    H A P T E R Universal Plug-and-Play (UPnP) This chapter introduces the UPnP feature in the web configurator. 19.1 Introducing Universal Plug and Play Universal Plug and Play (UPnP) is a distributed, open networking standard that uses TCP/IP for simple peer-to-peer network connectivity between devices. A UPnP device can dynamically join a network, obtain an IP address, convey its capabilities and learn about other devices on the network.

  • Page 184: Upnp And Zyxel

    All UPnP-enabled devices may communicate freely with each other without additional configuration. Disable UPnP if this is not your intention. 19.2 UPnP and ZyXEL ZyXEL has achieved UPnP certification from the Universal Plug and Play Forum UPnP™ Implementers Corp. (UIC). ZyXEL's UPnP implementation supports Internet Gateway Device (IGD) 1.0.

    P P E N D I X Wireless LANs Wireless LAN Topologies This section discusses ad-hoc and infrastructure wireless LAN topologies. Ad-hoc Wireless LAN Configuration The simplest WLAN configuration is an independent (Ad-hoc) WLAN that connects a set of computers with wireless stations (A, B, C). Any time two or more wireless adapters are within range of each other, they can set up an independent network, which is commonly referred to as an Ad-hoc network or Independent Basic Service Set (IBSS).

  • Page 276: Figure 172 Basic Service Set

    Appendix E Wireless LANs Figure 172 Basic Service Set An Extended Service Set (ESS) consists of a series of overlapping BSSs, each containing an access point, with each access point connected together by a wired network. This wired connection between APs is called a Distribution System (DS). This type of wireless LAN topology is called an Infrastructure WLAN.

  • Page 277: Figure 173 Infrastructure Wlan

    Appendix E Wireless LANs Figure 173 Infrastructure WLAN Channel A channel is the radio frequency(ies) used by IEEE 802.11a/b/g wireless devices. Channels available depend on your geographical area. You may have a choice of channels (for your region) so you should use a different channel than an adjacent AP (access point) to reduce interference.

  • Page 278: Figure 174 Rts/Cts

    Appendix E Wireless LANs Figure 174 RTS/CTS When station A sends data to the AP, it might not know that the station B is already using the channel. If these two stations send data at the same time, collisions may occur when both sets of data arrive at the AP at the same time, resulting in a loss of messages for both stations.

  • Page 279: Table 115 Ieee 802.11G

    Appendix E Wireless LANs If the Fragmentation Threshold value is smaller than the RTS/CTS value (see previously) you set then the RTS (Request To Send)/CTS (Clear to Send) handshake will never occur as data frames will be fragmented before they reach RTS/CTS size. Preamble Type A preamble is used to synchronize the transmission timing in your wireless network.
  • Page 280 Appendix E Wireless LANs • User based identification that allows for roaming. • Support for RADIUS (Remote Authentication Dial In User Service, RFC 2138, 2139) for centralized user profile and accounting management on a network RADIUS server. • Support for EAP (Extensible Authentication Protocol, RFC 2486) that allows additional authentication methods to be deployed with no changes to the access point or the wireless stations.
  • Page 281 Appendix E Wireless LANs In order to ensure network security, the access point and the RADIUS server use a shared secret key, which is a password, they both know. The key is not sent over the network. In addition to the shared key, password information exchanged is also encrypted to protect the network from unauthorized access.

  • Page 282: Table 116 Comparison Of Eap Authentication Types

    Appendix E Wireless LANs PEAP (Protected EAP) Like EAP-TTLS, server-side certificate authentication is used to establish a secure connection, then use simple username and password methods through the secured connection to authenticate the clients, thus hiding client identity. However, PEAP only supports EAP methods, such as EAP-MD5, EAP-MSCHAPv2 and EAP-GTC (EAP-Generic Token Card), for client authentication.
  • Page 283 Appendix E Wireless LANs Key differences between WPA(2) and WEP are improved data encryption and user authentication. Encryption Both WPA and WPA2 improve data encryption by using Temporal Key Integrity Protocol (TKIP), Message Integrity Check (MIC) and IEEE 802.1x. In addition to TKIP, WPA2 also uses Advanced Encryption Standard (AES) in the Counter mode with Cipher block chaining Message authentication code Protocol (CCMP) to offer stronger encryption.

    Appendix E Wireless LANs 26.8.2 WPA(2)-PSK Application Example A WPA(2)-PSK application looks as follows. 1 First enter identical passwords into the AP and all wireless clients. The Pre-Shared Key (PSK) must consist of between 8 and 63 ASCII characters (including spaces and symbols).
