A well-positioned antenna can reduce interference and signal weakening. This leads to a more reliable connection. The 2.4 GHz band is widely supported by many devices. This includes older ones that may not work with the 5 GHz band. Using the 5 GHz band can move some devices from the crowded 2.4 GHz band. This cuts congestion and boosts the network. The AC Wi-Fi router is backward compatible with older Wi-Fi devices that support 802.11a/b/g/n standards.

Real-world Archer C20i 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.
