Fast, reliable Wi-Fi

Equipped with three powerful antennas and support for the latest 802.11ac wireless networking standard, Synology Router RT1900ac broadcasts both 2.4 and 5 GHz spectrums for combined data transfer speeds of up to 1900 Mbps. Never worry about speed bottlenecks even when multiple people are connected to the network.

Lag-free online gaming

Take advantage of easy-to-use bandwidth prioritization and network traffic controls, so your games always get the speed and low latency they need.

Smooth video streaming

Enjoy buffer-free playback when streaming 4K movies from your favorite online video service, or play home videos stored on external storage directly on a DLNA compatible TV or media player.

Fast file transfers

Share important files and documents quickly and smoothly when collaborating with business partners or others.

Robust connectivity with Beamforming

Traditional routers broadcast wireless signals in all directions, regardless of the position of your laptop or smartphone. With smart Beamforming technology, Synology Router RT1900ac focuses wireless signals toward up to six supported devices, reducing latency, economizing power consumption, and improving wireless range.

Powerful connectivity management

For advanced home users and company admins, Synology Router Manager 1.1 delivers tools to manage connectivity so your network runs smoothly and just the way you want.

Smart WAN

For those who need uninterrupted network connectivity, Smart WAN allows Synology Router RT1900ac to connect to the Internet via two network interfaces. If one of the connections goes offline due to ISP problems or other issues, traffic can failover to the other interface. Additionally, load balancing can spread traffic across both interfaces according to customizable settings, allowing you to route traffic through a specific interface according to the destination or source address.

Smart Connect

Not sure which devices should connect to the 2.4 and 5 GHz bands? With Synology's Smart Connect wireless technology, devices are connected to the most appropriate band automatically according to preset or customizable criteria, letting users experience the best Wi-Fi without worrying about technical details.

Content filtering & monitoring

Synology Router Manager (SRM) 1.1 includes advanced traffic tools that surpass the common router. Limit bandwidth consumption, block malicious content, and fine-tune how data travels through your home or office network.

Application Layer QoS

Powered by a deep packet inspection engine, Application Layer QoS (Quality of Service) lets you see how much bandwidth is consumed by individual applications and devices. If someone is hogging too much bandwidth on non-essential applications — like YouTube or Spotify — you can restrict the amount of bandwidth the device can use for the specific application, without affecting the bandwidth available for other applications.
Traffic report

To better manage and assess bandwidth requirements, you can generate easy to understand reports detailing the traffic usage of applications and devices over a specific period of time. Network administrators can use these reports to better understand traffic, check if certain devices or applications are consuming too much bandwidth, and investigate security concerns.
Parental Controls

For parents or business owners, it's easy to set a schedule to control when children or employees are allowed to access the Internet. In addition, with built-in Google SafeSearch integration and a vast database of inappropriate websites, you can customize what kinds of content are permitted and effectively block thousands of sites with a few simple clicks. Having multiple customizable profiles allows for blocking different types of content for specific family members or employees.
Intelligent web filtering

Whereas traditional routers implement URL-based web filtering to block or allow specific content in the network, Synology Router Manager includes a more intelligent web filtering which checks if content is blocked or allowed during the DNS lookup stage of communication, making it harder to sneak through and see unauthorized content, while also reducing system resource consumption.

Protect your network

In addition to standard security tools like denial-of-service blocking and firewall management, Synology Router Manager delivers innovative tools to help protect your network from outside attacks.

Intrusion Prevention Beta

The Intrusion Prevention add-on package brings intrusion detection system (IDS) and intrusion prevention system (IPS) features to actively protect your network and devices from malicious parties. IDS analyzes traffic and detects intrusion within network, thus enhancing security rules to avoid future security problems. IPS inspects network packets in order to proactively prevent suspicious traffic and requests from entering your network.

Security Advisor

This handy diagnostics tool helps you optimize and understand security settings for your specific environment. By performing a comprehensive analysis of system settings, password strength, and network preferences, Security Advisor minimizes security holes and protects Synology Router RT1900ac — and your whole network.

QualysGuard Security Scan

Synology strives to guarantee a secure software experience for all users. With the help of QualysGuard, a trusted and market-leading vulnerability scanner, Synology can conduct thorough system scans and implement remediation. See security scan results

Take your files everywhere

By connecting an external storage device, Synology Router RT1900ac can become a private cloud server, allowing you to access files from anywhere, share photos with family and friends, or backup data from your Windows or Mac computers.

Browse and manage files

File Station is a handy file explorer for organizing and sharing files stored on storage devices connected to Synology Router RT1900ac. Upload files from a computer by simply dragging and dropping them into your browser, and then share with friends or coworkers by simply sending them a link.

Synchronize data across devices

Cloud Station lets you set up a private file syncing server, so you can synchronize documents, videos, or photos between Synology Router RT1900ac and other devices, like your computer or mobile devices. When you modify a file on one device, it is automatically updated on the other devices, allowing you to move between home and work, desktop and mobile, all while seamlessly working on the same file.

Back up personal computers

With the Cloud Station Backup application, you can easily back up files from your Windows, Mac, or Linux computers to a storage device connected to Synology Router RT1900ac. File version history saves up to 32 copies of each file, allowing you to go back in time and recover files that were overwritten or accidentally deleted.

Works with Time Machine

With support for Apple's Time Machine backup, Mac users can connect an external storage device to Synology Router RT1900ac and start backing up files from one or more Mac computers. Since the backup tasks are handled over the network, you skip the hassle of plugging in an external hard drive every time you want to back up data.

VPN support, RADIUS server, and other possibilities

Go beyond a simple router with a rich selection of add-on software packages available on Synology's Package Center. Transform your Synology Router RT1900ac into a personal VPN server, professional RADIUS authentication server, 24/7 download hub, multimedia library, or add other handy features for use at home or the office.
