I have a WLC 4400 running ver 126.96.36.199. The LAP is a 1242AG-A-K9. I am getting this error message on the wireless controller log when I try and use my Symbol 9060 RF units the message is:
WEP Key decrypt error. Station MAC Address is 00:a0:f8:ba:b5:36, Base Radio MAC is 00:19:a9:0f:d7:90 and Slot ID is 0.
My setup is WPA using 802.1x and the units do authenicate but then after a random period the users lose their sessions. Actually doesnt seem to matter whether I am using WPA or WEP, i still drop. I havent had this problem with the fat APs. Any ideas?
