Can I do this? - wifi lan thing

Ok so I built a new pc today and it has wifi intergrated on the mobo, never set up a wifi network before but on my laptop I used my laptop to enter other wifi networks for internet etc
Usually my laptop is connected through rj45 to our home lan

So anyway
We have a server PC for the net
My new pc connects to that server for the net
BUT I want to be able to connect my laptop through my new PC’s wifi then to the server PC so I can get the net without a cable

When I tried setting it up it just had a conflict with the IP because it would have been the same as the server 192.168.0.1

Is it even posible?
Thanks
