Is it possible to set up the data-rate to 22 Mbits?
The actual Windows driver works with 22 Mbits.

Is ist also possible to show the actual datarate in
"iwconfig"?
I don't think that it has always 11 Mbits. ?!?

Has anybody heard something of the "4x Mode"?
Is ist in the moment active or not?
What does it mean?

Thank's a lot for the development.

    Well, of course you can set the rate to 22Mbps.
    As described in a current README, there's some communication
    problem with 11Mbps APs when setting to 22Mbps (fallback
    broken for some stupid reason), so we default to 11.

    I'll have a look at the rate displaying.

    About 4x mode: RTFM. It's simply a non-standard way to keep
    sending all data at 22Mbps, thus reaching a much higher
    throughput. Since it's non-standard, implementation priority
    is low.

    Fallback is broken since if you do hardware fallback (fall
    back after e.g. 2 attempts at a higher rate), then you'd
    have horrible ping times until transfer success. Thus we'd
    need to implement a clever software fallback and step-up
    algorithm (since the firmware doesn't handle it for us),
    which will take time.

    AFAICS the actual data rate is not necessarily supposed to
    be displayed (a '=' indicates a FIXED rate, whereas a ':' in
    the display is an AUTO rate setting).
    But OTOH it would still be nice to change it to actually do
    display the current rate (but this would be done once
    fallback is implemented properly).

    Everything implemented except for the "don't hold your
    breath" 4x mode, so closing. Feel free to open a 4x mode
    Request if needed.
