I have to deploy 6 access points in a warehouse. I want one of them (which will serve less clients) to act as WDS access point. I've configured local RADIUS server on this AP (WPA + TKIP). I've also configured WDS service on this AP, configured the other APs to participate in SWAN infrastructure. Access points register to WDS without problems, clients authenticate to all APs. However, I did not notice "dramatic" reduction of roaming time when I travel from one AP to another (some packet, especially big, are lost). I tried to enable CCKM in SSID manager window, but after this clients do not authenticate to AP at all. I assume that dramatical reduction of roaming time is provided by CCKM feature. Cleints are CCX certified (Datalogic Skorpio and Intermec CK31 data capture terminals).
