Hi, we have 9 WAP4410N with PoE in our network. They were purchased on August. We found that very often in a week, they stop responding to any clients so they cannot get IP addresses, but we can ping the devices and enter the administration page. The only solution is to reboot the AP. I found some references to the same problem in the Cisco Forums and even some bad recommendations in Amazon.com about these APs, but now is too late and we need to found a solution.
We upgraded to firmware 2.0.3.3 but problem remains. We are completly sure that IP and DNS configurations are fine and that our switches and DHCP servers work fine, too. We have in the same LAN, APs 3COm from the 9150 series with no problems. These 3Com APs use the same network services that the 4410.
Currently we are testing the Force LAN to 100 Mbps option and using mixed encryption algorithms (AES and TKIP) because at the begining, we were only using AES. But, I feel that it is not a smart procedure because it is not based on any real fact; it is, may be a desperate choice.
In order to administer those APs, we normally connect at the night so we don´t affect anyone on the network. However, when I check the administration page, I can see that the utilization rate in all the APs is always more that 40%, and I am sure, nobody is using the AP at the night. Wierd. In a normal day, no more than 20 clients are connected to each AP.
Logs have no valuable information to use in order to find a solution.
So, any ideas or help would be much appreciated.
