CM2000 LED and R8000
As it's probably been fairly established that the R8000 has a firmware issue with handling data packets. i.e. not reaching speeds past 300mbps in my particular case. I am now trying to figure out why ...
FURRYe38 answered the 2.5g port versus the 1gig port.
in terms of the routers speed, you should be able to hit 800mbps when wired (won't hit that wireless).
1. what firmware version are you on?
2. have you used qos, access controls, traffic monitoring, or parental controls on your devcie? if so, factory reset it and reinstall it (not from a backup). during the install, make sure to leave those services disabled.
Yes thank you for answering the LED "issue." Rookie mistake, cannot believe I didn't even think about that. But now to the other issue:
1. Firmware 1.0.4.74
2. I had these disabled and did a factory reset last night. I left all of them disabled after the factory reset but it still was giving me speeds of 250-300mbps off LAN. I know it's not the cables as I got the speeds you would expect when I was directly connected to the CM2000.

How are you testing lan speed?
what pc/laptop and what site?
Using ipv4 or ipv6? (shouldn't matter but stranger things have happened)
Try downgrading the firmware 1 version. Then after its reset, only set it up with the basics. don't change anything.
Test its speeds at that point.
If it hits full speeds, then start changing things 1 at a time and see if anything impacts the speeds.
- I'm testing off my desktop computer (That's the one that has 2.5Gbps port if I did just the modem to desktop). I just use the speedtest.net by ookla in conjunction with Xfinitys speed test but mostly ookla.
I believe it's ipv4.
I'll have to try going down to the 1st firmware version and see. So far the only "fix" is manually setting the QoS to 1000/1000 which QoS should be off for the speeds I'm supposed to get.You don't have to go down to the 1st version. just 1 or 2 versions.
you get full speeds if qos is enabled and manually set to 1000mbps?
If so, leave it on. Its usually the reverse but if its giving you full speeds, it shouldn't be hampering anything then.
