There are several things to keep in mind about the SSID WPA Pre-Shared Key. If you do not have a RADIUS server, select the type of algorithm, TKIP or AES, enter a password in the Pre-Shared key field of 8-64 characters, and enter a Group Key Renewal period time between 0 and 99,999 seconds, which instructs the Router or other device how often it should change the encryption keys Appendix C Upgrading Firmware Appendix D Windows Help TCP/IPShared Resources Network Neighborhood/My Network PlacesAppendix E Glossary Encryption - Encoding data transmitted in a network Router - A networking device that connects multiple networks together Appendix F Specifications Appendix G Warranty Information Appendix H Regulatory Information EN 609 50 Safety An FCC compliant telephone cord and modular plug is provided with this equipment.
