my soekris 4801 with either a wistrom CM9 or senao 400mW miniPCI card &
ath chipset are not putting out as much grunt under OpenBSD as under
FreeBSD/pfSense, at least according to my end users in the downstairs
flat :-)
2 questions:
is there anything simple that could quantify the power, e.g. using some
feature of ports@ or openbsd?
is there anything further i could do to boost up the range? other than
the 2nd aerial which has definitely helped... at least anecdotally?
$ ifconfig ath0

up
lastly i got a panic (something new to me) while ifconfig up'ing ath0
with various parameters. i think this should be repeatable, so i'll read
through http://www.openbsd.org/report.html when i have time & come back
with something more concrete; at least here it's not going to get
lost/forgotten.
