You have turned on access point on a smartphone, the laptop successfully connected to Wi-Fi, but the pages do not load, and there is an exclamation mark next to the network indicator? This problem is familiar to millions of users - and its reasons may lie in the phone settings, in the laptop settings, or even in the peculiarities of the mobile operator. In 80% of cases, the malfunction is fixed in 5–10 minutes if you know where to look.

In this article we will look at all possible scenarios: from trivial errors in settings APN to rare conflicts IPv6 and problems with DHCP server on the phone. You will learn how to diagnose the problem on Windows 10/11, macOS and even Linux, and also get checklists for quick testing. We will pay special attention hidden settings of Android and iOS, which operators often block “for security”, but which can disrupt the Internet distribution.

1. Checking basic settings: 3 steps before deep diagnostics

Before you dig into system settings, make sure the problem isn't something obvious. According to statistics Google Fi And Megafon, 35% of support calls on this topic are resolved at this stage.

First, reboot both devices: phone and laptop. This will reset temporary network caches and restart DHCP client. On Android for reliability, disable the access point, then enable flight mode for 10 seconds, then activate the distribution again. On iPhone just turn it off/on Modem mode in the settings.

  • 🔄 Reboot your phone: Hold the power button, select "Restart" (on iPhone — swipe the power off slider, then turn it on again).
  • 📶 Resetting the network on a laptop: in Windows run the command netsh winsock reset in CMD (on behalf of the administrator). On macOS remove the network connection in System Settings → Network and add again.
  • 📱 Checking mobile internet: Open a browser on your phone and try to load a website (for example, google.com). If it doesn’t load, the operator has a problem.

If after rebooting the laptop still cannot access the network, but remains connected to the access point, continue to the next section. Exception: if there is no Internet on your phone either, call the operator (technical work or blocking for debts is possible).

2. Access point settings on the phone: what could go wrong

Smartphones often reset Internet distribution settings after updates or when changing the SIM card. Let's look at the key points for Android And iOS.

For Android (Samsung, Xiaomi, Google Pixel, etc.)

Go to Settings → Connections → Hotspot and tethering → Mobile hotspot. Check here:

  • 🔐 Password: if it is too simple (for example, 12345678), some laptops block the connection as an “unsecure network”. Use a combination of 8+ characters with letters and numbers.
  • 📡 Frequency range: If the laptop is older than 2018, it may not support 5 GHz. Switch the access point to 2.4 GHz.
  • 🔄 APN profile: operators like Beeline or Tele2 sometimes require manual configuration. Check in Settings → Mobile network → Access Points (APN)that the correct profile is specified (for example, internet.beeline.ru).

For iPhone (iOS 15/16/17)

On iPhone the problem is often related to restrictions Low Data Mode or MAC Address Privacy. Open Settings → Modem mode and:

  • 🔒 Disable "Low Data Consumption" (if enabled).
  • 🔄 Reset network settings: Settings → General → Transfer or reset iPhone → Reset → Reset network settings.
  • 📱 Check "Maximum Compatibility": in the access point settings, enable the option Max. compatibility (if any).

If after the changes the laptop is still without the Internet, but there is a connection, go to the settings IP and DNS on the computer.

3. Diagnostics on a laptop: IP, DNS and hidden parameters

When a laptop connects to an access point, but there is no Internet, the culprit may be incorrect IP addresses, DNS failure or firewall blocking. Let's start by checking the network parameters.

Checking IP Address (Windows/macOS/Linux)

Open command prompt (Win + R → cmd on Windows or Terminal on macOS) and enter:

ipconfig /all

Look for a block with the name of your access point (for example, Wi-Fi Wireless LAN Adapter). Please note:

  • IPv4 address: must be in range 192.168.x.x or 10.0.x.x. If the address is like 169.254.x.x - this is DHCP error (the phone does not provide IP).
  • Main gateway: must match the phone's IP (usually 192.168.43.1 for Android or 172.20.10.x for iPhone).
  • DNS servers: if empty or incorrect addresses are specified (for example, from the previous network), the Internet will not work.

