Comment:
it's system software (even if interface down, wireless extensions still
report it as having signal - no essid, not associated with anything, no
wireless key, but it keeps a signal value that is also entirely bogus -
should be less than 94, not greater than). illume simply uses the wireless
extensions netlink loopback and asks the kernel what the signal of the
first wifi device it finds is. same thing iwconfig does:
