Check the conditions and procedure for establishing a "Wi-Fi" connection, and perform the "Wi-Fi" connection procedure again.
As there may be wave interference, disconnect other "Wi-Fi" compatible devices or "Bluetooth" compatible devices before establishing a "Wi-Fi" connection.
A "Wi-Fi" connection can be established manually or automatically.
There are 2 ways to establish a manual "Wi-Fi" connection. Connecting by searching for a "Wi-Fi" access point, and connecting by entering an SSID and password.
Even though an automatic connection is enabled, a connection can be established only when a "Wi-Fi" access point with the same SSID and password that were used for a previous connection exists.

Bring a portable device to be used to establish a "Wi-Fi" connection near the in-vehicle device, and perform "Wi-Fi" connection again.
Considering the radio wave environment around the vehicle, move the vehicle and establish a "Wi-Fi" connection.

Move the vehicle to an access point where "Wi-Fi" connection can be established normally with other vehicles, and perform the "Wi-Fi" connection procedure again.
When the in-vehicle device is connected to an outside "Wi-Fi" access point, the "Wi-Fi" connection will be disconnected if leaving the radio wave service area.
This function is not designed to be used while driving. Use this function only when the vehicle is stopped.
