  1. Install on iPhone 6 application WPS Connect (available on the App Store).
  2. Launch the app and click Scan.
  3. Find your network in the list and click Connect.
  4. Press the button within 2 minutes WPS on the router (usually it is labeled or blinking).

Method 2: Connecting via QR code

Many modern routers (for example, TP-Link, Keenetic) allow you to generate a QR code for connection. Here's how:

  1. Go to the router's web interface (usually at 192.168.1.1 or 192.168.0.1).
  2. Find the section Wi-Fi → QR code (the name may differ).
  3. Download the QR code to another phone or print it out.

  • 🔐 Security type: Use WPA2-PSK with encryption AES. Turn it off. WPA3 And TKIP.
  • 📶 Channel and width: For 2.4 GHz select a channel 1, 6 or 11 (they intersect the least). Set the channel width 20 MHz.
  • 🔄 DHCP: Make sure the DHCP server is enabled and the IP address range is not exhausted.

If your router has this feature Beamforming or MU-MIMO, disable it - these technologies are optimized for new devices and may cause problems on iPhone 6.

For routers TP-Link The path to the settings is usually like this:

192.168.0.1 → Wireless → Wireless Settings
