Crazy Arduino Yun solution to a router problem

January 8, 2014

My father-in-law helps out with computer-related stuff at a coffee shop. They’ve been having WiFi troubles; the WiFi signal is strong, but they lose the internet connection. The solution has been to turn the router off and then back on; if they do that, things then work fine. He even installed a wall switch for this purpose, to make it easier.

He asked me whether I could build a device that would do this automatically. It sounded like an interesting project, and there’d be some useful things to learn in the process. Probably they should just buy a new router, but what follows here is a description of my crazy auto-router-resetter: my goal was to build an Arduino-based device that would check for an internet connection, and if the internet was down, use a PowerSwitch Tail (from Sparkfun) to shut off the router, wait 30 seconds, and turn it back on again.

Here’s a picture of the final product:
