Instant On - Wireless

Dear Experts, 

One of my customer was using AP11D at home, the box is lost and serial number sticker is also not on the AP anymore. They mistakenly deleted the AP from mobile App. Now when we reset and try to find the AP through BT, it is not getting detected. Previously also at the time of fresh installation it didnt work via BT and we had to enter the serial number manually.

Is there any way to discover the AP without serial number? or anyway to get the serial number of AP now?

plug the AP11d into your network and then run a network scanner to find the IP address of it and then web browse to it. Should give you a status screen and from there can determine what mode is in, waiting for on-boarding etc
