wifirepeater

Greetings people! Im not quite sure if thats the right place to ask but here we go. I have 2 Xiaomi android devices,1 desktop, and access to a network. My endgoal would be to have Internet Access in my PC and after some searching i ended up downloading an app that lets you share the network...

I have Dlink DIR 816, the product descirption on both website and manual says it has Wifi Repeater but when i access the router main page i cant find the option to turn it on in any tabs. And the videos on Youtube are either old or using old firmware
