The Synology Router RT1900ac is Synology’s first router. It is targeted at the mid-range router market and hence it’s retail price is S$234 US$149 (S$210). It started selling in Singapore on 6th October 2015. I will update this post again when I have the actual retail price in Singapore rather than using the currency conversion from the official retail price in USD.

Synology Router RT1900ac Review Cazhxj11

For the unaware, Synology makes one of the best NAS in the market especially for the prosumer market. I personally owned three Synology NASes, DS210j, DS413j and DS415play.

Synology creates network attached storage, IP surveillance solutions, and network equipment that transform the way users manage data, conduct surveillance, and manage network in the cloud era. By taking full advantage of the latest technologies, Synology aims to help users centralize data storage and backup, share files on-the-go, implement professional surveillance solutions, and manage network in reliable and affordable ways. Synology is committed to delivering products with forward-thinking features and the best in class customer services.

Design

The router is compact and lightweight. The design is pretty simple with a huge Synology logo on the top and LED indicators in front.

The router case is well ventilated with holes pretty much on every side except the top.

You can place the router in two ways, either flat down on a surface or standing up using the included stand. I prefer the router to be standing so it takes up less space.

Ports

This is the first router that I encountered that has a SD card slot. The SD card slot is compatible with SDXC cards up to 2TB.

I like the way the ports and buttons on this router are organised.

At the back, you have the power button, power port, 1x WAN port followed by 4x LAN ports.

Setting Up

After plugging in the router, you can access the router admin UI via http://router.synology.com which resolves to http://192.168.1.1 and that will guide you through the set up process. There are about 4 steps in total.

Admin UI

Perhaps my favourite thing about Synology hardware is the awesome (and fast) UI. For NASes, Synology uses the Synology DiskStation Manager (DSM). And for routers, it is called Synology Router Manager (SRM).

I would like to think that the SRM is a subset of the DSM. If you are not a Synology DSM user before, don’t worry, the UI for SRM is pretty straight forward.

After setting up the router, you will get to launch the SRM for the first time. You will be given a tutorial walkthrough on the UI. I think this is the first router to do that after using routers from Linksys, D-Link and Asus.

Here are some screenshots for the common features like Port Forward, Port Triggering, Static Routes, DDNS, etc.

Mobile App

There is a DS Router app on Apple App Store as well as Google Play.
You can use the DS Router app to setup your router as well as manage it. I am not really a fan of using an app to setup or manage a router.

Furthermore, SRM is already an awesome admin interface, I don’t see the need of using an app to manage this router.

Package Center

You can easily install applications to the SRM using the package center.

Synology Router RT1900ac – Package Center

Despite having a 4GB flash storage in the router, you cannot use the built-in storage to install applications. You will need to plug in your own USB flash drive or SD card in order to install them.

Synology Router RT1900ac Review 23667228946_177b4da63f_c
Synology Router RT1900ac – Storage

As of writing, there are only five packages available: Download Station, Media Server, VPN Server, DNS Server and RADIUS server. I hope eventually there will be more packages.

For most people, you will probably just need Download Station and Media Server.

Download Station allows you to download files from the Internet through BitTorrent, FTP, HTTP, NZB, Thunder, FlashGet, QQDL, and eMule.

Synology Router RT1900ac Review 23610835031_e5569194a2_c
Synology Router RT1900ac – Download Station

Media Server on the other hand allows you to stream media that you have downloaded to DLNA/UPnP-compliant devices.
I wish they is a Plex app as well like they do on their NASes.

On my DS415play, I use Download Station to download content, File Station (built-in app) to move it to the correct folder and Plex app to stream the content to my devices from the folder.

VPN Client/Server

The router supports both VPN Client and VPN Server. VPN Client support is built-in, to use the router as a VPN Server, you need to visit the Package Center and download the VPN Server Package.

Synology Router RT1900ac Review 23325365789_025c9df8db_c
Synology Router RT1900ac – VPN Client

I tried using it as a VPN Client with my VyprVPN account and it works fine.

