i am trying to register 7925g with cucm 9 but 7925g is not even getting the IP. i am using the following link for defining wpa2 preshare security. i am configuring the SSID name same as defined in Meraki dashboard and chosen the security mode as AKM, but i am confused about username and password (do i have to enter ssid and key in username and password field) and also where to enter wpa2 key. can somebody share the detailed settings configured on 7925g
