Internet shutting down when disconnecting Shaw digital box

[wireless]

This is a strange situation and I'm hoping someone will have an idea what is going on. In December, Telus installed PureFibre to replace the old setup. Everything has worked perfectly since then, until this week when we decided to upgrade our tv to a newer model. We needed to change the digital box (from Shaw) and they sent us a new box.

So, we unplug the cable from the old box and suddenly our internet goes down completely. We connected the new digital box but couldn't get it to work because we need an IP address and we can't get an IP address without internet. We reconnected the old digital box to the cable and the internet came back on.

Both the Telus and Shaw boxes on the outside of our house are close together, but I don't see how they could be affecting each other? I'm going to have to contact Shaw and probably Telus, but I thought I would ask here just in case some wizard mind can come up with a possible cause. I have a feeling that I will get passed back and forth between Shaw and Telus before I can get a solution.

Thanks for reading and if you have any ideas at all, I would be so grateful to hear them.
