By implementing 128 bit WEP encryption, the data becomes less susceptible to unauthorized intrusions.


Open system/authentication and/or ACL implementation does not provide adequate network data security.

To enable the 128 bit WEP encryption security parameter:
  1. Select Special Functions from the access point main menu.
  2. Select the Configure Authentication, an Encryption menu option.
  3. Ensure the Pre-shared Key is enabled.
  4. Ensure 128 bit is selected.
  5. Select Configure WEP from the Configure Authentication and Encryption screen; the WEP Encryption Configuration will be displayed.
  6. Select WEP/KeyGuard Key Maintenance.  The Encryption Key Maintenance screen will be displayed.
  7. Either enter a PassKey (optional) as a plain text representation of the WEP keys.
  8. Or if not using a PassKey, select the desired key and enter the new value.
  9. Select [F1] to both save and display a confirmation prompt.
  10. Select [F2] to save change to all access points of the same ESSID (the “save to all AP’s” option is only used with the same hardware and firmware platforms).
