Pick a different IP for your PC then or you messed up something with the gateway or DNS.
Seems like you are picking an IP at the low end of the range for your PC and that gets assigned to your laptop. Set your PC to like 192.168.1.199 or something, so if your router starts handing out IP's and starts at 100, unless you have 99 devices, 199 will never be used. The router doesn't know that you assigned the IP to that PC, so it will try and hand it out. Put it at the end of the range and it won't.
You can also tell your router to assign the IP based on MAC address of your PC and let the router handle giving a static IP instead of setting it on the PC.
