Using the WBPN Wireless-N Bridge for Phone Adapters Configuration Utility Configuring Wireless Parameters 2 but can slow traffic. Choose a key format (ASCII or hexadecimal) and enter a passphrase or key in the Encryption Key field. Hexadecimal format is more secure. • WPA/PSK or WPA2/PSK-Wi-Fi Protected Access/pre-shared key encryption. Either of these encryption types is more secure than WEP and is recommended instead of WEP. There are two encryption options for WPA/ PSK: TKIP (Temporal Key Integrity Protocol) and AES (Advanced Encryption System). TKIP utilizes dynamic keys and incorporates Message Integrity Code (MIC) to provide protection against hackers. AES uses a symmetric 128-bit block data encryption. WPA2 uses AES-CCMP to perform user authentication, which uses a symmetric 128-Bit block data encryption. Choose the pre-shared key format (passphrase or hexadecimal) and enter the pre-shared key in the field. Hexadecimal format is more secure. STEP 7 Click Apply. Configuring Advanced Settings To configure advanced wireless settings, from the Navigation Menu, choose Wireless > Advanced Settings. You can configure the following settings: Fragmentation Threshold RTS Threshold This value specifies the maximum size for a packet before data is fragmented into multiple packets. If you experience a high packet error rate, you can slightly increase the Fragmentation Threshold. Setting the Fragmentation Threshold too low may result in poor network performance. Only minor reduction of the default value is recommended. In most cases, it should remain at its default value. "Request to send" threshold. If you configure Request to Send/Clear to Send (RTS/CTS) on the WBPN, the RTS threshold is the packet size included in the request. You can configure this value if the WBPN has inconsistent data flow. Only minor reduction of the default value, 2347, is recommended. The RTS Threshold value should normally remain at the default value of 2347. Cisco WBPN User Guide 26
