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...
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?
All -
I have the same issue but with RAX120 AX12 connected to a CM1150V. I
have xfinity blast 300MBS. I have one own cable pedestal (long story), which is on my property and is linked with a RG61 copper cable. I live in a semi-rural area. I have many (5) 8 port subnets about >50 ethernet ports in house. I rewired my house in 2016 to use mostly cat7 which was best at that time. I have two bridge routers to cover my house with WiFi and add some more ethernet ports. Will be running a two cat8 a cables soon from bridge routers to RAX120.
1) I initially set up my new router cable modem using the 1 gb port. Was stable but speed was a little disappointing at 230Mbps. It was slow compared to what I use to get with my linksys router. I use to get 275Mbps with 6 year old linksys 8100, Xfinity up my speed to 300Mbps/DOCSIS 3.1. Hence I decided to try a netgear router/cable modem because I not excited about linksys mesh solutions.
2) Hooked up the WAN Aggregation two wire (Cat7) about two weeks ago to gain more speed. Speed improved to about 270Mbps but after 10 hours or so would drop to 25Mbps in my test. I reboot would always up the speed back to ~270mbs.
3) I just reconfigured my RAX120/CM1150v to use the 1 Gbps ports. Speed has been a little bit better ~370Mbps. I am currently not using the 5Gb ethernet port, I am thinking about to use it to hook one of my subnets too. They Leviton 10/100Mbps subnets.
4) All firmware are up to date.
Any help in getting the WAN Aggregate working?

A brand new firmware launched today for the RAX200. Doesn't even mention the WAN aggregation issue. But so far it has been giving me 1.2Gb download speeds for the past 4 hours. We'll see if it can survive the 24 hour typical time limit to degrade.
Just updated firmware myself a few minutes ago. Port Agg on and pulling 1.1Gbps.
Its roughtly 3:30 Central time here and I'll repost if I see a drop in speed.
For what it's worth I received a firmware upgrade for my Orbi RBR850 (wifi 6) router last night and upgraded. It is version V3.2.10.11. Port aggregation was enabled and it downloaded in excess of 350 mbps, but overnight dropped to the usual 24 mbps. By disabling the port aggregation the normal fast speeds from my Xfinity ISP were restored. I don't really need port aggregation, but I hate buying something that offers this modality knowing it is not working. In part it is a selling point of the two Netgear products and should be able to be enabled without this bug. I could accept it more if I could just get a good explantion for why it is happening, because I am always worrying that there is something else I could do on my end to make it work, and am just not doing it.
Just an update. 8 hours later and I've noticed the speed caps at 250Mbps instead of 1.1Gbps. No such luck on the firmware helping.
Apparently the problem is with the present modem firmware. There is a separate stream in the Netgear community that explains that an upgrade and fix is (probably) out there, but these upgrades are given to the ISPs (Comcast) to be pushed to your modem. For reasons not clear, that step hasn't happened.
Additonally, the concensus now is that if your download speed is less than 1Gbs, there is really no advantage to using WAN aggregation, so it may well be that because typical packages from Xfinity (comcast) are far short of that speed, they are holding back until they more routinely offer faster packages. Beats me.
- Yeah I have no issues at the time. Just curios to know if it helps With anything. Thanks though I definitely don’t want to cause any problems.
- There is only one advantage of you have less than 1Gb and that is diverse route failover. If one of the two cable fails, wan aggregation also takes care of failover to the other cable. Not very likely to happen, but it is nonetheless an advantage.
I also heard about the problem being on the modem side and that the isps will push it. Isps don't like pushing firmware because 1 they become responsible for things not working and 2, they don't like you using your own modem so they prefer it to be buggy. Throwing my hat in the ring with the same issue. Have the cm1200 and RAX200 with port aggregation turned on. See great speeds for a while, then drops to 25Mbps. Reboot router and I'm good again for another 24 hours or so. Replying here so I can hopefully get an update once fixed.
- As far as we can tell, the problem is with the CM1200 modem. Netgear just released new Router firmware for the RAX200 and it didn’t fix the Wan Aggregation issue. Other people with different routers have reported the same issue with the CM1200 modem. Netgear needs to update their modem firmware and strongly encourage ISP’s to do the same.

Netgear can do as many updates as it likes for cable modems, but it is down to the ISP to roll it out.
Users have no control of firmware on cable modems.
I've got Xfinity and just checked the firmware version on my cm1200 and it's V1.02.02 but I still have the slowness issue.
- I have Xfinity (Comcast) and the latest firmware. The modem still has speed degradation over a 24 hour period. I go from 1,200mbps to 24mbps in a day.
Confirming the same problem with the same setup. Also, it seems the QOS on the RAX200 is permanently disabled when multigig internet is enabled as I can't check the box to enable it.
- Thats by design. QoS doesn't apply for multigig so it's disabled.
CM1200 + Asus RT-AX88U
I have WAN aggregation on mine & QoS (adaptive) with fq_codel set for DOCSIS with upload/download limits set to keep buffer flow right is working great.
Sherri1963, thank you for your helpful comments, which suggest that the problem discussed here is with the Netgear router and not the CM1200 modem.
Just to confirm, were you previously using the RAX200 router? (Some forum members reporting the problem in this thread are using the RAX80 or RAX120.)
Finally, can you please share your observations on the performance you are obtaining with WAN aggregation enabled versus disabled, using your current configuration (CM1200 + Asus RT-AX88U)?
Hey Sherri1963
On the RAX120 and I believe the RAX200 routers the QoS is disabled by the firmware
automatically when you Set Port Aggregation to on (Enabled). You can't have it turned on.

