Abstract: A network relay device includes an internal storage unit, an external storage unit having greater storage capacity than the internal storage unit, an accumulation control module and a relay processing module. The accumulation control module compares a receiving rate representative value representing a receiving rate with a sending rate representative value representing a sending rate and stores received data into the external storage unit having the greater storage capacity than the internal storage unit, when the receiving rate representative value is higher than the sending rate representative value. Even when the sending rate from the network relay device becomes a constrained condition of data relay, this prevents reception of data from a device, which sends data to the network relay device, from being constrained by the speed of the sender side.

Abstract: Configuration tasks needed to form a wireless LAN are performed using a simple method while increasing security during configuration. In a wireless network configuration system GH1 including an encryption key setting system LH1, where an access point 20 determines after the power thereto is turned ON that configuration for connection to a wireless LAN has not yet be carried out, the access point 20 activates a restricted receiving mode in which only an initial configuration packet is accepted. A terminal 50 that has sent an initial configuration packet and the access point 20 that has received such initial configuration packet while the restricted receiving mode is active each create an identical WEP key with reference to the data on a CD-ROM 51 or the data in a ROM 12, respectively, and set and register the created WEP key in itself.

Abstract: Upon no completion of setting of a user ID and a password to be sent to a PPPoE server, in response to reception of a DNS request from a client, a communication device of the invention sends back a unique LAN IP address, which is allocated to the communication device, as a DNS reply to the client, regardless of the contents of the DNS request. The client then sends an HTTP request to the received LAN IP address, and the communication device sends back a Web page for entry of the user name and the password as an HTTP response to the client. The Web page for entry of the user ID and the password is displayed on an active Web browser of the client. This arrangement enables the user to readily complete setting for communication in the communication device.
