Synology RT1900ac review: Synology brings its NAS expertise to routers

Price when reviewed

Synology produces some of the best NAS devices around, but the RT1900ac is the company’s first attempt at a wireless router. Looking at the specification sheet, there doesn’t seem to be much to separate it from the competition: it’s a 3×3-MIMO-stream, simultaneous-dual-band router, with a maximum 1,300Mbits/sec link speed over 802.11ac and beamforming support. However, it’s the user interface that sets the RT1900ac apart from its rivals.

Synology RT1900ac review: Synology brings its NAS expertise to routers

Synology has taken the familiar DiskStation Manager (DSM) interface from its NAS range and reimagined it as Synology Router Manager (SRM). They’re very similar, so Synology NAS owners will feel right at home. The web interface feels like a desktop OS, with separate windows and shortcuts to settings and features.

Synology RT1900ac: Features

All the crucial network settings are ordered sensibly in the Network Center app, with a networkmap showing which devices are currently connected and a traffic control page allowing you to give priority to specific devices. The grid-based parental-control scheduler is fantastic, letting you quickly drag and select blocks of time to limit access to certain websites.

Even the initial setup is straightforward, with a quick guide walking you through each step. It also forces you to create a unique username and password, which should boost security; many of the routers in this Labs default to admin/ admin and don’t prompt you to change them when you first log in.

This simplicity belies a wealth of options to keep network administrators happy, including upload/download limitations per service or application, QoS prioritisation, dual guest Wi-Fi networks and VPN access. The dual-core, 1GHz processor, 4GB of flash storage and 256MB of RAM keep the interface ticking over smoothly, even when you have multiple windows open at once.

A package manager lets you download additional services and features, with many transitioning from DSM. Download Station, Audio Station, Photo Station and Video Station are all present and correct, letting you access multimedia files or queue up torrent files remotely using smartphone companion apps and Synology’s QuickConnect dynamic DNS service.

With an SD card reader in addition to a USB 3 port, you could add 128GB of flash storage and not need to make room for an external hard disk next to the router. (Don’t expect blistering speeds, though: USB 3 file-transfer performance was merely respectable, at 53.7MB/sec.) The port can also be used with 3G/4G mobile broadband dongles as a backup, in case your primary connection fails. A dedicated DS Router app is also available for Android and iOS for applying parental controls, checking the number of connected devices and tweaking firewall rules.

The RT1900ac features a number of neat touches, such as the ability to schedule when the activity LEDs on the front of the unit are switched on: turning them off between midnight and 7am could help you get to sleep if the router is located in a bedroom, but they’ll be on during the day for troubleshooting.

There’s little on the outside to indicate the software excellence within; the RT1900ac is diminutive. The two feet on the back help elevate the unit to keep it cool, but otherwise it’s a nondescript black box. The four Gigabit LAN ports and single Gigabit WAN port are par for the course, as are the three removable, adjustable antennae that let you fine-tune the coverage of your wireless network.

Synology RT1900ac: Performance and Verdict

Wireless performance was very good at close range, with 78MB/sec over 802.11ac narrowly falling behind the Asus RT-AC3200 but besting all the ISP-supplied routers. Over 5GHz 802.11n, 16.6MB/sec is approaching the top end of a 2×2-stream device’s capabilities; other routers are faster, but not by much.

Moving to long range, 802.11ac performance was consistent, with 27.8MB/sec falling only just behind the fastest models on test. A 5GHz 802.11n result of just 9.2MB/sec is slightly below average, however.

With such a strong set of performance figures coupled to an amazing price, the RT1900ac would stand up on its own even without Synology’s fantastic user interface. SRM makes all the difference: it’s responsive, user-friendly without excluding advanced features, and unbelievably flexible. It’s better than any other router UI we’ve used before and sets the gold standard for the competition in future.
