ASUS PCE-AC56 Dual-Band AC1300 WiFi PCIe Adapter - Fast Desktop

Our review of the ASUS PCE-AC56 finds it is a straightforward way to add modern wireless to a desktop PC, especially for users who need a reliable, higher-speed connection without running Ethernet cables. The biggest reason to buy is its combination of a next-generation 802.11ac chipset and selectable dual-band operation, which delivers up to 867 Mbps on the 5 GHz band and improved range over legacy cards, making it a practical upgrade for older desktops or home offices that need better wireless performance.

Key Features

• 802.11ac performance: The next-generation 802.11ac chipset provides super-fast connections up to 867 Mbps on 5 GHz for smoother streaming and lower latency in online games.
• Dual-band flexibility: Selectable 2.4 GHz or 5 GHz operation lets users prioritize range or speed and maintain compatibility with older devices.
• Broadcom TurboQAM: Enhanced 802.11n speeds up to 400 Mbps on compatible networks, giving a useful boost for mixed environments.
• High-power design: Built-in high-power components and antennas reduce dead zones and extend coverage around a typical home or small office.
• Security and setup: Supports 64/128-bit WEP, WPA/WPA2-PSK and WPS for secure connections with a simple install process on supported Windows systems.
• Thermal stability: A dedicated heatsink helps ensure stable and continuous operation under sustained network load.

Who It's For

The PCE-AC56 is aimed at desktop owners who want an immediate 802.11ac Wi-Fi upgrade without replacing the entire system or running Ethernet. It is well suited to home users streaming HD video, small office workers needing reduced latency, and gamers who want improved wireless speeds compared with older 802.11n adapters.

It is less appropriate for users on non-Windows platforms, since OS support is listed for Windows versions only, or for those who require the absolute latest Wi-Fi 6 features and throughput. If you need the newest standard or multi-Gig throughput, look for a Wi-Fi 6/6E option instead.
