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...
Did you read my post????? It is not the modem, it is Comcast. Read my post and do AS I did and it will fix your issues
Hey there, I did read your post, but I'm not sure that I really understand what you're on about. My cable modem frequencies are unchanged from when the issue is occurring versus when they are not. Furthermore, the signal to noise ratios (SNR) look amazing (around 42dB) and I'm showing no uncorrectable errors on any channel and little no correctable errors as well, shockingly. What were your statistics like prior to calling Comcast? I'm curious what statistic or metric I can point them to to indicate that there is a specific problem, since I'd love for it to be as easy as calling technical support and getting them to do something. With no indication that the issue is indeed on their side, it's hard to justify "raising hell", as much as we all like yelling at Comcast.
A metric that I do find interesting is that I see increased latency, upwards of 300ms RTT, to the cable modem's management IP itself (192.168.100.1) when this issue is occurring. This leads me to believe it's a runaway process of some kind on the device rather than an upstream issue.
