Hi,
we notice a strage issue for a while now when WiFi clients are connected to a 802.1X RADIUS WiFi that contains APX320 and APX530 APs that are managed in Sophos Central. Occasionally it happens, when they move in the office and roam between the two models, that they lose network connectivity and the new AP is not authenticating the roamed client against the RADIUS Server. At the RADIUS server we see no authentication - neither failed or success - happening.
We have the feeling that is is only related to the APX530 - The clients have no connection, when they are connected to APX530 with 5GHz. Central still shows an IP Address for the client device, but the device actually has no IP on it's network adapter. When we reboot the APX, it usually works again. Fast roaming is enabled.
The users help themselves by turning their WiFi adapter of and on when they face the issue. It will not workaround immediately, they usually need some attempts until it may fix the issue. When it finally works, they are still connected to the APX530 as it is the nearest AP then. On the RADIUS we will then also see that authentication happened and was successful.
WiFi AP have Central firmware v2.3.4-5
There are only a few clients connected. No real load for the machines.
I'd like to know if there are known issues with that or if you have a hot idea how to debug on this.
