Thanks for your reply .. After updating the system to 15.2 somehow we lost all encryption and the APs was showing Encryption to None so if you can advice about this problem please
Thanks in advance
Hi Ahmed,
When you say you lost encryption, do you mean your AP is no longer configured for encryption, or you are unable to turn on the encryption settings?
As Dave mentioned, upgrading to 15.2 or later will cause DES encryption to no longer be available, and will show warnings indicating that DES is confgured, but not operating, and asking you to change encyrption to either AES or None to proceed. If you were using AES128 encryption, nothing should change after upgrading.
Please see this knowledge base article for a proper upgrade plan: http://community.cambiumnetworks.com/t5/PMP-FAQ/15-2-AES-256-Encryption-FAQ/m-p/85930#M306
Can you provide some more information about what exactly your AP and SM encryption settings are, perhaps with screenshots of the Configuration-->Security tab?
Thanks,
