NETGEAR® ProSAFE® WC7520 Wireless Controller Configuring a Dedicated VLAN Using the Internal DHCP Server APPLICATION NOTES
INTRODUCTION Most business environments require hybrid wired and wireless networks to maximize productivity and effectively manage diverse traffic needs. It is often desirable to partition different traffic types into separate, independent virtual local area network (VLANs) using different IP subnets for clients that are accessing the guest and staff networks.
WC7520 192.168.250.3 PC 192.168.250.4 In this scenario we’re assuming that there is already a wired corporate network set up on VLAN 100, 192.168.100.0/24 Internet/Corporate Router 192.168.100.1 Switch 192.168.100.2 M4100 Switch Step 1 – Add VLAN 250 for Wireless Select Configuration – Routing – VLAN – VLAN Routing Wizard to add the VLAN and IP address, and to enable routing.
WC7520 Step 1 – Configure IP Select Configuration – System – IP/VLAN. Connect to the default IP of the WC7520, 192.168.0.250. Change the IP address; we’ll use 192.168.250.3/24. The default gateway will be the switch on 192.168.250.2 and the DNS server will be the router on 192.168.100.1. You’ll have to change the IP now, then reconnect to the WC7520 on its new IP address.
Step 2 – Configure the SSID Select Configuration – Profile – Basic – Radio. We will call this wireless network WirelessLAN. We won’t use any encryption for now.
Step 3 - Configure the DHCP scope Select Configuration – System – DHCP Server. Select Add to add a DHCP server for your Wireless LAN. Again, the default gateway will be the switch on 192.168.250.2 and the DNS server will be the router on 192.168.100.1. The range will exclude the static addresses, in this case we will use 192.168.250.100-192.168.250.200. Step 4 - Plug in your Access Point to port 4 Make sure the Access Point is on Factory Defaults, and wait until it’s fully booted up.
Step 5 - Discover and add your AP Select Access Point – Discovery Wizard Choose Factory Default State, then Same L2 network. You should find your Access Point on its default IP address. Select it, and select Add. Leave the password field blank and press “ADD”. Wait until you see “Connected” in the Status column, this will take a few minutes.

Router Step 1 – Add static route to new Wireless LAN The router needs to know about this new IP subnet, so we will need to add a static route. This is done by selecting Network Configuration – Routing on a NETGEAR firewall. NOTES This guide is based on a factory default WC7520, running firmware 2.5.0.5_3215. SECURITY Security is outside of the scope of this document. ACLs can be implemented on the switch to limit traffic.
