Torrent problems

Right now I switched from time warner to Uverse but it came with a 2wire 3800HGV-B Residential Gateway which is a modem and router built into one. The problem is if I am using bit torrent, the connection will come to a crawl and will even drop during slow download/upload speeds. I am pretty sure it is because the built in router sucks and I didn't have problems with time warner and a linksys but I do not have the linksys at the moment to test on.

My question is if I use a different router in this guide , will it do anything since it still has to pass through the 2wire gateway?

Re: Torrent problems

I found using a better, 2nd router, makes an IMPROVEMENT, though its still not perfect, or how it should be by any means. The problem is, the 2Wire, still proxies everything through itself. If you set it up correctly, you can take some load off of the 2wire, but, when going full throttle, and you know, actually use your connection, it will still buckle :-\ Again though, with a decent second router, you will see a decent improvement, especially if you setup a QoS traffic shaping system.

I agree, DMZ a second router and then input the normal port forwarding settings in the second one, it's how I do it.

Re: Torrent problems

I have no problems maxing out my bandwidth with an ancient Linksys WRT54GS v4 (same as WRT54GL) running DD-WRT firmware.

If I limit the download speed to e.g. 1.0MB/sec then the rest of my internet is fine.

Keep in mind if you saturate your connection with a torrent, it will slow down e.g. web surfing.

Re: Torrent problems

I'm using the 2wire for torrenting.

I'd suggest tweaking your settings.

I hit about 1.9MB/sec peak. Make sure your ports are properly forwarded, or you have uPnP enabled. Set max connections to 400 global, 100 per torrent, 4 upload slots. Upload speed is at your disgression. I suggest anywhere from 50-80, depending on your connection and how u use it.

Re: Torrent problems

Hm, I have a feeling I know what they are talking about, even limited torrent bandwidth, the 2Wire doesn't seem to like to many tcp connections before it has issues. Have you ever checked your latency while doing torrents? It is typically not to good, even if your not 'maxing' your connection

Re: Torrent problems

I'm connected directly to the 2wire and using utorrent ,port forwarded correctly. I got onto that computer and opened up IE, to find it wouldn't load any webpage. I wasn't downloading, and my upload was limited to about 50 kb/s. Once I stopped all torrent traffic the web browsing was fine. I figured that was weird since 50 kb/s isn't THAT much. BTW, I could still browse the web with little speed lose on a different computer connected wirelessly before I stopped the torrents.

I can try the second router idea, but should I really not be able to browse at all just on that computer?

I'm FTTP with 6/1 service.

Re: Torrent problems

You can try limited your upload a tad more, and limit your torrent connections, thats about all you can do. I have found the same issue though, that the RG provided by ATT just seems to buckle when using torrents. Not sure the exact cause, though I have tried every way to "tweak" and "limit" torrent settings with no effect. Only thing that helped for me was a second router that I knew was able to handle torrents and while this didn't fully correct the problem, it did make a huge difference. I imagine from taking a decent size load off of the 2Wire.

Re: Torrent problems

QoS Shaping second router can help as well.

Re: Torrent problems

If that really is the case then my rating of the RG was just downgraded from "annoying and clunky user-friendly crap" to "utter crap"

Using an external router (a 4-5 year old Linksys) unless I approach approx. 90% of my upstream or downstream capacity I see no effects at all on web browsing.

Re: Torrent problems

I tried the second router setup without success. I've got Azureus running on a random-ish 5 digit port number and I've set up port forwarding on my firewall, first on the 2Wire box and then later on my Airport Extreme when I was doing the second router setup (2Wire was set to allow Airport Extreme DMZ access). In both cases, network speed without Azureus was good, about 5.71 Mb/s speed test on an Elite 6Mb/s connection. However, start downloading in Azureus and everything on the network slows down to a crawl. P2P traffic never goes above 125 kb/s download and network ping times are in the 900 ms range.

After multiple physical setups and changes to software configurations, I can conclude one thing for sure. BitTorrent traffic is the switch. Doesn't matter how I set up the torrent application (limiting bandwidth, paring down simultaneous downloads, turning on encryption) or which torrent client I use, the mere action of starting a torrent download slows my connection to something like 200 kb/s overall.

I was a Comcast subscriber for 10 years and this feels an awful like what was called throttling or packet shaping from a few years ago. There were some lawsuits files against Comcast and they eventually had to drop this practice. Before I switched from Comcast to U-verse I was getting P2P download speeds in the 1.5 Mb/s on a regular basis which was great when it worked. Now I'm kind of regretting the switch.

If anybody else is having these problems, please reply in the thread.
