How tech savvy do I need to be to use a Sabai VPN Router?

Not at all! Sabai Technology has customers from all walks of life, all over the world and at a huge range of ages, backgrounds and skill levels. Unlike routers flashed with dd-wrt or Tomato, there is no programming knowledge necessary to use a Sabai Router. If you have ever set up a router on your home network before, the process is very similar. Most customers can set up a Sabai VPN Router in about 5 minutes and very thorough instructions are included with every order. If you do get stuck, you can always connect to our Technical Support Staff and we will walk you through the process!

Regular router vs. VPN router, what is the difference?

Regular routers are very good at wirelessly connecting all of your network devices. If you have a VPN account, you can run it on your computer that is on this network, but you can not share that account connection with other devices on that network.

VPN Routers by Sabai, such as the Sabai Powered Netgear Nighthawk R7000, allow your VPN account to be run on the router itself, meaning you can run multiple network devices on the VPN simultaneously. For example, you can have a laptop in the kitchen streaming Pandora over VPN while your child is playing Xbox Live over VPN in the living room - all on a single VPN account. In many ways, it functions exactly the same way a regular router does except with added functionality that Sabai optimizes for the best VPN experience possible.

What is the difference between a Sabai OS Router and routers flashed with DD-WRT or Tomato?

Sabai OS, which comes pre-installed on all of our routers, has features not available on any other VPN client router operating system. Dual gateway, port forwarding and easy OpenVPN setup are specific to the Sabai operating system. The Sabai OS also has many settings already configured for VPN clients. A customer using dd-wrt or Tomato would have to figure out for themselves.

Another huge difference between Sabai Technology and our competitors is the technical and customer support peace of mind that comes with a Sabai purchase. A 90 day satisfaction guarantee and 1 YEAR of Sabai Freedom, our one-on-one technical support, come standard with every purchase. If you still need support after that time, you can always email or chat with us, or purchase Sabai Freedom for another year of the same phone and remote-in service that comes with your initial purchase. If you have any further questions, try watching one of our videos, reading our blog or contacting us at

Do I need to purchase one router for VPN and one for my local internet?

Not with Sabai Technology's custom operating system featuring Gateways! This unique feature lets you have complete control over which devices are on VPN and which are on local internet - all within a single router. Changing a device from local to VPN is easy with our easy to use interface, a change you can make as often as you like!

Will Sabai VPN Routers work in my location/country/area/situation?

Simply put, Sabai VPN Routers will work anywhere in the world. Sabai VPN Routers come with a standard American style plug and most models are dual voltage. We also sell a simple power plug adapter and a Universal Step Up / Step Down Power Converter on the website. Refer to each model's product description for more details. 

VPN Routers by Sabai support wireless B, G, B/G Mixed, N and AC devices and are available in 2.4 GHz , 5 GHz and dual band, effectively guaranteeing that they will work with any network device. You can read our Ultimate Router Comparison Guide HERE.

Port Forwarding for Foscam Wireless IP Camera

Setup port forwarding for VPN on the port that the camera is using. The Port forwarding is fairly straight forward, for example, when you access the port forwarding page it asks you for several pieces of information.

If you are using the VPN as Gateway then you will use the VPN public IP address followed by a colon and the external port you have used. If you are using the Local Gateway and have setup the camera on VPN then again use the VPN public IP address. However, if you have it set to local then use the Local IP address to access it. This of course is all from outside your network.

Speed Issues

Having issues with speed?  There are a few things you can try to resolve the problem on your own.

When you are experiencing a slow-down in your VPN speed, a number of things could be contributing factors.  We have noticed that older versions of certain web browsers can disrupt speed tests, so make sure that your internet browser is updated to the latest version. Check your Java to make sure it is also updated. Similar to the outdated web browser, if the updates on Java are not completed, speed tests can be affected.  Once you have verified that your programs are up-to-date, you can begin the speed tests.

Performing a few speed tests can help you find the fastest server for your location and help you understand what you can expect from your VPN.

Follow these simple steps:

  1. Disconnect from your VPN tunnel so you are on your local internet connection.  Once on your local connection, perform a Speed test on

  2. Next, click on the New Server button and drag the green square on the world map over to the location of the VPN server you are using (NY, San Francisco, London, etc.). Mouse over each dot until you find the correct city and click it to perform a speed test.  This will give you the best example of uninhibited internet access to that location. Your VPN will be slower than this speed because of encryption.

  3. You can repeat the test to different server locations that are included in your VPN plan and use the one that gives you the best speed. Once you have determined which is best, log onto your VPN account and switch to a server in that area.

  4. Enter the new server information into your Sabai Router by following the instructions included with your shipment.

If you are unable to resolve you speed issues with these tests, contact us at

Advanced speed troubleshooting

For optimal VPN speeds, one common adjustment is MTU or Maximum Transmission Unit. Adjusting this setting on your computer, VPN Router, or OpenVPN script, allows more bytes of data through that protocol layer. While this may seem intimidating, the basic troubleshooting for MTU is relatively simple.

Finding your MTU Settings

Visit to determine what defaults your MTU and MSS are set at. If your MTU is less than 1500 see below, Changing MTU on your Sabai Router. If your MSS is less than 1400, and you are on OpenVPN, try Changing MSS on your OpenVPN script as well.

Note: If you are on DSL with PPPoE, your maximum MTU is 1492. If you use PPTP, you can not change your MSS.

Changing MTU on your Sabai Router

On your Sabai VPN Router, visit the network page.

In the first drop down next to MTU, change from default to manual. This will allow you to manually change the second field to 1500, the largest allowed by Ethernet. Click Save.

Changing MSS on your OpenVPN Script

If you use StrongVPN as your VPN provider, changing your MSS on your OpenVPN script is simple. If you use another VPN service, please check with that provider’s technical support to ask how to make this change or look for it under advanced options. Not all providers allow MSS changes.

While logged into your account, look for the MSS & Fragment link under Special Actions. Change the MSS setting to 1300, save and export a new script for your VPN Router.

These setting changes will solve most, but not all, MTU lag issues. However, there are many articles available that include more advanced troubleshooting. If you still aren’t happy with your speed, get in touch with our technical support.

Wireless connection for Mac

If your Mac frequently disconnects from your wireless network, follow these steps:

  1. Go to Apple Menu on the upper left-hand corner of the screen. Select System Preferences>Network Icon.

  2. In the dialog box, Click on the Advanced tab in the lower right-hand corner. Drag your network entry to the top of the list (It may take a few tries to grab and move to the top of the list.)

  3. Click Apply Now and shut down the computer.

  4. Next, restart the computer and zap the PRAM (Clearing the PRAM helps with any corruption that may have occurred).

  5. To zap the PRAM, hold down the Command (?), Option, P, and R keys simultaneously immediately after re-starting the system. You must do this before the gray screen appears. Don’t let go of the keys until you hear the startup sound for the second time.

If this does not solve the problem, please contact us at

How to reboot the VPN Accelerator

If you experience issues with your VPN Accelerator, the first thing to do is reboot. If you need to do so, follow these instructions:

  1. Turn off the VPN Accelerator (press the power button, do not unplug)
  2. Set the Sabai router Gateways default to None
  3. Reboot the router
  4. Restart the VPN Accelerator, check that the VPN has connected
  5. Set the Sabai router Gateways default back to your choice
