    I just installed a linksys wireless and in the process, found sevreral neighbors also had these systems. I just was curious and was able to log into all the systems. I will use the wep encryption and new pw and ID but am I still safe from an attack? I am wondering if I should just make a wired solution only.
    Thanks,
    Rich

    Anything can be compromised... So.. What can you do? Well WEP is a start. Also change your log in to the admin pages of your router. Then if you can use WPA.. I suggest TKIP with AES. Then use a big passphrase like

    The longer the better, as it will take longer to crack.
    also change it often.
    Turn on Mac Filtering allowing only computers with identified MACs to connect. Note that with certain programs you can pick up someone's mac pretty easily.

    Also, don't bother turning the SSID off. Someone will see it also.

    These are a couple of suggestions.. Some others might have more.

    Hope that helps and glad to see that you understand how open these devices are when you plug them in.

    Don't you mean WPA(PSK) with AES?

    You can also turn the wireless portion off when you are not using it and try placing the device towards the center of the house and not a window which would increase the wireless range outside the house.

    Also if you see someone parked outside your house with huge antennas for long periods of time then you can start worrying :)

    WPA-PSK TKIP is the most secure. If there are other unsecured networks in your neighbor, they will get hit long before yours. The key changes periodically, you should use a long key.
