    Default Connecting to AP with disabled DHCP

    Hi all, I have a SMCWBR14-G wireless router in my home and have it connected to the internet for 24/7. I want only my family to have access to the internet by connecting to the wireless router via wi-fi.

    There are 3 laptops here sometimes there are many guest or other family members come here want access to the internet if they are visiting my house. I try to use the WEP. But sometime when I see the log, I see other people are connected to my router. Even though I gradually change the WEP, sometime there are still illegal clients connected to my router.
    Then I learn to use BackTrack 2 Final and I've discovered it's quite easy to crack my WEP (after I watch the video posted by Xploitz, many thanks to you). So I try to disable the DHCP and use static IP for the LAN. But again, I discovered that there are illegal clients connected to my router via wi-fi.

    My questions are:
    -How can they know my router LAN IP address, /subnet, and have them connected to the internet through my router even I have disabled my DHCP on my router?
    -Does anyone know the process and the tools they are using for scanning and connecting to my router?
    -Is it possible to know my router LAN IP address, WAN IP address, and DNS IP address without logging in to my router?
    -Is it possible my router's password cracked?
    I have changed the default password for my router, I'm just curious to know because it doesn't ask to input username to login, password only.

    Thank you very much

    Why not change it to WPA, and use a random password?
