Hello Alexander

If you are still experiencing issues I would suggest opening a case with GTAC so we can look through the logs etc.

Did you turn it on? Did it help you? Let us know when you can 🙂

[Alexander7]

Hi,
yes, rekey interval set off. I forget about it(

[Joseph_Burnswor]

Do you have a rekey interval set on your WLAN privacy? If you do not, the session can become stale until it reconnects after the reboot
