A VPN app protects one device while it is connected. A VPN client running on the router can send every home device through the VPN automatically, including TVs and consoles that cannot install VPN apps.
Does this affect you?
Use this if you are deciding between installing VPN apps device by device or configuring VPN client mode on a home router.
Check router support first
VPN server and VPN client are different features.
- Log into the router and look for VPN or Advanced > VPN Client.
- Confirm it supports VPN client mode, meaning the router connects out to a VPN provider. ASUS routers commonly support this; many Netgear and Linksys routers only provide VPN server mode for remote access into home.
- If no client mode exists, check whether the model supports DD-WRT or OpenWrt. This can add VPN client support but may void warranties and is not beginner-friendly.
- If neither option fits, consider a dedicated VPN router or travel router as a secondary network.
Turn it on when supported
Use the VPN provider router instructions.
- Sign up for a VPN service that provides router configuration files.
- Open the router VPN Client settings.
- Choose the recommended protocol, often WireGuard or OpenVPN.
- Enter credentials or upload the configuration file.
- Save and activate the connection.
- From a connected device, check your public IP address and confirm it shows the VPN server location.
More control
The benefit is automatic coverage
Smart TVs, game consoles, streaming boxes, and smart hubs all use the VPN without installing apps. You manage one setting instead of many.
The cost is shared speed and less flexibility
All devices share one VPN tunnel. A slow server slows the whole house, and router-wide VPNs usually cannot exclude one app the way device apps can.
A secondary VPN router can split traffic
A travel router or VPN-only router creates a second Wi-Fi network. Devices that need VPN join it, while everything else stays on normal Wi-Fi at full speed.
