What makes a Don’t Buy wi-fi router or extender?

While our Best Buy wi-fi routers and extenders provide first-class wi-fi speed and coverage throughout your home, no matter the size, we also find some products come up short in our extensive tests. From ISP-supplied routers that suffer from poor security and data privacy settings, to other models that are confusing and difficult to set up.
