-* __time_dl__: How long the download test should be in seconds
+* __time_dl__: How long the download test should be in seconds. The test will continue regardless of this limit if the speed is still 0.00 when the limit is reached.
     * Default: `15`
     * Recommended: `>=5`
-* __time_ul__: How long the upload test should be in seconds
+* __time_ul__: How long the upload test should be in seconds. The test will continue regardless of this limit if the speed is still 0.00 when the limit is reached.
     * Default: `15`

 * __count_ping__: How many pings to perform in the ping test
