A few months ago I installed two new AP3825i and it came with loaded. When I adopted it into my network it failed to upgrade to my controller version. I never worried about it, figured on the next controller upgrade it would fix itself- I was wrong.

I upgrade to tonight and these two AP3825i APs failed to upgrade. I have a bunch of other AP3825i that took the update without issue.

I’m not sure where to begin.

Have a look at this.

That’s quite fresh software. Looking for any clue in ap.log on the AP is a good idea here.


Hope that helps,
