See below tips and guides, it would be big help if you pick this Cisco Wireless Express Mobility System Solution.

 

Simple we divided three VLANs for few reasons such as security and reduced unnecessary traffic on each network boundary

VLAN 20 = Guest Network (Who can access Internet / but not Intranet)
VLAN 30 = User Network (Who can access Internet and Intranet)
VLAN 40 = AP-manager Network (Network for Cisco WLC526 and AP521)

There are two ways to configure Cisco 500 Series Wireless Express Mobility gears : GUI and Console mode.

Cisco recommends a using "Cisco Configuration Assistant" for initial configuration, but I preferred to use console mode, not just b/c I am used to it. Some of terminology used in the box easily make you confused, while you are setting up WLC(Cisco Wireless Controller) 526.

Management VS. AP-manager interface : Very important to know that Management interface means which you can access WLC 526 for modification , creation and apply. But AP-management interface is not for user. It is for AP521. The interface is communicating to Cisco AP521s. You cannot access the Cisco WLC526 using AP-manager interface IP.

Cannot change VLAN tagging info by GUI configuration mode : If you didn't specify VLAN number, while you were configuring the box using either GUI or console mode, you cannot modify VLAN tag later. Make sure configuring VLAN numbers.

DHCP server for all VLANs : Don't forget DHCP server prepared for VLAN 20 and VLAN 30. VLAN 40 will automatically discover Cisco AP521s. (IP will be assigned within a given network range). See below physical network map.

Look closer actual Cisco AP521 is physically connected to Switch. On your switch setting, you must configure trunk mode a port to connect Cisco WLC526.

Guest traffic flow :
Cisco AP521 --> Cisco WLC526 --> Tagged VLAN 20 (192.168.20.x/24) --> Router --> WAN --> Internet.
