Note - Make sure that the router IP of your VPN router is on a different subnet than your main router. For example, my main router IP is 192.168.1.1. By default, the ExpressVPN router app firmware assigned itself the IP address 192.168.22.1, which is fine. If you are using another firmware such as Tomato, DD-WRT, OpenWRT, Merlin, etc then you will likely need to change the default gateway IP from 192.168.1.1 to 192.168.x.1, where x is a number between 1 and 255 that is different from any other routers or gateways in your network.





How to flash the ExpressVPN firmware





Step 1 - Sign up for ExpressVPN if you don't already have an account. There is a 30 day money back guarantee on all plans, so you can try it risk-free.

Step 2 - Download the ExpressVPN router app firmware from device set-up page on the ExpressVPN website (there is a direct link in your confirmation email).





Step 3 - Connect the EA6200/XAC1200 to your computer by LAN cable from any one of LAN ports on the router to the LAN port on your computer. Do not flash firmware using Wi-Fi.





Step 4 - Disable your Wi-Fi adapter and make sure that your Ethernet adapter is enabled. To open the network adapters in Windows 7/8/10, you can press Win key + R and then type "ncpa.cpl" (without quotes) in the run dialog.





Step 5 - Enter 192.168.1.1 in your web browser.





Step 6 - Enable both of the 2 options:





"I have read and accepted the License Terms for using this software"





"I want to skip setup and configure my router manually"





Then, click "Next" button.





Step 7 - When you get the message "Internet connection is down", press the "Login" button on the bottom right.





Step 8 - Enter the default password "admin" (without quotes) and and then click "Sign in".





Note - Other models of Linksys routers have different default passwords. For example, my WRT1900ACS has a unique default password that is printed on the label of the router.





Step 9 - Under the heading "Router Settings" on the left, click on "Connectivity."





Step 10 - Under the text "Router Firmware Update" on the right side, find the second box below it with the text "Manual". Click the "Choose File" button and then select the file that you downloaded in step 2.





Step 11 - After the file is selected, click the "Start" button to start flashing the firmware. Press "Yes" to continue when asked. Wait for the message that your router will reboot and press "Ok".





Step 12 - Wait for the ExpressVPN router interface to load. This should happen automatically within a few minutes of your router rebooting. If this doesn't happen, then you can enter http://expressvpnrouter.com in your browser.





Step 13 - Login with the same default password of "admin" and then choose "Enable internet without VPN".





Step 14 - Set your desired Wi-Fi and other router settings. Change the SSID (Wi-Fi network name) for the 5Ghz and 2.4Ghz channels, set the Wi-Fi passwords, change the default router password from "admin" to something else, etc.





Step 15 - Open your network adapters again and enable your Wi-Fi adapter and then connect to the router by Wi-Fi to confirm that you can connect (you will still not have access to the internet yet, just confirm that you can make the connection by Wi-Fi).





Step 16 - Connect the router to your main router as shown in the diagram near the top of this page (connect LAN cable from any spare LAN port on your main router to the Internet / WAN port of the VPN router).





Step 17 - Now your VPN router has an internet connection (from your main router). You can now log into the interface again at http://expressvpnrouter.com and paste your activation code from your account set-up page (the page where you downloaded the firmware in step 2).





Step 18 - After you have activated, the router should connect automatically to a "recommend" location. You can change this to your desired server location and change the VPN protocol between UDP and TCP if desired.





Step 19 - Connect your devices to your new VPN Wi-Fi network (or connect by LAN cable to the VPN router) and enjoy VPN on all devices without running any VPN apps.
