We have almost 100 Cisco model 2802E APs in production, and (having some spare time) looked further as to why, every couple of months, we’d notice that a 5Ghz interface was down, and, we would have to reboot each AP, to get the slot 0 interface back up. Note that this AP has a dual 5Ghz capability, where the controller uses FRA (flexible radio assignment), to reach out to the AP, and change the radio in slot 0, from 2.4Ghz to 5Ghz radio. Also, since the 2802E does not have the DART adapter cable connected to the AP, the slot 0 interface is only capable of having a 2.4Ghz radio.
So, it turns out, the controller is attempting to use FRA on the 2802E AP (sans DART adapter), and … leaving the slot 0 interface DOWN. Details at can be found at bug ID CSCvt77420. No workaround … but instead of rebooting AP, I have since gone to each AP, and changed the out-of-the-box setting from “radio role assignment”=Auto to Manual / 2.4Ghz radio (for slot 0.) For time saving, one can create a Lightweight AP Template in PRIME, on the 802.11a/b/g/n tab, to Select Slot (0) and Radio Role Assignment.
