  • 🔋 The router is turned on and operating normally. If the lights are flashing abnormally (for example, red), first reboot the device.
  • 📱 On iPhone the current browser is installed (Safari, Chrome or Firefox). Older versions may display the router interface incorrectly.
  • 🔐 You have access to current Wi-Fi password or button WPS on your router (if supported). Otherwise, you'll have to reset the settings.

If you don't remember your current Wi-Fi password, but iPhone is already connected to the network, you can find it in the device settings. To do this, go to Settings → Wi-Fi, tap the ⓘ icon next to your network name and tap the field PasswordThe system will require you to confirm your identity through Face ID, Touch ID or a password code. This method only works on iPhones with iOS 16 and later—on older versions, the password is hidden.

⚠️ Important: If your router displays an "Incorrect login/password" error when accessing the settings, it's likely that someone has previously changed the access details. In this case, only a factory reset will help (see Section 5).

2. Method 1: Changing the password via the router's web interface (universal method)

This is the most reliable method, which works on 99% of modern routers. The instructions are suitable for devices TP-Link, ASUS, Keenetic, D-Link, Zyxel and other brands. The main thing is to know Router IP address and login details (login/password).

  2. Log into your router settings:
    • Open your browser (Safari or Chrome) and enter the IP address in the address bar.
    • Enter your login and password (by default this is often admin/admin or admin/password). If the data has changed, use the current one.

    • Look for tabs in the menu Wireless, Wi-Fi, Wireless network or Network.

    After saving, the router will reboot and all devices will be disconnected from the network. Reconnect using the new password.

    Make sure the "Security Type" field is set to WPA2-PSK or WPA3 (not "Open Network")

    Write down the new password in a safe place (for example, in the iPhone's notes with the lock)

    Check that the Wi-Fi frequency (2.4 GHz or 5 GHz) has not changed accidentally

    3. Method 2: Using the router's mobile app

    Many router manufacturers offer official apps for managing the device from a smartphone. This is more convenient than a web interface, especially for beginners. Let's look at the process using popular brands as examples.

    Router management apps:

    • 📱 TP-Link: Tether (App Store)
    • 📱 ASUS: ASUS Router (App Store)
    • 📱 Keenetic: Keenetic (App Store)
    • 📱 D-Link: D-Link Wi-Fi (App Store)

    Instructions for TP-Link Tether (similarly for other applications):

    1. Download and install the application from App Store.
    2. Connect iPhone to the router's Wi-Fi network.
    3. Open the app and follow the connection instructions (you may need to scan the QR code on your router).
    4. Go to the section Wi-Fi settings or Wireless.
    5. Find the field Password and enter the new key.
    6. Save the changes and wait for the router to reboot.

    The advantage of this method is its intuitive interface and the ability to manage the router remotely (if supported). However, not all router models have mobile apps, so the web interface remains the universal solution.

    ⚠️ Attention: If after changing the password through the application Wi-Fi stops working, check whether the channel or operating mode settings have been reset (for example, switching from 802.11n on 802.11ac may cause problems with older devices).
