802.11n WLAN ADSL2+ Router WPS Introduction of WPS Although home Wi-Fi networks have become more and more popular, users still have trouble with the initial set up of network. This obstacle forces users to use the open security and increases the risk of eavesdropping. Therefore, WPS is designed to ease set up of security-enabled Wi-Fi networks and subsequently network management (Wi-Fi Protected Setup Specification 1.0h.pdf, p. 8).
802.11n WLAN ADSL2+ Router If those unsupported modes are enforced by users, WPS will be disabled. Under the configuration of every WPS-supported mode, Wireless Gateway has Push Button method and PIN method. For each method, Wireless Gateway offers different security levels included in network credential, such as open security, WEP 64 bits, WEP 128 bits, WPA-Personal TKIP, WPA-Personal AES, WPA2-Personal TKIP, and WPA2-Personal AES. Users could choose either one of the methods at their convenience.
802.11n WLAN ADSL2+ Router Instructions of AP’s and Client’s operations At this state, AP is transparent to users. If users want to configure a station or any device that is capable of being an enrollee, they have to enter device’s PIN into an external registrar and choose an appropriate wireless profile. After the PIN is entered, the external registrar will inform AP this event. AP then conveys the encrypted wireless profile between the device and the external registrar.
802.11n WLAN ADSL2+ Router Push Button Configuration Push Button Configuration Client PIN Number Function Button Regenerate PIN Start PBC Apply Changes Reset Start PIN “Self-PIN Number” is AP’s PIN. Whenever users want to change AP’s PIN, they could click “Regenerate PIN” and then click “ Apply Changes”. Moreover, if users want to make their own PIN, they could enter four-digit PIN without checksum and then click “ Apply Changes”.
802.11n WLAN ADSL2+ Router 3. Plug the Ethernet cable into AP’s LAN port and make sure the IP connection is valid with Vista. 4. Make sure WCN is enabled.

802.11n WLAN ADSL2+ Router to register with some website and get a domain name. When the IP address of the host changes, it just needs to send a message to the website that’s providing dynamic DNS service to this host. For this to work, an automated update client needs to be implemented. These update clients send update messages to the servers whenever there is some change in the IP address of that host. Then, the server updates the entries for that host and replies back with some return code.
