hello,
i bought last eeb a metal 5shpn it is an acces point.
i've always same problem like insubject:
"unicast key exchange timeout".
i try to setup security profile in wpa psk, wpa2 psk .....
but nothing probable routeros issue??

wath you can suggest me
tnks in addance

ps. i alredy send email to mikrotik technical support awaiting answer.

The problem are on aes-ccm unicast key exchange timeout, set group key timeout more than the default 5 min.
If you want solve this problem, use only MikroTik hardware and do not mix.

Mikrotik also designs WiFi AP's and hence we cannot restrict the use of Mikrotik devices at client level as well.

this issue is still not resolved at that WiFi AP level....
