T3200 and my own mesh wifi
 

Not tech savvy at all so looking for help. I have the T3200 modem installed into the garage and an Actiontec attached by coax cables on the main floor that has an ethernet cable attached to a Telus router (or extender?). I am wondering if it was possible to attach the ethernet cable to my own router (D-Link DIR-L1900 Mesh router) and connect all my devices wireless that way. What do I need to do so that I don't see both wifi signals from my T3200 modem and also the wifi coming out of my mesh?
