Scenario:

 

I updated the firmware in my EWS2910P controller to the latest release.

 

EWS2910P Firmware version: v1.05.42_c1.8.55

EWS350AP Firmware Version: v2.0.248_c1.8.14

 

I went in to change a setting in one specific Access Point and I get an
error about the mesh.wpa_key even though I am not using mesh as its
disabled.

 

Figure 1: Error message

 

How can I fix this issue so I can make changes in my AP configuration ?

 

Fix:

 

  1. Create an AP group and set the APs as members of the AP group.
