Alexa will turn off wi-fi when it's homework time

NEW YORK--I've been a big fan of the $499 eero Wi-Fi system since February when it solved the poky networking issues and dead zones in my house that had previously made my Internet hiccup and stutter all too often. For folks with an Echo, Echo Dot or Amazon Tap, Alexa brings three skill sets to eero. You can ask Alexa to turn off the LED lights on an eero router, when, say, you want to watch a movie in pitch black or go to sleep. If you've misplaced your smartphone or some other device that's connected to Wi-Fi in your house, Alexa can help you locate it, by letting you know which eero it is closest to. And here's a feature parents may come to love.
