when will we get the upgraded firmware for AP902 , AP900 just had 1.2 and had new features which work well

I have 9 x AP900 airstations in 2 seperate locations , and 3 x AP902, 1 of which is at home and fine its not as good as my old apple extreme 2nd gen the issue is as follows for my home AP902

Ring Chime ( 2.4G - doesn't like channel 11-13 - Texas Instruments chip-set ) even when i set the right channel looses connection constantly threw out the day tried reconnecting etc but once i set it to apple extreme has been working 100%
Withings AURA crashed during updates when setting up trying to use AP902 tried 3 times but once i changed to Apple extreme worked 100%

So does AP902 have issues or a setting i need to check etc
