Compared to your existing router, a FlashRouter will tunnel all your traffic through a secure CyberGhost VPN server of your choosing. And while you can still install CyberGhost VPN on your already existing router, a router that comes with the app already installed has several benefits. The most important of which being that you don’t have to go through the painstaking setup process. Plus, FlashRouters are new models that may enhance data transfer speeds across your home network or extend the range of your Wireless signal.
