    My LAN consists of 3 PCs connected to my D-Link Wireless router via Category
    5 cable. On rare occasions I also use a laptop that gains access to the LAN
    with a wireless connection. The router connects to the outside world with a
    cable modem.

    I use Windows XP on all of my computers, have the XP firewall activated, and
    use an antivirus and antispyware program. Is it possible for someone outside
    my home to gain access to my system in any way when the laptop is not being
    used? If so, what can I do to prevent it? Thanks.

    Gain access to what? It is not known yet how to find way through Windows
    firewall, and what Alice will find there.

    If the questioon is about the network infrastructure, the answer would be -
    if you use encryption and authentication, the intrusion will unlikely to
    happen. If you are not that concerned about access to the network,
    encryption is goodness, as likes of POP3 mail passwords are often sent in
    clear - discloses you information and then some.

    By "gain access", I meant anything that my system uses - such as access to
    the internet (not too concerned about that), access to my important files
    (very concerned), access to my email, or access to these things in a
    destructive way (very, very concerned).

    If you follow good security practices, then it is unlikely. I won't say
    "impossible", but it is unlikely. You want to use wireless encryption,
    strong passwords, and keep your computer clean. Here are some links to
    help you with good security practices:

    Hi Papa

    One option is disable Wireless in the router and enable it as and when
    needed as well as strong security when Wireless is enabled
