Select the Download button to download a single. The download rate is by default set to 'Don't limit', the upload rate to 'Limit automatically'. Type or paste the file or folders Dropbox URL into the browsers address field, and then press Enter. Dropbox lists the settings for the download and upload rate in the menu. You do that with a right-click on the Dropbox icon in the system tray and the selection of Preferences from the context menu.

If you are experiencing download rates in the 5KB/sec to 20KB/s range and have a Internet connection capable of handling a multiple of that, then you may want to try the following configuration change to see if it changes your Dropbox download speed. Dropbox is by default set to unlimited download rates.

If it is an important file you may want to tweak your Dropbox settings to see if it changes the download speed to the better. Demos are usually not time-limited (like Trial software) but the functionality is limited. And availing it isn’t the hardest of tasks. It may terminate the public link once the bandwidth threshold is surpassed. That's not an issue if you do not need access to the files that are downloaded fast as you can just keep Dropbox running as a background process until the data is transferred. A simple workaround is installing a smal program: sudo apt install sni-qt. Sometimes, or maybe even all the time, when you synchronize or download files from your Dropbox online storage you may notice that file transfer rates are lower than they should be.
