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:

Please find my answers below:
a. Are there any other access points nearby within the area where the WAC120 is deployed?
There is approx. 7 meters between the different access points ( 2 WAC120's and one in my xDSL modem/router).
b. How is the WAC120 deployed? Is it mounted on the ceiling or in a side-wall? Is it on top of a shelf?
It is currently standing on the ground (one on the ground floor and one on the floor at the attic)
c. How high is the WAC120 from the floor?
0 cm, it's on the floor in both cases.
d. Kindly try to unsecure both 2.4GHz and 5GHz wireless networks configured on the WAC120. Are you able to go online wirelessly just fine on any wireless device like laptop/s or android mobile phone/s if the 2.4GHz and 5GHz wireless networks are unsecured?
When running as open network is seemed fine.
e. Have you tried changing the wireless channel on the 2.4GHz and 5GHz wireless networks?
Currently they are both / all in auto-channel mode but normally I optimize them manually.
f. Did you perform a factory reset on the WAC120 after you have upgraded the firmware to v2.1.5? It is recommended to reset the access point back to factory default settings after doing a firmware upgrade then reconfigure it from scratch in order to start clean using the latest firmware version.
Because of the issue I did a full, clean install on them:
- factory reset
- installation of the initial firmware
- installation of the 2.0.5 one
- installation of the 2.1.5
Currently I have changed a number of settings:
- I de-activated the band steering to 5GHz because I saw a lot of log entries with the same time-stamp (not sure it is/was problematic)
- I disabled the QoS WMM (not sure that my mobile devices are tagging the traffic correctly so not sure anyway if it is useful)
The access points are now running again stable for 2 days. As soon as it fails again I will configure it as open network as you suggest (d).
Note that I use a lot fixed IP addresses for my mobile devices ( static IP-Mac address linking in my xDSL modem/router) and they are attached via a fixed UTP cable to my central switch.
Thanks for your swift reaction! I will keep you posted.
Please share your AP configuration once you see the issue.
Thanks

PBrouThe problem is appearing again!
In attach details from my logging.Switching to OPEN instead of WPA2 did not help, only rebooting (from admin UI) helped.
It would be great to have some assistance on the interpretation of the log file.The issue is only appearing on the 5GHZ 11AC, not on the 2.4GHZ.
