1. Checking the basic personal hotspot settings on your iPhone

Before you dig deeper, make sure that the modem mode is enabled correctlyEven experienced users sometimes miss obvious points. Open on iPhone Settings → Tethering and check:

  • 🔄 Modem mode is enabled (slider in the "On" position). On some models (for example, iPhone 12 With iOS 16+) confirmation may be required via Face ID or Touch ID.
  • 📶 Wi-Fi and Bluetooth are activeWithout them, the access point will not broadcast, even if the modem mode is enabled.
  • 🔒 Wi-Fi password does not contain Cyrillic characters or spaces. iOS automatically generates a complex password, but it can be changed manually (click Wi-Fi password).

If the modem mode slider gray and inactive, the problem may be with your mobile operator's tariff. Many Russian operators (for example, MTS, Beeline, Tele2) by default block internet tethering on unlimited data plans. To unblock this feature, send a USSD request: 

*111*77#

or contact support. On some plans, internet tethering may be charged separately—up to 50 rubles per day.

⚠️ Attention: If you use eSIM, make sure that the modem mode is enabled for the primary SIM card. iPhone With two physical slots, priority is given to the first SIM card.

Also check if it is turned on low power mode (Settings → Battery). When this option is activated iOS Automatically turns off Wi-Fi distribution to save battery power.

2. Connection problems on the computer side

If iPhone broadcasts the network correctly, but the computer does not connect or keeps disconnecting, the network adapter settings are to blame. Let's look at solutions for Windows And macOS separately.

For Windows 10/11:

  1. Open Settings → Network and Internet → Wi-Fi.
  2. Find the network from iPhone (usually the name matches the name of the device, for example, iPhone (Vasily)).
  3. Click Connect and enter the password. If an error appears "Unable to connect to this network", right-click on the network → Forget, then try connecting again.

If the connection is established, but the Internet does not work:

  • 🖥️ Check your settings IP addresses. Open Control Panel → Network and Sharing Center → Change adapter settings, find Wireless network, right-click → Properties → Internet Protocol Version 4 (TCP/IPv4). Make sure the boxes are checked. Obtain an IP address automatically And Obtain DNS server address automatically.
  • 🔄 Reboot network adapter. IN Device Manager find the section Network adapters, right click on Wi-Fi adapter → Disconnect the device, then turn it on again.

For macOS (Ventura/Monterey/Sonoma):

On MacBook or iMac problems connecting to iPhone are less common, but still possible. Check:

  • 🍎 In System Preferences → Network → Wi-Fi select network from iPhone and press Additionally. Make sure the tab is TCP/IP tuned to Use DHCP.
  • 🔒 If an error appears "Unable to connect to the network", remove the network from the list of known ones (System Preferences → Network → Wi-Fi → Advanced → Known Networks).
⚠️ Attention: On Mac with a chip M1/M2 There may be a conflict when connecting to iPhone With iOS 17+ because of the function Private Wi-Fi AddressDisable it in the network settings. Mac.

Check if the Wi-Fi adapter is enabled in Device Manager.

Remove an iPhone network from the list of saved networks (forget the network)

Update your Wi-Fi adapter driver

Try connecting via Bluetooth (if Wi-Fi doesn't work)

3. IP address conflicts and DNS settings

One of the common reasons why a computer connects to Wi-Fi from iPhone, but the internet doesn't work - conflict IP addresses or incorrect settings DNS. iPhone by default distributes addresses in the range 172.20.10.X, but if there is already a device with the same IP on the local network, the connection will fail.

How to check and fix:

  1. On iPhone open Settings → Tethering and remember the name of the network.
  2. On your computer, open Command line (Win + R → cmd) and enter: 
    ipconfig /all

    Find the block with the network name iPhone and check the fields IPv4 address And Main gateway. They must be from the same subnet (for example, 172.20.10.2 And 172.20.10.1).

  3. If the addresses conflict (for example, 192.168.1.X instead of 172.20.10.X), reset TCP/IP settings: 
    netsh int ip reset

    netsh winsock reset

    Then restart your computer.

