Knowledge needed - What do you need to go Wifi with your computer?

[chilledmama]

Sorry for being dull...I have a PC which is obviously contacted to internet but also happens to be in DS's room. Thinking of buying a laptop for use while he is asleep (also only time I can get to computer for more than 20 seconds)but will need to use in other parts of home therfore thought WiFi but have no idea how to achieve it...Anybody know?

You need a router and the laptop needs to be wireless enabled (most new ones come like that, or buy something that plugs in the USB port)

Thats my knowledge used up as I have spent the last 3 days doing mine

a router and wifi enabled laptop. How do you get your internet? Phoneline or cable?
