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...
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.
I switched back to my MB8600 last night and the issue is gone and honestly the MB8600 is just as fast if not better. So I'll be returning my CM1200 this weekend as well. Sad really because its a nice modem and like I said before even if/when they do fix the problem it would take close to a year if I was lucky before the update was pushed out by Spectrum. Better testing, quility control and reporting Netgear.
I ended up returning my CM1200 and replaced it with a Motorola MB8600 and everything is working great now. If you're looking to do LACP, I just can't recommend anyone purchase the CM1200 despite it being an advertised feature. It's obvious that this was untested and NETGEAR support is completely unwilling to be accountable for this. I'm tired of arguing about it... and to be honest, I'm not sure why I tried so hard anyhow to get someone to listen since I knew deep down that it would be a complete waste of time and nothing but blame shifting.
