I've had an older one of these (white) for about 2 years and it performs superbly. Most of my devices use the regular wifi, but I've got a wireless bridge set up to use the 5ghz. My TV, PS3, Wii, and SlingBox downstairs from my router are all perfectly happy with the 5ghz. More than enough bandwidth for everyday use.
(Edit: D'oh - I just remembered that mine is a dual-band D-Link DIR-825 with a DAP-1522 dual-band bridge, not Netgear. Please disregard...)
