The point I was making is the GPL of some kind comes from Asus.
Without it this project would be dead or non-existent.
Just like I was getting a GPL for XT12 even though it is not posted on Asus support for XT12.
GPL is on the Asus page for the model.
Then you just include/exclude what you want in the firmware before compiling.
It is what even Eric first used back in 2012 for the RT-N66U.
Normally found on "Driver & Tools" then select "Others" for OS.
Does not change the fact it is a crap modem compared to just about any Broadcom based modem.
I have disassembled the coda56 as well as other modems and could not believe how cheap the components inside the coda56 are.
No wonder it has such a low price.
Coda56 has deteriorating fabric heat sink...
No I mean the same test with different modems. Depending on the modem I have seen some go down to C while others get A or B.
All on the same testing site, speed tier, PC and router with the only device difference being the modem.
All comes down to what is inside like CPU and other components...
No QoS, no bandwidth limiter
But I do own a top of the line cable modem (CM3000).
I have personally tested many cable modems and just a modem with better components inside can make a difference in bufferbloat.
Plus my ISP is now using LLD.
Last thing in the log is related to spdMerlin add-on.
Are you using automatic QoS?
If so set it manually as that has been known to cause crashes.
