Mikrotik as AP with WPA2 security. If both TKIP + AES are enabled, then lamp is able to connect during setup routine and works normally, also application works. After power cycle it's not trying to reconnect anymore according to mikrotik logs.
Problem gets resovled, if TKIP is disabled in security profile.
Why don't lamp simply connect with AES, if it doesn't like TKIP?
It's firmware v 1.5.5_0180
