Kt Giga Wifi Wave 2 [upd] Instant
As of 2025, Wi-Fi 6 is mainstream. The Wave 2 is an AC (Wi-Fi 5) router. While AC Wave 2 is excellent, it lacks OFDMA (which improves efficiency with many low-bandwidth devices) and cannot hit 1.2 Gbps per stream. If you have Wi-Fi 6 devices (iPhone 15, Galaxy S24, PS5), you are missing out on about 20-30% efficiency gains in congested areas.