If you are a VyprVPN customer, you can refer to this guide. You will just need to key in your email, password, which VPN server to connect to and upload the certificate which you can download from the link in the guide.

VLAN Tagging

A very unfortunate thing about this router is the lack of VLAN Tagging. In Singapore, you pretty much need VLAN Tagging if you are on Singtel or Starhub. So the lack of VLAN Tagging means you can’t use this router directly with the Optical Network Terminal (ONT).

I really hope in future software update, this will be included. VLAN Tagging support will be released next month (January 2016) via a software update according to Synology.

Wireless Strength

I am using the WiFi Explorer app on my MacBook Pro to test the wireless strength of two extreme corners of my house, my room and the common toilet.

Summary

Both the wireless speed and coverage of this router is average. But given the price, I think it is still acceptable.
The current lack of VLAN tagging is pretty disappointing but I am glad VLAN tagging support will be coming via a software update next month (January 2016).

What I love about this router is the admin UI, I have never seen a router with such a nice and fast UI. I have to admit, I am a fanboy of Synology admin UI.

Would you recommend this router? I would say it depends. If you use your router as a mini-computer to download and stream content, this router is definitely for you because the Package Center has potential to turn the router into a mini-computer that does a lot of things. Whereas if you just use your router as a router and nothing else, you probably be better off with a high-end router like the ASUS RT-AC88U where it has much more features like eight LAN ports and Dual-WAN.

Afterall, this is Synology first router which is targeted at the mid-market. I am sure they will come out with another router that targets the high-end market next year and I am looking forward to that.

Pros:

  • Excellent admin UI
  • VPN server & VPN client support
  • Reasonably priced


Cons:

  • Average wireless speed/coverage
  • No VLAN Tagging yet (TBA January 2016)


*UPDATE 18th January 2016* VLAN tagging has been released for the router on the 12th January 2016. The firmware version is 1.0.1-6007. Check out RT1900ac Release Notes for more information and Toolset.

Synology – get DNS and DHCP to work by SSH

- Synology Router RT1900ac High-Speed Wireless Router Review
- Synology RT1900ac Wi-Fi Router: Australian Review

Synology Router RT1900ac Review 15100111


Setup Synology DNS and DHCP

I thought it should be easy. Been using DNS as backup DNS for a long time without problems and recently wanted to use my NAS as DHCP instead some other means of mine.

You might want to take a look at my post on installing the Config Editor so you don’t have to use an SSH client.

DHCP server didn’t hand out IPs though, so the hunt was on.

I found I needed to generate two files using SSH as root:

– touch command basically generates empty files in the location and name specified.

touch /var/packages/DHCPServer/target/etc/dhcpd.conf.leases
touch /var/packages/DHCPServer/target/etc/dhcpd-leases.log


and restart networking

/etc/rc.network

restart or if you are in /etc/

./rc.Network restart

After the above I still had no luck getting client IPs and I found the following error messages displayed in /var/log/messages

Dec 15 06:03:00 NAS dnsmasq[12770]: ignoring nameserver 192.168.1.10 - local interface

Dec 15 06:03:01 NAS dnsmasq[12894]: warning: interface dns does not currently exist

Fixing dhcpd.conf

In /etc/dhcpd/dhcpd.conf I had to change all localhost IPs to the correct ones. Be it DNS, router and DHCP scope respectively.

Mine were looking like this:

interface=bond0
dhcp-range=set:bond00,192.168.1.50,192.168.1.100,255.255.255.0,36000
dhcp-option=tag:bond00,option:router,127.0.0.1
dhcp-option=tag:bond00,option:dns-server,192.168.1.10,192.168.1.205

dhcp-host=00:25:84:41:e7:58,asa5505.dintid.dk,192.168.1.1,infinite


And it should look like this

interface=bond0
dhcp-range=set:bond00,192.168.1.50,192.168.1.100,255.255.255.0,36000

interface=dns

dhcp-host=00:25:84:41:e7:58,asa5505.dintid.dk,192.168.1.1,infinite


Fixing dhcpd-dns-dns.conf

In /etc/dhcpd/dhcpd-dns-dns.conf I had to change all localhost IPs to the correct DNS, Router and DHCP  respectively.

