[. . . ] This field displays the signal strength of each wireless device. Click Scan to search for available wireless devices within transmission range. Click Connect to associate to the selected wireless device. Click an entry in the Available Network List table to display the information of the selected wireless device. This field displays the network type (Infrastructure or Ad Hoc) of the wireless device. This fields displays the network standard (802. 11g or 802. 11b) of the wireless device. This field displays the channel number used by each wireless device. This field shows whether data encryption is activated (WEP, WPA, WPA2, WPAPSK or WPA2-PSK) or inactive (DISABLE). This field displays the MAC address of the wireless device. This field displays the time when the wireless device is scanned. 3. 2. 1 Connecting to a WLAN Network Follow the steps below to connect to a WLAN network using the Site Survey screen. 1 Click Scan to search for all available wireless networks within range. 2 To join a network, click an entry in the table to select a wireless network and then click Connect. 3 If the WEP encryption is activated for the selected wireless network, the Security Settings screen displays. You must set the related fields in the Security Settings screen to the same security settings as the associated wireless device. Refer to Section 3. 2. 2 on page 34 for more information. Otherwise click the Back or Exit button and connect to another wireless network without data encryption. 4 Verify that you have successfully connected to the selected network and check the network information in the Link Info screen. 3. 2. 2 Security Settings When you configure the G-302 v3 to connect to a network with wireless security activated and the security settings are disabled on the G-302 v3, the screen varies according to the encryption method used by the selected network. 34 Chapter 3 ZyXEL Utility Configuration ZyXEL G-302 v3 User's Guide 3. 2. 2. 1 WEP Encryption Figure 15 Security Settings: WEP The following table describes the labels in this screen. Table 6 Security Settings: WEP LABEL WEP Authentication Type Pass Phrase DESCRIPTION Select 64 Bits or 128 Bits to activate WEP encryption and then fill in the related fields. Refer to Section 2. 3 on page 29 for more information. Enter a passphrase of up to 63 case-sensitive printable characters. As you enter the passphrase, the G-302 v3 automatically generates four different WEP keys and displays it in the key field below. Refer to Section 2. 2. 1 on page 26 for more information. At the time of writing, you cannot use passphrase to generate 152-bit WEP keys. [. . . ] If they do not match, it is assumed that the data has been tampered with and the packet is dropped. By generating unique data encryption keys for every data packet and by creating an integrity checking mechanism (MIC), with TKIP and AES it is more difficult to decrypt data on a Wi-Fi network than WEP and difficult for an intruder to break into the network. The encryption mechanisms used for WPA(2) and WPA(2)-PSK are the same. The only difference between the two is that WPA(2)-PSK uses a simple common password, instead of user-specific credentials.
