We have a AIR-WLC2106-K9 who suddenly stops working. We cant access it trough the web GUI or console, we cant even ping it. All leds stock on green (all of them), and the service go down. After restarting the WLC, it works fine but after 3 to 5 days, it fails again.
It is using 18.104.22.168, but we don't want to go up to 6 cause we are using this image as the standard in all out WLC. We have like 10 of these WLC, all with same image and same config, but we have no problems with anyone else.
I'm adding the sh tech.
