Upload speeds with Comcast

[avoozl]

I'm on Comcast west, 8\768 package. I can get about 80kb/sec average on a fresh .torrent, with occasional "bursts" up to 200 kb/sec. Soon thereafter, the "bandwidth shaping" occurs, and I am back down to nothing.

This is something that started a few months ago in certain parts of the US. It has eventually moved across the country. There are still some users that aren't effected by the comcast shaping.

Thing is the shaping doesn't really effect when you are connected to other comcast leechers. Basically comcast only shapes the uploads when you are connected to people on other ISPs.

Anyway, there is no solution yet.

As mentioned the SSH link above might be one solution. Or you could find a private VPN and tunnel through that.

One day some genius will figure out how to fix it in the torrent app, but as of right now I don't think there is a solution.

If I establish a VPN through my router (dwrt linksys modified) can I figure a way to tunnel through that and increase upload speeds

Nikmash and avzool what modems do you use?? how do you push your upload beyond 100kbps on comcast?

I thought I'd post a graphical demonstration of my bandwidth shaping. As you can see, my maximum speed is about 180 kb/sec for brief periods of time. It is quite consistent how the shaping goes. I use a Motorola Surfboard SB5100.
It is interesting to note that if I set my maximum upload speed to 75 kb/sec, it will stay maxed out the entire time, (as long as there are adequate leechers available) but if I set it to unlimited, it goes in spurts, as above.

I'd be interested to see some graphical representations of other peoples' experience with comcast.

This is a screengrab from u-torrent with the timeframe set to 30 seconds. Any other timeframe does not show any discernable pattern.

The only other way I can think of to get by this is to make the client think it's still downloading. If I read the article right after it's finished thats when it starts to do that bs with killing the uploads. So if you can either slow down the download to .01 kb/s and keep the thing downloading the last say 5% or so you should still upload at your regular pace, or some how pause the download, but still have it classified as a download. Pause the incoming stream or something. Now the problem I see with this is the download slots. If the tracker still thinks your downloading the file your going to fill up your slots in no time at all.

I've tried that, but for some reason it didn't work. I slowed down a download to about 1k but the upload got killed at the same time.

As for embolism - I don't think you could create your own VPN (using comcast as the ISP), but if you knew someone or found a service that offered VPN through their a different ISP, it would work.

relakks.com offers VPN service as I mentioned. It does cost money and the speeds/connection time can be iffy.

As mentioned earlier in the thread, utorrent (and Azureus) developers know about what comcast is doing and are supposedly trying to figure away around this. I just think it may take sometime.

It seems like getting a cheap seedbox is going to be the way to go. If you just download straight from the seedbox with ftp to your computer and do everything from your seedbox you'll be covered. If you have to pay out money for it then might as well shell out a few more dollars for the extra speed.

Been looking around at seedboxes and I think I came up with a way to do it for $20 a month. If you just get a cheap VPS from http://www.fdcservers.net/Services/V...SVDSPlans#s101 and limit your download speed to something around normal speeds for a good internet connection you get rid of the problem. Now the theory on this is NOT to be using this as a normal seedbox to seed a tb a month. Rather use the 600gb they give you by throttling your bandwidth throughout the month. Then you just ftp the files to your computer and avoid comcast BS. I don't know much about this stuff so I'm looking for some feedback. What's everyones opinion?

If I have VPN access to my workplace, how do I go about this??? without the workplace knowing that I am doing this? usually when I VPN to workplace U torrent stops working - is there a way around this without then knowing I am using bandwidth?

You could try to "uncap" you modem but you may get banned if you do it wrong.(seach uncap cable modem on google) I read one guy uncapped and got 30\4 off comcast

Not that I know of. . .My guess is that your work has blocked torrent/p2p usage using their VPN.
