Downloaded and installed:

OpenSuse 11.2 - LiveCD  result: Gnome Network-Manager tells me there
is connection but no ping resposes, Firefox complains about conections
errors.

Mandriva 2010.0 (kernel 2.6.31-12) result: concection comes and goes
... generally the first boot of the day connects, but it lasts less
than 5min. The error code is the "deauthentication by local reason
(reason=3) again.

MS-Win7 : connects and is as fast as ever.

-- Any other suggestions?

Rogerio

PS: Will give OpenSuse a HD install atempt and will try to debug the
Mandriva for some time, future tries involve Debian Stable (old
kernel) and some Fedora (any suggestions?) and the NDISwrapper drive
in a Debian Testing (the Distro I need working)
