   NG

Result: 

NG 

PERFORM WI-FI SETTING AGAIN 

Result: 

OK 

See step  2

1. Check the conditions and procedure for establishing a "Wi-Fi" connection, and perform the "Wi-Fi" connection procedure again.

   HINT: 

   • 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.

1. Check the device to be connected via "Wi-Fi".

   HINT: 

   Considering the radio wave environment around the vehicle, move the vehicle and establish a "Wi-Fi" connection.

   Result

   Result	Proceed to
   The in-vehicle device is trying to connect to the "Wi-Fi" access point of a portable device such as a mobile "Wi-Fi" router, tethering device, etc.	A
   The in-vehicle device is trying to connect to a "Wi-Fi" access point other than a portable device.	B

Result: 

B 

See step  5

Result: 

A 

See step  4

1. Bring a portable device to be used to establish a "Wi-Fi" connection near the in-vehicle device, and perform "Wi-Fi" connection again.

   HINT: 

   • Considering the radio wave environment around the vehicle, move the vehicle and establish a "Wi-Fi" connection.
   • Depending on the type of the portable device, customer operation such as internet sharing, tethering settings, etc., may be required whenever establishing a "Wi-Fi" connection.

   Result

   Result	Proceed to

1. 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.

   HINT: 

   • 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.

1. Bring a well-known portable device such as a mobile "Wi-Fi" router, tethering device, etc., near the in-vehicle device, and perform the "Wi-Fi" connection procedure again.

   HINT: 

   • Considering the radio wave environment around the vehicle, move the vehicle and establish a "Wi-Fi" connection.
   • Depending on the type of the portable device, customer operation such as internet sharing, tethering settings, etc., may be required whenever establishing a "Wi-Fi" connection.

   Result

   Result	Proceed to
   "Wi-Fi" connection can be established.	A
   "Wi-Fi" connection cannot be established.	B

Result: 

A 

END (ACCESS POINT WAS TEMPORARY ABNORMAL) 

Result: 

B 

See step  7

1. Check the wave interference while a "Wi-Fi" connection is established.

   HINT: 

   • Check the "W-Fi Connection History" around the time that the malfunction occurred.
   • Using the GTS, proceed to the appropriate link in accordance with the result of "Wi-Fi Connection History".

     Refer to UTILITY [10/2022 - ]
