Unable to automatically connect to Wi-Fi

• Avoid giving your Wi-Fi network a common name.
  • Some wireless routers are preconfigured with a common SSID (network name) such as "wireless" or "default."
  • If your desired Wi-Fi network has a common SSID, try changing the SSID to something unique2.
• If your desired Wi-Fi network has a unique SSID, reset network settings by tapping Settings > General > Reset > Reset Network Settings. Note: This will reset all network settings including:
  • previously connected Wi-Fi networks and passwords
  • recently used Bluetooth accessories
  • VPN and APN settings

Best of luck,

Mario
