Fast roaming doesn't work with DPPSK

dempie

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,
