The QWA-AC2600 is a 2.4/5 GHz Dual Band Dual Concurrent (DBDC), 4 x 4 Multi-user MIMO (MU-MIMO), low-profile PCI Express (PCIe) 2.0 x1 wireless adapter with two Qualcomm QCA9984 NICs that supports up to 2533 Mbps (800 Mbps for IEEE 802.11n (2.4 GHz) and 1733 Mbps for IEEE 802.11ac (5 GHz)). The QWA-AC2600 can be used as an access point or a base station with Ubuntu/Linux PCs or QNAP NAS. Combining the higher compatibility of 802.11n and faster connection of 802.11ac, the QWA-AC2600 enables versatile applications including wireless LANs in the workplace and Internet of Things (IoT) deployment in the field.

A tailor-made private wireless network that meets your needs
The QWA-AC2600 is compatible with most PCIe-enabled QNAP NAS*. When used with the WirelessAP Station app your NAS will evolve into a high-performance wireless access point that can be connected to from multiple devices. The QWA-AC2600 can also be used to extend your wireless network coverage. Combined with useful features (including DHCP and NAT) provided by the Network and Virtual Switch app, the QWA-AC2600 can be used for a variety of applications, delivering private, fast, low-latency and secure connectivity across your home and/or workplace.

Turn your Ubuntu/Linux PC or QNAP NAS into a wireless access point/base station
The QWA-AC2600 can turn your Ubuntu/Linux PC or QNAP NAS into a wireless access point/base station for other wireless devices to directly access data stored on it. The QWA-AC2600's 2.4/5 GHz DBDC design can be configured to utilize two wireless networks for boosting performance. For a single Ubuntu/Linux PC or QNAP NAS, multiple sets of QWA-AC2600 can be installed to enable a more flexible deployment and expansion for wireless network applications which require security, privacy and high performance.
