2. The laptop doesn't see the network: problems with Wi-Fi drivers

If iPhone It's distributing Wi-Fi, but the laptop doesn't detect the network in the list of available connections. It's the culprit. Wi-Fi adapterMost often this is associated with:

• 🖥️ Missing or outdated drivers (especially after a Windows update)
• 🔌 Disabled adapter in the Device Manager
• ⚡ Energy saving, which turns off Wi-Fi to save battery life

How to check and fix:

For Windows 10/11:

1. Click Win + X and select "Device Manager".
2. Expand the branch Network Adapters.
3. Find the device with the words Wireless, Wi-Fi or Network Adapter (For example, Intel Wi-Fi 6 AX200 or Qualcomm Atheros).

sudo ifconfig en0 up

(Where en0 — your Wi-Fi adapter; check the name via networksetup -listallhardwareports).

3. Wi-Fi channel conflict: why your laptop can't see the network

Many people don't know that iPhone when distributing Wi-Fi it uses random channel in the 2.4 GHz or 5 GHz range. If this channel is occupied by another device (for example, neighboring routers), the laptop may simply not detect the network.

How to check and fix:

1. Install a Wi-Fi network analysis utility on your laptop, for example:
   • 🪟 WiFi Analyzer (Windows)
   • 🍎 NetSpot or Wireless Diagnostics (macOS, built-in utility)

See which channels are the most loaded in your location.

On iPhone force another channel through Settings → Tethering → Network name (click on the title and select "Channel").

If you have iPhone older iPhone 12, it may not support the range 5 GHz for modem mode. In this case:

• 📶 Force enable 2.4 GHz only in the distribution settings.
• 🔄 Reboot iPhone and a laptop.

4. Blocking by antivirus or firewall

Sometimes security software On a laptop, it blocks connections to "unknown" networks, especially if they're accessed from mobile devices. This applies to:

• 🛡️ Antivirus (Kaspersky, ESET, Avast)
• 🔥 Windows/macOS Firewall
• 🌐 VPN clients (for example, NordVPN or ProtonVPN)

⚠️ Attention: Don't leave your antivirus and firewall disabled for long periods of time! Be sure to re-enable your protection after testing.

5. IP address issues: DHCP not providing settings

If the laptop sees the network with iPhone, but when connecting it gives an error "Unable to obtain IP address" or Limited Access, the problem is in the settings DHCPIt is a protocol that automatically assigns IP addresses to devices on a network.

How to fix:

Method 1: Reset network settings on your laptop

• 🪟 Windows: Run in the command prompt (Win + R → cmd):

  ipconfig /release
  ipconfig /renew
  netsh winsock reset

  Then restart your laptop.

• 🍎 macOS: Open Terminal and enter:

  sudo networksetup -renewDHCP Wi-Fi

  (you will need to enter the administrator password).

Method 2: Manually assigning an IP address

If DHCP doesn't work, assign a static IP manually:

1. On your laptop, open your Wi-Fi network properties.
2. In IPv4 settings, select "Use the following IP address".
3. Enter:
   • IP address: 192.168.2.2
   • Subnet mask: 255.255.255.0
   • Default gateway: 192.168.2.1
   • DNS: 8.8.8.8 (Google) or 1.1.1.1 (Cloudflare)

On iPhone Check that the modem mode is enabled in the settings Maximum compatibility (this will enable support for older devices).

Why might DHCP not work?

Most often, this occurs due to an IP address conflict (for example, if there is already a device with the address 192.168.2.1 on the network) or if the “Hide IP Address” mode is enabled on the iPhone (Settings → Wi-Fi → [i] next to the network).

6. Hardware problems: when a hardware failure is to blame

If none of the previous methods helped, the problem may be in hardware:

• 📱 A faulty Wi-Fi module on an iPhone (rarely, but it happens after falls or exposure to moisture).
• 💻 The Wi-Fi adapter in the laptop is broken. (for example, after overheating or mechanical damage).
• 🔋 Weak iPhone battery — when the battery charge is low (less than 20%), the modem mode may not work stably.

How to diagnose:

1. Try distributing Wi-Fi with iPhone to another device (for example, a tablet or a second laptop). If the network is not visible there either, the problem is iPhone.
2. Connect your laptop to a different Wi-Fi network (for example, your home router). If it still doesn't see the network, the laptop's adapter is at fault.
3. Check it out iPhone for liquid (insert the SIM card - if the tray is wet, this is a bad sign).

Solutions:

• 📱 For iPhone: reset network settings (Settings → General → Transfer or reset iPhone → Reset → Reset Network Settings). If this doesn't help, contact the service center.
• 💻 For a laptop: connect an external USB Wi-Fi adapter (costs from 500 ₽) and check if it sees the network with iPhoneIf yes, your built-in adapter is faulty.

⚠️ Attention: If the laptop stops seeing All If you're having trouble connecting to a Wi-Fi network after updating the BIOS or reinstalling Windows, the Wi-Fi controller is most likely disabled in the UEFI settings.

1. Is mobile internet enabled? iPhone (Settings → Cellular → Cellular Data).
2. Are there any tariff restrictions (some operators block modem mode).
3. Is it updated? iOS to the latest version (Settings → General → Software Update).

If nothing helps, reset your network settings iPhone.

My laptop connects to Wi-Fi from my iPhone, but the internet isn't working. What's wrong?

Possible reasons:

• 📵 On iPhone no mobile internet (check your balance or coverage area).
• 🔄 DNS conflict: try manually entering 8.8.8.8 in the IPv4 settings on the laptop.
• 🛡️ A firewall or VPN is blocking traffic (please disable them during the test).

Is it possible to share Wi-Fi from an iPhone without a password?

No, iOS Always requires a password for modem mode. However, you can:

1. Set a simple password (eg. 12345678).
2. Use a USB or Bluetooth connection (no password required).

Why does my laptop see the network from my iPhone, but it doesn't connect and instead asks for a password over and over again?

This is a typical problem when:

• 🔑 Incorrect password (check the letter case!).
• 📡 Conflict of Wi-Fi standards (try on iPhone turn on Maximum compatibility).
• 🖥️ Outdated Wi-Fi drivers on your laptop (update them).
