This question already has an answer here:

I have two network interfaces which are a wireless and a mobile broadband. They have different networks or service provider. I plan to combine them for faster upload and download speeds. Is there any good way of doing this?

You might want to search for the term "bonding". This will allow you to use two connections in parallel. You will not be able to use the full bandwith of all connections with a single transfer, but if you have multiple transfers they can be routed through both connections for load balancing.

This seems like a pretty solid guide: http://www.cyberciti.biz/tips/debian-ubuntu-teaming-aggregating-multiple-network-connections.html

I am not sure this is possible with mobile broadband, but I may be incorrect. –  BiggJJ Jun 28 '13 at 10:07

I am not aware that this is possible. While uploading or downloading there is 1 connection made to the server the information is coming/going to. But is you were to use you mobile broadband, it would have to create a completely separate connection.

You could set it up as a "fallback" method if one was to fail, but using both at the same time for the same connection isn't possible.


EDIT: It may be possible to do this but via a Dual WAN Router such as: Vigor 2920.But this would be a question for Draytek.

You can load balancing over two interfaces in Ubuntu/Linux, but that isn't easy. –  Anders Jun 30 '13 at 8:17
