Unable to authenticate after some time on WAC120 (wrong password on WPA2 ) with firmware 2.1.5
I have two WAC120 devices. Since the fix on the security vulnerability with WPA2 (firmware 2.1.5) and the updates on our Android and iOS devices I can only use my access points during a few hours/day...
With the following combination the issue currently does not occur anymore:
- factory reset + installation of the initial firmware followed by the installation of the 2.0.5 one and afterwards of the latest 2.1.5.
- disabled band steering to 5GHz
- disabled the QoS WMM- latest iOS updates on all devices ( was one without a WPA2 fix triggering the issue.. ? )
Please note that I have no real proof that band steering or QoS is the problem. I will do some further tests over time..
Thanks for the great assistance by the Netgear community :smileyvery-happy:

PBrou Have you had a chance test by disabling band steering? Please share your feedback
Thanks

Hi,
I have been running one WAC120 device now during 3 days till it stopped working correctly:
- without the 5Ghz steering
- logging everything on a rsyslog server
What I observed is that the activity led (green - ethernet traffic) and the wifi led (green) were gradually more and more, increasingly active (without really having more traffic being "generated") till nearly constantly green when the device finally did not respond anymore with the following effects at the end:
- wrong password error on 5Ghz 11ac (gives me the impression of a timing error, or not getting enough processor time; kind of traffic storm not giving enough bandwidth for the device)
- nearly no traffic / slow on the 2.4Ghz 11ng
The last hours of the 3rd day I was using airplay for +/- 5 hours, not sure if this accelerated the kind-of-crash.
I have the impression - this is only an impression - that there is some kind of increasing traffic storm, broadcast storm, loop, or something that is gradually increasing the load on the device. And would the wrong password error not be the result of some timing error because of the huge load?
Anyway, in attach you can find the complete logging (quite big) of these 3 days.
I hope you are able to see something strange in the log files.
Meanwhile I will try to check the other traffic on my switch.
