Dear community,
We are running WLAN using WPA2-enterprise with AES & IAS server.
Mostly we are using AP's 1131 and Cisco WLC 4400.
I added on a new location 2 AP 1142G and since the installation I got 3-4 clients having regular disconnections...
Basically they are connected immediately to the infrastructure but after a certain amount of time the Win7 icon is having this yellow exclamation sign, and we can see that the connectivity is gone (however the IP settings seems to be still in place, but ping or network browsing is not possible).
Stopping the WLAN and starting it again solve immediately the issue (via software or via the notebook switch). Normally the problem doesn't resolve by itself.
I was working beside the laptop having the problem with (my own laptop) during the person got 3 disconnections, mine was running like a charm...
I really suspecting a Laptop issue...
We have 85% of the people there working errors free...
Just to summarize what I did :
What I will do again :
So do you know this problem? do you have an idea how to solve it?
Thanks for your help
Regards

It was related to a network card driver version,
In my case it was a known Intel bug,
