Are you at the same location as the AP? Verify firstly that the AP has power. Then verify the status of the LED on the AP what is it doing? If the AP does not have have Internet connectivity, it will broadcast a survival SSID.
If a Meraki Access Point does not have a configuration from the Meraki Cloud Controller it will instead broadcast a default SSID of "Meraki-Scanning." The AP takes an address of 10.128.128.128, the SSID runs DHCP, and it will try to assign any clients that associate with it an address. This is merely to provide a connection between a client and the AP to allow for local configuration.
You can associate to this SSID and see the local status page which will tell you where the device failing.
