When installing this VPN on your router, you may lose entry to the maximum of Surfshark capabilities that is available in its applications. Plus, you should have a router compatible with VPN; one that has a firmware with pre-setup OpenVPN or l2tp customer. I suggest the use of Surfshark VPN apps for your devices to get the most out of Surfshark. If you have a superior connection and network management then connecting with your device won't be an issue for you.
