Hello,
I am testing soekris 4801 based access point with an atheros miniPCI card
(802.11abg miniPCI NL-5354MP). I
successfully established a connection between two soekris 4801 one configured
in hostap mode the other in bss mode
(802.11b mode). The problem comes when I try to configure those miniPCI in
802.11a/g or when I try to change modes.
Sometimes when I'm changing the mode of operation from 802.11b to 802.11a I get
some ath0 device timeout errors or a
panic and an reboot.

Until here everything is working as supposed. Let's change that to 802.11a.

In manual of ath(4) this error should not happen. If I repeat that, the errors
are gone, but I have no connection
between two boxes.

I'll try to change the mode of operation to 802.11g:
BOX1# ifconfig ath0 inet 172.31.0.5 netmask 255.255.255.252 media autoselect
mediaopt hostap nwid testlink1 mode 11g chan 1
ifconfig: SIOCS80211CHANNEL: Invalid argument
That happens for everything I try to select for the channel number. If I omit
the channel number, the card changes its
mode to 802.11g but the channel number stays from previous configuration:
BOX1# ifconfig ath0
ath0: flags=8863<UP,BROADCAST,NOTRAILERS,RUNNING,SIMPLEX,MULTICAST> mtu 1500
lladdr 00:02:6f:39:61:8b

inet 172.31.0.5 netmask 0xfffffffc broadcast 172.31.0.7
It is still not possible to select another channel number so I will unset that
channel.
BOX1# ifconfig ath0 inet 172.31.0.5 netmask 255.255.255.252 media autoselect
mediaopt hostap nwid testlink1 mode 11g
-chan 52
Now the box panics and reboots.

If I repeate the process of changing modes and channel I can get the same
result on BOX2.
