. Do not attempt to circumvent these limitations by artificially cooling it (for example, by placing the phone in the freezer), as condensation can damage the electronics.
Common problems and solutions
Sometimes users encounter a situation where the hotspot is enabled, but the internet isn't working or devices can't see the network. Most often, the problem lies in the mobile network settings or a software glitch.
The first thing to check is whether your phone has mobile internet. Open your browser and make sure websites load without Wi-Fi. Also, check your balance and whether your carrier is blocking your data.
If you have mobile internet but tethering isn't working, try resetting your network settings. Go to Settings → General Settings → Reset → Reset Network SettingsThis action will delete saved Wi-Fi passwords and Bluetooth settings, but often solves problems with communication modules.
Why does the laptop see the network but not connect?
A common cause is incompatible security protocols or a full DHCP table on the phone. Try forgetting the network on your laptop, turning the hotspot on your phone off and on, and then reconnecting. Changing the Wi-Fi channel in the advanced settings also helps.
How to share Wi-Fi if you have a SIM card from a different operator?
Some carriers block or charge separately for tethering. If your phone has internet access but pages don't load via a hotspot, your carrier may be detecting the TTL of packets. In such cases, you may need to change the TTL on the connected device or use special apps, although this may violate your carrier agreement.
Why does the battery drain quickly when the hotspot is turned on?
In access point mode, the Wi-Fi module operates continuously and at high power, drawing significant current. This is normal behavior. For extended use, it's best to keep the phone charged and reduce screen brightness.
In conclusion, Samsung A52 is an excellent tool for organizing mobile internet. Properly configuring security parameters and frequency ranges will allow you to use this functionality most effectively and safely in any conditions.
