The Groove 52ac can be set up by the Dealer or Distributor with a default configuration that does not include a default IP address. If you go to System->Reset Configuration and check mark "Do not Backup" then click the "Reset Configuration" button you will have an opportunity to when you first login to see a discription of the default configuration as well as the actual script. Your Groove is probably set as an AP/bridge, CPE/bridge or with no default configuration.
The code below is the default configuration from a Groove 52ac that is set as a CPE/router which uses 192.168.88/1/24 as its access IP address. If you copy this, put it in a text editor and save it as a .rsc file. This script can be installed on your Groove by moving the script to the Groove flash/ folder then going to System->Reset Configuration and check marking "No default configuration" and "Do not backup" then in the "Run after reset" box select "flash/your-file-name.rsc" and finally clicking "Reset Configuration". You will lose this configuration the next time you do a reset. You should not use the Quick Set page to make changes to the configuration. You should use the menu buttons down the left side of Winbox to make changes.
The configuration can be made to be the Default Configuration after a reset by installing it using Netinstall.
