Currently we have two Cisco Aironets (AP1121G) using WEP for our default network with only one SSID. What I would like to do would be to have one SSID for our staff which uses WPA, a Guest SSID on a separate VLAN which also uses WPA and a third SSID on a separate VLAN with WEP for legacy devices. We currently don't have any RADIUS server configured and both wireless devices are connected using Cisco 3750 switches.
Ideally each SSID would correspond to a different subnet, we currently only have one DHCP server, is this possible? looked at the idea of using IP helper address before to broadcast across different subnets.
Can someone advise please.
