I'm a novice here, trying to replace my old router.  I have Verizon FiOS, I tried plugging directly into the router and also from my old Verizon router into the AX21. The first three lights on the display are green, the internet is orange and the last two do not light up.  After set up AX21 comes up no internet.  What am I doing wrong?   Internet shows ok on the old router.  Help!
