Internet link
I also need two internet connections simultaneously to ensure quick speeds.
You require a router that supports bonding for this setup. It combines two connections into one device to boost bandwidth. Keep in mind you'll lose some percentage of the overall speed, so don't assume it matches the sum of individual speeds.
It's possible to connect the link, but it usually won't boost your performance. When you save a file, it will use the fastest available connection. Bonding is mainly for distributing traffic and adding backup.
