13.4 Wireless Link Encryption FAQ

13.4.1 Encryption data entry fields are not available

Check that the correct license key has been inserted into the unit. The current license key is
displayed on the 'License Key' data entry page.

13.4.2 Link fails to bridge packets after enabling link encryption

If the wireless link status on the status web page indicates that the link is 'Searching', and you
can browse to the local end of the link but not to the remote end, then check that the same
encryption algorithm and key have been entered at both ends of the link. Failure to enter the
same algorithm and key will result in received packets not being decrypted correctly.

13.4.3 Loss of AES following downgrade

When downgrading (using Recovery software image 05-01 onwards) to an earlier version of
software that does not support AES, the unit will indicate that the region code is invalid. The
user will be required to re-install correct software (supplied when AES key was activated) and
reboot the unit.
