Fast roaming doesn't work with DPPSK

Hi,

I have a network of several Zyxel access points WAX510D with a Zyxel switch XGS1930-52HP. All devices are running latest firmware, that means version V6.25(ABTF.2) is installed on WAX510D, V4.70(ABHV.2) | 05/21/2021 on the XGS1930-52HP. Switch and access points are connected to Nebula Cloud, organization type is Professional Pack.
The network is divided into different VLANs. Regarding wireless clients it is implemented by using different preshared keys (Zyxel DPPSK) on a single SSID.

Problem is:
If a wireless client roams from one access point to another it leaves the DPPSK associated vlan and gets shifted to the default vlan of the SSID.
It happens when fast roaming is enabled on SSID. Disabling 802.11r the client stays on DPPSK vlan.

Is it a bug in firmware V6.25(ABTF.2)?

Thanks.

Best Regards,
dempie

    Hi @dempie

     

    After looking into your settings, we setup a same environment and the case can be reproduced.

    We’re investigating the root cause and will fix it asap.

    Before solution released, pleased disable 11r as a workaround.

    Sorry for causing inconvenience and thanks for concerning the issue.

     

    Regards,

    Hi @dempie

     

    Sorry for the late reply, the fix of DPPSK vlan problem with fast roaming not yet been in time to be released in the version V6.30P0C0.

    https://community.zyxel.com/en/discussion/12462

     

    But good news is the solution has been found, we can help you upgrade to date firmware once you provide the schedule for us to apply.

    Please enable the Zyxel support at Help > Support request > Invite Zyxel support as administrator, and provide the Org and Site name.

    It’s fine if you want to wait the official release included the solution.

    Feel free to let us know. Thank you!
