I am having disconnections in a WLC4402. The clients are having intermitent connection to APs. I had updated OS from 220.127.116.11 to 18.104.22.168 because of TAC suggestion. The engineer has verified some show comands as well as a debug client. But it seems they do not reflect a big issue. I just captured some packets with wireshark but he's about to analyze it.
This wireless is deployed in the downtown of my city which is a big one. So I've seen some rogue AP and clients around wich might be interefering our network. I performed a site survey and there are not coverage nor power level issues only the rogue signals that I mentioned but they all seem weak.
Does someone could suggest any troubleshooting regarding interference or have any other comments about this issue?
Thanks in advance.
