Plug and Play VPN Support
Yes you can!
To receive a plug and play with VPN device, you will need to provide our team with the credentials from your VPN provider subscription.
To have your router VPN preconfigured:
Privacy Hero 2 Only:
While our team isn’t able to pre-configure the Privacy Hero 2 VPN Router before shipping it out since you’ll have to make a Privacy Hero user account and register your router, we can assist you with the VPN set up process once you receive the router and create your Privacy Hero user account via 1-on-1 remote session, email, or live chat on our site.
You can also use our step-by-step Privacy Hero VPN Router Setup Guide to complete the process.
Dedicated IP Addresses from NordVPN, SurfShark, & TorGuard are supported on almost all of our FlashRouter options.
Check out our Dedicated IP Addresses Blog Post for more details!
Yes!
You will be able to connect the FlashRouter of your choosing to your current mesh router via ethernet port as shown below:
ISP Modem/Router —- FlashRouter (VPN) —- Main Mesh Router (VPN from FlashRouter)
This setup will allow you to keep your mesh network with added VPN protection, as well as add the FlashRouter wireless network for your devices.
You can disable the wifi on the FlashRouter also if you only wanted to use the mesh network for wifi.
At FlashRouters, we offer expert router flashing and VPN configuration services through our Flash My Router plans. Whether your router needs custom firmware flashing or just a VPN configuration, we ensure it’s set up for maximum security, privacy, and streaming performance with your chosen VPN provider.
The appointment will take place via remote software. During the appointment, our team will also answer any questions you may have about using the VPN on the router. Flashing is done out of the East Coast of the United States – we will do our best to accommodate your time zone difference if you are located in another part of the United States or another country.

✅ Flashing vs. Configuration: Some routers require custom firmware (flashing) to enable VPN, while others can be configured without flashing.
✅ Fully Optimized: Our team ensures your router is ready to securely connect to your VPN, block ISP tracking, and enhance your streaming experience.
✅ Remote Assistance Available: Get expert help setting up your VPN connection remotely if needed.
At FlashRouters, we handle VPN setup differently based on your router brand and model. Some routers require flashing custom firmware (like DD-WRT or AsusWRT-Merlin), while others can be configured without flashing.
These routers require firmware flashing (DD-WRT or AsusWRT-Merlin) to enable VPN compatibility.
These routers have built-in VPN support and only require proper setup.
📌 Other brands are not supported at this time. If you have a different router, we recommend checking out our pre-flashed router options.
We work with a wide range of VPN providers, including:
(If your provider isn’t listed, reach out – we may still be able to support it!)

US Customers (Single Router Solution):
Almost all Internet Service Providers(ISPs) require a modem in place to establish a connection to their service, however a modem by itself doesn’t provide the wifi connectivity needed in the home or office. A FlashRouter can connect directly to all known modems provided by major ISPs to create a wireless network so long as there is an Ethernet port on the modem to connect to the FlashRouter Internet port.
US Customers (Dual Router Solution):
Yes, FlashRouters are compatible with your ISP in what is called a Dual Router Set Up.
For this type of setup, you would use your current router or modem router to connect to your local ISP while using a FlashRouter to connect to your VPN. This is recommended as you will not overhaul your network with a new router, and you will be able to use your selected VPN service on the devices you wish to use it with.
This set up would result in the creation of two networks, which can be seen as the “Local Network” and the “FlashRouter Network”. All devices connected to the FlashRouter Network will go through the VPN service.
For any device you would prefer to use without a VPN, you can connect to the local network. The chain of devices would be connected from LAN ton your modem or modem/router to WAN on the FlashRouter, with your current router connected to the FlashRouter via Ethernet cable.
International Customers (Single Router Solution):

ISPs should all be compatible. Some providers require VLAN tagging/VID settings when wiring directly from modem to FlashRouter.

