  • Just like you can change your Windows PC to Linux, or install a custom ROM on Android, to have better control over your devices, it is also possible to change the firmware on most routers.

    OpenWRT is the most popular option for that. It’s a Linux based firmware, that has a package manager allowing you to install additional things on your router.

    For example, I have a TP-Link TL-WR902AC v3. Out of the box it is just a USB-powered 5GHz extender. After installing OpenWRT to it, I added:

    • WireGuard: to route all the traffic over my VPN
    • DNS-over-HTTPS: to encrypt all DNS requests
    • USBIP: this is because I sometimes use it to connect a webcam for my cat, and I forward the camera to my server in another room

    By adding WG and DoH to the “repeater”, I can connect this little guy to any public WiFi, and securely connect my devices to it.
