User fails authentication too many times in a row when joining WLAN

[wouter_beens]

Hello,

In the ZoneDirector I get multiple messages of clients who fails to authenticate too many times in a row when joining a WLAN. We configured multiple Open WLAN networks and it happens by all of them. In the Syslog Guide the action is to check the user credentials, but it's an open network with no encryption.

We use firmware version 9.10.0.0 build 218, but these messages where already their in firmware 9.8.1.0.101

Access-points type mostly T300 and ZF7762.

Has anybody experienced this before?

Do you know where it fails? There was an error reported (not on this forum) about clients not connecting, but the problem was that it failed at the DHCP stage not at the radio stage. So the auth/asoc phase went through, but when trying to get the IP it suddenly decided the connection was poor. It was an android Lollipop 5.1. Other clients worked fine.

Can you check if there is any DHCP discovery for that client before it fails?

And more 802.11ac AP features are enabled in 9.9.1 (soon), or 9.10 (now) if you can upgrade for further evaluation too. I'm sure tech support would like to know your findings.

Seems to be T300, I have a H500 close by and it connects no issue: Latest build .219, ZD1200
