Smartphone Not Sharing Wi-Fi: All the Reasons and How to Fix It

Are you trying to connect your laptop or tablet to the internet via your smartphone, but the hotspot stubbornly refuses to work? Is your smartphone not broadcasting Wi-Fi, even though everything was fine yesterday? This problem is familiar to millions of users, and the causes can range from simple settings to hardware issues.

In this article we will look at all possible reasonsWhy your smartphone stopped distributing internet via Wi-Fi - from errors in mobile network settings to operator restrictions. You will receive step-by-step instructions For Android And iOS, as well as tips for diagnosing the problem. It doesn't matter whether you're using Samsung Galaxy S23, iPhone 15 or budget Xiaomi Redmi — the solutions are universal.

Let's start with the most obvious and gradually move on to rare but critical cases. If you're in a hurry, take advantage of FAQ at the end of the article, where answers to the most frequently asked questions are collected.

1. Mobile Internet is disabled or not working

The most common reason why a smartphone doesn’t distribute Wi-Fi is lack of Internet itself on the device. The hotspot may be enabled, but without a mobile network connection, it's useless.

How to check:

• 📶 Make sure your smartphone has a network signal (icon 4G/5G or LTE in the status bar).
• 🌐 Try opening any website in your browser not via Wi-Fi (turn it off in settings).
• 💳 Check your account balance - you may have run out of money or have a tariff limit.

If the Internet does not work:

1. Restart your smartphone.
2. Turn on/off the mode On the plane for 10 seconds.
3. Check your APN (Access Point Name) settings in Settings → Mobile network → Access point names (APN)They must match your operator's parameters.

⚠️ Please note: APN settings may vary depending on your region and plan. If you recently changed your SIM card or plan, your settings may have reset. Check your operator's website for the latest information.

2. The access point is not turned on or is not working properly.

Even if you're sure you've enabled Wi-Fi hotspot, it's worth double-checking your settings. Sometimes your smartphone "forgets" saved settings or resets them after an update.

How to set up an access point on Android:

1. Go to Settings → Connections → Mobile hotspot & tethering (on Samsung) or Settings → Network & Internet → Hotspot & Tethering (on Xiaomi/Google Pixel).
2. Activate the switch Mobile hotspot.
3. Click Set up an access point and check:
   • 🔒 Network name (SSID) - must be unique (not AndroidAP or iPhone by default).
   • 🔑 Password — at least 8 characters, without Cyrillic.
   • 📶 Range — choose 2.4 GHz for better compatibility (if devices do not see the network on 5 GHz).

For iPhone:

1. Open Settings → Tethering.
2. Turn on Allow others.
3. Click Wi-Fi password and set a secure code (at least 8 characters).

3. Operator restrictions: blocking internet distribution

Many operators blocking internet distribution on some tariffs or after high-speed traffic has been exhausted. For example, MegaFon On the "Everything for Our Own" tariff, distribution can only work until 10 GB is used up, and Tele2 — requires option connection.

How to check:

• 📄 Log in to your operator's personal account or call support (*111# For MTS, *105# For Beeline).
• 🔍 Check if tethering is allowed on your plan. Sometimes it's only available after you activate a paid option (for example, "Modem" for Iotas).
• 📊 Check your remaining traffic — you may have reached your limit.

Operator	Tariffs with distribution blocking	How to unlock
MTS	"Tarifische", "XS"	Activate the "Modem" option (150 ₽/month)
Beeline	"It's Simple", "Unlimited"	Switch to the "Digital" tariff or add a "Mobile modem"
Megaphone	"Everything for our own"	After 10 GB the upload speed drops to 64 kbps
Tele2	"My Tele2", "My Conversation"	Activate the "Modem" option (free for subscribers older than 3 months)

⚠️ Note: Some carriers may block data sharing implicitly, for example, by limiting the speed to 128 kbps after the limit is reached. In this case, the smartphone will still share Wi-Fi, but the internet will be extremely slow.

4. Network settings issues: IP conflicts and DHCP

If your smartphone is distributing Wi-Fi, but the connected devices are not receiving the Internet, the problem may be in incorrect network settingsMost often it is:

• 🔢 IP address conflict - when two devices on the network have the same IP.
• 🔄 Disabled DHCP — the smartphone does not assign IP addresses automatically.
• 🛡️ Firewall or VPN - blocks data transmission.

