Hi,
When I was documenting the steps of configuring a Windows7 wireless client for
eduroam recently, I encountered the following problems:

* I could find no way to make the client support both WPA2 and WPA1 within a
profile. So, if you configure a profile for WPA2, then it will not connect to
the same SSID via WPA1 if you roam to a site where only WPA1 is offered. I
guess that you could argue that this is a reasonable restriction to apply, in
some circumstances, but I think the option of supporting both should be
available to the end user.

* Also, because the profiles are named according to the SSID, you can't create
more than one profile for the same SSID (so, for example, you can't add a WPA1
eduroam profile as less preferred than a WPA2 eduroam profile).

I could not find a workaround to either of the above issues and from a quick
check I think the same issues apply to the Windows Vista client. Both are
significant problems, I believe.

Regards,
Louis.
