I have installed for a client several 4410n WAP and encountered the problem exposed in this thread. I have noticed that a new firmware (220.127.116.11) has been released this month (september) and in its release notes there is no mention concerning the problem. I will tomorrow upgrade those APs hoping that it will fix the problem.
I thought that when there is critical problem like that, a company like Cisco would normally do its best to resolve it ASAP, but I must be naive ..
I am really disapointed if the problem is not solved, because I will lose an important client as also I will have to replace the WAP with others of another brand without having my money refunded .. It is a real shame ..
For a long period I was trusting Cisco to be the Leader in network equipments now I feel slightly different ..
Well I hope, that someone will reply and solve.
