problem cisco 2504

[Andrea Salvan]

I have much problem with mi cisco 2504. I update software version 7.4 for use 1600 ap series. I have 5 license. I create a wlan but after a short time disappear from the wireless sensing. The access point also records disappear from the controller. I also have difficulties to register the access point. I see that reset downloading the configuration and then disappear without reappearing. Help me!!

So you are saying that your AP will disappear from the WLC list? 

If this is so, and your APs appear, can you check if your APs disappear because they rebooted?  If they are or they do, then I'd be looking at how the APs are getting their power.  

If you have a Cisco Catalyst switch, check to see if your switch support TDR function.

One AP is out. LINKSYS SRW2048 or CISCO SLM2024, but I also have other problems to the desired configuration.
