Connection and compatibility checks should be handled in layers. Start with the app entry, then check cable or Bluetooth path, system permission, device screen, and local record. This keeps troubleshooting focused on environment and steps instead of jumping to a device conclusion.
Start with a stable app entry
Open Ledger Wallet from a known entry and make sure the app path is clear. If installation or download is part of the question, use Official App Download and Installation Guide before reviewing cables or permissions.
Separate cable and wireless checks
USB, Bluetooth, and mobile connection each have different variables. Do not switch all conditions at once. A wider FAQ path is available in Ledger Connection Troubleshooting when a quick overview is enough.
Read the device screen
The app can show connection status, but the Ledger device screen confirms the current state. If the screen does not match the app task, pause and reconnect from a clear state.
Write a local troubleshooting note
Record the entry, cable or Bluetooth path, system, permission state, and visible device screen. Do not include PIN or recovery phrase details. For setup boundaries, compare with What Is Ledger Initialization.
A good connection note changes one condition at a time: cable, port, permission, app restart, or device reconnect. That makes the result useful for the next check.
The goal is not to create a long technical report. It is to keep the environment, entry, device screen, and next action easy to review.
