Hi.
I tried to need upgrade firmware of WLC to 7.6.00.To avoid long hour outage, I was using image pre-download firmware upgrade method to all access points.There are 99 AP in total & one site has issues 5 Aps. There are 13 x 3600 APs in this site. Out of 13, 5 x APs are not able to push new firmwareFrom my troubleshooting, I found that when I start pushing new firmware to AP, Secure tunnel between WLC and AP drops.
Please guide me to resolve this issue.
Thanks

SSH into the AP and issue a show flash and see if you have enough space. You might have files like crash logs or event logs or even old images that is taking up space and not allowing the AP to upload any new images. You need to free up space by removing those files.

Try to pre-image download again. If not, you can always use the archive download-sw command from SSH of the AP.

Something is not right here. You've got HUGE free space. Exactly what is the current version of your firmware?
Early versions that first supported the pre-download had a bug (if I remembered correctly) that behaves exactly what you are seeing now. The only recourse was to reboot the controller.

Yeah there is enough... Nothing is 100%, so the work around is to out the image on the AP itself. That's what I would do. Why is it not working... Who knows, but I wouldn't waste any time to be honest. Upload the image using the archive command and call it a night:)
