To prevent someone else from accessing your records
There is a few concerns a person would have when accessing a household wireless device. Some of the concerns a person would have would be interference, security and weather.
Wireless LAN technology uses an open media (the radio frequency). Other than shielding your entire house in a closed metal cage, you cannot prevent anyone from accessing it. However, you should enable solid security using WPA based on a strong (=long and difficult to guess) password to prevent anyone but those knowing the password from using your wireless network. You can't stop them from trying (except when building a Faraday's cage around your house), but you can prevent them from succeeding.
The WEP key is the same one your PC or laptop uses to access your wireless router. If you don't have a wireless router, then you're looking at someone else's, the WEP key is actually there to stop unauthorised people like you from accessing it.

If someone has access to the data stream from your computer to any servers you connect to, then yes (in the example of wireless connections). Although it's unlikely they can control your computer, it can see what information you are sending or receiving. You can prevent someone accessing your computer by using a simple firewall, and to prevent someone accessing the data stream, you should use an encryption key. The instructions of how to do so should be on the software manufacturer's website. (microsoft = microsoft.com) Use SSL connections when available to ensure security. And never place personal information over a non-secure connection. The way to identify a secure connection is simple, most web browsers have a logo meaning security is enabled. It is usually a closed padlock. These icons will be found either on the address bar or on the status bar.
