You ought to be able to define the same SSID as used on your Cisco wifi router, on a Ruckus standalone mode AP.
How is your Ruckus AP configured, under Configuration::Internet?
If you leave the Management VLAN as VLAN 1, you will be on whatever subnet is advertised by the Cisco router. We recommend to assign a static IP address (ie your 192.168.0.22), with the Cisco router IP address as the IPv4 default gateway. Start there. With a static IP assigned to the Ruckus AP (and use an IP outside of the Cisco DHCP scope), is your laptop able to ping the AP?
Assuming you can access the AP with a static IP address, you would define your SSID under the Configuration::Radio 2.4G or Radio5G, and under the SSID tab, use the Packet Forward method of "Bridge to WAN". Clients who successfully authenticate by your specified WPA PSK or other, will then get their DHCP requests dropped onto the Ethernet, where they should be answered by your Cisco DHCP server.
Your Configuration::Ethernet Ports, should both also be specified with "Bridge to WAN" on untagged VLAN 1.
If you can connect your Mac Mini into an extra LAN port of the Cisco router, do you get an IP from it's DHCP server? Can you ping the Ruckus AP?
If you connect your Mac Mini into the second LAN port of the 7352 AP, do you get an IP from the Cisco router? Can you ping the Ruckus AP? Can you ping the Cisco router? Can you ping www.yahoo.com? (to test DNS)
This troubleshooting will help to narrow down the area(s) needing further investigation.
