Verdict
This NETGEAR EX6400 offers solid coverage and straightforward setup, making it a popular choice for general WiFi extension. If you're after a simple, reliable extender that supports many devices, it might suit your needs — *but* beware of potential durability issues and complicated support policies. For more consistent performance, especially in demanding gaming or streaming environments, you might want to consider higher-end options like the Orbi series, which many reviews mention as more durable and stable over time.