How to fix:

1. On the connected device (laptop, tablet), run the command in Command line (Windows) or Terminal (macOS/Linux):

   ipconfig /release
   ipconfig /renew

   This will reset the current IP and request a new one from the smartphone.

2. On Android reset network settings:

   Settings → System → Reset → Reset Wi-Fi, mobile network, and Bluetooth settings

3. Turn off the VPN or firewall on your smartphone (in Settings → Network & Internet → VPN).

5. Hardware faults: Wi-Fi module or antenna

If the smartphone does not distribute Wi-Fi, but at the same time connects normally to other networks, the problem may be in hardware:

• 📡 Damaged Wi-Fi module (often after falls or exposure to moisture).
• 🔌 The antenna contact has come loose (typical for Samsung A-series And Xiaomi after disassembly).
• 🔋 Malfunction after firmware update (for example, on iPhone After iOS 17, some users complained about problems with distribution).

How to diagnose:

1. Try connecting to a different Wi-Fi network. If your smartphone can't see any networks, the problem is with the module.
2. Turn on Airplane mode, then only Wi-Fi. If the sharing works, a conflict with the mobile network is to blame.
3. Check if the top of your smartphone (where the Wi-Fi module is located) is getting hot. Overheating may indicate a malfunction.

⚠️ Caution: If your smartphone has been dropped or exposed to water, do not attempt to disassemble it yourself, as this may worsen the damage. Contact a service center.

What to do if your smartphone doesn't see any Wi-Fi networks?

This is a sign of a faulty Wi-Fi module. In 80% of cases, the only solution is to replace the module, which costs 3,000–8,000 rubles depending on the model. On iPhones, repair costs are higher due to the proprietary components.

6. Software failures: viruses, updates, application conflicts

Sometimes the reason lies in BY:

• 🦠 Viruses or malicious applications blocking distribution.
• 🔄 Conflict after firmware update (especially relevant for Android 14 And iOS 17).
• 📱 Apps for saving traffic (for example, Datally from Google) or VPNs that interfere with distribution.

How to fix:

1. Remove suspicious applications (check in Settings → Applications → Permissions, which programs request network access).
2. Reset network settings:
   • On Android: Settings → System → Reset → Reset network settings.
   • On iPhone: Settings → General → Transfer or reset → Reset network settings.

Update your firmware to the latest version or roll back if the problem appeared after the update.

On some Xiaomi smartphones (e.g., Redmi Note 10/11), a Wi-Fi hotspot issue occurs after updating to MIUI 14 due to a conflict with the "Dual Apps" feature. Disable this feature in your account settings.

7. Limitations on the number of connected devices

Many smartphones limit the number of devices that can connect to a hotspot. For example:

• 📱 iPhone — up to 5 devices simultaneously.
• 🤖 Android (depending on the model) - from 8 to 10 devices.
• 📶 Some operators (eg. Iota) artificially limit the number of connections to 1–2.

How to check and fix:

1. Open the list of connected devices in the access point settings. If there are too many, disable the unnecessary ones.
2. On Android You can increase the limit through the engineering menu (but it's risky!):

   ##4636## → Wi-Fi Information → Max. number of connected clients

   ⚠️ Warning: Changing settings in the engineering menu may result in unstable Wi-Fi performance. Only do this if you understand the risks.

3. Check your plan terms—your operator may be blocking data sharing across multiple devices.

8. Problems with connected devices

Sometimes the problem isn't with your smartphone, but with the device you're trying to connect. For example:

• 💻 The laptop or tablet "forgot" the network and cannot connect.
• 🔒 Incorrect password (case sensitive!).
• 📡 The device does not support the selected Wi-Fi band (for example, older laptops do not work on 5 GHz).

How to fix:

1. On the connected device Forget the network and reconnect:
   • On Windows: Settings → Network & Internet → Wi-Fi → Manage known networks → Forget.
   • On macOS: System Preferences → Network → Wi-Fi → Advanced → Remove Network.

Check if your device supports it WPA3 (If your smartphone uses this standard for network distribution, older devices may not be able to connect). Switch to WPA2 in the access point settings.

Try connecting from another device. If it connects normally, the problem is with the original device.

FAQ: Frequently asked questions about sharing Wi-Fi from your smartphone

❓ Why does my smartphone share Wi-Fi, but the internet doesn't work?

This is a typical situation where the access point is active, but traffic is not passing. Reasons:

• 📵 Mobile Internet is disabled on your smartphone (check the icon 4G/5G).
• 🔌 The operator blocks the distribution (see section 3).
