A tailor-made private wireless network that meets your needs

By installing the QWA-AC2600 and 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. (WirelessAP Station requires Container Station to be installed on your QNAP NAS.)
Boost your Wi-Fi coverage
Deploy your QNAP NAS as a wireless access point to improve coverage. With the QWA-AC2600 and the WirelessAP Station app, your NAS is transformed into a high-performance wireless access point. Just place the NAS in a more centralized location and it will help lengthen the reach of your existing Wi-Fi network and eliminate potential dead zones. alt
Directly access your NAS
With the QWA-AC2600 and the WirelessAP Station app, your NAS can perform as a high-performance wireless access point that can be accessed by multiple devices. Your devices can directly access data stored on the NAS and in bypassing the router, access speeds to the network will not be affected. alt

Protect important data with snapshots

Snapshots help protect your data by fully recording the NAS system state and metadata. If files are accidentally deleted or modified or the system is afflicted by ransomware, you can use snapshots to quickly restore files to a previously-recorded state. QNAP snapshots are block-based and only record the changed data. Not only does this save storage space but also reduces the time required to back up and restore data. The TS-251B supports up to 1,024 snapshots per NAS and up to 256 snapshots per volume or LUN.alt
