We've been trying to correct a connectivity problem for a few months now and we are not making much progress. Windows Domain, Wired LAN, Cisco Access Points. The problem is that on occasion, we lost connectivity to our application server from the computers connected wirelessly and hardwired. Mostly the wireless have issues, but wired machines have problems on occasion. We have swapped out the switches and that improved things somewhat. Running a ping test over the wireless yields about a 5% packet loss. This is about 10 ft from one of the AP's w/ nothing in the line of sight. Any ideas on some tools we can use to figure out what the problem(s) are? The switches don't yield up any errors, and the logs on the AP's don't show anything out of the ordinary. Thanks.
