Welp, seems I'm having a similar problem to what is descibed here.
I'll give similar information. I'm quite sure I was able to make my
card do hostap in the 5.3 days.

So then, I have a palmos client trying to connect as a client (using
autoscans to see if it is detected, though I have tried to set it up
manually as well) to my freebsd machine which is configured as
<root at uninfectable> [~] #ifconfig ath0 ssid Z mode 11b mediaopt hostap
channel 6 up
<root at uninfectable> [~] #ifconfig ath0
ath0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet 192.168.1.1 netmask 0xffffff00 broadcast 192.168.1.255
media: IEEE 802.11 Wireless Ethernet DS/11Mbps mode 11b <hostap>
ssid Z channel 6 bssid 00:05:4e:42:8b:2d
authmode OPEN privacy ON deftxkey UNDEF txpowmax 34 dtimperiod 1
I've tried this with and without an IP with the same results.
Everything in there looks right to me. I'm using compiled-into-kernel
ath_hal, ath, and ath_rate_sample.

For mine it is an 11b setup.

In case this is useful:
<root at uninfectable> [~] #athstats
48 tx management frames
28 tx frames discarded prior to association
8 tx failed 'cuz too many retries
96 long on-chip tx retries
17 tx frames with no ack marked
112 rx failed 'cuz of bad CRC
42334 beacons transmitted
139 periodic calibrations
rssi of last ack: 4
 tx 39 rx 0
 tx 0 rx 405
That's all the information I can think of. I'm quite sure this used
to work with an ifconfig incantation (almost) exactly like that. In
fact, I often copied and pasted the one from the man page and it
worked. It seems that it doesn't now. Is there some change that
occurred that I should be aware of and missed?
Thanks in advance for your time and expertise,
