Hello Everyone!

To put it simple: IT WORKS! :)

The recipe:

wireless-testing-git pull from earlier today with the only
modification being this:

Otherwise hostapd-0.6.7, nothing special on the userland.

In detail:

- Open System mode works with Tx fluctuating between 4-6 Mbps
and Rx between 10-14 Mbps regardless of the distance or signal
strength. It was tested standing 1m away from the AP antenna
(signal 100/100) up to 15m away with several thick walls in
between (signal 60/100) but throughput figures remained the
same.

- MAC address filtering does work. It probably always did,
I think I've just messed up the configuration the last time
and that was the reason back then, sorry.

- WEP mode does not work, apparently the driver does not allow
setting it and hostapd is exiting on that error.

- WPA and WPA2 have been tested and they seem to be working!

A small hint is that the WPA pre-shared key should be given
in hex both for hostapd and on the clients, otherwise there can
be differences in translation from ASCII to hex which in turn
may lead to an authentication failure.

I've tried to push some 100 MBs through the link in both directions
both with WPA/WPA2 turned off and then on and it seems to be rock
solid so far. CPU usage both on the AP host and the client is
negligible in any case, the throughput isn't affected by turning
on WPA/WPA2 either.

Thank you all!

Best regards,
Sab
