Re: [Speed] Comcast Business Class Speed Upgraded in California

said by pflog:

Should we be rebooting our modems and testing again?

If you are not getting the new speeds, a reboot would force the modem to take the new config. The configs haven't changed since last week.

Thank you.

Nope, not working for me. Still see very erratic speeds.

Can you post ShaperProbe results also?

Sure, but the average overall speed is fine. The speeds just bounce constantly between like 5MB/s (way above subscribed rate) and then down below 2MB/s (TCP stack reacting to packet loss).

It's clearly not being shaped properly after PB.

Shaperprobe results:

Connected to server 83.212.4.36.

Estimating capacity:
Upstream: 7275 Kbps.
Downstream: 34500 Kbps.

Upstream: No shaper detected.
Median received rate: 7275 Kbps.

Downstream: Burst size: 20790-20986 KB; Shaping rate: 28448 Kbps.

Here's the IO graph for the first, second and third 10 seconds. You can see when power boost ends, the speeds going nuts.

Got ya. Is this causing issues for something you are doing on this connection?

Thank you.

Yes, it affects latency sensitive applications (e.g. working remotely over VPN to a VNC session).

But more to the point - it's just plain broken. If this is "ok" and Comcast has no plans to fix it, we need to know ASAP, because, at least for me, I would look into either downgrading my speeds or seeking alternatives to the service (without an ETF).
