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've got 1Gbps down and ~20-30Mbps up. I can get largely the same speeds with a single cable, but the slowdown is still kind of concerning on the off chance I can eventually get faster speeds.
this is interesting as I have not heard of it..
Is this reproducible in your environment?
which ISP are you with?
Does the problem go away if you reboot the router?
How Long does it take the issue to appear?
It's pretty consitently reproducible to me. I had to turn off link aggregation so I wouldn't have to reboot the modem every other day or so.
My ISP is RCN.
I'm fairly certain that rebooting the router did not help, only rebooting the modem fixed it.
I'm not 100% sure how long it takes to manifest, since it would frequently start happening while I was asleep or at work, but it is definitely greater than 24 hours, and less than 48 hours.
and you just let the modem run as-is with regular internet use.. Nothing special.. Is that correct?..
will check it on our side.
- I may have brought up the Connection Status and Event Log pages once or twice, but that was mostly after it had slown down to see if I could find any obvious problems (I couldn't). Definitely at most I may have looked at the a few of the pages in the modem's browser UI without changing any settings.
Also while I'm thinking about it, I think I checked the Link Aggregation setting while it was slow once, and it reported Link Aggregation as disabled even though it was seemingly active. That may be related.