Manual IP and DNS configuration

If the IP address starts with 169.254, try assigning it manually:

  1. On Windows: Control Panel → Network and Internet → Network and Sharing Center → Change adapter settings. Right click on your Wi-Fi, select Properties → IP version 4 (TCP/IPv4).
  2. Check the box Use the following IP address and enter:
    • IP address: 192.168.43.100 (for Android) or 172.20.10.100 (for iPhone)
    • Subnet mask: 255.255.255.0
    • Main gateway: 192.168.43.1 (Android) or 172.20.10.1 (iPhone)
    • DNS servers: 8.8.8.8 And 8.8.4.4 (Google) or 1.1.1.1 (Cloudflare)

On macOS the path will be: System settings → Network → Wi-Fi → Advanced → TCP/IP. In the field IPv4 configuration select Manually and enter similar parameters.

💡

If, after manually setting up the IP, the Internet works, but the speed is low, return to automatically obtaining an address (DHCP) and check your phone settings - perhaps the problem is bandwidth limitation on the smartphone side.

4. Firewall and antivirus conflicts: who is blocking the connection

Guilty in 20% of cases Windows firewall or a third-party antivirus (for example, Kaspersky, Avast, ESET). These programs can block "suspicious" connections to mobile networks, especially if you have previously connected to public Wi-Fi.

Windows Firewall Check

Open Control Panel → Windows Firewall → Allow application interaction. Make sure that for your network (it may be called Public or Private) are allowed:

  • 🌐 Network discovery
  • 📤 File and Printer Sharing
  • 🔄 ICMP Echo Request (for ping)

If this does not help, temporarily disable the firewall completely and check the Internet. If it works, add an exception for your Wi-Fi connection.

Antiviruses and VPNs

Third-party antiviruses often have their own firewalls. For example, in Kaspersky need to go to Settings → Security → Firewall and:

  1. Add your access point to Trusted networks.
  2. Disable Monitoring network activity for the test.

Also check if it is enabled VPN on a laptop or phone. Some VPN services (eg. ProtonVPN or NordVPN) block local connections if there is no active subscription.

How to check if an antivirus is blocking a connection?

Open the task manager (Ctrl+Shift+Esc), find the antivirus process (for example, avp.exe for Kaspersky) and end it. If the Internet works, the problem is in the antivirus. Don't forget to turn the protection back on after the test!

5. Problems on the operator’s side: APN, restrictions and balance

Mobile operators sometimes make changes to settings APN or limit the distribution of the Internet (especially on unlimited tariffs). For example, MTS And Beeline can block tethering (distribution) for tariffs marked “only for smartphones”.

How to check APN

On Android:

  1. Go to Settings → Mobile network → Access Points (APN).
  2. Select the active profile and check the fields:
    • Name: usually internet or the name of the operator (for example, MTS INTERNET).
    • APN: for MTS — internet.mts.ru, for Beeline — internet.beeline.ru.
    • Authentication type: must be PAP or CHAP.
  • If the profile is missing, create a new one (the settings can be found on the operator’s website).

    • On iPhone APN is usually configured automatically, but if the distribution does not work, try:

    1. Go to Settings → Cellular → Data options → Cellular data network.
    2. Enter APN details manually (for example, for Tele2: internet.tele2.ru).
    3. Reboot your phone.

    Operator restrictions

    Some tariffs explicitly prohibit Internet distribution. For example:

    Operator Tariffs with restrictions How to get around
    MTS "Tariffishche", "Smart" Buy the "Modem" option or change the tariff
    Beeline "All for food", "Unlimited for everything" Send USSD request *110*181#
    Tele2 "My Tele2", "My Conversation" Connect to "Unlimited modem" for 50₽/day
    Yota All tariffs without the "Modem" option Activate the option in your personal account

    If you suspect a blockage, call the operator and check whether distribution is allowed on your tariff. Sometimes it is enough to send a USSD command (for example, for Megaphone: *105*00#).

    💡

    If after changing the APN the Internet started working, but after 5-10 minutes it disappeared again, the operator can use dynamic tethering blocking. In this case, only changing the tariff or using a VPN on your phone will help (for example, 1.1.1.1 Warp).

