Kind of off-topic, but since I see it (mis-)used here, I kind of dislike how the term 'router' has become synonymous with 'SOHO Wifi Access Point / Modem / Router thingy'...

In most 'professional' settings, all of these things are actually completely different devices with clear purposes, and this script would actually do nothing against a router. It might freak out some APs, but that's about it.
