300 Mbps PCIe Wireless N Adapter

The STARTECH PEX300WN2X2 adds 802.11n Wi-Fi to any desktop with a free PCI Express x1 slot. Its 2x2 antenna design delivers up to 300 Mbps over the 2.4 GHz band while maintaining backward compatibility with 802.11b/g networks at 11 and 54 Mbps. Security support includes WEP, WPA, WPA2-PSK and WPA2 Enterprise encryption. A low-profile bracket is included for slim chassis installations.

Suits older desktops needing basic 2.4 GHz

Builders upgrading legacy Windows XP through 10 systems or Linux kernels 2.6.32 to 4.11.x will find native driver support. The card requires a PCI Express x1 slot and fits low-profile cases with the supplied bracket. Users needing 5 GHz band access, 802.11ac or ax speeds, or Bluetooth integration should look at something else. The 2.2 dBi antennas provide modest range for typical home or office distances.

Fits a PCIe x1 slot and frees USB ports

Installation uses a single PCI Express 2.0 lane, leaving USB headers and ports free for peripherals. The half-height PCB measures 0.70 by 1.90 by 3.00 inches and weighs 0.08 lb, so it clears most expansion areas. Two detachable antennas connect via RP-SMA connectors for flexible positioning. Operating temperatures span -10 to 70 °C, making the adapter suitable for standard indoor environments.