    6. Rare causes: from IPv6 to Wi-Fi drivers

    If all the previous steps did not help, the problem may be:

    • 🔌 IPv6 conflict: some operators (for example, Tinkoff Mobile) do not support IPv6 on access points.
    • 🖥️ Outdated Wi-Fi drivers: especially relevant for laptops Lenovo And HP 2015–2017.
    • 🔄 Double NAT: if the phone is connected to another Wi-Fi and simultaneously distributes the Internet.

    Disabling IPv6

    On Windows:

    1. Open Control Panel → Network and Internet → Network and Sharing Center → Change adapter settings.
    2. Right click on Wi-Fi → Properties → uncheck IP version 6 (TCP/IPv6).
    3. Restart your laptop.

    Updating Wi-Fi Drivers

    Outdated drivers can cause problems with DHCP or WPA3. Update them:

    1. Click Win + X → Device Manager.
    2. Expand Network adapters, find your Wi-Fi module (for example, Intel Wi-Fi 6 or Qualcomm Atheros).
    3. Right click → Update driver → Automatic search.

    If Windows does not find updates, download the driver from the laptop manufacturer's website (for example, support.lenovo.com for Lenovo).

    How to check double NAT?

    If the phone is connected to another Wi-Fi and distributes it, a routing conflict may occur. Turn off Wi-Fi on your phone and leave only mobile Internet for distribution.

    7. Alternative methods of Internet distribution

    If the access point still does not work, try alternative connection methods:

    • 🔌 USB modem: connect your phone to your laptop via cable and turn it on USB modem in the phone settings. This method bypasses Wi-Fi restrictions.
    • 📡 Bluetooth modem: Pair your devices via Bluetooth, then turn on your phone Modem via Bluetooth. The speed will be lower, but the stability will be higher.
    • 🌐 Reverse tethering: if the laptop has Internet (for example, via Ethernet), you can distribute it to the phone, and then back to the laptop via Wi-Fi (bypassing operator blocking).

    For USB modem on Android may need to be enabled USB Debugging (Settings → For Developers). On iPhone It is enough to trust the computer the first time you connect.

    If none of the methods work, the problem may be a hardware failure (for example, a broken Wi-Fi module in a phone or laptop). In this case, contact the service center.

    FAQ: Frequently asked questions about the problem

    🔍 Why does the laptop connect to the access point, but the pages do not load, but Skype/Telegram works?

    This is a typical sign of a problem with DNS servers. Applications like Skype or Telegram use direct IP connections and browsers rely on DNS. Try manually setting up DNS from Google (8.8.8.8) or Cloudflare (1.1.1.1) in the network adapter settings.

    📱 There is Internet on the phone, but when distributing it on the laptop it says “No Internet access.” What's the matter?

    Most likely the operator is blocking tethering (distribution) at your rate. Check the tariff conditions or call support. The problem may also be due to incorrect settings APN - compare them with the reference ones on the operator’s website.

    🖥️ After updating Windows, the laptop stopped connecting to the access point. How to fix it?

    Windows updates often reset network drivers. Try:

    1. Roll back Wi-Fi driver to Device Manager (right click on the adapter → Properties → Driver → Roll Back).
    2. Install the driver manually from the laptop manufacturer's website.
    3. Reset the TCP/IP stack with the command netsh int ip reset in CMD (on behalf of the administrator).
    🔄 The laptop connects to the access point, but after 1-2 minutes the Internet disappears. Why?

    This may be due to:

    • Battery saving on your phone (turn off hotspot optimization in battery settings).
    • Operator limitation (some plans break the connection after a certain amount of traffic).
    • IP conflict (try assigning a static IP on your laptop as described in section 3).
    🛡️ The antivirus is blocking the connection to the access point. What to do?

    Add your access point to antivirus exclusions:

    • B Kaspersky: Settings → Security → Firewall → Trusted networks.
    • B Avast: Settings → Security → Firewall → Application Rules.
    • B ESET: Settings → Network → Personal Firewall → Zones.

    If it doesn’t help, temporarily disable your antivirus for testing (don’t forget to turn it back on!).
