Wireless access points typically have a single Ethernet interface which is connected to another switch or gateway. The access point then provides network connectivity to clients connected via 802.11 a/b/g/n/ac.
In this example the DUT is an 802.11 a/b/g/n/ac wireless access point. CDRouter’s WAN interface (eth1) is directly connected via Ethernet to the DUT’s WAN/Ethernet port. Likewise, CDRouter’s LAN interface (wlan0) will associate and connect to the DUT’s 802.11 a/b/g/n/ac network. A simple CDRouter configuration based on the following assumptions is provided below.
- Management interface IPv4 address: static, 192.168.1.50
- Management interface IPv6 address: not supported
- Wireless security: none (basic wireless)*
- TR-069 support: no
* NOTE: CDRouter supports a wide range of wireless security schemes. Please see this Knowledge Base article for more information.

In this example CDRouter will automatically enable its internal DHCP server using the address range specified by the testvars dhcpClientStart and dhcpClientEnd. Once associated with the DUT, CDRouter’s LAN client will obtain an IPv4 address from within this range. In addition, CDRouter will send NDP Router Advertisements on the WAN based on the address and prefix length specified by the testvars ipv6WanIspIp and ipv6WanIspPrefixLen, respectively. These Router Advertisements will be forwarded by the access point to all associated clients thereby allowing CDRouter’s LAN client to obtain an IPv6 address as well.
- CDRouter or CDRouter Multiport
- CDRouter IPv6 (optional, if IPv6 testing is required)
- CDRouter TR-069 (optional, if the DUT supports TR-069)
- One dedicated Ethernet network interfaces
- One dedicated 802.11 a/b/g/n/ac network interface
- One 802.11a/b/g/n/ac wireless access point
- Allows 802.11a/b/g/n/ac wireless access points to be tested directly
- Can be used to verify the forwarding functionality of an 802.11/a/b/g/n/ac access point for IPv4 and IPv6
- Great for identifying issues between different wireless technologies and security schemes
- Great for verifying the stability and robustness of the access point over time
- Test setup can be expanded by installing multiple wireless clients in the CDRouter host system
- Requires only one dedicated Ethernet interface in the host system (WAN)
