Mesh routers have, uh, routed the rest of the Wi-Fi industry over the last couple of years, and the popular Luma system is on sale for an all-time low $150 for a pack of three routers with promo code 20OFFLUM.
Rather than relying on a single base station to fill your entire home with Wi-Fi, Luma uses three of them to create a dense mesh of connectivity, making dead zones a thing of the past. Plus, they include some neat software for parents like automatic content filtering and daily time limits for specific devices.
