A script to find and connect to known wifi networks on OpenBSD. Works for me on my iwn card in my laptop
#!/bin/sh
# find_network.sh - An OpenBSD Wireless Network configurator
# Looks for available networks listed at the end of the script
# Use this by adding "!/path/to/find_network.sh \$if" to your wlan hostname.if
if=$1
if [ -z "$if" ]; then
echo "Usage: $0 interface" >&2
exit 2;
