I have heard that Linksys is a good make for networking components. I found this:

I want to connect to my dial-up internet connection from my PC, and share the internet from my PC to my laptop which is connected to the wireless router. Also, I want to play multi player games between my PC and laptop. Will this router enable me to do that?

Thanks.
