Here's how I do it in my /etc/whereami/detect.conf
======================================================
default undocked
testmii eth0 lan
if lan
set INTERFACE eth0
testdhcp '*.*.*.*' dhcp
testarp eth0,00:24:5e:17:12:11,10.2.0.4 neta
testping 172.16.100.2,172.16.100.86 netb
testping 192.168.78.1,192.168.78.55 netc
testping 202.49.41.18,202.49.41.1 netd
testping 10.2.0.2,10.2.0.253 netf
else
# Crude, but it works.
testmodule orinoco_cs netg
testmodule nokia_c110 netg
fi
if dhcp
testdhcp 192.168.2.* neth
testdhcp 192.168.5.* neti
testdhcp 192.168.7.* netj
testdhcp 192.168.55.* netk
testdhcp 10.1.0.* netl
testdhcp 10.2.0.* netf
testdhcp 10.3.0.* netm
testdhcp 192.168.1.7 netn
testdhcp 192.168.10.* neto
testdhcp 192.168.0.* netp
testdhcp 172.16.40.* netq
fi

The testping and testarp find fixed IP's, the testdhcp finds what you
got assigned. Most of my nets are DHCP, so I run that test first and
switch to arp/ping if they are not available.

Yeah, as you can see above I test the wireless LAN pretty crudely, but
so far I only have one. Taking it further for more WLAN connections
would be to do my tests and then do a block of (presumably) dhcp tests
on that interface as well.

Probably.
