XP laptop turned into a wireless bridge - Can't make it work

On a thinkpad laptop with two adapters:

- a wireless connected to the public internet trough
a Access Point (AP) router and cable modem
- a builtin ethernet NIC to which an IP phone is connected
with a crossover cable.

I wish to bridge the two adapters so that the IP phone is issued
an internal LAN IP (192.168.xxx.xx) by the DHCP server on
the router and ends up "on-line" connected to the internet.

Using "netsh" command I checked that the wireless adapter
(Orinoco PCMCIA) is indeed in promiscuous mode and even usued
the "forcecompatmode=enable" command just in case.

The soft XP bridge failed to aquire an IP from the router 'cause
as soon as XP built the bridge, the wireless adapter link
to the router (nd its DHCP server) is lost. What is wrong?
I read an MS article that it is supposed to work:

http://www.microsoft.com/windowsxp/e.../02april22.asp

Could it be that the Orinoco wireless adapter does not
support promiscuous mode even though it reports that it does and
is enabled? Where could I find if it does or does not?
