# Arq Help

## Restricting Network Usage

Arq can restrict the rate at which it uploads data. To set the restriction, open "Preferences" (from the "Arq" menu) and select the "Network" tab.

### Automatic Transfer Rate

If you select this option, Arq uploads data at maximum speed unless you are using the network interactively. For example, if you're browsing a web site or watching a video, Arq detects this activity and slows its upload rate.

### Fixed Transfer Rate

If you select this option, Arq will not exceed the kilobytes/second you specify when uploading data to S3.

### Use Specific Wireless Networks

If you select this option, when Arq is using Wifi it will pause itself unless the Wifi network name is checked in the "Select Networks" window.
