The bug is a clash in interface naming.

When the system brings the fixed wireless interface up, it gets assigned name "netcs0". That conflicts with "netcs0" which should be assigned to PCMCIA socket #0.

After some thought it seems that the only proper fix (actually a hack) is to add the following after line 17 in /etc/network/wireless-start:

SOCKET=`expr $SOCKET + 1`

This will shift naming of all PCMCIA interfaces by +1 and therefore there will be no clash with netcs0.

I cannot think of a proper automatic fix right now... I don't want to scrap the interface name<->socket number binding scheme altogether as it may lead to unpredictable mapping between interface names and physical cards, as there is no guarantee that all interfaces will be discovered in the same order each time.

Anyway Vladimir suggested a bug is out there that could cause the problem and
I prefer to fix the bug (in case it exists). He also suggested a race
condition could exists but I could not find anything in that direction.

Able, a kludge to work around the Wisp-Disp essid problem with three radios
is

to set the


essid of netcs2 in rc.local, ie:

/sbin/iwconfig netcs2 essid my_essid

I have not done a lot of testing, but it worked okay in a few tests. The

"test" essid may


show up on a wireless users system just after Wisp-Dist boots, but it goes

away in about


30 seconds.
