Reusing my old router as a switch

I needed a 2nd Gigabit Switch. The prices bugged me, so I got an idea.
My old TP-Link router has gigabit ports, so I reconfigured it for working as a switch. Turned off WiFi and any router service. Works nicely.

For the money left, I bought a TP-Link power plug which can be controlled with Google home over WiFi. Yay. "Okay Google, make it warm" 😊
