Dirty upgraded my AC86U from 384.8_2 to 384.9.
This is the first time I see both Runner and Flow Cache enabled in HW acceleration. For all previous version I had not been able to make Runner enabled and stay in its state. Now it stays enabled for hours.
So far no unusual log (finger crossed). When a WiFi device connected, there is Assoc log entry, and when the WiFi device disconnected, there is Disassoc entry. Which is normal and useful. Security wise, can make use of this log to track for WiFi stealing too.
I think it only trouble you if your router is in public place and you are providing WiFi for your guests, then it will be too much entries in the log.
WiFi log is showing more information. IPv6 log is cleaner than before.
Thanks Merlin, Asus and all contributors.
