The best way is to get a wireless router. You can get them from about $35 - $200. You'll hook your PC up to the router with an ethernet cable, which should come with the router you purchase. And you should be able to hook up your laptop wirelessly. Most laptops nowadays come with what they call a wireless adaptor installed by the factory. This adaptor allows you to hook up to the internet through your wireless router. If your laptop is old, you might have to buy a wireless adaptor, but I doubt you'll have to do that.

By the way, make sure your laptop and the router have the same wireless standard. There's 802.11b, 802.11g, and 802.11n. The router will say it right on the box. And it's probably written somewhere on the bottom of your laptop.

Hope this helps.

You need a router. Wired is perfectly safe (unless of course there is someone in your house). Wireless encryption can easily be cracked by people that know what they are doing.
Not necessarily!!

Internet Connection sharing is possible, and quite secure (you would need some firewall software).
