Going wireless

My home operates on a system of computers hooked up via cat5 and wireless connections. It's very easy to do using a wireless router -- what I do recommend is you buy a router that will do both, offer wireless and hardlined connections. This way you have the option. My tower as an example has the ability to be wireless but it's much easier to connect it through ethernet. No matter what, make sure you secure your wireless connection, while the neighbors might appreciate the ability to connect, others may have a bit more nefarious ideas in mind.
