Without discussing the cleanliness of the wireless subsystem, I don't
feel bad proposing alternatives :)

I'm fine adapting to your preferred solution either way, so could you
clarify what should I do:
- Drop that commit entirely.
- Move things into their own submenu (we can discuss the naming,
  "Low range wireless Networks" might be a good start).
- Keep it like it is.
