Smartphones of the line Galaxy S8 from the company SamsungDespite their age, these devices remain reliable and capable of performing multiple tasks, including serving as a mobile router. When wired internet is unavailable and a laptop or tablet urgently requires a network connection, knowing how to properly configure an access point becomes a critical skill for any user. This model supports modern communication standards, ensuring stable data transfer speeds for multiple devices simultaneously.
The process of activating modem mode in the shell One UI or earlier versions Samsung Experience may differ from standard Android, which often raises questions among owners. We'll cover not only the basic steps for enabling it, but also delve into the finer settings that will help optimize the connection and reduce battery consumption. Understanding these nuances will allow you to use your smartphone as efficiently as possible as an internet source.
Before we get started, it's worth noting that the quality of the connection directly depends on the cellular network signal strength and your carrier's data plan. Make sure your mobile data is enabled and you have sufficient data, as creating a wireless network is impossible without it. Below, we'll walk you through each setup step in detail to avoid any errors during device configuration.
Basic hotspot setup on the Samsung Galaxy S8
First, you need to access your device's main settings menu. This can be done in two ways: via the gear icon in the app drawer or via the quick settings panel by sliding the notification shade down from the top. For owners Samsung S8 It is more convenient to use the second method, as it allows you to quickly activate the necessary functions without unnecessary menu navigation.
Find the section, which, depending on the firmware version, may be called "Connections" or "Access Point & Modem." This is where all the tools for managing your phone's network interfaces are located. Tapping this section will reveal switches for Bluetooth modem, USB modem, and the mobile Wi-Fi hotspot itself.
Toggle the switch next to "Mobile Hotspot." The system may warn you that using this feature will increase data usage and battery life. Confirm, and your smartphone will begin broadcasting a wireless signal. By default, the network will be named "Galaxy S8" or something similar, and you'll need to enter a password to connect.
It is important to understand that when you first turn on the system, it automatically applies standard security settings, which, however, it is recommended to check. Encryption WPA2 PSK is the default, which is the optimal choice for most public and home use cases. Keep your network open to prevent unauthorized access to your traffic.
Advanced network configuration and security settings
To ensure your hotspot operates reliably and is protected from prying eyes, you need to access the hotspot's settings menu. To do this, tap "Mobile Hotspot" (not the switch, but the section name), then select "Settings" or "More," depending on your interface version. This opens up detailed configuration options.
The first thing you need to do is change the network name (SSID) to a unique one that will easily identify your device in the list of available connections on other devices. The default name often includes the phone model, which can be inconvenient if your friends also have devices. SamsungChanging the name does not affect speed, but makes it easier to identify.
Pay special attention to the "Password" field. It should be complex enough to resist brute-force attacks, but you should also be able to remember it or quickly look it up in the settings. The minimum password length is typically 8 characters, and the system won't allow you to set a password that's too simple.
⚠️ Note: If you change the password or network name, all previously connected devices will be disconnected and will require re-entering the new credentials for authorization. Warn users in advance if you share internet with colleagues.
This menu also contains the important "Show Device" option, which allows you to control the visibility of your network. Hiding the SSID requires manually entering the network name on the client device to connect, which adds a layer of security but reduces usability. This is rarely necessary for home use, but can be useful in crowded areas.

Managing connected devices and limits
One of the key features that is often overlooked by users is control over connected devices. In the access point menu Samsung S8 There's a "Connected Devices" section that displays all the gadgets consuming your data in real time. You can see the MAC addresses and names of connected clients, which helps identify "unwanted guests."
The system allows you to set the maximum number of connected devices. By default, this limit can be quite high, but to preserve speed and battery life, it's best to limit the number of clients. For example, if you only need to connect a laptop and a tablet, set the limit to two devices. This will prevent other phones from connecting if they somehow learn your password.
The Device Management feature allows you to manually block specific devices. If you notice a device with an unfamiliar MAC address, you can block its access without even changing the password. This is especially convenient when you need to quickly cut someone off from the network without disrupting the connection for everyone else.
What is MAC filtering?
This is a method of access control in computer networks based on unique network interface identifiers. On the Samsung S8, you can create a whitelist of approved devices, and even if you know the password, other devices will be unable to connect. However, for the average user, it's easier to use a strong password, as MAC addresses can be cloned if desired.
The sleep timer is also worth mentioning. In the settings, you can set the access point to automatically turn off if no one connects to it for a certain period of time (for example, 5 or 10 minutes). This is a useful power-saving feature that prevents the Wi-Fi module from running unnecessarily.
Choosing a Frequency Band: 2.4 GHz vs. 5 GHz
Flagship Samsung Galaxy S8 It has a significant advantage over budget models: it supports the 5 GHz band. In the access point settings menu (usually under "Advanced" or directly in the settings list), you can select the "Band" option. 2.4 GHz is often selected by default, as it offers better penetration and compatibility with older devices.
