We have 2 WISMs here and one WLAN connected to interface "Int1" and they are working fine. For now, we want to expand the IP addresses of this SSID, so we created several VLANs as well as some interfaces in WLC and created a interface group to contain all the interfaces (includes to original "Int1"). When we tried to change the interface to the interface group under that SSID, we found that the clients lost the connection. We even tried to put only the "Int1" in the interface group. Is there any way to expand the IP addresses without network outage? Thanks!
