How to Create a Wi-Fi Network on a Samsung Phone: A Complete Guide with Pictures and Tips

Modern smartphones Samsung Galaxy can replace a full-fledged router - just activate the function mobile hotspotThis is convenient when traveling, at the dacha, or when the main Wi-Fi suddenly goes down. However, many users encounter problems: devices don't connect, speeds drop, and the battery drains within an hour. In this article, we'll look into these issues. All the ways to create a Wi-Fi network on a Samsung device — from basic setup to solving hidden errors.

We tested the instructions on models Galaxy S23 Ultra, A54 And Z Flip5 with firmware One UI 6.1, but the algorithm is also suitable for older devices (starting from Galaxy S8). We will pay special attention to hidden power-saving settings that block internet access on 50% of smartphonesYou will also learn how to bypass operator traffic restrictions and why 5 GHz- the network works faster, but does not connect to all gadgets.

1. Preparing your phone: checking compatibility and tariff

Before turning on the access point, make sure that your Samsung supports this feature. On all models with Android 8.0+ And One UI 2.0+ Wi-Fi distribution works out of the box, but there are some nuances:

• 📱 Old models (Galaxy J3 2016, Grand Prime): options may be missing 5 GHz And WPA3.
• 📶 Operators (MTS, Beeline, Tele2): some tariffs block Internet distribution or limit the speed to 64 kbps.
• 🔋 Battery charge: When using a hotspot, your phone's battery drains 30-50% faster. Plug it in for extended use.

To check operator restrictions, send a USSD request:

*100#

Or call support to check if it is allowed. modem data transmission (sometimes called "tethering"). If the feature is blocked, you can bypass the restriction by VPN or tariff change.

⚠️ Attention: On phones with dual-SIM (two SIM cards) the hotspot can only work through the primary SIM card. Check the settings in Mobile Networks → SIM Cards.

2. Step-by-step instructions: how to enable the access point

The fastest way to share Wi-Fi is through the notification panel. But for fine-tuning (changing the password, choosing a band 2.4/5 GHz) you'll have to go to the menu. Follow the algorithm:

1. Open Settings (gear on the main screen).
2. Go to the section Connections → Mobile Hotspot & Tethering.
3. Tap on Mobile hotspot.
4. Activate the slider in the top corner.

By default the network will be called Samsung_XXXX (where XXXX are the last digits of the IMEI), and the password will be generated automatically. You can copy it by clicking the 📋 icon next to the field.

Make sure mobile internet is enabled

Write down or copy the network password

Disable your VPN (it may be blocking the distribution)

Check the battery charge (at least 20%)

-->

If you need to change the network name or password:

5. In the same menu, click Tune (or Access point configuration on older models).
6. In the field Network name (SSID) Enter the desired name (for example, MySamsungHotspot).
7. IN Security type select WPA2 PSK (the most reliable option for most devices).
8. Create a password of length at least 8 characters (use numbers, letters and symbols like ! or #).
9. Save the changes by clicking the button Ready.

⚠️ Warning: Do not use ( in the network name)SSID) Cyrillic or emoji - some devices (for example, MacBook or printers) will not be able to connect to it.

3. Selecting optimal settings: 2.4 vs. 5 GHz, WPA2 vs. WPA3

By default Samsung creates a network in the range 2.4 GHz, but on new models (Galaxy S22+ (and newer) there's a choice available. Let's figure out which option is best:

How to change the range:

1. Go to Settings → Connections → Mobile Hotspot.
2. Click Additionally (or More on older models).
3. Select Range and mark 5 GHz (if available).

For maximum security, please select WPA3 in the security settings, but keep in mind that some devices (for example, HP printers or Xiaomi smart light bulbs) do not support this protocol. In this case, leave WPA2/WPA3 (hybrid mode).

4. Troubleshooting: Devices won't connect or the internet isn't working

The most common mistakes when distributing Wi-Fi with Samsung and ways to fix them:

• 🔌 Connected, no internet access: Check if mobile internet is enabled on your phone. Sometimes rebooting or changing the APN type (in Settings → Mobile networks → Access points).
• 🔒 "Incorrect password" when entered correctly: reset the access point settings (in the menu Mobile Hotspot → Reset Settings) and set the password again.
• 📵 The network is not visible on other devices: Turn off power saving mode (Settings → Device Maintenance → Battery → Power Saving Mode).
• 🐢 Slow speed: if you have 4G-tariff, but the speed is the same 3G, check your APN settings or contact your operator.

