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 have a RAX80 with the CM1200. Same issue, it slows down to 30Mbps after sometime and have ot reboot. In addition when link aggregation is setup, xfinity speed tester reports lower speeds than when it is disabled.
Hello,
For those experiencing issues with WAN aggregation and is interested in helping us look into this further, please send me a message. Please provide me with your contact information such as name, email, phone, and contact time along with your serial number.
Thanks,
Christian
- I've got the RAX200 but not the CM1200 or I'd help out.
Good luck! Christian_RMine did the same, 20-25mbps until I ran speedcheck couple of times... These routers have great internals but without alof of firmware work their going to fail market wise. I'm contemplating taking this back for the GT-AX11000 right now...
I will PM you now.
Case #42302140 was created and escalated to engineering. I ran a multitude of tests. Once thing I can't figure out is how to acces the hidden debug logs on the CM1200. That might gleem some light on why speeds slow down after a few ours.
Another intresting thing to not is that without aggregation, speeds are 930Mbps. Immediately after setting up LACP, speeds drop to 650Mbps. Then as everyone notes, speeds can drop to as low as 20Mbsec after 24 hours.
- I actually get up to 1,200mbps (xfinity gigabit) with WAN aggregation immediately after reboot. This lasts for a few hours, until it drops to about 25 mbps. I get only 700mbps with a single WAN port . But, if repurposes then 2.5gb lan Port as a wan port, I get around 960mbps and it’s stable. And QoS works too (best option so far)
WAN LAG = 1,200mbps (but decays over 24 hours)
1gig Wan ≈ 700mbps (stable but underperforms)
2.5gig LAN configured as WAN = 960mbps (best option so far)- I don't have a rax200. I have a rax80. For me Wan aggregation means the wan port and LAn1 repurposed as wan2 is connected to the cm1200.
I do have lan 4 and 5 that can be aggregated, but for for lan traffic only.
I don't think I can replicate your setup with the Rax80
Fixed my WAN aggregation slowing down.... took this Netgear back to Best Buy, ordered Asus's AX6000 (RT-AX88U). WiFi6, 160mhz, more security than any router I've ever had including WPA3 & 6 weeks rolling with no hiccups....
Runs Merlin's firmware as well.
What cable modem do you have?
Hey Christian_R
Having the same issues that other people are having with WAN Aggregation with my new Rax120 Ax11 paried with CM1150v modem. After about 15 hours my agregate setup switch drops to 25MBS, normal speed is > 300MBS which my xfinity speed.
Setup I have two other routers that are bridges and about 50 ethernet ports, 5
unmanaged subset etc. I have many wireless devices. I have a large house >7300 sqft
and many computer and devices. Computer Science major with master degree. Many
years of experience debugging devices.
RAX120-100NAS S/N is 5ve3975yf04b4
CM1150V-100NAS S/N is 5fv1987aa05d3
All firm ware is up to date.

I don't know how to sen you my email and phone number, but I would like to help.

I have Orbi WiFi 6 router with two satellites, serial number
My problem is essentially the same as the rest in the thread. After enabling the modem and router for link aggregation, it works better than ever, but in less than 24 hours the download speeds crash to about 25 Mbps. The usual rate of over 350 Mbps is restored by just disconecting the cable from the LAN 1 port on the router, waiting 10 seconds, and replacing it! Then in 6-24 hours it happens again. My ISP is Xfinity.
Any ideas?

disable link aggregation for the time being?
Yes, that is what I had to do. But I would naturally prefer to use all the bells and whistles that are supposed to be part of this system. Am I right in assuming there is no fix but to wait for a firmware upgrade?
Same issue here with the RAX200 router and CM1150V modem. All my Ethernet cables are Cat 6a.
Speeds are 1100 to 1210 Mbps with port aggregation turned on. The next day, speeds drop to 18 to 23 Mbps.
The good news is the fix is as simple as unplugging and replugging one of the two Ethernet cables from either device. This leads me to believe it's a data syncing issue or possibly a queue of Ethernet collisions that have not been rectified. Removing and reconnecting an Ethernet cable resets the connection.
But it is annoying that I have to check my Internet speed and replug in my Ethernet cables each day. Hopefully this can be fixed soon.
I would love some help with this. I have WAN aggregation set up but every day i have to re boot.

Try opening a fresh conversation.
You have joined in on an existing conversation that may or may not have anything to do with your problems.
There is also a good chance that the official support team is busily monitoring new conversations and may miss your addition to this one.You could also try the section for your modem.
I am having the same problem. Is there a work around or a firmware fix?
Thanks
- Many times fastest is disconnect 1 wan cables from modem to router for 20 seconds or so and plug back in — I’ve been rebooting router when get slow down and that works very time.
I’ve asked support for at least an option to be added in firmware for daily reboot of RAX120.
My guess is that this will not get fixed and that new modems will start coming out with 2.5 and 5.0 gig single wan port vs WAN LAG — based upon all very latest routers from other brands already coming with multi-gig wan ports.
