Hello
Maybe there is problem with ath
I have point-to-point uplink with ath 5213 based cards
with

  6.0-CURRENT #2: Thu Jun 30 02:39:34 CEST 2005
  hw.ath.hal.version: 0.9.14.9
  ifconfig_ath0="10.27.64.78/30 ssid HA2BH media OFDM/24Mbps mode 11a up"
   bhillz-F# ifconfig ath0 list ap
   SSID            BSSID              CHAN RATE  S:N   INT CAPS
   HA2BH           00:90:4b:ca:33:52  149   54M 32:0   100 E

and on the other side:
   5.4-STABLE #6: Sat May 28 11:01:07 CEST 2005
   hw.ath.hal.version: 0.9.6.3
   ifconfig_ath0="10.27.64.77/30 ssid HA2BH channel 149 media autoselect
mode 11a mediaopt hostap up"
   habr# wicontrol ath0 -l | grep signal
        Quality/Signal/Noise [signal]:  [ 0 / 34 / 0 ]


The problem is, that "client" side seems to be sendig corrupted data
(tcpdump above), I tried to switch client<->hostap cards (in config) but
the same thing again.
I also tried CURRENT <-> CURRENT  machines, it do the same thing
I have more interfaces (fxp, wi, vlan) on these boxes and OSPF runs
there without any problem, so I think it could be ath specific problem ?

Does anybody have any idea where could be the problem ?
If will anybody be interested in, I can provide more info.
Thanks
Jiri
