My thanks to Eero for sponsoring this week’s DF RSS feed. Through December 25, save $50 on eero Home Wi-Fi Systems and give the gift of never having to deal with bad Wi-Fi again. Eero is easy to set up, and blankets your entire home with fast, super-stable Wi-Fi. I replaced my Airport Base Station with Eero over a year ago and couldn’t be happier. Visit eero.com to learn more.
