NWD210N User’s Guide 37 C HAPTER 3 Wireless LANs This chapter provides backgro u nd inform ation on wireless Local Area Networks. 3.1 Wireless LAN Overview The following figure pro vides an exampl e of a wireless network with an AP . See Figure 3 on page 23 for an Ad Hoc network example.
Chapter 3 Wireless LANs NWD210N User’s Guide 38 Like radio stations or television channels, e ach wireless network uses a spec ific channel, or frequency , to send and receive information. • Every device in the same wireless network must use security compatible with the AP or peer computer .
Chapter 3 Wirel ess LANs NWD210N User’s Guide 39 Y our NWD210N allows you to configure up to fo ur 64-bit, 128-bit or 152-bit WEP keys. Only one key is used as the default key at any one time. 3.2.1.1.2 Authentication T ype The IEEE 802.1 1b/g standard describes a simple authentication method between the wireless stations an d AP .
Chapter 3 Wireless LANs NWD210N User’s Guide 40 If both an AP and the wireless clients suppor t WP A2 and you ha ve an external RADIUS server , use WP A2 for stronger data encryption.
Chapter 3 Wirel ess LANs NWD210N User’s Guide 41 3.3.2 PIN Configuration Each WPS-enabled device has its own PIN (Personal Identificatio n Number). This may either be static (it cannot be chang ed) or dynamic (in some devices yo u can generate a new PIN by clicking on a button in th e configuration interface).
Chapter 3 Wireless LANs NWD210N User’s Guide 42 Figure 20 Example WPS Process: PIN Method 3.3.3 How WPS Works When two WPS-enabled devices connect, each de vice must assume a spe cific role.
Chapter 3 Wirel ess LANs NWD210N User’s Guide 43 Figure 21 How WPS works The roles of registrar and enrollee last only as long as the WPS setup process is active (two minutes). The next time you use WPS, a different device can be the registrar if necessary .
Chapter 3 Wireless LANs NWD210N User’s Guide 44 Figure 22 WPS: Example Network S tep 1 In step 2 , you add ano ther wireless client to the network. Y ou know that Client 1 supports registrar mode, but it is better to use AP1 for the WPS handshake w ith the new client since you must connect to the access point anyway in order to use the network.
Chapter 3 Wirel ess LANs NWD210N User’s Guide 45 Figure 24 WPS: Example Network S tep 3 3.3.4 Limit ations of WPS WPS has some limitati ons of which you should be aware. • WPS works in Infrastructure networks on ly (where an AP and a wireless client communicate).
Chapter 3 Wireless LANs NWD210N User’s Guide 46 Y ou can easily check to see if this has happ ened. WPS works between only two devices simultaneously , so if another device has enrolle d y our device will b e unable to enroll, and will not have access to the network.
