*5G WiFi networks are not supported. 2.4GHz WiFi connections only (if it's not labelled as 5G it will almost certainly be a 2.4GHz WiFi network).
WiFi settings can only be changed when the device is turned on and connected to the Console.
With your Walker turned on, open the ELEMENTICE™ Console and click on "Devices" tab at the top banner of the Console, then select the relevant Walker.
You are now on the Device Page and can access the Device Settings section at the bottom of the Page. You can choose Yes to enable wifi or No to disable wifi.
Once wifi is enabled, you will be able to enter the name of the WiFi network you want the Walker to connect to and the password to join the network.
*If the WiFi network you want to use has captive portal restrictions turned on, you will need to contact the network owner to arrange special access.
