I have 1 WLC 5508, software version 188.8.131.52 and 20 AP (AIR-CAP1602I-T-K9) installed on the head office and 15 AP x 3 Branch office.
The roaming problem occurs at all sites, even using 2.4 or 5 ghz and with any devices, laptop, mobile, tablets.
Sometimes the connection drops, other times I need to disconnect and connect again to the WLAN.
Sometimes I have poor signal, even if I move bellow another AP, the roaming doesn't occur.
Troubleshootings that I did:
Site survey using Airmagnet Pro, there is some others SSID on same channels (2.4 GHz, 5 GHz) Debug tracking an user mac address, but nothing was found. DCA channels config to default, DCA channel list remains 1,6,11.
Additional information: This issue also occurs using 802.1x or WPA PSK.
You need to make sure your using WPA/TKIP of WPA2/AES, not a mix of either or both at the same time. Try that first as you have no issues with other authentication methods, so no need to change anything else.

The 1st installment is a table of advanced filters. More filters will be added as time allows.
