I've been testing {de,re}auth and {de,re}assoc with Win32 and OpenBSD
clients (sta's) against a bridging 3.1-beta host-ap. Every client
(sta) I've tried so far works as expected. Some early observations:
WEP doesn't seem to work in host-ap mode, but I understand this is normal.
wihap_timer causes idle OpenBSD 2.9 & 3.1 stations to disassoc/reassoc
every 30 secs. Win2K (Orinoco) clients don't do this if powersave mode
is enabled. In both cases, established TCP sessions are unaffected.
TCP connections (ssh) survive host-ap reboot or client sta going out
then back into range (expected, but very nice).
A new 3.1 install worked seamlessly via wi0 (using a new floppyC31.fs).
Todd's changes to if_wireg.h on 30/3 have made my Netgear MA301 (PLX
based) PCI adapter work. (I used to get wi0: device timeout).
Host-ap client stations appear to get multiple duplicate replies when
pinging other sta's or wired hosts on the other side of the bridge.
When operating in host-ap mode 'wicontrol -s <name>' sets the AP name.
I've appended my settings/results below. This was with code cvs'd and
built 2pm Sat 30th UTC using tag OPENBSD_3_1 (dmesg appended).
