This article from BGR.com compares Wi-Fi mesh networks and range extenders, outlining the pros and cons of each to help you decide which is best for your needs.
wi-Fi Mesh Networks:
* Pros: seamless Wi-Fi coverage throughout a property,centralized management.
* Cons: More expensive than range extenders (even budget systems can exceed $100), require backhaul (communication between nodes) - often needing a wired connection which can be tough to set up if Ethernet isn't readily available.
Wi-Fi Range Extenders:
* Pros: Affordable, work with existing routers, easy to set up.
* Cons: Add latency, slower than mesh systems (bandwidth is used communicating with the router), create a separate Wi-Fi network which can cause devices to connect to weaker signals, requiring manual switching.
In essence:
* Choose a mesh network if: You need extensive, fast, and seamless coverage, and are willing to invest more and possibly deal with wiring.
* Choose a range extender if: You need a budget-friendly solution and don't mind some performance trade-offs and potential connection management.
