I recommend replacing 'wi0' with ${interface} - it makes the script more
portable. The pointlessness level would seem to go up a tad given that
the script is called 'start_if.wi0', but if that ever changed, it would
reduce from 10 to 1 the number of places you'd have to change it.
You could even go so far as to replace 'wicontrol' with
'${interface}control'. When I last looked, ancontrol took many of the
same arguments. You could hardlink start_if.wi0 to start_if.an0 and it
may still work.
The -c argument to wicontrol does not work and will likely never work.
Because of that, -q is also pointless. The short answer is it's simply
not as simple as that to set up an access point, and Lucent hasn't
publicly documented how to go about it. -p 1 is no longer necessary, as
BSS mode is now the default as of 4.3. You would have to explicitely
choose peer-to-peer mode if you wanted it with '-p 3'. -f is also
unnecessary in BSS mode.
Note that you can't make your own ad-hoc bridge with a wi card either,
since wi cards cannot do promiscuous transmissions. That is, the card
will not transmit frames with an Ethernet address other than its own.
This functionality is required for bridging. You can make a router,
though, but BSS mode has some important advantages over adhoc:
Power management is not possible in adhoc
Promiscuous reception is not assured and performance may decline due to
the 'hidden station' problem (B can see A and C, but A and C can't see
each other).
