ok these IAP 335's are becoming an ordeal.. here is a little background.. i have a mix of IAP 105's 135's and 225's and im trying to add new IAP 335's to the mix which are on firmware 6.5. i was told that i needed to upgrade the firmware on the older devices in order for the IAP335's to join. so i went from version 6.4.2.6-4.1.3.0_54915 to 6.4.4.4-4.2.3.2_54910 on all of my IAP's.. i still find that the IAP335's are still not joining. the power/system light blink green but never go ready.. i cant find the same firmware version for the 335's so i can downgrade them .. i see the firmware for the 325 but not 335.. can anyone help .. thanks
