Critical Security Warning

If you are still using the default WiFi password printed on the router’s sticker, change it immediately. ZTE F663NV3a: Default Passwords, Login Guide, and Security

Here’s why:

  • Default passwords are publicly known and easily searched online.
  • Neighbors or wardrivers can connect to your network.
  • Once on your WiFi, they could try to access your router settings.

1. Check ISP-provided password

Some ISPs set a unique admin password printed on the router sticker – use that exactly as written (case‑sensitive). Model: ZTE F663N V3A Function: 4G LTE CPE

2. Factory Reset (last resort)

  • Press and hold the Reset button (small hole on the back) for 10–15 seconds using a paperclip.
  • All settings (including Wi-Fi name/password) will be erased.
  • After reboot, use the default credentials from the sticker.

⚠️ Resetting will disconnect your internet if you have ISP-specific VLAN or PPPoE settings. You may need to reconfigure them.
