Analysis:

Having only 5Ghz gear installed on various sites I cannot really test this, someone with spare 2Ghz gear is welcome to do so. From the reports here at times it seems that they finally nailed bug #1. I must also stress that for the last 3-4 months I've fell a 'victim' to what appears to be an effect of whatever bug is raised in #4 where the AP would however fail to start transmitting in high interference environments. One can only hope that this will be rolled out onto the 5Ghz gear and will indeed be a solid release at that.

Please do share your feedback with your setups and the new f/w below.
