I don't think they announce these things.
Judging by the speed and quality of previous releases (slow and poor quality), I am not holding my breath.
To make things more laughable, last time when I was buying I decided not to cut corners and buy a good AP, so I bought this one and two brand new Buffalo WiFi adapters for "optimal performance of my wireless network" although my existing adapters didn't have any issues (I happened to have a bit fo extra money and though what the heck...).
Fast forward 10 months later and it's at par with the worst AP I've ever had (the previous one, from SMC). Main differences:
a) The Buffalo AP (this one) has more features (but most of which don't work properly, and the overall stability of the unit is pathetic)
b) The few features that SMC had worked (what didn't work was many P2P connections would make it hang, so I had to manually set that limit down to 250 in P2P software)
c) The SMC was 50% cheaper
Are saying you are using the generic firmware, not from Buffalo? If so, which version and where did you get it? I might as well give it a shot and if it doesn't work throw the darn thing to garbage and buy something that works.
