I never heard of home routers which can't do that.
The laptop
is set to receive IP-Address and DNS-Server-Address automatically.
The router is set to always assign the same addresses to the laptop and to the PC because, in the past when it assigned addresses randomly, I had connection problems whenever the PC and laptop weren't started in the same order.
