# Troubleshooting UP.Review

## Diagnostics

You can view critical data, such as video speed or audio speed, for your media files, via the Diagnostics view.

### Viewing Ping Speed

You can test your network ping speed at any time in the Speed Test pane. To view your ping speed, do the following:

1. With a media file open in the media player, open the *Network and Transcoding Diagnostics* view.
2. View the ping speed, in milliseconds, on the *Ping* meter.\
   The *Ping* meter displays the speed of the portion of the media compared with your ping speed. A ping time higher than the crossbar indicates your network speed might be too low for streaming video.

### Testing Download Speed

You can test your network download speed at any time in the Speed Test pane. To test your download speed, do the following:

1. In the Diagnostics view, click the **Show Speed** button.
2. Select **Show Speed Test**.
3. Click the downward-pointing arrow.\
   UP.Review displays a drop-down menu of simulations for several combinations of file speed and resolution.
4. Select the simulation desired.
5. Click **Start File Download**.\
   UP.Review runs the simulation and displays the download speed in Mbps.
