I wanted to make some iperf tests so I connected keyboard and monitor.
I could not connect anymore after this. My reaction? What a Terrible

After experimenting, it appeared to be about direction of the antenna.
Moving it by 90 degrees caused disconnection and reconnecting was not
possible. Moving it back worked like a charm... well - kind of -
because speed was still horrible. However at least connecting was
working fine.
So we may be lacking something important about calibration. But on the
other hand, wl or ndiswrapper are not much better. Speed achieved with
ndiswrapper can be 3Mb/s and 15Mb/s after 10 minutes (without touching

To make it even more ugly, PIO mode is almost not working for me. I
can connect to the network (with antenna in the correct direction),
but getting IP (dhcp) causes loosing authentication. Every time. After
loosing connection taking interface down & up is required.

I'm leaving this for now. Hope noone will ever meet card like mine.
