CM1200 to Rax200 WAN aggregation slows down (requires reboot)
I have a CM1200 modem and RAX200 Router with WAN agreggation (2Gig). My internet speeds slow down to 25Mb after approx 24 hours. Rebooting the router fixes the issue for another 24 hours and then the...
I can confirm CM2000 firmware update to V2.02.05 at 1:20 AM CST (Minnesota). I have one of the warning messages asked about above in the logs. No messages since then.

It has been one year since Netgear responded to my escalated case on performance degradation that this problem would be fixed. I plan to test link aggregation later today, and I will report my results.
With the new firmware and LACP reconfigured on my CM1200 I am measuring between 1149 to 1201 Mb down and 41 Mb up over four hours. When I last tested with LACP 11 months ago I typically saw degradation within two hours. The CM1200 is connected to a Netgear XS716T switch. ISP service is Comcast/Xfinity Gigabit service.

24Hours into WAG enabled on my Asus ROG GT-AX11000 and my Netgear CM1200 and my speeds are as follows:

I factory reset my modem, disabling the WAG and speeds are now back up to the following. So from initial tests, it's better, but the issue isnt resolved entirely. I am forwarding my test results to my contact with comcast and my logs.

FYI: CM1200 firmware V2.02.05 appears to solve the link aggregation problem when using a RAX120 router, according to this thread (message #121).

Does any body know if LACP has been fixed on CM1150V with RAX120 as the router?
My version currently is v2.02.04 on CM1150v...
