I have a 4402 WLC with 44 Cisco Aironet 1240 AP's in lightweight mode and my wireless networks WIFI-GUEST, WIFI-PROV and WIFI-CORP01 works propertly. Recently we installed an Aironet 1600 Series in standalone mode and we can connect to WIFI-GUEST and WIFI-PROV without any problems, but for connecting successfully to WIFI-CORP01 we have to change the SSID on this AP (for example WIFI-CORP02). ¿Why is this happening? ¿How can I solve the problem and use the same SSID for the whole network?
Thanks for your help!!