Mine were looking like this:

port=0
interface=dns
dhcp-range=set:dns,127.0.0.1,127.0.0.1,255.255.255.0,86400


And it should look like this:

dhcp-option=tag:dns,option:dns-server,192.168.1.10
dhcp-option=tag:dns,option:router,192.168.1.1
port=0
interface=dns
dhcp-range=set:dns,192.168.1.50,192.168.1.100,255.255.255.0,86400

Synology RT1900ac Router Inside

Analysis by Tim Higgins

Although the RT1900ac is Broadcom based, pairing a BCM58622 ARM cortex A9 processor with embedded Gigabit switch with two BCM43460 radios. Other popular Broadcom-based AC1900 class routers use either the BCM4708A or BCM4709A processors paired with BCM4360 radios. Of significant note is the 4 GB of flash found in the RT1900ac,compared to the 128 MB in most other AC1900 class routers.

There are two versions of the board. US customers will most likely get the R1 version that recently appeared in the FCC ID database. The images below show the different board versions; version 1.3 for the original board and version 1.7 for R1. While they are very similar, the R1 board has shielding tape added. You'll also note the coaxial cables for the center and right antennas have been rerouted away from what appears to be the CPU in the center of the board.

Synology Router RT1900ac Review Synolo10

Synology RT1900ac original board

The R1 board also eliminates the tape on the two coaxial cables and instead, routes all cables through a single clip on the upper left side of the board.

Synology Router RT1900ac Review Synolo11

Synology RT1900ac R1 board

After testing was done, we opened the router and popped the tops of the RF cans to identify the other radio components. Here's a shot of the R1 board with the radio can tops off. When we took the big heatsink off that sits on all the RF cans, we found only two small thermal pads coupling the heatsink to the top of the processor and top of the 2.4 GHz radio.

There were also no thermal pads on the inside of the RF can tops to thermally tie the BCM43460 radio SoCs to the can tops. The thermal design definitely could use some improvement.

Synology Router RT1900ac High-Speed Wireless Router Review- A Closer Look

It is time to take a closer look at the Synology Router RT1900ac and the first thing that we haven’t seen close up on the first page are the available LEDs. There is one for each wired and wireless connection as well as a status one. A full set.

The eject button also features a multi-coloured LED to show the status of attached devices.

The bottom of the router has mounting holes in the middle that can be used for the included stand or to wall mount it. The two feet seen at the top of this image can easily be removed should you wish an even flatter design, they’re just attached with the one screw each which can be placed back into the router once the foot has been removed. The middle features a sticker with the relevant information such as default router settings, MAC address, and serial number. We can also spot the reset hole at the top of the photo.

We find a PCB that is fully occupying the space inside the chassis once we open the RT1900ac up. This is naturally not something you should do yourself. The first thing that springs into the eye is the large passive heatsink placed over most of the motherboard. A size like this should ensure proper cooling for the CPU, RAM, and other parts soldered underneath.

The rear of the PCB doesn’t feature much besides a few chips and a switch.

You can see a few close-up shots of some of the features below and there really isn’t that much to say to it. Buttons, switches, and ports.

Dear Customer,

Thank you for contacting Synology. We will get back to you as soon as possible. Thanks for your patience.
Below is a copy of your message that we've just received from you.

Problem Explanation:I want to set up guest wireless network to connect also features smart connect.
Setup Time for Guest network is very good feature, but I want to be able to reduce the time or unlimited instead of only an hour plus button now.
Plus, I do not know the product s/n router somewhere in the WEB management. Thankfully I was shell router box. 15AON3N931100 or 15A0N3N931100 is OK.
Finally, I'd love to know the commands can be used with this operating system on the router. For example, I can turn off wifi, set dhcp via ssh protocol.