If the problem is DNS, try manually entering public DNS from Google or Cloudflare:

  • 🌐 For Windows: Control Panel → Network → Change adapter settings → Wi-Fi → Properties → Internet Protocol Version 4 → Use the following DNS server addresses. Specify 8.8.8.8 And 1.1.1.1.
  • 🍎 For macOS: System Preferences → Network → Wi-Fi → Advanced → DNS. Add the same addresses.
Symptom Possible cause Solution
There is a connection, but no internet IP conflict or invalid DNS Reset TCP/IP or enter DNS manually
Constant connection breaks Weak signal or power saving on iPhone Disable low power mode, move devices closer
Error "Unable to connect" Incorrect password or operator restrictions Reconnect, check the tariff
The Wi-Fi network is not listed. Modem mode is disabled or has failed. iOS Reboot iPhone, enable modem mode

4. Problems with Wi-Fi adapter drivers on your PC

If the computer does not see the network from iPhone at all or it connects, but without internet, it's your fault network adapter drivers. This is especially relevant for Windows, where drivers may become outdated or conflict after updates.

  • 🔧 Open device Manager (Win + X → Device Manager).
  • Expand the section Network adapters.
  • If there is next to the adapter name exclamation mark, the driver is not working correctly.

Solutions:

  1. Update your driver:
    • Right-click on the adapter → Update driver → Automatic search.
    • If this does not help, download the driver from the manufacturer's website (for example, for Intel AX200 or Qualcomm Atheros).
  • Roll back the driverIf the problem appeared after the update: 
    Device Manager → Network Adapter → Properties → Driver → Roll Back Driver
  • Remove and reinstall the adapter:
    • Right click → Remove device.
    • Restart your computer - Windows will install the driver automatically.

      • For macOS Driver problems are less common, but if Mac does not see the network from iPhone, try resetting NVRAM:

      1. Turn it off Mac.
      2. Turn on by pressing and holding immediately Option + Command + P + R for 20 seconds.
      3. Release the keys and wait for the reboot.

    5. Mobile operator restrictions and APN settings

    Many operators (especially in Russia) blocking internet distribution on some tariffs or require additional activation. For example, MegaFon on the tariff "Everything for our own" Internet sharing is disabled by default, and Yota may require option connection "Modem".

    How to check:

    • 📱 Send to iPhone USSD request to check balance and active options: 
      *100# (MTS)

      *110*09# (Beeline)
      

      *558# (Tele2)

    • 🌐 Log in personal account operator and check the section "Services" or "Options"Look for items like Internet distribution or Modem mode.

      • If the distribution is unblocked, but the Internet still does not work, check APN settings:

      1. On iPhone open Settings → Cellular → Data Options → Cellular Data Network.

      2. Disable VPN on iPhone (Settings → VPN and device management).

      3. Check if it is turned on Airplane mode V Control center (swipe down from the top right corner of the screen).

      7. Alternative connection methods (Bluetooth, USB)

      If Wi-Fi stubbornly doesn't work, you can connect your computer to iPhone through Bluetooth or USBThese methods are less convenient, but often save lives in critical situations.

      Connecting via Bluetooth:

      1. On iPhone turn on Bluetooth And Modem mode.
      2. On the computer:
        • 🖥️ Windows: Settings → Devices → Bluetooth → Add a device. Select iPhone and confirm the pairing.

    8. Rare causes and final diagnosis

    If none of the above helps, the problem may be:

    • 🛡️ Antivirus or firewallblocking the connection. Try temporarily disabling protection (for example, Kaspersky or Avast).
    • 📡 Hardware malfunctions:
      • On iPhone: The Wi-Fi module is not working (check if the phone connects to other networks).
      • On PC: the Wi-Fi adapter is broken (try connecting to a different network).
    • 📱 iOS beta versionsIf you installed a test firmware, rolling back to the stable version may solve the problem.
