Summary: This is a Dual Band, but not a simultaneous Dual Band AP. This AP can operate in either NG (2.4GHz) or NA (5GHz) mode, but not simultaneously in both modes as it has a single radio, and not dual radios. What's more! It is a 3x3 (streams, not chains) offering upto 450Mbps of data rate. Quite fast, and trouble free. I had to frequently reboot my previous Netgear AP, but this one is steady and I hadn't rebooted it in several months, and it is still going great.