The 2.4 GHz band offers wider coverage, but it's heavily congested in apartment buildings, leading to interference and reduced speeds. If your connected devices (such as laptops and modern tablets) support 5 GHz, switching to this frequency will significantly improve connection speed and stability, especially in densely populated areas.
However, the 5 GHz band also has its drawbacks: it has a shorter range and is less effective at penetrating walls. If you plan to share internet with a device in another room or through one wall, it's better to stick with the 2.4 GHz frequency. The choice depends on your priorities: speed in the immediate area or coverage over a longer distance.
It's important to note that when switching to 5 GHz, some older devices may simply "not see" your network. This is normal behavior, as their network modules do not physically support this standard. In this case, you'll need to go back to the settings and select 2.4 GHz or use a dual-band router.
Comparison of distribution methods: Wi-Fi, USB, and Bluetooth
In addition to the classic air distribution, Samsung S8 offers alternative internet transfer methods that may be more efficient in certain scenarios. Below is a table comparing the key features of the three methods available on the device.
| Parameter | Wi-Fi hotspot | USB modem | Bluetooth modem |
|---|---|---|---|
| Transfer speed | High (up to 100+ Mbps) | Maximum (stable) | Low (up to 2-3 Mbps) |
| Battery consumption | High | Low (charging) | Average |
| Number of clients | Up to 10 devices | 1 device (PC) | 1-2 devices |
| Difficulty of setup | Minimum | Requires drivers/cable | Requires pairing |
A USB modem is ideal for sharing internet with a desktop computer or laptop nearby. This way, your phone not only transmits internet but also charges from the computer's port, eliminating the problem of battery drain. To activate, connect the cable and, in the "Access Point & Tethering" menu, toggle the "USB Modem" slider. This switch will only become active when a connection is established.
Bluetooth modem is rarely used due to its low speed, but it can be a lifesaver when the Wi-Fi module on the receiving device is faulty and the USB port is busy or unavailable. The speed is only sufficient for loading pages or messaging apps, but video playback is impossible. This requires pairing the devices through the Bluetooth menu before activating the modem.
⚠️ Attention: When using a USB modem on Windows computers, drivers may be required. Usually Samsung S8 is defined as a standard network device, but in rare cases (especially on Windows XP or older builds) it may be necessary to install Samsung USB Driver.
Optimization and solution
Sometimes users encounter a situation where the hotspot is enabled, but the internet on connected devices isn't working or is extremely slow. First, check if the mobile internet is working on your phone. Open a browser and try loading any page. If not, the problem is with your carrier or the APN settings.
The second common problem is overheating. When actively distributing Wi-Fi, especially in the 5 GHz band, and when the cellular network signal is poor, the processor and modem S8 may become very hot. The system may automatically reduce speed or disable the access point to protect components. Remove any case or case, if it has a thick one, and place the phone on a hard surface for better heat dissipation.
It's also worth checking your carrier's APN (Access Point Name) settings. Sometimes providers change parameters, and old settings no longer work correctly for tethering. You can reset your APN settings to factory defaults in the "Mobile Networks" menu -> "Access Point Names" -> "More" menu -> "Reset to Factory Defaults." Then, restart your phone.
Please remember that software and interfaces are subject to update. Telecom operators periodically change their data plan pricing, so it's always a good idea to check your mobile operator's personal account for up-to-date information.
Why does my Samsung S8 drain quickly when using Wi-Fi?
Hotspot mode forces two radio modules (4G/LTE reception and Wi-Fi transmission) to operate simultaneously, which puts a significant strain on the battery. Furthermore, the screen, if left on, consumes a lot of power. To extend battery life, enable power saving mode and reduce screen brightness.
Is it possible to share Wi-Fi if the phone is connected to a Wi-Fi network?
On standard firmware Samsung S8 You can't simultaneously receive and broadcast Wi-Fi (repeater mode). Your phone must use mobile data (3G/4G) to create a hotspot. However, there are third-party apps that require root access that can bypass this limitation, but their use is not guaranteed.
How do I hide my network name from others?
In the access point settings, find the "Hide my device" or "Hide SSID" option. Once enabled, the network will no longer appear in the general list. To connect, you'll need to manually enter the network name on the client device. This doesn't provide 100% protection, but it does hide the network from unauthorized users.
What should I do if my devices don't see my Samsung hotspot?
Try changing the frequency band from 5 GHz to 2.4 GHz in the hotspot settings. Also, check if there's a connection limit. In rare cases, resetting network settings in the phone's main settings menu may help (this will delete saved Wi-Fi passwords and Bluetooth settings).
