ASUS PCE-AC51 - Network Adapter, Multicolour

The ASUS PCE-AC51 (90IG02S0-BO0010) is a dual-band PCI Express Wi-Fi adapter designed for desktop PCs. It provides wireless connectivity to desktops that lack built-in networking hardware, allowing them to connect to local routers. The card uses the Wi-Fi 5 (802.11ac) standard to connect to local area networks, reaching a maximum data transfer rate of 433 Mbit/s. This bandwidth is sufficient for web browsing, media streaming, and general home or office network use.

The adapter installs into an available PCI Express slot on the motherboard. It uses external antennas, which attach to the rear bracket, to manage signal reception. These antennas use standard R-SMA connectors, allowing users to adjust their position to improve the connection to the access point. The card is compatible with Linux and various Windows versions, including specific support for Windows 8.1.

• Dual-band support (2.4 GHz and 5 GHz) for connection to legacy and modern routers
• Backward compatible with IEEE 802.11a, 802.11b, 802.11g, and Wi-Fi 4 (802.11n) standards
• Supports 64-bit/128-bit WEP, WPA-PSK, and WPA2-Enterprise encryption protocols
• Lightweight 50 g design, placing minimal physical strain on the motherboard's PCIe slot
