By connecting an external network (Internet) to a private 
network at home, a router allows one external network line 
to be shared by multiple network devices.
Router functionality can be found inside DSL modems, 
wireless LAN access points, and other network devices.

In a Universal Plug and Play environment, this is the 
protocol used to discover network devices.
If you enable SSDP on the AIBO

®

 Entertainment Robot 

ERS-7, then you will be able to search the network for the 
AIBO robot ERS-7 using the “AIBO WLAN Manager 2”.

Also referred to as “Access Point ID”, “Group Name”, and 
“ESSID”.
When a wireless LAN-ready device performs wireless 
communication in Infrastructure mode, it uses a string called 
an SSID as its wireless network identifier.
The SSID on the AIBO robot should be set to the same SSID 
as on the access point.
The SSID can be a maximum of 32 characters. Only 
alphanumeric and punctuation characters are allowed.

While an IP address is composed of 4 numbers ranging from 
0-255 (see “IP Address”), in order to manage them more 
efficiently, IP addresses are split into network portions and 
host portions. This setting is called the subnet mask.
A subnet mask defines the network portion as those bits that 
are set to ‘1’.
Example:When a subnet mask of 255.255.255.0 is set for a 

device with an IP address of 192.168.1.1,

192.168.1

Network portion

Host portion

One type of communication method (protocol) used by 
network devices (such as PCs) to communicate.
TCP/IP is the most widely used protocol on the Internet.
This wireless LAN card communicates over TCP/IP.
When communicating over TCP/IP, a number called an “IP 
Address” is needed to distinguish among devices.
