If your home is large, irregularly shaped, or just built from materials that aren't conducive to the unfettered movement of radio waves, one Wi-Fi router might not be enough to get a consistent and fast signal in every corner of your house. But the cure for your dead zone woes is a simple one: a mesh Wi-Fi system.

Rather than relying on a single base station to blanket your entire house in Wi-Fi, mesh routers work in tandem with each other to boost signals further, and bounce them around impenetrable walls that might otherwise block your internet connection. Best of all, you'll still only have to plug one of them into your modem; the others only need a power outlet to work.

A company called Eero popularized the concept of home mesh networking several years ago, and was purchased by Amazon back in February. We were eager to see what kinds of Black Friday deals Amazon would be able to offer on its new toy, and they didn't disappoint: for a limited time, you can get a three-pack of Eero routers for just $160, one of the best price points we've ever seen on a mesh Wi-Fi system.

Depending on how you arrange them, three routers could cover a home of up to 5,000 square feet with fast, consistent internet. This deal is $90 less than the usual price for this bundle, and we wouldn't be surprised if it sold out before the holiday weekend was over.
