If you are trying to switch to wired connection, pleas make sure:
- The physical connection between Lightning device and router is stable. You may take another ethernet cable and try again.
If you are trying to switch to a wireless connection, please make sure:
- You have entered the right password of the network you are trying to join.

Other issues that may cause the problem:

- Lightning device will try to 'ping' the gateway of your network and make sure the connection is a success, please make sure the gateway you have entered is correct and the 'ping' answer function has been enabled on your network gateway.
