Add wireless connectivity to your desktop computer with the AC1200 Dual-Band Wireless AC PCIe Network Adapter from StarTech. This Wi-Fi adapter installs into a PCIe slot on the motherboard and grants you dual-band connectivity with 802.11ac networks. With dual-band support, you'll be able to connect to the 2.4 GHz and 5 GHz band with speeds of up to 300 Mbps and 867 Mbps respectively. Furthermore, it's also backward compatible with 802.11a/b/g/n networks. Attach the two antennas to the card and you're all set. Otherwise, you can extend or get a stronger signal by installing the antennas on the included antenna base and moving it around.
