Kt Giga Wifi Wave 2 May 2026

The router has lost its WAN connection to the fiber modem. Fix: Reboot the fiber ONT (usually a white box on the wall). Wait 2 minutes. Then reboot the KT Gig WiFi Wave 2. If red persists, call KT customer service (100) – they can remotely reset the port.

The "Wave 2" designation isn't just marketing—it refers to the second, more advanced generation of the 802.11ac standard.
