Bests & Worsts Reviews from Amazon

Hardware-wise this is a 5-star great router, esp for challenging small-business environments. Except there's a glaring software security issue: the Guest networks are NOT isolated from the private networks! L2 level access is wide open, which of course is a deal-breaker. A guest can use Fing and in 2 seconds see every device on your private network, read their MAC addresses, discover services and printers, manage private routers, etc. Guests can even receive DHCP leases from private internal servers! The only thing that's blocked (using a software filter) is most of the Level3 IP traffic. Sure, pings and data packets may get blocked, but any simple network intrusion scanner has a field day. Yes, my device is configured correctly, set as a Router, properly secured, etc. I did a little digging in Netgear forums and discovered this is a long-time (over 5 years) and still currently known problem for many of Netgear's products. (search for "netgear guest isolation not working"). This flaw stems from Netgear oddly using the same subnet for guest and private, which popular competitors don't do. I can't fathom why Netgear hasn't yet resolved this. Again, this really is a great piece of hardware, providing fast rock-solid connections for 50-100 users in a challenging multi-level concrete structure. Better than any others we've used. But the advertised security of Netgear's guest network isolation simply does NOT work. Be aware of this security weakness and plan accordingly.
