Why Your MacBook Won't Connect to Wi-Fi with Your iPhone: A Complete Troubleshooting Guide

You are trying to share the internet with iPhone on MacBook, but the laptop stubbornly doesn't detect the network or displays a connection error? This problem is familiar to many users of the ecosystem. Apple - especially after updates iOS 17 or macOS VenturaIn 80% of cases, access point settings, security protocol conflicts, or software bugs are to blame. But the good news is that most issues can be resolved independently in 5–15 minutes.

In this article we will look at all possible reasons, according to which MacBook (including models MacBook Air M1/M2 And MacBook Pro 2020–2026) does not connect to Wi-Fi network shared from iPhone (from iPhone 8 to iPhone 15 Pro Max). You'll learn how to diagnose the problem, which settings to check first, and what to do if standard methods don't help. Finally, you'll find an FAQ with answers to frequently asked questions and a device compatibility chart.

Let's note right away: if your iPhone connected to the mobile Internet (3G/4G/5G), but MacBook doesn't see his network in the list of available ones, the problem lies either in the settings modem mode, or in conflict Wi-Fi standards (For example, MacBook does not support Wi-Fi 6E, A iPhone 13+ (It's trying to distribute the network in this particular range). Let's start with the simplest thing.

📊 What iPhone do you have?
iPhone 8/SE 2020 or later
iPhone 11/12
iPhone 13/14
iPhone 15/15 Pro
I don't know the model

1. Checking the basic personal hotspot settings on your iPhone

Before you dig deeper, make sure that modem mode on iPhone is enabled correctly. Errors here are the most common cause of problems. Open Settings → Tethering and check:

  • 🔄 Allow others — the switch should be active (green). If it's gray, your carrier is blocking the feature (more on that below).
  • 📶 Connection method — choose Wi-Fi only (if you only need to connect MacBook) or Wi-Fi and Bluetooth (for a more stable connection).
  • 🔒 Wi-Fi password - If you have changed it, make sure you are entering the correct one (sometimes macOS stores the old password in the key storage).

If the switch Allow others inactive, the problem may be:

  • 📱 SIM card: some operators (eg Tele2 or Iota) by default, tethering is blocked. Call support or check your personal account.
  • 🔄 iOS updates: after installing the new version iOS (especially beta versions) the modem settings may reset. Try rebooting iPhone.
  • 🛠️ Restrictions: go to Settings → Screen Time → Content & Privacy Restrictions → Allowed Apps and make sure that the modem mode is not locked.
⚠️ Attention: If you use eSIM, check that the main data profile is activated. Some operators (e.g. MTS) allow you to distribute the Internet only from a physical SIM card.

The "Allow Others" switch is turned on|The connection method is set to "Wi-Fi" or "Wi-Fi and Bluetooth"|The Wi-Fi password has not been changed (or updated on a MacBook)|There are no restrictions in "Screen Time"|The SIM card supports tethering-->

2. Wi-Fi Standards Conflicts: Why Your MacBook Can't See Your iPhone's Network

One of the most insidious reasons is incompatibility of Wi-Fi standards. Modern iPhone (starting from iPhone 12) support Wi-Fi 6 (802.11ax) and even Wi-Fi 6E, and the old ones MacBook (until 2018) can only work with Wi-Fi 5 (802.11ac) or Wi-Fi 4 (802.11n)As a result MacBook simply does not see the network being distributed from iPhone.

How to check and fix it:

  1. On iPhone go to Settings → Wi-Fi and tap the name of your network (where you are connected). Look at the line Protocol - if it is indicated there 802.11ax or Wi-Fi 6, that's the problem.
  2. On MacBook open About This Mac → System Report → Wi-Fi and find the line Supported PHY modes. If it's not there 802.11ax, your laptop does not support Wi-Fi 6.
  3. Solution: on iPhone Force compatible mode to be enabled. To do this, disable Wi-Fi 6 in the modem settings (if there is such an option) or try distributing the Internet through Bluetooth.
MacBook model Wi-Fi 6 support Max upload speed from iPhone
MacBook Air (M1, 2020) and newer ✅ Yes Up to 900 Mbps
MacBook Pro 13" (2020, Intel) ❌ No (Wi-Fi 5 only) Up to 400 Mbps
MacBook Air (2018–2019) ❌ No Up to 300 Mbps
MacBook Pro 16" (2019) ✅ Yes Up to 800 Mbps

If your MacBook does not support Wi-Fi 6, But iPhone distributes the network in this standard, try:

  • 📱 Reboot iPhone - sometimes after reboot it automatically switches to compatible mode.
  • 🔄 Turn on airplane mode for 10 seconds, then disable and re-enable the modem mode.
  • 🔌 Connect via USB (if you have iPhone With Lightning And MacBook With USB-C, you will need an adapter).
⚠️ Attention: On iPhone 13/14/15 With iOS 17+ A bug may occur where the device only distributes the network within the range 5 GHz, and the old ones MacBook they only see 2.4 GHzThe solution is to force the range selection. 2.4 GHz in the router settings (if iPhone connected to Wi-Fi) or use Bluetooth.

