Ok this doesn't look too bad. Looks like your signal quality is not
good, the ber is quite high. Besides the antenna, the cause can also be
a bad cable. This also explains why scanning is not stable:
Especially with auto configuration, it might take more than a second for
the channel decoder to lock. As fas as i remember, w_scan has an option
to increase the timeout.
Amy i ask you to run femon or tzap for several minutes to see whether
the reception is stable?
You might also check the other functions of the card and report. I don't
have it so i can't verify the confguration.

Best regards
