Hello All - I am hoping some techno wizz may be able to help me get my head around this wireless networking stuff.

O.K. this is what I would like to achieve. Currently I have a PC that is connected to the net via a ADSL2 modem with a cable (usb, or ethernet - can't remember) I will soon be getting an Netbook which has built in wirless capability, which I would like to be able to connect to the net wirelessly whilst at home, and also strems media to the netbook.
I would also like (but not essential) about 4 ethernet ports built in so if a do host a small LAN game at my place, people can connect without any more hubs.

So...what do I need?? Any help appreciated.
