I can try, but I don't know when I will answer as the beast is at home and I'm not yet.
Post some questions and I will do my best. The AP900 has just had a new fw release that has some new features, the best one is that you can turn off the rather bright LEDs unless you're trying to do diagnostics.
It is only a 802.11n capable device, doesn't do 802.11ac.
