Please follow the below steps in order to change the bandwidth limit of your handsets. Please be aware that setting the bandwidth limit too large or too low can have a negative effect on your network as device's will either be able to download a large amount of data causing congestion or will have a very limited speed slowing down any tasks which require transmitting over the network.

Please log into your Draytek router.

Go to Bandwidth Management > Bandwidth limit.

Set Default TX and Default RX to the limits you wish your devices to have.

Click OK.

Default TX sets the Upload speed limit, Default RX sets the Download speed limit. The Default settings affect every device on the network, you can limits for specific devices using the Specific Limitation menu. Please be aware that too high or low bandwidth settings can have a negative effect on your network.
