Re: CM1200 to Rax200 WAN aggregation slows down (requires reboot)

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.

The second bit of that is important.

 

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.

Re: CM1200 to Rax200 WAN aggregation slows down (requires reboot)

I noticed that Spectrum and Cox are using V1.02.01 firmware for the CM1200, whereas Xfinity has V1.02.02 deployed (see here). Are forum members with Spectrum, Cox, and Xfinity all experiencing the same decrease in download speeds when WAN Aggregation is enabled?

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.

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?

If you have a Cm1200, then this proves it's not a CM issue, it's a RAXxx router issue.

Went through ALL the newest, hottest wifi6 routers, both Asus's newest ones, Netgears....

Backed down to Asus RT-AX6000, got WPA3 with 160mghz band and have not had to reset, or T-O-U-C-H the damn thing since unboxing it & going through initial setup.  Setup was over a week & 1/2.  I'm no stranger to networking..... don't even go there...

Sherri1963,

and you can confirm you are set up for WAN aggregation?

Re: CM1200 to Rax200 WAN aggregation slows down (requires reboot)

This will be my last reply... I'll be changing my CM1200 as soon as possible.

Asus's AX6000 also includes 8 (E-I-G-H-T) LAN ports on the rear.  Use of No. #4 LAN port along with the designated WAN provides aggregation from the CM1200 with it's first 2 ports...

PROOF.......

C'mon, guy, let's have the idiocy you provided a little more, c'mon... where's the "language error" check?

I'm just providing this community with info that there is a router that provides the latest upgrades that functions as it says it should.....

TAKE IT OR LEAVE IT

Just like I'm l-e-a-v-i-n-g the Netgear community as well as it's products.

Good riddance,

🏄‍♀️

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.

Re: CM1200 to Rax200 WAN aggregation slows down (requires reboot)

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.

Re: CM1200 + Asus RT-AX88U I have WAN aggregation on mine & Q...

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.

Re: CM1200 + Asus RT-AX88U I have WAN aggregation on mine & Q...

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.

Re: CM1200 + Asus RT-AX88U I have WAN aggregation on mine & Q...

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).

Re: CM1200 + Asus RT-AX88U I have WAN aggregation on mine & Q...

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'm facing those issues now speed was great  its dropping badly both lan and WiFi are slow. Now resetting the rax120 without wan aggregation it goes back to higher speeds. And the pass I never had  any issues but I notice when this happens I'm pushin about 20mbps on a gigabyte plan

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.

Re: CM1200 to Rax200 WAN aggregation slows down (requires reboot)

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!!!
