This is current/i386 on an IBM Thinkpad T40.
It comes with an ipw(4) wifi interface, which works fine. Anyway,
the ipw(4) seems to be one of the substantial battery eaters. So
I would like to not use the interface when running on battery
and not actually using a wifi connection.
Running 'ifconfig ipw0 down' seems to do that: the antenna icon led
switches off, and time left (as reported by apm) starts increasing.
(What would be a more rigorous way to see that the battery is actually
running off more slowly now, others being equal? The machine doesn't
have any sensors, as reported by 'sysctl hw').
I would like to let that happen automatically, if only because sometimes
I forget to do that, and drain the battery considerably faster.
What is the preffered way to do that? Is ifstated(8) the way?
istated(8) is monitoring the 'interface link state'.
Is 'no network' recognizable as an interface link state?
What I would like to recognize with ipw0 is what
'no carrier' would be for an ethernet interface:
is that a good analogy? 'no network' just means
the interface is not associated to any network,
not that there isn't a nework around, right?
Now I tend to put
ifconfig ipw0 | grep 'no network' > /dev/null && ifconfig ipw0 down
into the root's crontab but that seems a bit crude.
