    My son lost his laptop, which is configured to automatically log on to
    my wireless network (Win XP Home SP2 -- 802.11g). My network password
    is now compromised. I want to change it, but I don't know how to do
    so. Any help would be greatly appreciated.

    You change the wireless security password (and probably should change
    the SSID and router management password) from the router's
    configuration utility. Most routers are configured by entering the
    router address into a browser addressbar from a computer wired to the
    router. Then you will simply enter the new encryption key into any
    computers that connect wirelessly.

    An example is http://192.168.1.1 for a Linksys. Refer to your router's
    manual for details.

  3. Also, depending on the router, you might be able to configure it so ONLY
    those machines with designated "MAC addresses" can log onto the router. My
    Linksys WRT54GS router has this feature.

    I also installed software provided by AOL, called "Port Magic" that maps out
    the network, tell who's logged on", and also logs the "MAC addresses" anyone
    else, including intruders trying to log on.

  4. Also, depending on the router, such as my WRT54GS Linksys router, you can
    configure it such that only machines with certain "MAC addresses: can logon
    to the router, to the exclusion of all other.

    I also got "Port Magic" installed that logs all attempts to logon to the
    network, noting the "MAC addresses" on all intruders.

    Filtering by MAC address doesn't really provide good security. Yes, it
    may keep out your neighbor's kid, but MAC addresses are easily spoofed.
    Port Magic, like all the other AOL-provided "security" stuff is
    garbage. Better to have a good firewall and do proper security in the
    first place.

  6. Thanks for the comments. While we're at it, need some feedback from you.

    In addition to what I mentioned, I do have Norton's full suite, i.e.
    Internet Security, Anti Virus, Spam control, Parental control, Norton Ghost
    9.0 installed. I have a 4 PC XP network at my small business (all wired for
    security), and currently a 4 PC network at home for the family (may also wire
    up).

    I started using the AOL safety and security suite since I expanded to so
    many PC's so rapidly , and found buying and owning 8 or more copied of
    Nortons's to be a bit cost prohibitive. And I've been less than enthused wtih
    the problems caused by Norton's bloatware.

    In your professinal judgment then, what is the most cost effective way of
    purchasing and owning best software going forward, i.e. for Internet
    secuirty, firewall, spam, parental control etc.. I have no problem paying
    something for the software, but paying for 8 sets of Norton's given it's
    cost/benefit is not worth it.
