Had an install about 2 months ago for Fidium, the techs (or at least mine) don't seem to know that they swapped to DHCP instead of PPPOE recently. I was told you could only use their equipment however after the initial setup I just gave them a ring and had them put my router MAC in and had no issue with it popping right on and grabbing IPs without issue. So relatively painless now in my experience!
