A more detailed path is as follows: go to Settings, select a section Connections, then press Mobile hotspot and tetheringHere you will see a switch Mobile hotspotBefore turning it on, it is recommended to click on the function name (not the switch) to set the network name and password.
☑️ Check before turning on the access point
Once activated, a corresponding indicator will appear at the top of the screen. Your laptop will now be able to detect your network in the list of available connections. The default network name usually includes your device model, for example, Samsung Galaxy S23, but it can easily be changed to something more understandable.
Configuring security and frequency range settings
To ensure maximum connection speed and security, you must properly configure the network settings you are creating. By default, Samsung uses the encryption standard WPA3-Personal or WPA2, which is a reliable protection against unauthorized access.
Particular attention should be paid to the selection of the frequency range. In the access point menu, find the item Setting up a Wi-Fi hotspot or AdditionallyThere will be an option there. RangeChoosing between 2.4 GHz and 5 GHz is critical for performance.
| Parameter | 2.4 GHz band | 5 GHz band |
|---|---|---|
| Speed | Below (up to 150-300 Mbps) | High (up to 800+ Mbps) |
| Range of action | Higher, penetrates walls better | Below, the signal fades faster |
| Workload | High (many neighboring networks) | Low (less interference) |
| Compatibility | Works with all devices | Only with modern adapters |
If your laptop supports the standard 802.11ac or ax (Wi-Fi 6), be sure to select the 5 GHz band. This will ensure minimal latency (ping) and fast download speeds. However, if your laptop is an older model and doesn't see the network after switching, reset the setting to 2.4 GHz.

Connecting a laptop to a smartphone's network
Once the hotspot on your phone is activated and configured, we move on to the laptop. The connection process is standard for any operating system, whether it's Windows 10/11 or macOSMake sure the Wi-Fi module on your computer is enabled.
Click the network icon in the system tray (lower-right corner in Windows) or the menu bar (in macOS). In the list of available networks, find the name you set on your smartphone. Click ConnectThe system will ask you to enter the security key.
Enter the password you set in your Samsung hotspot settings. Be careful: the password is case-sensitive. For easier entry on your phone, you can tap the "eye" icon in the password field to see the full password and rewrite it correctly.
- 💻 Select the network profile "Private" (for home) or "Public" (for safety in crowded places).
- 🔒 Make sure the connection status has changed to Connected, protected.
- 🌐 Check your internet connection by opening any website in your browser.
If the connection is successful, a notification indicating the number of connected devices (e.g., "1 device connected") will appear at the top of the smartphone screen. This confirms that the connection between the devices has been established correctly.
Solution: The laptop does not see the network or there is no Internet.
Despite the simplicity of the procedure, technical glitches sometimes occur. The most common issue is when the laptop detects the network and connects, but displays "No internet access." This is often due to configuration errors. APN (access points) of the mobile operator or a temporary DNS failure.
Try rebooting the communication module: turn it on on your phone Airplane mode for 10 seconds, then turn it off. Once the 4G/LTE signal is restored, reactivate the hotspot. On a laptop, use the built-in diagnostic tool: right-click the Wi-Fi icon → Diagnostics.
If your laptop doesn't detect the network at all, check the hidden settings. Some versions of One UI have an option Hide my device in the access point settings. If this is enabled, the network will not appear in the general list, and you will have to enter the network name (SSID) manually.
What to do if the connection speed is extremely slow?
Slow speed is often caused by a weak cellular signal. Try moving your phone closer to a window. Speed may also drop if system updates or photo syncing are downloading in the background. Disable background downloads on your phone.
Another cause is an IP address conflict. In rare cases, a static IP on a laptop can interfere with the connection. Make sure that in the protocol properties IPv4 It is worthwhile to automatically obtain an IP address and DNS servers.
Optimization of traffic and energy consumption