Open Source firmware like DD-WRT or Assu Merlin has many features equivalent to what stock firmware has, in addition to adding new features to a router. However, some features are lost from the stock firmware when a router is flashed.
These are typically features that are put into the stock firmware by the manufacturers themselves. Things like the Linksys App and the NetGear Genie are examples of what would not be available or compatible on the router after flashing.
Most routers also have a WPS button. By default, the WPS button’s functionality is disabled when a router is flashed as it can be vulnerable and a security risk. It can be re-enabled by following this guide but we do not recommend it.
A subscription to a VPN does not come with a FlashRouter or Service plan. If you are planning to use a VPN, you would need to sign up for one separately, directly from a provider.

Plug and Play VPN Support
Unlike other VPN Router providers, FlashRouters is proud to offer free VPN service integration with any purchase.
To receive a plug and play with VPN device, you will need to provide our team with the credentials from your VPN provider subscription.
To have your router VPN pre-configured:
Please note: If you do not enter a server location request in “Order Comments”, we will automatically start the device with the closest/optimal server for the location we are shipping the device by default. A location has to be added to the initial configuration for plug and play encryption security to occur on the device.
Yes! A large number of our customers use their FlashRouters to “work from home” no matter where your travels take you. Check out our Working Remotely Blog Post for more details.
Location: VPN Services offer many server locations to encrypt your traffic through. They are located in several countries worldwide for creating a private VPN tunnel for your online activities. A business VPN connects to specific central servers for data or directly to your office, creating a direct tunnel for accessing sensitive work documents and information.
Logging: Most VPN services offer log-free connections for total anonymity and security when connected (it is important to check out their terms of service and privacy policy for full details). A business VPN is monitored and maintained by employers such as corporations, hospitals or universities.
Protection: VPN services secure your family’s personal data while using computers, SmartTVs and various Internet of Things devices. Business VPNs protect the data of the company while you are tunneling into work.
There are in fact several trusted VPN providers that have services specially tailored for business use. NordVPN Teams and VyprVPN for Business offer a full suite of solutions like user management tools, dedicated IPs, personal product managers, global server access, business pricing, and more.
These solutions allow you to quickly deploy a safe and secure corporate network without building and maintaining your own servers. If you are a small business looking to quickly secure remote workers as they shift to work from home, and you do not have an in-house IT expert, then you should consider NordVPN Teams or VyprVPN for Business.
Even better, when choosing a business VPN provider like NordVPN or VyprVPN, employees can use routers with direct NordVPN and VyprVPN integration already included through the FR Privacy App. Meaning that a full network kill switch, routing by device, automatic connections, and more are all included as features with your business VPN connection.
Many of our customers have found that they can connect to both their corporate and personal VPN, however due to the variables beyond our control, we cannot guarantee this for every unique situation.
Using two VPNs at once can lead to unpredictable results. Bouncing your network traffic to multiple servers before finally arriving at it’s intended destination can sometimes introduce speed and connection issues.
Please consider that some employers and agencies are more vigilant regarding third party VPN use than others. There are tools readily available that detect the use of VPN services.
While these tools cannot decrypt and view your network traffic, they can tell your employer that you are potentially using a VPN, which can be against company policy.
If your corporate and personal VPN do not work together, then you can always set the computer using your work VPN to bypass the FlashRouter’s VPN tunnel by accessing the router admin panel for your device.
This way, your computer would only use the work VPN. Keep in mind however, your location would appear as your actual location to your work.
Every FlashRouter also comes with a 30 Day Satisfaction Guarantee.
If in the event you determine the FlashRouter is not working out for you, you can return the device within the first 30 Days. A $25 restocking fee does apply.
Of course! If you have an OpenVPN server running on a local machine or hosted on a cloud provider like Amazon Web Services (AWS), FlashRouters can create a custom router client configuration to connect the entire router and all connected devices to your OpenVPN server. Instead of employees connecting device-by-device, a router-based VPN connection allows for always-on secure VPN tunneling.
Our service team is here to work with you to test and ensure compatibility before purchasing. Interested in a router based custom client VPN solution for your remote workers? Please do not hesitate to contact us.

