CM1200 slows down after 24-48 hours of uptime when using link aggregation
If I hook up my CM1200 to my router (an Asus RT-AX88U) in Link Aggregation mode, it seems to be consistenly slow down to only around 66-ish% of the full connection speed after somewhere between 24 an...
I'm having the same issue with my CM1200 on 1Gbps service (Charter/Spectrum) and LACP, after 8-10 hours the speeds drops to sub 100Mbps and more like 20-30Mbps. I'm running Pfsense and I have found if I 1. restart the modem it works for awhile or 2. just resetting the LACP interface will restore normal performance. I had a moto MB8600 before this and never had a problem with the LACP link on it. Is there a firmware fix in the works or already out? has it been pushed to ISP for testing? Looks like I might be going back to the MB8600 and returning the CM1200
Oh, great catch. Confirmed that if I bounce (shut / no shut) the physical interfaces, performance returns to normal. This should be easy to script to run every 12 hours or so. I'm going to give NETGEAR until near the end of my return period to try to resolve this one, otherwise I'll be swapping for a MB8600 myself.
I'm going to open a ticket as well and see what happens but i'm sure even if they fix it via a firmware update it will take 6 months before Spectrum pushes it out. I know Comast is a little faster with firmware updates. Nothing like a $200 modem not working out of the box correctly but its netgear so I should know better by now.
Well, NETGEAR support got back to me and said I had to call in, which I did, as this was not an issue they could resolve via email support. Phone support said there was no way to report this as a bug and insists that it's either a problem that will be resolved by RMA'ing the modem or had to be a problem with the switch, which conveniently was also a NETGEAR device. They said they had no method of reporting bugs to backline engineering, which is a bummer. I guess I have no choice but to return the unit and get a Motorola or Arris. I hate that, since I'm sure engineering could resolve this if I had a method of reporting it.
