Re: [Speed] new "Performance Promo" is mostly unusable

You're on a low end speed package. If you've got several people using that connection isn't going to be slow. Your signal levels aren't terrible so it's not a service problem. You may want to simply move up a speed tier.

You're joking, right?

it's a 20 (burst) and regular 15Mb/sec connection. I was on a 6Mb/sec connection and it was fine. This is not.

Your response confuses me. If anything, it should be 2x what I was using.

Your shaperprobe results are not showing a 15meg connection.

Thank you. What DOES it show? It's a new tool to my eyes.

It shows 7down 1.5 up sustained. You're getting 18ish with PowerBoost.

Ah good catch. He's also got 6 down channels and 3 up, so it's HIGHLY unlikely that this is a node congestion issue. Plenty of errors in the logs too. Smells like something not great with the coax. Was this a self install?

No, it was a Comcast install.The log errors seems to indicate connectivity. But the connectivity it seems to reflect "T3 timeout". That seems like upstream to me.

The thing is, this connectivity would be a constant, would it not? Like I said in the post, early AM and the connection flies. Then it slowly starts to augur in. That, in my humble view, is misconfig or congestion,

There is almost 0 chance it's congestion with you having 6 downstream bonded channels and 3 upstream bonded channels.

T3 timeouts happen when the modem loses sync.

Your timeouts happened around or after noon, when you report speed issues.

That, and your totally misconfigured speed, indicate something is way off in your install. In other words, it's local to your install. Call them up or post in comcast direct and have them back out.

Oh, and verify you're provisioned right, your speed isn't right.

Thanks. That is really good to know.

I have the installer's phone number and I'l be calling him tomorrow AM to come back and sort this out.

Great feedback. I appreciate the confirmation. I will plagiarize the combined knowledge from this forum and speak with them first thing.

There are too many people using this for it to be as bad as it is for me. It MUST be a configuration issue, or multiple of same.

I have a truck scheduled to roll today between 2 and 4 PT.

The more I have investigated this (local users, neighbors, the COMCAST forum), the more likely it may be a result of an oversubscribed gateway.

I realize for most of the country that is a thing of the past - not here. And even with multiple bonded channels - if the gateway is under water the number of channels only makes it worse.

This is the same local COMCAST who charge the same for 12 HD channels on cable as they charge in Berkeley for 50+ HD channels. In other words, this is not a high end head end, and I have a very bad sense about the outcome.

I will happily post the opposite if they manage to make it work.

UPDATE: waiting for the COMCAST truck...

Like clockwork, shortly after noon PT, my link started cratering. It was behaving close to expected rates all morning, like normal.

Number of bonded channels be damned, this is congestion.

As of now, 1:10 PM, for example, I time out attempting to use the XFINITY speed test. I time out attempting to use speedtest.net. I am able to reach speakeasy's test, and manage a 0.69Mbps download and then IT times out trying to load the upload test.

The timing of the truck visit could not be better. I'm anticipating "you need to use our rental modem" and "let's reset the modem", ad nauseum.

Yes, I am getting cynical.

1 recommendation

I don't think congestion would start around this time. It would also tend to slowly build up, not be an immediate degradation of speeds.

Obviously something is occurring around that time each day, but it could just be someone who works the night shift waking up, turning on their old TV that has a noise/ingress issue or something that's hosing things.

It does build gradually. It starts and slowly goes down. It is slower in stages after 10 or 11 and it is hitting the peak now.

IT IS CONGESTION.

It could be, but I doubt it. Guess you'll find out once the tech gets there. At least they'll be there during the slow periods.

Agree. it'll get fixed, or it won't. I'll let you know.

Good luck! Hope they identify it at least and fix it if possible for you today
