I suppose the case when "wifi detect" is invoked but no phy exists on
the system (e.g. because the radio hardware is not installed - think USB).
In this case the entire /sys/class/ieee80211 is likely missing which
will cause "ls" to print a "No such file or directory" error.
Actually I do not really like that whole "for x in $(ls ...)" construct,
something like the following would save one fork and also not produce
errors:
for dev in /sys/class/ieee80211/*; do
if [ -h "$dev" ]; then
# do something with ${dev##*/}
fi
done
