I can't guess your internet sharing method on the PC. W10 has a native method which turns the PC into a router so we don't use the router as a router but a WAP.
So read this recent back and forth about sharing as it has links on the Windows setup then google the following "How to use my router as a WAP."
Read https://www.cnet.com/forums/discussions/local-area-network/ first.
i want my pc to be connected to the modem, so i have a direct connection from the pc (pppoe).
This works without any problems. Now I want to share the internet from my PC to the router.
My router is a Fritzbox 7360, where I set it to "already existing internet". I also connected the network cable to port 1.
On my PC I have shared the internet for the network card which is connected to the router. My router indicates that it is connected to the ip 192.168.168.137.1. But when I connect to the router with my smartphone, there is no internet.
i hope someone can help me here.
I know i could connect my modem with router but i dont want that.
