Should I put a VPN on my router?

A router VPN protects every device on your network, including smart TVs and consoles that cannot run VPN apps, and it counts as a single device with your provider. The trade offs are real: cheap routers slow down under encryption, and switching servers or turning the VPN off becomes less convenient.

What you gain

Installing the VPN at the router covers the whole household in one move. Devices that cannot run apps, such as smart TVs, consoles and smart home kit, get the same protection as your laptop, and guests are covered without installing anything. Everything behind the router appears to the internet as the VPN server.

It is also efficient against device limits, since the router counts as one connection however many devices sit behind it. With ROOT allowing up to ten devices, a router slot still leaves plenty of room for phones and laptops that travel.

What you give up

The router's processor does all the encryption, and consumer routers are rarely built for it. A budget model can cut a fast connection to a fraction of its speed, though WireGuard support in firmware such as OpenWrt has improved matters considerably. Check what your hardware can realistically push before committing.

Flexibility also drops. Changing server or switching the VPN off means visiting the router's admin page rather than tapping an app, and everything behind the router shares one exit location. Many households land on a hybrid: VPN on the router for the static devices, apps on the portable ones.

Related questions

Does my router support a VPN client?
Many stock firmwares only support being a VPN server, not a client. Look for explicit WireGuard or OpenVPN client support in the specifications, or for compatibility with firmware such as OpenWrt that adds it.
Will a router VPN slow down my whole network?
It can, because every device's traffic is encrypted by the router's modest processor. A capable router running WireGuard handles typical home speeds; entry level hardware often does not.
