[QUOTE="cwa107, post: 1149614, member: 24098"] Not necessarily. The symptoms point to two different things - either the router isn't handing out DHCP (in my experience, this is rare) or the client and the router are not able to properly negotiate and establish a secure session (very common). When you connect to a WEP-secured wireless network, you have to enter a case-sensitive 26-character WEP key (and it can't be the same as the MAC address as that's only 12-characters, WEP requires a fixed passphrase). Depending on the client OS, it may need to have a $ placed at the beginning of the entry. If they've got it setup to use MAC filtering and your Mac's MAC address isn't in the table, when you go to connect (even if it's using the right WEP key), it will manifest itself as looking like it's connected, but actually using a self-assigned IP. All of this can be alleviated by switching to the more modern WPA (or better, WPA2) encryption which works with a simple password (and turn off MAC-filtering as it is generally useless as a means of securing a network).