One of many reasons I stepped away from Netgears newer routers...
Spent 40 minutes on phone getting to support yesterday on CM1200 critical errors, just 2 that are persistent to be hung up on. Never even given a call-back & that is the 1st thing they do is get a callback #....
Guess best bet is to locate a DOCSIS 3.1 alternative that can handle aggregation as well as 2nd IP and leave Negear completely.
Were having service issues with Xfinity right in the squared area my house sits in! Gigabit net is topping at 270- 400mbps (mb/s in router, have to convert on QoS manual). So on say 270 I set dwnld to 32 mb/s & Xfinity's 32mbps download always tops 40mbps, usually 42/43 so to keep buffer straight I set the upload to 4/4.7 which tranlsates right now to 130mbps+ consistenly on this notebook anywhere in the house I go. Faster if I'm outside but that's due to my AP.
When there isn't an issue & the modem has 976mbps, 137.5 MB/s dwnld has kept my notebooks (Intel Wireless AC 9260 160mhz) speed consitently at 600mbps. Have hit 700+ but only on 1st floor (main floor) of house. These are with WAN aggregation though... QoS doesn't have near the effect when aggregation isn't being used. Least not on my network!
I have to throw in that all my RJ45 cables are CAT7. Heavy duty, triple insulation that rates as waterproof, due to having a 100ft run to the outside AP, Amazon has a great seller that lists from 1ft, 3ft, to 200ft sections cheap & their all triple insulated, waterproof (can be buried) & this greatly increased reliabiility. Has been set it & leave it ever since (6 weeks & counting).
meant upload on the 32mbps..... sorry, it always tops out over 40mbps which is overflow.... where the fq_codel settings come in to play......

I only gave 300mbs service (Xfinity) but I am getting ~350mbs most of the time without Aggregate on. I ran cat 7 through out house about three years ago. I have still one cable to go. I decided to run cat8 outdoors it’s 81ft. I am hoping it’s long enough because the cable I am replacing was 100. Cat 8 doesn’t work well over 100ft. That’s what the specs say. I decided that wired solution was the way to go. I still have three routers with two being bridges because speed is much better closer to a router for some devices that need wireless.
I am waiting for a netgear solution to Aggregate. My speed has been stable so I am happy. Just a little disappointed because I was hoping to get faster speeds. I am not using the 5gig port either didysean to help. It is not the CM1200. I went through all the newer WiFI6 routers, Asus's & Netgears then switched to Asus RT-AX88U (AX6000) & WAN aggregation has been running on gigabit Xfinity 7 weeks now.... set it & forget it!!!
Three trips to BestBuy,
RAX200 RAX120
RAX80
The RAX120 was a mistake. They let me walk in one of the two Best Buy's here swapping the RAX200 & walk out with the RAX120, was in such a hurry didn't check. Then, went to the only other one in my area & tried the RAX80 just to see if this could be corrected (WAN aggregation) which it didn't. Speeds fell to what everyone else posted. My last return on the RAX80, ordered at register offline for the Asus RT-AX88U (AX6000 Asus brand) & it's over 7 weeks, set up & going strong.
I am currently looking for a replacement for the CM1200, since it has ranging issues when trying to renew it's ID.... but between Xfinity's lousy service tech's & life, it's going to be awhile....
Netgear self far behind the interphase the app the security I could've kept Comcast modem for $14 and $40Indeed it was a mistake I bought mines on-line Went to register it, Ha Netgear decided to end the remaining warranty. I normally go to Best Buy favorite store to go to elite member there so I left another net gear product Due to major security holes With the modem issue is still unresolved.. So that's another issue with netgear I brought the rax80 last year during the holidays I believe For a super super cheap price at Walmart with a extended warranty but it's sucked. I got this rax120 over An month ago. And bought the CM 1200 from Best Buy replace one of my modems I had a warranty with it so didn't really pay much out-of-pocket for the cm 1200 I got that because it was multi gig and I was upgrading my Internet service with Xfinity to get better speeds and want to use my own modem. I was extremely disappointed when I hook the RAX 120 up thanking since it's Netgear premium top product it would include Protection such as the amor bitdefender something besides wpa3 since other competitive companies offered this with their premium top-of-the-line product such Asus,TP-Link Netgear self far behind the interphase the app the security I could've kept Comcast modem for $14 and $4 extra bucks for xfi Advantage giving me unlimited data vs me paying an extra 30 bucks to use my equipment and have unlimited. The wan aggregation Was working but I've noticed it's dropping a lot and I was using a cat8.Now since I disable the feature must be so great but to have so much speed and no security I can't use my armored Protection that I already have on my other router with rax120 ,and rax80 I think I'm just going to sell this piece of crap and I'm going with Ubiquiti either the dream machine or dream machine pro most likely better service data products and great customer service and most importantly to me protection they offer intrusion protection and intrusion prevention which I should be able to push throughout one gigabyte speeds or higher with the advance security and enable on the dream machine pro and roughly 850 MB on the dream machine. I'm about ready to get rid of all my stuff with that switches ,routers,extenders,modems and ect on both sides business and the consumer side.. I would definitely say I'll look somewhere else they give you more value for the money you paid NETGEAR doesn't even know if Or when they were bringing protection to the ax products or the new Orbi.. and being nighthawk app it is so basic certain things you can't do from the app but you have to logon to the default address or routerlogin.com, or routerlogin.net Which is not very secure and netgear tell the Consumer in the support article related to the routers we speak of to use the nighthawk app You cannot branch in that mode you cannot go on to AP mode filter block none of that through the app only on the web interface. Netgear really need to get together with their engineers and redo this whole new lineup over and provide the needed protection and features if they insist we use the app.
