Asus RT-AC66U VPN Router Setup

At Sabai Technology, we are committed to customer service. The Sabai VPN Router setup is created with beginners in mind and Technical Support is available for customers who need assistance. Plug and play style, Sabai OS is particularly easy when compared with DIY options such as DD-WRT.

Getting started

To set up your Sabai OS powered Asus RT-AC66U router:

  1. Unplug your modem from the power supply

  2. Connect your router to the modem via ethernet cable

  3. Plug in your Asus RT-AC66U router and modem to the power socket

  4. Start up the modem and router

  5. Open your web browser and type into the address bar:

  6. Enter the password that came with your router

Now you’re at the Sabai OS home screen, use our router setup guide to finish setting.


Sabai Technology's most unique and popular advanced networking feature is Gateways. This feature provides a list of all the devices on your network, and allows you to designate whether they should use your local IP address, your VPN IP address, and/or your VPN Accelerator IP address. (What is the VPN Accelerator?) All of this control from one single router connection can only come from Sabai.

Multiple wireless networks in one home can slow down both connections. Everyone knows that when it comes to VPN, speed is crucial - especially if the main goal of your VPN account is entertainment! Gateways means that your laptop can be on local internet and your Smart TV on VPN to the UK or US, every time you boot up. No interference. No switching networks.


Asus RT-AC66U optimized by Sabai OS

Even though the Sabai Technology Asus RT-AC66U router looks the same as the basic model purchased elsewhere, we have installed our special operating system, designed to run a VPN account.

<strong>Sabai Technology has developed a firmware that works seamlessly with OpenVPN and PPTP, the most popular VPN protocols.</strong>

Typically, VPN only works on a single VPN enabled device. A "normal" or "off the shelf" router isn't VPN enabled, even if it says it allows VPN pass-thru. This 'pass-thru' feature only means that if you are running VPN on your computer but are connected to the internet via wireless, it will still work. It is only when you use your VPN account on a Sabai VPN Router that you can actually broadcast your VPN IP address to your entire home network.

Why choose a Sabai VPN router

By now you may be thinking - “Why do I need a VPN router, what’s the problem with just having a VPN on my laptop?”

Well, it’s great that you take your privacy seriously, but by having a simple VPN setup on your laptop, you’re missing out on so much!

For example - with a Sabai VPN router, you can create gateways that allow different devices on your network to connect to either local internet OR VPN. This means your laptop and phone could be using your regular IP from your internet provider, whilst your TV uses a VPN to connect to a server in another country to unblock content!

There’s more,

Sabai OS has been independently tested against stock firmware, DD-WRT, and Tomato, and was found be the fastest operating system for VPN enabled routers. Add to this Sabai Technology’s industry leading support, and you have a VPN router that hands down beats anything else on the market.

    Works as advertised!

    First class router and with the new sabai OS you cannot go wrong.
    I have been using this for years and it has never failed.

    The range is good even for a multi level home.
    A couple of things to look out for. It gets warm and click the power button gently. This is an Asus design issue.

    I recommend you get the vpna for the best home network setup.

    The Sabai team are always quick and ready to help. They have never not known how to help me.

    Alternatives? I really don't see any that compare to Sabai.
