I have this weird problem on which I am breaking my head from the last couple of days.
We have a wireless infrastructure with WLC 5508, 1252 1242 & 3602 AP. The IOS on the WLC was 184.108.40.206. There was an issue wherein if an unauthorized user wants to access the network, he would get in without any authentication. This was a bug and the same was rectified in the IOS version 220.127.116.11.
After the upgrade every thing hasd been working fine. There is an issue with the 1242 AP. These AP (1242) worked fine after the upgrade but after some days 3 AP (1242) stopped working. They could could be seen as registered in the WLC but no users can connect to these AP's. I have tried converting the AP to autonomous and upgrading it to LAP but to no success.
What code do you have on the WLC now? Also what code are you uploading to the access point? Your saying that the ap works fine for a few days and then you have to reboot it or the ap isn't joining the WLC?
The code as of now in the WLC is 18.104.22.168. The code uploaded in the IOS is c1240-k9w8-mx.124-25E.JAL2
Like I said the WLC was upgraded to 22.214.171.124 about 20 days ago after which the issue has arised. The AP did work for a few days after the upgrade and then it started to give this problem. The issue here is the AP is registered with the WLC but no users can connect to it.
I have deleted the IOS from the flash. converted the AP to autonomous mode and then converted to LAP again but the problem still remains the same i.e AP is registered with the WLC but no users can connect to it.
Well when I have to redo an AP, I would clear the nvram and delete all the images from the access point and then upload the rcv image. You do that or else the issue will stick with the AP. If after you do this and the issue continues, then open a tac case as it could be an issue with the AP or a bug on the code for that model AP.
