I am doing an application on PPC to scan APs nearby. How can I get the Beacon
Frames from APs?
Thanks!

As far as I know, you can't. Why? If you just want a list of access points
that the radio can hear, that's pretty easy. Look at OpenNETCF's .Net
namespace.

Hi, Paul T.
Thank you for your help.
In fact, I only want to get a field named "Private IE" in Beacon Frame. I
know about the "OpenNETCF.net namespace" you mentioned. But I can't obtain
the "Private IE" through the classes in OpenNETCF.net.
Do I have to use the WLan Adapter's SDK?
Could you give me some advices?
Thanks!

You still haven't answered my question... You're telling us *how* you want
to do something, but not *why*.

Hi, Paul T.
I am sorry not to explain explicitly my question. Now, let me do it.
Our company is developing a kind of AP. We want to put some special
information in the beacon. So I need to capture the original beacon-frame to
obtain these information. I also need to know the signalstrength of the APs
around my PPC.
I have not got the solutions to these problems.
Could you help me?
Thanks a lot!

Sincerely
Wisent

You may be able to do that with a miniport filter driver running on top of
the network adapter driver, but you're not going to do it from managed code
at the application layer. The Platform Builder help has information on
filter drivers.

Isn't it generally a bad idea to do that sort of thing? Aren't you going to
have compatibility problems?
