Why Your Laptop Won't Detect Wi-Fi on Your iPhone 13: A Complete Troubleshooting Guide

You are trying to share the internet with iPhone 13 to your laptop, but the device stubbornly refuses to detect the access point you've created? This problem is more common than you might think—and the causes can lie in your smartphone settings, your laptop configuration, or even the operating system itself. In 80% of cases, the problem can be resolved in 5-10 minutes if you know where to look.

The situation is complicated by the fact that iPhone 13 (like other models with iOS 15+) uses the protocol Wi-Fi 6 and dynamic frequency changes, which aren't always handled correctly by older laptop adapters. And if you're connecting to an access point for the first time, the system may block the connection due to security settings. Let's figure out how to diagnose and fix the problem without calling a service center.

In this article you will find:

  • 🔍 Diagnosing the problem — How to determine what exactly the problem is: a phone, a laptop, or a router
  • ⚙️ Step-by-step instructions For Windows 10/11, macOS And Linux
  • 📱 Hidden iPhone 13 Settingsthat interfere with Wi-Fi distribution
  • 🛠️ Alternative methods connections if the standard method does not work

1. Checking basic Wi-Fi sharing settings on iPhone 13

Before you dig deep, make sure the access point is on iPhone 13 Enabled correctly. Even experienced users make mistakes here.

Open Settings → Tethering and check:

  • 🔄 Allow others to connect — the slider should be green. If it's gray, tap it.
  • 🔒 Wi-Fi password — By default, this is a random set of characters. Remember it or change it (minimum 8 characters, including numbers).
  • 📶 Maximum number of connections — If other devices are already connected to the hotspot, the laptop may not see the network due to the limit.

If after turning on the modem mode the laptop still does not see the network, try restart your iPhoneSometimes the Wi-Fi module freezes after a long period of use. To fix this, hold down the button Nutrition + any of the volume buttons until the slider appears Turn off.

2. Laptop Wi-Fi adapter compatibility issues

Laptops with Wi-Fi adapters older than 2018 may not support the Wi-Fi 6 (802.11ax) protocol, which the iPhone 13 uses by default when sharing the Internet. As a result, the network simply does not appear in the list of available ones.

To check this:

  1. On Windows: open device Manager (keys Win + X), find the section Network adapters and look at the Wi-Fi module model. If the name contains AC (For example, Intel Dual Band Wireless-AC 7260), your adapter only supports Wi-Fi 5.
  2. On macOS: open About This Mac → System Report → Network → Wi-Fi and check the line Supported PHY modes.

Solutions:

  • 🔄 Force compatibility mode on iPhone: go to Settings → Tethering → Maximum Compatibility (if the option is there) This will force the phone to use Wi-Fi 4 (802.11n), which all adapters support.
  • 🖥️ Update your Wi-Fi adapter driver on your laptop. Download the latest version from the manufacturer's website (not through Windows Update!).
  • 🔌 Use a Wi-Fi 6 USB adapter, if the built-in module is outdated. Suitable models: TP-Link Archer T4U Plus or ASUS USB-AX56.

3. Conflict of Wi-Fi channels and frequencies

iPhone 13 by default it distributes the Internet at a frequency 5 GHz, if available. However, many laptops (especially budget ones) do not support this frequency or do not work well with automatic channel selection.

How to check and fix it:

  1. On iPhone open Settings → Wi-Fi and check which network you're connected to (2.4 or 5 GHz). If it's 5 GHz, the access point will also try to use that frequency.
  2. Enable modem mode and check if the network appears on your laptop. If not, force it to switch. iPhone on 2.4 GHz:
    • Turn off Wi-Fi on your phone.
    • Turn on Airplane mode for 10 seconds, then turn off.
    • Turn on Wi-Fi and connect to the network at the frequency 2.4 GHz (if the router supports both frequencies, the network usually has a suffix _2G or _2.4).
    • Now turn on the modem mode - the network should appear on the laptop.
How do I know what frequency my laptop supports?

On Windows: Open a command prompt (Win + R → cmd) and enter:

netsh wlan show drivers

Look for the line Supported radio typesIf only there 802.11n or 802.11g, your adapter only works at 2.4 GHz.

If the laptop still does not see the network, the problem may be in channel selectionSome 2.4 GHz channels (e.g., 12-14) are restricted in some countries. Try manually setting channel 1, 6, or 11—these are universal.

4. Blocking the connection at the laptop OS level

Sometimes the problem lies not with the hardware, but with the operating system settings. Let's look at solutions for different platforms.

For Windows 10/11:

  • 🔧 Reset network settings:
    1. Open Settings → Network & Internet → Status.
    2. Click Network reset and confirm the action.
    3. Restart your laptop.
  • 🛡️ Disabling firewall/antivirus: Temporary shutdown Windows Defender or a third-party antivirus (for example, Kaspersky, Avast) may help if they are blocking new connections.
  • 📡 Manual IP configuration:
    1. Open Control Panel → Network and Sharing Center → Change adapter settings.
    2. Right click on Wi-Fi, select Properties → Internet Protocol Version 4 (TCP/IPv4).
    3. Check the box Use the following IP address and enter:
      • IP: 192.168.44.10
      • Mask: 255.255.255.0
      • Gateway: 192.168.44.1 (standard for iPhone)

For macOS:

  • 🔄 Resetting the network list: Open Terminal and enter: 
    sudo rm /Library/Preferences/SystemConfiguration/NetworkInterfaces.plist

    sudo rm /Library/Preferences/SystemConfiguration/preferences.plist

    Then restart your Mac.

  • 🔒 DNS setup: Go to System Preferences → Network → Wi-Fi → Advanced → DNS and add 8.8.8.8 (Google DNS).

Is the Wi-Fi adapter enabled (physical button or Fn+F2)?

Are your network card drivers updated?

Is Airplane Mode turned off?

Have you tried connecting to another network (to check the adapter)?
