SOLVED:  I had the same problem when I upgraded to CM2000.  The issue is with your old router, it's too slow.  I was running an ASUS RT-AC68U and getting speeds of 400- 500 Mbps.  Problem solved by upgrading to a Nighthawk series router, CAX30 in my case.  You might also solve it with an updated router from another OEM, but be sure they support gigabit Internet in their specs.  Seems to be a common problem with users of the CM2000.
