The 4 x 5 dBi, fixed antennas allow sending and getting many data streams at once. This boosts overall throughput and improves Wi-Fi performance. Many IoT devices, smart home devices, and older Wi-Fi devices mainly use the 2.4 GHz band. This router operates on both the 2.4GHz and 5GHz frequency bands. It lets you connect devices to the best band for their needs. The AC Wi-Fi router is backward compatible with older Wi-Fi devices that support 802.11a/b/g/n standards.

Real-world RT-AC58U router speeds are lower than its theoretical maximum speed. WEP was the first Wi-Fi security protocol. But it is now seen as weak and easy to hack. The introduction of WPA2 (Wi-Fi Protected Access 2) improved upon WEP. It provides stronger security. WPS (Wi-Fi Protected Setup) provides an easy method. It connects devices to a Wi-Fi network.
