WiFi-acitivity

Something that my laptop doesn't have is a WiFi-activity indicator. It has LEDs for Ethernet, yet not for WiFi.

That problem is rather simple to solve!

To get around the missing WiFi-activity indicator problem, all you need is an ESP8266 like the WeMos D1 and some software.

The software is really simple: it enables "promiscuous mode" for WiFi and then blinks the built-in LED when a packet is received. Add some frequency-hopping and you're done.
