Good day all.. i just purchased 2 IAP 335's and pluged one in and expected it to autojoin as usual to my current group. i currently have IAP 105's, 135's and 225's and they all seem to join fine. however the 335 seems to be having a problem joining. the power light blinks green but never seems to ready. all other IAP's are on firmware 6.4.2.6-4.1.3.0_54915.. the 335's are on 6.5 .. is there something i need need to do to get the 335 to join?
