What's the reason for the vv5 network connection failure?

[DanielLee]

vv5 network connection failure reasons are as follows: Network module crash: During the upgrade phase, the device was in a shutdown state and did not upgrade at this time, causing the network module to crash indefinitely, similar to a phone crash, which led to the network disconnection. The solution is the same as with a phone, by powering off and restarting. Incorrect password: If the vehicle's built-in network cannot be connected, it may be due to an incorrect password or a system malfunction. It is necessary to inspect the network itself to find the cause of the fault and then carry out repairs based on the specific reason. After the repair, the vehicle's built-in network connection will be restored, and the network can be used normally once the issue is resolved.
