I saw this error when i tried to update a single AP, and now that i selected a bunch of AP’s, they are all showing this error message.
“the cli interface wifi0 radio profile radio_ng_ac0 execute failed, caused by: unknown error”.
The error may have been there prior to the change i made, however, this is what i did: I updated the passphrase for our guest SSID, clicked Update (Delta Update), and after a few minutes I get an error under Updated that states Device Update Failed. When i hold my mouse pointer on it, i then get the full error of:
the cli interface wifi0 radio profile radio_ng_ac0 execute failed, caused by: unknown error
To test, I went over to an AP that I could reboot (by pulling its PoE network cable), which I did. I gave it a full minute, plugged it back in, went back to my desk and did a refresh. That AP looked good, the error was gone. BUT then a while later that Device Update Failed message was back.
I have a mix of AP650 and AP1130’s running 10.0r5 and 8.2r4.
Ive updated all the AP’s fairly recently (after creating floor plans and clicking on Update), and didnt have any kind of problem. All i did this time, was to change the passphrase on our guest wifi (we have three SSID’s one for faulty, one for student and the guest one).
Obviously rebooting the AP doesnt help, and even if it was, its not like i can even reach some of the AP’s, and I dont want to have to reboot the 50+ switches in order to restart all the AP’s.
below is a screenshot (some fields i blacked out):
