Main Causes and Solutions for Shinkansen Free Wi-Fi Connection Issues

High User Traffic and Network Congestion

【Cause】

During peak hours, the number of simultaneous connections increases, which can slow down the connection speed or make it difficult to establish a new connection.

【Solution】

• Wait a while and try to reconnect.
• Time your connection (e.g., wait a few minutes after departing from the first station).
• Move to a less crowded car and try to connect.

Not a Wi-Fi Enabled Car

【Cause】

Not all train cars are equipped with Wi-Fi, and older cars may not have the necessary facilities.

【Solution】
