Both my CM1100/1200 don't have any LAG issues. LAG works with my R7960P with LAG enabled on the router. Only one problem seen with the 1200 is that some users are seeing speed slow downs when LAG is enabled on this model modem with there ISPs. NG is aware and working on it. I have my 1100 online currently. I'm not using LAG at the moment, however I have two separate orbi systems connected to each port on the modem geting different WAN IPs and speeds are mostly to spec. Seeing near 900Mpbs. Really is nice being able to have two separate networks running off 1 modem. :smileyvery-happy:

Comcast will activate a non-voice modem, you just have to be kind of sneaky about it. I was able to activate a SB8200 after activating a CM1150V but I believe that the trick is doing it through support chat so that they don't ask too many questions. On my triple play account, both the SB8200 and CM1150V show up, but I am only actually using the SB8200.

 

FURRYe38 - does the CM1100 not have the same issues as the CM1150V for LAG? And does the same apply to the CM1200?

The slowdown problen is the same problem on the CM1150v that the other models experience. The firmware is in Comcasts hands it's just a waiting game at this point when they push it out.

Hopefully CC will get the FW pushed for you. 

I have the same issue. CM1150V ->LACP->RAX80 WIFI router.

My Xfinity download speeds drop from about 1024mbps to 12-20mbps every 24hrs unless I reset one leg of the LACP pair. I've just been unplugging WAN1 and plugging it back in. As soon as the link resets my speeds are back up to 1G.

Hi,

I opened a chat support ticket with Xfinity tonight and the rep said she updated the firmware to v5.0.. The modem rebooted and still reports V2.02.04. She said it will update to the correct version in a couple of hours, so not sure if it happens during the maintenence widow around 4am or what. I'll report back tomorrow. I attached a screencap of the chat session.

I don't know what that agent was smoking, but  apparently there is no V5.0, another agent said the latest they had was V2.3.x... They weren't able to push that via the WAN, but scheduled a physical installation from a tech. We'll see how that turns out

Don't expect much from that visit either.

Indeed.. no luck with the tech either, the guy was totally cool, but alas, nothing he could do.

Thanks for the updates Wildbob.

You would think Netgear would make some effort to influence Comcast to push an update. Their modem is not delivering advertised capabilities.

ThePiston450 +1 I'm in the same boat as you and equally frustrated. Past return period.

Sounds silly, but I am thinking that maybe I get a programmable outlet timer that resets the modem nightly.

My quartely check in to see if anything has been updated here.

Really wishing I had gone with a different modem vendor :(

"Dude just disable agg and run 1 cable. I’m pulling 986/42 consistent. No restarting, no slow down, no problem." :smileywink:

We get that. And thats something you'll have to wait for NG and ISPs to get working. For now, use it with LAG disable or find something else that doe work for your needs. Any one tried the CM1100? 

Good luck.
