Bittorrent + Mobile broadband problem, it just doesn't make any sense!

[Black March]

I have this almost ridicilous problem about bittorrent and my mobile broadband router, the Huawei E589.

In short, I've limited the amount of bandwidth it has access too. I've limited the amount of simultaneous connections. I've limited upload speed. And I don't even have to be downloading much, but oftentimes my connection simply goes bananas. And it's obviously bittorrent related.

Scenario:
Testing an upload / download speed of 28 mbps down and 24 mbps up.
Downloading in bittorrent at 45 kbps, uploading at a rate of 1kbps. Only one download, so a maximum of 50 simultanious connections. Not uploading or downloading any other files, all have either been stopped or removed.

I'm fully capable of streaming full HD content from youtube/netflix while doing this. As long as I started doing it before things went south.

But I cannot load simple webpages, like anandtech forums or online newspapers. Without trying at least 10+ times. Regardless of whether or not I happen to be streaming video.

Closing down bittorrent fixes the problem almost instantly.

Honestly hope someone here has any idea of what could be happening, cause I sure don't. My bittorrent client is uTorrent. And it doesn't always happen, but it happens quite frequently still.

You need to configure the router for port forwarding the client.

I'm just curious here, why do you think that would help? Not quite sure I get how port forwarding is relevant to this problem?

I run v7.2.1 for the simple reason that all the later versions I've tested constantly had problems with settings and configurations not seeming to stay set. That's my own personal experience and you didn't say what version you currently run, so I can't comment on the version you have.

What I can comment on is that the default random port access setting allows BitTorrent to "hunt" for whatever port/s it needs, at any given moment in order to maintain a connection, and considering that the capabilities of your Huawei E589 may be limited is the reason I think it would be prudent to forward a single port for the BitTorrent client.

It's a very simple procedure to perform, and if it doesn't solve the problem then I would suspect that there's a problem with the actual version of BitTorrent you're running and/or how you have it configured. Port forwarding in this case will help you to diagnose whether you have a hardware or software problem.

firewall?

firewall?

Disabled it because of the problems, probably should enable it though cause it didn't seem to help at all. Disabled both on PC and router

Are you loading an IP Filter with Bittorrent, if not it could be the problem

I've seen this problem before on small routers with weak processing power.

Your max of 50 simultaneous connections is only the number of peers per torrent and not the global max connections which is usually 400-500 or more. Running torrents on underpowered routers typically causes hiccups like hangs, slow response, overheating.

So reduce your global max connections to 100-200 and see if it helps. Port forwarding might reduce the strain but its probably minimal compared to reducing the workload of the router by cutting down on the number of connections. Your torrents will take time to get up to speed as a result of reducing the global connections.
