My understanding of Vista ad-hoc networking:-
1. You need an SSID or it won't create or join a network.
2. Unless you save the ad-hoc network details then when you stop using
the ad-hoc capability or move out of range of the network you have been
connected to then the ad-hoc details are removed.

I doubt that your wireless card can receive and transmit at the same
time so I would be curious how your card could receive a transmission
from itself.

It's not something I can repeat with Inssider ver 1.1.1.0318.
I also tried putting my adapter in ad-hoc mode and running Inssider and
apart from seeing fewer AP's I did not pick an ad-hoc network.

Were you running the Proset s'ware to control the Intel card or just
using Vista?
