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...
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?

MikroTik RB4011 Ethernet 10-Port Gigabit Router (RB4011iGS+RM)

WAN LAG works without issue with above router -- Mikrotik are solid products, however designed (use and configuration) differently than the average home-based router.

I can't find in the tech specs or user manual the LAG method used is it 802.3d lacp or Netgear prop? Assume the two ends of the links are talking different protocols. Only way I could get this working reliably was to split links across two different on prem layer 2 switches then re aggregate them.
be great if tech support could clarify the protocol used then we could look up the tech specs of the modems and determine which will work or not. Other wise shooting in the dark
I have the latets firmware installed now for 2 days and stable without LAG for internet. I am now testing with LAG and will report back for router firmware version V1.0.2.88_1.0.50 (and the CM1200 modem still on V1.02.02).
Latest firmware on RAX120 1.0.1.122 didn't help, nor firmware from support -- with Comcast, cm1200 firware v1.02.02 and hardware v1.01.
Another router where WAN LAG does work is the TP Link Archer C5400X (WAN and Port 1), then use LAN2 and LAN3 for LAG to switch.Seems I cannot edit my post for an update, but the newest router firmware did not fix the issue. Internet slowed down 7.5 hours after I turned LAG back on.
- back to disabled LAG
