I just purchased the RAX200 and have configured it for link aggregation with the SB8200. When running properly I achieve download speeds of 1.2 Gigs. Every 24 hours or so the download speeds go to 3 or 4 Megs. If I unplug one of the ethernet cables the speed goes back to 950 Megs or so. I can then plug in the cable I had disconnected and get back to the 1.2 Gig speeds.
The RAX200 is showing that more than 4 Billion packets have been receiveed in 24 hours but very few packets have been transmitted.
The issue isn't just with the RAX200. its also with the arris sb8200. I have that some modem and it had issues with link aggregation as well. I was comparing the cm1100 to the sb8200 using both a netgear RAX200 and an arris AX11000 and the sb8200 wasn't at at stable with link aggregation on either device.

Interesting. I've read that the CM1200 uses a broadcom chipset as well? So perhaps that is the culprit? Have you found any any combination of router and modem that has stable Wan link aggregation?
