Hows it working? Got your logs with that?
reason I ask is your snr is a boarderline and the upstream power seems a touch low.
But in some cases, that'll work fine so its more about how well its working and how the logs look.

It's working out better than before, but you are correct. The upload is not as high as expected. But it is much better than before. I get about 16 mbps upload and 86 mbps download. So I can live with that.
By the way, if I switch the modem to Arris SBG6580, I get 180 mbps download but only 5 mbps upload. I didn't realize modems made that much of a difference.
I was wondering if you had any idea why that is.

What speeds do you pay for?
both upload and download.
Who's your isp?

I paid for 75 mbps download and 25 mbps upload. My ISP is comcast.
While download is better than expected, upload is slightly lower.

I have no idea how the sbg8250 is getting 180mbps. sometimes ISP's overprovision but its usually only 10-20%. Not 200%+

Yeah, it's a mystery. I have searched everywhere on the web for an answer and no one seems to have an answer.

Makes me curious if they provisioned it wrong.