3. Problems with password or authorization

If MacBook sees the network iPhone, but when connecting it gives an error "Incorrect password" or "Failed to connect", the problem lies in:

  • 🔑 Incorrect password - even if you are sure that you are entering it correctly, macOS could save the old password in Key storage.
  • 🛡️ Security protocol conflict — iPhone can use WPA3, A MacBook supports only WPA2.
  • 🕒 Time block - if you entered the wrong password several times, iOS may block the connection for 1-5 minutes.

What to do:

  1. Remove the network from your saved ones MacBook: 
    Go to Settings → Wi-Fi → Tap the "i" next to your iPhone network → "Remove This Network"

    Then try connecting again.

  2. Reset your password on iPhone: 
    Settings → Tethering & Personal Hotspot → Wi-Fi Password → Set a simple password (e.g. 12345678) and try to connect.
  3. Check the security protocol: If MacBook older than 2018, on iPhone In the modem settings, select Maximum compatibility (if there is such a clause).

Critical detail: on iPhones with iOS 17+, the Personal Hotspot password is automatically updated when you change your Apple ID password. If you recently changed your account password, update it in Personal Hotspot settings as well.

4. Software failures: reboot, network reset and updates

If the basic settings did not help, the problem may lie in software failures on one of the devices. Let's start with the simplest thing—rebooting:

  • 🔄 Reboot both devices: at first iPhone, then MacBookIn 30% of cases this solves the problem.
  • 📱 Reset network settings on iPhone: Settings → General → Transfer or reset iPhone → Reset → Reset Network Settings. Attention: After this, you will have to re-enter passwords for all Wi-Fi networks.
  • 💻 Reset SMC and NVRAM on MacBook: This helps with Wi-Fi issues. Find instructions for your model on the website. Apple (they differ for chips Intel And Apple Silicon).

If rebooting doesn't help, check software updates:

  • On iPhone: Settings → General → Software Update. Install the latest version iOS.
  • On MacBook: System Preferences → General → Software UpdateIt is especially important to update if you have macOS Monterey or older - these versions had bugs with connecting to access points.

If the problem persists after updating, try create a new access point:

  1. On iPhone Disable modem mode.
  2. Go to Settings → General → Reset → Reset network settings.
  3. Turn on the modem mode again - iPhone will create a new network with a new name and password.
⚠️ Attention: On MacBook with a chip Apple M1/M2 After resetting the SMC, you may be required to re-authorize your iCloud account. Don't be alarmed by the password prompt—this is normal.
What should I do if after resetting the network, my iPhone stops sharing the Internet altogether?

If after resetting network settings the modem mode has disappeared from the menu, check:

1. The SIM card is active and supports data transfer (call your operator).

2. In Settings → Cellular → Data Options → Cellular Data Network The correct SIM card has been selected.

3. The device does not have a configuration profile installed that blocks the modem (it is removed in Settings → General → VPN and device management).

If nothing helps, contact Apple support - it may be a hardware failure of the communication module.

5. Problems with the operator or tariff

Sometimes the problem is not in the devices, but in tariff or operator settingsHere's what you need to check:

  • 📡 Modem mode support: some tariffs (especially "unlimited" ones from MTS, Beeline or Megaphone) are blocking internet access. Call your operator and check if this option is enabled. Modem/Tetring.
  • 🌍 Roaming: If you're abroad, your carrier may block tethering. Check your roaming settings in your account.
  • 📶 Speed ​​Limit: On some tariffs, after the high-speed traffic is exhausted, the speed drops to 64–128 Kbps, and MacBook The network may not be visible. Log in to your account and check your remaining traffic.

How to check if your carrier is blocking modem mode:

  1. Try sharing the Internet connection with another device (for example, iPad or Android smartphone). If it doesn't work, the problem is definitely with the operator.
  2. Insert a SIM card from another operator into iPhone and try sharing your internet connection. If it works, call your provider.
  3. Check your operator's SMS - sometimes they send notifications about the modem being blocked (for example, Tele2 does this if there is a suspicion of "misuse of traffic").
Operator Default modem support How to enable (if disabled)
MTS ✅ Yes (on most plans) Send USSD request *111*705#
Beeline ❌ No (requires option connection) Call 0611 or through your personal account
Megaphone ✅ Yes (except for the "Everything for Communication" plans) USSD: *105*070#
Tele2 ⚠️ Yes, but it can be blocked Call support (8 800 555 06 11)
⚠️ Attention: Tariff and USSD command details are subject to change. Please check your personal account or contact your operator for the latest information.

6. Hardware problems: Wi-Fi module, antennas, physical damage

If none of the previous methods helped, the problem may be hardware. This is unlikely (especially if MacBook connects to other networks normally), but it's still worth checking:

  • 📡 Wi-Fi module on MacBook: if the laptop doesn't see it If no network is connected, the module may be faulty. Check if the Wi-Fi indicator is on (on models with Intel) or whether the icon is displayed in the menu bar.
