Hi,
yes, possible.
Put 192.168.10.0/24 network in VLAN 10
Put 192.168.20.0/24 network in VLAN 20
Map SSID Crew to VLAN 10
Map SSID Client to VLAN 20.
You have to configure VLANs at switch and within wireless infrastructure (controller or VC if using instant APs).
Ports of APs have to be tagged correctly if instant. otherwise ports of controller.
If you need traffic between crew server and client server, some type of router (or firewall) will be needed.
Either put wireles management in crew vlan or create a third management vlan.
Kind regards, Jörg
