CM1200 slows down after 24-48 hours of uptime when using link aggregation
If I hook up my CM1200 to my router (an Asus RT-AX88U) in Link Aggregation mode, it seems to be consistenly slow down to only around 66-ish% of the full connection speed after somewhere between 24 an...
I have a NETGEAR CM1200 (firmware V1.02.02) modem, RAX200 (firmware V1.0.1.10_1.0.40) Router, Ubiquity US-XG-16 (firmware 4.0.69.10871) Managed Switch, Comcast Xfinity 1gbps in San Francisco, CA, and can confirm I also have this issue.
With LACP-IEEE 802.3ad enabled, I get between 980Mbps-1150Mbps for 12-18hrs, then speeds drop to 28Mbps-32Mbps.
I began hard rebooting my router when it first arrived, and I thought the problem was with Comcast until I got to this thread. I then disabled LACP, et voila, 850Mbps-960Mpbs without reboots every 12hrs.
Rather annoyed, as the one of the primary reasons for purchasing the CM1200 and the RAX200 was the touted agreggation, both for line saturation and redudancy. I would really appreciate a fix here NETGEAR.
I’m have the same issue. Bought the cm1200 and an ax8 router to leverage link aggregation to support future speed increases. Every 12-24hrs though speed drops to 25mbps. Really hoping there’s a fix for this soon.
If users don't want to wait for the ISP fix to come thru, users can try a CM1100. This model modem doesn't have this problem.
