Hi,
there are two atheros cards on one board. When i apply the following
settings:
{{{
wlanconfig ath0 create wlandev wifi0 wlanmode master
wlanconfig ath1 create wlandev wifi0 wlanmode master
iwconfig ath0 essid netlab2
iwconfig ath0 channel 1
iwconfig ath0 key 35000a29631d2130ef66639da49472e1
iwconfig ath1 essid netlab
iwconfig ath1 channel 10
iwconfig ath1 key 35000a29631d2130ef66639da49472e1
brctl addbr br0
ifconfig eth0 0.0.0.0
ifconfig ath0 0.0.0.0
ifconfig ath1 0.0.0.0
brctl addif br0 ath1
brctl addif br0 eth0
}}}
The cards seem to be cloned. The output after applying the cmds for
iwconfig is the following:
{{{
ath0 IEEE 802.11g ESSID:"netlab2"

I played arround and i got a oops after i destroyed the two devices and
applyed the script again.
Look at iwconfig... like you see its the same channel frequ... but ath0
should use channel 10 and ath1 channel 1... so lets see what happens when
a client connects to ath1:
{{{
ath0 IEEE 802.11g ESSID:"netlab2"

Ooops... client1 is only connected to ath1 but ath0 also display the link
quality? wtf? I have tryed to use a other wepkey on ath0 then on ath1 but
its the same... the client connects to ath1 and ath0 also displays the
same link quality and such things... The client also got some problem with
this... it will get a lot of rx invalid pkgs(Rx invalid nwid:15387 after
some minutes). When i kill ath0 so that only ath1 is working... the rx
invalid pkgs are stopping and it works.
So my next idea was the the bridge is doing some magic foo but its the
same problem without the brctl stuff.
Does anybody have a idea?
