Using a Bonded Network to Stream

Livestream Studio has the ability to stream via a bonded connection, allowing you to stream over multiple Ethernet, Wi-Fi or 4G/LTE network connections, increasing your bandwidth while also allowing you to create network redundancy. 

Important: Bonding is only available when streaming to Livestream. If choosing multiple providers, be aware that other providers will use only the network you selected when configuring each provider's stream settings. 

While Windows should recognize and automatically install any necessary drivers for USB modems, the drivers can also be manually downloaded from the modem vendor's site. Ensure that all networks can access the Internet.

In order to successfully stream with a bonded connection, ports UDP 2088 and TCP/IP 80 need to be open in addition to standard Firewall ports.

As a best practice, it's recommended that USB devices are spread across your PC's various USB ports and hubs. This avoids taxing each USB hub and ensures that each modem's connection is used.


In Livestream Studio, navigate to the Stream tab and login to your Livestream account.

Select your event, then click Advanced Settings.

Check Use Bonding, then click Done.

At the top-right corner of the Stream module is a gearwheel. Select this to configure default settings for your stream, including your default network. Here you will see a Bonding column with each corresponding network and a small dropdown menu with the following options:

  • Use: Networks with this option selected will combine together and distribute the stream.
  • Standby - use only when needed: This network will not be used unless all other active networks lose connection. For example, if you have a 4G USB modem plugged in with data caps, you may want to consider saving that as your backup connection to avoid data overage charges.
  • Off: Will not be used at any point during your broadcast regardless of the status of other network connections.

When you go live, your network dashboard will show information for each network, such as the bitrates each active one is distributing and if one disconnects.

Your standby networks will not stream unless a problem occurs with all of your selected primary networks (i.e. those with Use selected).

    With a premium streaming plan, does my network quality limit the number of viewers?
    What is the minimun uplink speed for streaming 1080p video?

    Hi Fernando, Since nobody else has responded I'll give it a shot.

    1) You only send one feed to the server. The network takes care of sending it to everyone else. There is no limit on an a premium plan.

    2) In the studio presets there's no way to send a single 1080p stream to livestream. For 720p you have three HD options - all include lower bitrates for viewers that can't keep up. HD+ does 720p at 4mbps which along with the additional HIGH etc streams comes out around 6.6mpbs. You need a robust 10mbps up to stream comfortably.

    Internet Society, are there any settings you can tweak in Livestream to achieve a higher upstream rate? My upload is 20Mbps and other applications can hit up to 15mpbs, but with livestream I am lucky if I get 2mpbs. That is streaming 720p

    Meaning if I stream it onto Facebook, this feature is disabled?
    Thank you.
