heres a drawing how it should look like. ISP modem has wifi built in but i want to add a new router to a second part of the house to connect to a second pc but to also have another wifi because the first signal isnt strong enough.
So is it possible to have 2 wifis? One emitting from the isp modem other one from the router?

Yes it's possible.

It tends to be better to run the second route as a AP because then you have 1 network in the house rather than 2
