2. The laptop doesn't see the iPhone's hotspot.

If the list of available networks on your laptop does not show the name of your access point at all (by default it is iPhone [your name]), the reasons may be the following:

Reason 1: Bluetooth or Wi-Fi is disabled on the iPhone. Wi-Fi tethering requires both devices to be active. Check:

  • 🔵 Bluetooth: Settings → Bluetooth (must be enabled even if connected via Wi-Fi).
  • 📶 Wi-Fi: Settings → Wi-Fi (turned on, but not connected to another network).

Reason 2. Wi-Fi channel conflict. Modern iPhone (starting from iPhone 12) support Wi-Fi 6 (802.11ax) and can automatically switch channels 5 GHz or 6 GHzOld laptops (especially with adapters) Wi-Fi 4 or Wi-Fi 5) they are not seen.

Solution: Force the range to be limited iPhone:

  1. Open Settings → Personal Hotspot → Wi-Fi Password.
  2. Tap and hold the password field for 2 seconds – a menu will appear "Max. compatibility".
  3. Enable this setting now iPhone will only use 2.4 GHz (compatible with all devices).
What should I do if the "Max Compatibility" option is missing?

This feature was introduced in iOS 16. If you have an older version, update the software. Alternatively, temporarily disable Wi-Fi on other devices connected to the same network to prevent your iPhone from conflicting with them.
