We are beginning to receive reports that clients are being dropped after 15 to 20 minutes of being connected. I have taken a look and I cannot see any configuration regarding connectivity timeouts when client's and APS.
We are using Cisco 4404 wireless controllers/WCS and Air-lap1131AG AP's
A group of three students reported the issue togther yesterday. What I find odd is that they could not reconnect without having to perform a repair to their wireless adapter in their laptops.
