While traditional wifi networks rely on a single router to broadcast a wifi signal, mesh wifi enables multiple routers to work together ensuring every eero connects wirelessly to every other eero in range, on both the 2.4 GHz and the 5 GHz wifi bands. This creates a dense network of connections and many possible paths for traffic to flow. So your network stays strong and is less likely to come to a crawl—even if there’s wireless interference from the neighbor’s baby monitor or heavy gaming traffic in the family room.
