Zyair B-2000

I have replaced a Linksys BEFW11P1 Access Point with the new Zyxel Zyair
B-2000. I have not been able to successfully complete the installation. I am
on Windows XP-Home, my ISP is Earthlink over a Warner Cable broadband
connection. It am guessing that the ISP will not recognize the added
hardware.

I can provide additional information, but does anyone have a clue about
this? The old Linksys model installed without any special consideration of
Earthlink or Warner Cable.
