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...
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.

vkdelta ... have asked AbhayB in another thread already:
Is there a common aggregation mode "standard" agreed between the makers of cable modems and routers? Asking because when we check Asus that they talk of dynamic 802.3ad/LACP for WAN port aggregation - while Netgear does not show any trace on the aggregation mode implemented - neither on the cable modems, nor on the routers supporting WAN aggregation. More than poor and non-professional documentation, poor KB entries, ...
CM1200 runs IEEE 802.3ad/LACP as well. (I believe this is the most common method on every other router as well)
xmit Hash policy is Layer3+4 (https://www.kernel.org/doc/Documentation/networking/bonding.txt)
vkdelta the point is that Netgear does _nowhere_ document that the modems and routers WAN aggregation does use 802.3d LACP. Instead, we get some point KB entries e.g. only for the AX12, which would be applicable to many more Nighthawk AX (RAX) and the basic Nighthawk routers, too. Quite a mess. Unfortunately it's not about what we would like to believe - I would have believed the WAC540 does 802.3ad LACP as it was even in the docs, but discovered the hard way that it's static LAG only (docs are supposed to be fixed in the meantime)..
