    I just got my router and Im pretty new at routing and want to learn. Looking at the DHCP clients table I see 2 entries -- my computer, and then another entry with no name, just an IP and MAC address and an expiry date.

    What is the second entry? Is it the router? If somebody was using my wireless network without permission would I see their computer listed here?

    If the MAC address does not match your computers, someoneelse may be connecting to your router. What is the DHCP lease time for your DHCP clients? A lease of 0 means the you have a lease of one day. Have you secured the router by using some sort of encryption? Any wired NICs connected to the router will also appear.

    Now there are three entries ( i added a laptop)

    #1 is my desktop, wired, w/ IPaddress, MAC address and a leasetime of 22"53:51

    #2 is the notebook,wireless, w/ IP, MAC, and leasetime of 21:14:55

    #3 is the UNKNOWN entry, no name, IP, MAC and a leasetime of 21:23:55

    Router is set to 128 bit WEP, MAC filtering (permit only), ssid hidden, default passwords, of course, have been changed (also the wireless channel). Does that help to ID the unknown entry, I hope...

    BTW How do you add a Username to the router login (default is no name)

    Thank You.

    thats odd, whats the mac address of the other device?
    and you can't add a username to the web interface login..

    Do you have any wired devices connected to the router, like a printserver, switch or media device? WEP only works for wireless device. The MAC Address filtering should have eliminated any other devices. On the Linksys products there is no way to add a User Name directly through the Web interface.

    AH HA!...<insight>

    Thanks for the help, gentlemen

    to wit:

    The MAC Address of ther other device is 00:0B:AD:26:3C:F8

    And I remember now that my TIVO is connected to the router to do its updates I BET THAT'S IT!!

    <feeling of satisfaction>

    Also-- what's the best way to log out of the router after checking the interface?

    Many Thanks again,

    Also there is a 5 port hub attached, but I don't think that that gets an IP address.

    And I cant ping the Tivo, but perhaps that is normal ( it works)..

    the hub won't get an ip, there should be one mac address for every intelegent device connected to your wrt via wireless or wired.
