It may look like "a dog's breakfast," but this Wi-Fi detector ring is out of sight. When it detects a 2.4GHz signal, it flashes—even if it's not a proper Wi-Fi signal. With a little bit of help from a manufacturing company, though, I'm sure they could figure out how to filter the signal from the noise. I don't wear rings anymore, but this would give me a reason to.
