2. Click "Wi-Fi" → "Other networks".
3. Select "Other..." and enter the network details.

4.2. Problems with the security type

If you entered the network details manually but the connection does not occur, check:

• 🔒 Security type: Some older laptops do not support WPA3Switch to . WPA2-PSK in the phone settings.
• 🔑 Password: it must not contain Cyrillic or special characters (for example, #, !, @). Try setting a simple password like 12345678 for the test.
• 📡 Network mode: if the phone is distributing in mode 802.11n (Wi-Fi 4), and the laptop only supports 802.11ac (Wi-Fi 5) may cause conflicts. Try changing the mode in your phone settings (if such an option is available).

Make sure the network is not hidden (Hidden SSID)|Check the security type (WPA2-PSK)|Set a simple password for testing|Try changing the band (2.4 GHz / 5 GHz)|Update the Wi-Fi adapter driver-->

5. Conflicts with antivirus or firewall

Security programs (Kaspersky, ESET NOD32, Avast, built-in Windows Defender) sometimes block connections to "untrusted" networks, especially if the hotspot is broadcast from a phone. The problem may also be in Windows Firewall or macOS.

How to check:

• 🛡️ Temporarily disable your antivirus and try connecting again.
• 🔥 On Windows:
  1. Open Control Panel → Windows Firewall → Turn firewall on or off.
  2. Disable it for private networks and try connecting.
• 🍏 On macOS:
  1. Open System Preferences → Security & Privacy → Firewall.
  2. Click "Firewall Settings" and temporarily disable it.

If the network appears after disabling protection, add it to the exceptions of your antivirus or firewall. For example, in Kaspersky it's done like this:

1. Open the program settings → "Net".
2. Find the section Network Management and add a new network to "Trusted".

6. Hardware malfunctions or interference

If all software methods have been tried, but the laptop still does not see Wi-Fi from the phone, the reason may lie in hardware problems:

• 📡 The Wi-Fi module on the laptop is damaged. (for example, after a fall or liquid spill). Check if the laptop sees other networks (for example, a home router). If not, the module is faulty.
• 📱 The Wi-Fi chip on the phone is faultyTry sharing your internet connection from another smartphone. If the laptop sees the new network, the problem is with the original phone.
• 📶 Strong interferenceIf there are many networks nearby on the same channel (check through the app) Wi-Fi Analyzer (On Android), your phone may be broadcasting on a congested frequency. Try changing the channel in your access point settings.
• 🔋 Energy savingOn some laptops (Lenovo, HP) In battery mode, the Wi-Fi adapter is disabled to save battery power. Connect your laptop to a network or check your power settings.

🔧 How to check the Wi-Fi module on a laptop:

1. Open device Manager and find your adapter.
2. Check his status: if it is written "This device is working properly.", the problem is most likely software related.
3. If the adapter displays an error, try reinstalling the driver or contacting the service center.

⚠️ Attention: if the laptop doesn't see it not a single one Wi-Fi network (including home router), and the adapter is displayed with an error in the device manager Code 10 or Code 43, this almost always means hardware failureIn this case, only replacing the module will help.

7. macOS Features: Why MacBook Can't See iPhone's Wi-Fi

Owners MacBook And iPhone often face a unique problem: despite the fact that both devices are Apple, they sometimes "don't see" each other. Here are the main reasons and solutions:

• 🔄 Apple ID conflictIf on iPhone option enabled "For contacts only" in modem mode, MacBook will not be able to connect if not authorized in the same Apple IDDisable this option in the tethering settings.
• 🔒 Continuity BlockingOn . macOS Ventura and newer protection may be triggered if MacBook And iPhone not synchronized through iCloud. Check that the following are enabled on both devices:
  • Wi-Fi And Bluetooth;
  • Handoff (System Preferences → General → AirDrop and Handoff);
  • One and the same Apple ID V iCloud.
• 📡 Problems with the Broadcom chip. Many MacBook (especially models 2018–2020) use Wi-Fi chips Broadcom, which sometimes conflict with iPhone in modem mode. The solution is to reset network settings:

  sudo ifconfig en0 down
  sudo ifconfig en0 up

  (run in Terminal).

🔹 macOS Sonoma specific bug: if after the update MacBook stopped seeing the access point from iPhone, try:

1. Turn off Wi-Fi on MacBook.
2. Enable modem mode on iPhone.
3. Wait 10 seconds and turn Wi-Fi back on. MacBook.

FAQ: Frequently Asked Questions

My laptop sees other networks, but not my phone's Wi-Fi. What's wrong?

Most likely, the problem is in the phone settings:

• Check that the access point is turned on and is broadcasting within range. 2.4 GHz (and not only 5 GHz).
• Make sure the network is not hidden (Hidden SSID).
• Try changing the security type from WPA3 on WPA2-PSK.

If this does not help, update the Wi-Fi adapter driver on your laptop.

My phone is broadcasting Wi-Fi, but my laptop connects and then immediately disconnects. What should I do?
This problem is usually related to:
• IP address conflict: may be enabled on the phone and laptop DHCP, but the addresses are not being issued. Try manually entering the IP address on the laptop (for example, 192.168.43.100 with a mask 255.255.255.0).
• Energy saving: on Windows open Device Manager → Network Adapters → Your Wi-Fi Properties → Power Management and uncheck "Allow the computer to turn off this device to save power".
• Antivirus: Temporarily disable protection and check the connection.
Is it possible to share Wi-Fi from a phone without a password?

Technically yes, but:

• On Android select security type Open Network (not recommended due to security risks).
• On iPhone The password is required and cannot be removed.

⚠️ Attention: An open network allows anyone to connect to your phone and potentially intercept your traffic. Use this mode only in trusted environments.

• Device restrictions: on some phones (Xiaomi, Huawei) There is a limit on the number of connected devices (usually 5-10). Disconnect unnecessary gadgets.
• IP conflict: manually assign IP on the laptop (eg. 192.168.43.50).
• MAC address blocking: if filtering is enabled on your phone MAC, add the laptop address to the whitelist.