All FlashRouters are compatible with all ISP service types such as fiber, cable, DSL, and satellite. As long as you have a modem, modem/router, or router capable of an ethernet connection your FlashRouter will have no problems connecting to the internet.
Internet Service Providers (ISP) include a modem or modem/router combo to connect your network devices to the internet. In some instances your ISP will provide a separate router as well as the modem. You can replace this router with a FlashRouter or use both in a dual router setup.
If you would like to replace your outdated router or avoid paying to rent a router from your ISP then you should use a FlashRouter as the only WiFi device in your network.
In a single router setup the FlashRouter will be wired directly to your modem via ethernet cable and will be the only router in the setup.
Wire an ethernet cable from an open ethernet port on your modem to the WAN/internet port of the FlashRouter.

On Asus FlashRouters the WAN/internet port will be blue.

On Linksys FlashRouters the WAN/internet port will be yellow.

On Netgear FlashRouters the WAN/internet port will be yellow.

Once you have properly connected an ethernet cable from your modem into the FlashRouter internet port you must power cycle your network devices to establish an internet connection.
If you would like to keep your existing WiFi network in place, and simply want to add in a VPN WiFi network with a FlashRouter then you can do so using a dual router setup. No settings in your existing network router need to change to add a FlashRouter in a dual router setup. Since we preset all FlashRouters to a unique Local IP Address, there won’t be a conflict with your existing router.
In a dual router setup the FlashRouter is wired to your existing router via ethernet cable and you will have two completely segmented WiFi networks available.
Remember if your existing router is connecting to the internet without issue already, make sure to keep the ethernet cable between your modem and existing router internet port in place.
Now connect another ethernet cable from a LAN/numbered port on your existing router to the WAN/internet port of the FlashRouter.
Reference the images above to see your WAN/internet port color.

Once you have properly connected an ethernet cable from your existing router into the FlashRouter internet port you must power cycle your network devices to establish an internet connection.
Once the power cycling steps are complete and the FlashRouter is powered up, start connecting your internet capable devices via ethernet or WiFi. Visit any website and make sure the page fully loads.

Our routers are priced for the custom upgrades performed at our warehouse, testing expenses and keeping the FlashRouter App update to date.
Our service plan has three levels as an optional add-on with your purchase to get continued direct assistance from our team. This is especially useful to customers who are less tech savvy and want direct access to our support team to make sure their network is running exactly how they desire. Here is how these plans differ
Bronze – Basic E-mail Support
Silver – E-mail and Live Chat Support.
Gold – E-mail, Live Chat, and Remote One-on-One Sessions
Each situation and user has different needs and expertise. Our team of US-based support agents are highly trained specialists in VPN and DD-WRT router setup. From firmware updates to networking configuration/troubleshooting,solutions, the purpose of our Service Plans is to help our customers in whatever level they deem necessary.
At this time, we do not provide phone support with our service plans. We have tested phone support for networking troubleshooting in the past but have found that on average caused us to help less customers in a less efficient manner. However, with a purchase of a Gold Service Plan, customers can schedule 1-on-1 remote support sessions via Teamviewer with our engineers and they will provide a hands-on, personal solution, to any problems you may be facing.
Firmware upgrades are free of charge to any FlashRouter customer!
You can visit our support center and select your specific router model to upgrade your firmware based on the recommendations provided.
If you want the help of our Support Team to assist in this upgrade, you can always sign up for our Gold Service Plan and schedule a 1-on-1 Teamviewer session in which our trained engineers will take care of the upgrade for you!
Our complimentary 1-year hardware warranty does not include tech support outside. If your router suffers hardware failure within 365 days from the date you received the unit, then we will gladly replace your router with another fully tested one. For more information regarding our warranty and return policy, please check out our warranty and return section.
Yes, you may purchase a service plan at any time. However, we can’t guarantee any pricing, or apply any previously offered discounts or specific features at that later date.
