The 12 must-have tech gifts of 2016

Give the gift of always-working Wi-Fi.

Most homes have one router, but Eero says that's like asking a speaker in the living room to make sure audio gets to your upstairs bathroom.

Eero's Wi-Fi extension routers make sure each inch of your house is covered, so you can stream movies and download big files without walking around to find the right spot.

The neat part is you can shut off Wi-Fi accessibility in certain parts of the home, such as a children's room at bedtime.

One Eero costs $199, a two pack costs $349 and a three pack is $499 -- although you can find them discounted on sites like Amazon.
