1. Preparation: What to do before changing your password

Before changing your password, make sure your phone is connected to the same Wi-Fi network you want to set up. If you've already forgotten your current password and can't connect, you'll have to use Ethernet cable (if applicable) or reset the router to factory settings—but this is a last resort. Also check:

  • 🔋 Phone battery: If the battery runs out during setup, changes will not be saved.
  • 📶 Wi-Fi signal: You must be in a strong reception area, otherwise the control panel may not open.
  • 📱 Browser: use Chrome, Safari or Firefox - some proprietary browsers (for example, Samsung Internet) may not display the router interface correctly.

If you don't know your current Wi-Fi password but are connected to the network on another device (such as a tablet or second phone), you can view it in that device's settings. Android come in Settings → Wi-Fi → [your network] → Share (PIN or fingerprint required). iPhone the path is this: Settings → Wi-Fi → (i) next to the network name → "Password" field.

⚠️ Attention: If you reset the router to factory settings (using the button Reset (on the router's case), all devices will disconnect from the network, and the Wi-Fi name and password will return to the default values ​​(usually found on a sticker on the bottom of the router). This will help if you've completely lost access, but you'll have to set up the network again.
