WRT54GS Anomaly !

    The Serial No: of my WRT54GS is CGN20DC54989.

    I have the following LAN setup which has my IBM T60 laptop networked to a desktop which connects to the Web through a ZyXEL DSL modem and a WTR54GS router.

    When I first switched on the laptop it detected this wireless network by its SSID and which was described as an "unsecured wireless connection."

    I then attempted to secure this connection by inserting the router's Installation CD into the desktop thus initiating the router setup process. This stopped with the message :-

    "The router is unable to connect to the Internet"

    This is puzzling because the PC IS connected to the internet and so is the laptop through its wireless hookup !I can surf the net without a problem on both machines.

    It also prevented me from proceeding to set encryption as I could not get beyond this message.

    I also don't know how to restrict access to PC'S by their MAC addresses as recommended by many security articles - there doesn't seem to be a facility to do this with this router.

    I would , therefore , be glad of the answers to the following questions:-

    1.Can you tell me how do I secure this LAN in view of the problem indicated in question 2?

    2.Why does the Linksys CD say this router is not connected to the internet when it is ?

    In spite of having set the SSID transmission to "DISABLE" , my SSID ( renamed to "xxxxxx") is nevertheless being "seen" by the wirelessly connected laptop.

    3.Why is this happening? and , finally ,:-

    4. Is it possible to restrict access to this wireless LAN by the allocation of those MAC addresses which have been chosen?
