Friggen Comcast and their throttling...

I'm annoyed with how Comcast sends me these dumb e-mails telling me that my machine is infected. I'll go to their "Am I botted?" page, and it'll usually tell me that there's some IRC worm. Comcast gets that info based upon traffic usage. Comcast, you dummies, I'm not infected by some IRC thinger, I use IRC. To note, the page says that I'm clean right now. 😛

No I haven't been downloading torrents or pr0n, all I did was download the games from the Square Enix bundle on HumbleBundle. I get this crap all the time...every month I'm allowed to download one or two games before I get throttled to hell. Now my internet is near useless until they decide to stop screwing me. Last time I let the speed test run it measured a .03 Mbps. Woo...

I would have to change my provider or if no other option move...
 
Hmmm, that's a coincidence. I have Comcast and it's been working fine (I've only ever had a problem once and that was when they were throttling Netflix several months back) except for this evening. I can hardly stream YouTube and even trying to navigate ATOT it's worse than a snail's pace.

Maybe weather is affecting part of their network or lines or something?
 
Info on the what seems to be the most common Arris model:

In theory you should be able to pull 20Mb using 1 64QAM DL carrier - however, it's likely that Comcast provisions resources based on maximum spectral efficiency, so if you're not running at 256QAM you wouldn't get full throughput. They probably also time multiplex across available channels, so if you're not running all 4 channels, DL will suffer.

Also I think the marketing guys overstate the acceptable ranges on signal quality - at least my Motorola does. I had issues with terrible DL performance for a while, even though all the line statistics were inside the specified ranges.

However, pulling a splitter out of the run to the modem completely fixed the issue. RF measurements improved by the predicted amount for one splitter (2way splitter is ~3dB power loss) and now are a good 6 dB above the specified minimum.

I would recommend connecting the modem without the splitter and see how performance goes. Also check to make sure you see appropriate power improvement from removing the splitter, a bad splitter will generally cause a >4dB drop.

Yea I've been having outages at least once per week with this latest cold snap. My theory is the internet pipes froze but I can't prove it.


And Drako: Yes 10.0.0.1 is real. I logged in last night to double check and messed with some stuff. I couldn't find any diagnostic logs though.
 
Yeah, he probably has one of those new All In One XFinity wireless/modem/phone gateways. I had the misfortune of using one until I switched to Frontier UVerse. I could never get a VPN connection working on it, and I'm still not sure why.

The interface on that thing is really oversimplified, and they make it a pain to dig down into the diagnostic info like signal strength.

Yea...mine is a voice and internet gateway, so it has to do a lot of jobs. I also learned its able to to MOCA which I did not know.

Uverse was way worse. When I had to setup port forwarding for my security cam, it was a pain in the dick.

I've got the same gateway, and it's been pretty rock solid for over 2 years now. I did have Comcast put it in bridge mode, though.

Yea, that's real. The Comcast Arris Gateways I've worked with are all set to run that range. 10.0.0.1 /24

not only that, but all 3 that I've setup in the last year were set to give the entire range as DHCP. So that got changed to .2-.100 and gave printers .101 and up.
 
I have Comcast for internet, no video services. For TV/Movies I do everything by streaming, Amazon Prime, Netflix, Hulu, Youtube, etc. I am well over their "cap" amounts every month and I have never been throttled.

You probably, should call them. They aren't intentionally throttling you.