If the problem persists, try alternative distribution methods:

• 🔗 USB modem: connect your phone to PC via cable and activate USB modem in the access point settings.
• 📡 Bluetooth modem: Suitable for devices without Wi-Fi (eg. laptops with a broken adapter).

What should I do if the operator blocks the distribution?

Some operators (for example, Tele2 on the "My Conversation" plan) restrict tethering. You can bypass the blocking as follows:

1. Install a VPN application (for example, ProtonVPN or Windscribe).

2. Connect to a server in another country.

3. Turn on the access point - the traffic will go through the VPN, and the operator will not be able to block it.

⚠️ Cons: Speed ​​may drop by 20–30% due to encryption.

5. Saving battery life during long-term distribution

Sharing Wi-Fi is one of the most energy-consuming functions of a smartphone. Galaxy S23 Ultra with an active access point the battery drains at a rate 1% per minute (with the screen at full brightness). To extend battery life:

• 🔋 Connect the charger: even a weak current (5W) will slow down the discharge.
• 🌑 Reduce screen brightness up to 30% and activate the dark theme.
• 📴 Disable unnecessary modules: NFC, GPS, the second SIM card (if any).
• ⚡ Use the "Optimized Performance" mode (Settings → Battery → Power mode).

On phones with One UI 5.0+ there is a hidden option Adaptive battery, which automatically limits background processes when sharing Wi-Fi. To enable it:

1. Open Settings → Device Maintenance → Battery.
2. Tap ⋮ (three dots) in the top corner.
3. Select More → Adaptive Battery.
4. Activate the slider.

6. Security: How to protect your access point from hacking

An open Wi-Fi network on your phone is an easy target for hackers. They can:

• 🕵️ Intercept your traffic (passwords, messages).
• 💰 Use your internet for illegal activities (torrents, DDoS attacks).
• 📱 Connect to your phone through protocol vulnerabilities WPS.

To protect yourself:

1. Always use a password (even if you distribute it temporarily).
2. Turn off the access pointwhen it is not needed.
3. Change your password every 2-3 days with long-term use.
4. Turn it off WPS in the router settings (if the phone is connected to the home network).

For maximum protection:

• 🔐 Use the password from 12+ characters with mixed case (for example, Samsung!WiFi_2026).
• 🔄 Turn on WPA3 (if supported by connected devices).
• 📵 Turn off Wi-Fi Direct And Smart Network Switch in the Wi-Fi settings.

⚠️ Warning: Never share Wi-Fi in public places (airports, cafes) without a VPN. Attackers can create a fake network with your phone's name and intercept your data.

7. Hidden Features: How to Boost the Signal and Increase the Number of Connected Devices

By default Samsung limits the number of connected gadgets to 8–10, but this value can be increased. There are also ways to improve signal stability:

To increase the limit of connected devices:

1. Open the app Telephone and dial *#0011#.
2. In the menu that opens, select Service Mode.
3. Go to [1] UMTS → [1] Debug Screen → [6] PHY → [1] NAS.
4. Find the parameter Max Wi-Fi Clients and change the value from 8 on 15.
5. Save the changes and restart your phone.

This method does not work on all firmware, but on Galaxy S22/S23 With One UI 5.1+ personally verified. If the item Max Wi-Fi Clients No, it means your model does not support the extension.

8. Alternative ways to distribute the Internet without Wi-Fi

If Wi-Fi isn't working or needs to be turned off (for example, on a plane), you can share the Internet in other ways:

• 🔌 USB modem: Suitable for PCs and laptops. It offers faster speeds than Wi-Fi and drains the battery more quickly.
  1. Connect your phone to your computer via cable.
  2. In the access point settings, select USB modem.
  3. A new network connection will appear on your PC.

📡 Bluetooth modem: slower (~3 Mbps), but more energy efficient. Suitable for smartwatches or older laptops without Wi-Fi.

1. Turn on Bluetooth on both devices.
2. Pair them (enter the same PIN).
3. In the access point settings, select Bluetooth modem.

Comparison of methods:

⚠️ Attention: On some models (Galaxy A13, M33The USB modem only works with an original Samsung cable. Cheap Chinese cables may not transfer data.
