Owners of mid- and high-end smartphones often face the need to provide other devices with access to the global network when a stationary router is unavailable. Samsung Galaxy A52 It's one of the most popular devices capable of acting as a full-fledged mobile hotspot thanks to its support for modern communication standards and dual-band Wi-Fi. Activating this feature on a device running One UI is intuitive, but it does come with a few caveats that affect connection speed and stability.
Using a smartphone as a access points This makes it a powerful tool for remote work or entertainment, but it requires careful configuration of security and power-saving settings. The wrong frequency band or a weak cellular network signal can negate all the benefits of a fast 4G or 5G connection. In this article, we'll cover every step of setup, optimization, and troubleshooting to ensure your Galaxy A52 acted as a secure network gateway.
Before diving into the technical details, it's worth noting that data quality directly depends on carrier coverage and battery life. Modern Android algorithms can aggressively limit background data transfers to save power, so it's important to configure the system correctly. We'll look at how to bypass typical limitations and maximize bandwidth.
Basic activation of tethering mode via the notification shade
The fastest way to start router mode on Samsung A52 — Use the Quick Settings panel, accessible by swiping down from the top. In the expanded menu, look for the icon labeled "Wi-Fi Hotspot" or "Mobile Hotspot." If the icon is hidden on the second page of the menu, tap the three vertical dots in the upper right corner and select "Edit" to drag the desired button to the home screen. Once tapped, the system will instantly create a secure network.
However, this method is not sufficient for initial setup, as the default settings may not meet your security requirements or compatibility with the devices you connect to. It is recommended to access the full settings menu at least once via Settings → Connections → Mobile hotspot & tetheringHere you can change the network name (SSID) to something more recognizable and set a strong password to prevent unauthorized access to your traffic.
It is important to understand that when an access point is activated, the phone automatically switches the radio module to high power mode. Interface The device may become slightly warm, which is normal when actively transferring large amounts of data. If you plan on a long session, it's best to remove the protective case to improve heat dissipation.
Setting up the 2.4 GHz and 5 GHz frequency bands
One of the key features Samsung Galaxy A52 Dual-band Wi-Fi support is a key feature, allowing you to choose between compatibility and speed. By default, the device operates in 2.4 GHz mode, which provides broad coverage but has limited throughput and is susceptible to interference from microwave ovens and neighboring routers. For modern devices, switching to 5 GHz.
To change this setting, go to the access point menu and tap "Settings." Under "Band," select 5.0 GHz. This will significantly increase data transfer speeds, which is critical for watching high-definition video or online gaming. However, keep in mind that older laptops or budget tablets may simply not detect the network in this range.
There's also a compromise option where the phone automatically selects the optimal frequency, but manual control often produces more predictable results. Experiment to determine which band works best in your location, taking into account the number of walls and the distance between devices.
⚠️ Note: Switching to 5 GHz may reduce the signal range, as high-frequency waves have difficulty penetrating solid objects. Keep your phone and receiving device within line of sight for best results.
Advanced security settings and access control
Security is a priority when using public wireless networks, and One UI offers flexible tools for controlling connections. In the access point settings menu, you can not only change the password but also select the encryption type. For maximum security, we recommend using the standard WPA3-Personal, if all your devices support it, as it provides the best cryptographic strength.
The "Allowed Devices" feature allows you to create a whitelist that only includes devices with known MAC addresses. This means that even if someone knows the password, they won't be able to connect to your network. To add a device, first connect it, then click the device name in the list of connected clients and select "Add to allowed."
It's also useful to set a limit on the number of devices that can be connected. By default Samsung A52 Allows you to connect up to 10 clients, but to save data and battery life, it's best to limit this number to 2-3. This will prevent a situation where someone "neighboring" you accidentally connects and starts downloading heavy files, hogging your bandwidth.

Comparison of connection methods: Wi-Fi, USB, and Bluetooth
Users often limit themselves to wireless methods alone, forgetting about wired alternatives that may be more effective in certain scenarios. Samsung Galaxy A52 Supports internet sharing via USB and Bluetooth, each with its own advantages and disadvantages. The choice of method depends on the type of device being connected and your goals.
Below is a comparison table to help you determine the optimal connection method in various operating conditions.
| Parameter | Wi-Fi Hotspot | USB Modem | Bluetooth PAN |
|---|---|---|---|
| Speed | High (up to 400+ Mbps) | Maximum (stable) | Low (up to 2-3 Mbps) |
| Energy consumption | High | Low (charging PC) | Average |
| Convenience | Wireless | Requires cable | Complex setup |
| Compatibility | All devices | PC, laptops, cars | Old gadgets |
USB tethering is especially useful when sharing internet with a desktop computer without Wi-Fi or when minimizing latency (ping) in games. Furthermore, when connected via a wired connection, the phone is simultaneously charged by the computer, eliminating the problem of rapid battery drain. To activate this mode, in the "Mobile Hotspot & Tethering" menu, toggle the "USB Tethering" slider to the on position after connecting the cable.
Why is Bluetooth modem still relevant?
Although Bluetooth speed is extremely low for the modern Internet, this method is sometimes the only possible way to connect specific industrial equipment or very old PDAs that do not support standard Wi-Fi security protocols.
Connection problems and their solutions
Despite the reliability Android, users may encounter a situation where devices cannot see the network or obtain an IP address. This is often caused by IP address conflicts or network service outages. The first step should always be to restart the access point: turn the toggle switch in the notification shade off and then on. If this doesn't help, try restarting the smartphone itself.
Another common issue is the "Obtaining IP Address" error on the device being connected. In this case, Samsung Galaxy A52 It's worth checking your DHCP settings. Go to the access point's advanced settings and try changing the Wi-Fi channel to a less crowded one (for example, 1, 6, or 11 for 2.4 GHz). Resetting the network settings also helps, but keep in mind that this will delete saved passwords for other Wi-Fi networks.
If your phone is connected to a 5G network but the internet connection is slow, check whether data saving mode or a background data limiter for system processes is enabled. Sometimes antivirus apps or firewalls can block incoming connections, deeming them suspicious.
⚠️ Please note: Carrier interfaces and plan terms are subject to change. If tethering isn't working, make sure your plan allows you to use your phone as a modem, as some carriers block this traffic or require a separate fee.
Optimizing power consumption when operating in router mode
The hotspot mode is one of the most energy-intensive modes for a smartphone, as the radio module simultaneously receives a cellular signal and transmits Wi-Fi. Samsung Galaxy A52 The device is equipped with an "Access Point Timer" feature, which automatically turns off the hotspot if no one is connected to the network for a set period of time (e.g., 10 minutes). This prevents the battery from draining completely if you forget to turn it off.
For maximum battery life, it's also recommended to reduce screen brightness or turn off the display completely, as it consumes a significant amount of power. In the battery settings, you can disable background activity of unnecessary apps to ensure all processor and network resources are dedicated to maintaining the internet connection. Using the dark interface theme also slightly reduces the load on the AMOLED screen.
If you're using a USB modem, the battery drain issue is resolved automatically, but when using Wi-Fi, it's a good idea to have a power bank handy. Modern algorithms One UI can limit processor performance when overheated, which indirectly affects the speed of processing network packets, so monitoring the case temperature is important.
Frequently Asked Questions (FAQ)
Why does my Samsung A52 laptop see the network, but it says "No Internet access"?
