Hello,
I've googled this using a variety of phrases but I can't seem to find anything and since I am very much illiterate in computer terminology it also makes it more difficult to know if what I am looking at is relevant or not.
Basically, I recently reformatted my computer. I updated all my drivers, but whenever my internet is under a heavy-ish load, like downloading multiple torrents, or even sometimes just one torrent at a decent speed (1mb/s), my internet stops working.
If I simply disable and then re-enable my adapter, it works fine again, but 5 minutes of heavy use shuts it off again. I use a wired connection plugged into my router via a CAT5 cable and I've made sure my drivers are up to date. I'm on Windows 7 64-bit. There are no bandwidth limitations from my ISP and normal internet use/playing games never shuts down the connection.
I tried using something called a TCPOptimizer from Speedguide.net but when I let it do it's own thing it didn't help at all; it actually made everything go much slower than default Windows settings.
I don't know what other information is needed if anyone even has an idea as to why this is.
Another issue that isn't as pressing is that since reformat, I have some sort of "built-in" delay in a game I play called Heroes of Newerth. Prior to the format I had about 50-100 ping tops on the servers I play on, but after I now never ever go below about 150 ping on the same servers. It feels like some sort of network setting or something, but again, I'm very ignorant so I have no idea.
Thanks for any help.

Sorry for being unable to answer the first questions but about HoN. It has been rather laggy lately, no Idea why and I tend to see loads of pauses because of this, which sucks. But, might there be any ports that might have changed? Doubt they'll do that at a format but might be

A friend of mine had a similar problem... He said it was something with his isp or router not allowing a certain number of connections at a time, so when he'd go on a website that had banners and stuff he'd lose his internet. Would explain why your's die when you torrent. I don't remember the solution :p

I suppose its possible but I didn't have the problem before formatting, suggesting it has something to do with some settings, somewhere, being changed.

I had the similar problem, replacing my router fixed it.

scrounge up an alternate network adapter and use that to see if the problem goes away.

Are you limiting your upload rate?
Are you limiting max number of connections?
Either of these could be affecting your network.
|
did this happen before you reinstalled or did you never try it back then? I have a similar issue: when i do anything that uses a lot of connections at once, after a while my router just craps out, sometimes to the point where i can only hard-reset it by pulling the plug. So, make sure it's actually a local issue on your computer and not on the router, before killing your system with random mods in hope to fix the problem.
What also might help is to just limit the amount of connections on your torrent a lot. Like set to max 3 torrents at once, and no more than 50 or maybe 100 connections per torrent.

Same thing happens when I used uTorrent. My internet becomes really slow and my browser stops working completely. I think you need to change your torrent settings.

Same here. It was a very old router which couldn't handle many concurrent connections and would disconnect all the time when under heavy load. No problems with a 35€ router from the nearest electronics store.

Well, it's not my router cause we got one of those experimental FCC gigabit routers (I don't even know if that's the right term, my roommate got it from them) that is really new and flashy.
I did that latency thing that Slothron linked me to but I don't see any big differences. For now I guess I will just stay away from doing other things if I have torrents running in case the internet shuts down.

It's probably your router. Next time it happens, restart your router to see what happens.
New and flashy routers are usually trash.
The default network settings in windows 7 are perfectly good 99% of the time.

pretty much this. i solved this same issue by getting a new(er) router

What modem do you have?
What router do you have?
If your ISP gave you a cable modem/router all-in-one, it's probably crap and the reason it becomes slow.
When performing NAT, your router has to keep track of every session.
In order to share the one external IP, sessions are differentiated using port number.
If two PC's on the network try and make a connection using the same port number, the router has to change the port number of at least one of them externally, and keep a record of which internal port number is mapped with which external port number, and which device on the internal network that session belongs to. It stores this information in the ARP table.
For incoming packets of that session, the router then changes the port number back to the original number the PC wants to use.
As far as the PC is concerned, the original port number really is the port number that's being used externally (even though that's not true, since the router changes it).
But if your router has a limited amount of RAM, a slow CPU, or a crap operating system, it quite often just can't handle having many NAT sessions.
The router I recommend is an Asus RT-N16, and put Tomato firmware on it.
It has 128MB RAM, 32MB ROM, and a 480MHz processor - which is far more than you'll see than in just about any other router, which allows it to easily handle a large number of connections.
Tomato firmware is essentially a linux OS for your router, which allows you to do much more with it than standard firmware, including run QOS
QOS is a feature that prioritizes traffic based on port number. You can specify which ports receive which priority, for example giving the port utorrent uses a low priority. So other traffic gets preference over utorrent traffic.
Using this router with my unlimited ADSL2+ connection, I can torrent as much as I like and it still doesn't affect my ability to play StarCraft II or use the internet connection to do anything else.

Something is limiting your connections or upload // download speed and once it breaches that it is disconnecting. It may be your router... I am not sure of any software that you may have that would automatically disconnect you from the internet.. but I am sure there might be some torrenting programs with that feature.

You really shouldn't use TCPoptimizer on windows 7 just so everyone knows or on vista, it handles things like that just fine as is
I'd set it up so that your router doesnt have to auto assign an address, i'd also change up adpater settings to discourage a heavy load it's likely improper drivers for the chip.

^^ again something like that is something you don't need to use or should use for windows vista and 7 i'm sure this is just a network card conflict with the router, set the ip on your computer to w.e your router uses like 192.168.0.67 then configure your network card which is kind of dependent on what there is.
|
He already has an IP and can connect to the internet, so manually assigning one won't do anything.
His problem is that too much torrent traffic causes it to be unusable.
|
the torrent traffic likely causes his router to drop him then reassign him usually a different ip address to the computer. Setting a preferred network ip on his computer can help prevent the drop while he puts his network card under strain. I'd also go to config his network card then limit his max IRQ per second to fit his max dl speed and make sure everything is set up right, like the use of full duplex etc. older network chips usually have shitty drivers for windows 7 that freak out at the littlest things so you have to baby them a bit.
|
Windows isn't going to just drop an IP as long as it's still plugged in. And DHCP will only assign a new IP if the adapter requests one.
The problem is the router itself handle that many connections. Unplugging it and plugging it back in would basically cause any open sessions to cease and the ARP table to clear.
The solution is to get a router that can handle that many sessions. Which means having enough RAM, a fast enough processor, and a stable OS.
That's why I recommend an Asus RT-N16 + Tomato
A TP-Link WR1043ND or Netgear WNDR3700 are good too. Though being Atheros based, they won't run Tomato (which is my favourite of the linux-based firmwares).
They'll run DD-WRT, which is still good, though I've heard QOS on DD-WRT isn't as good as on Tomato.

Thought I'd give my 2 cents here. As has been said before, it's looking like the router can only handle so many connections at a time. You said that you didn't have any problems before reformatting, so maybe when you torrented before the format you had limited the upload/download rate and max connections in your torrent client? I'd toy around with that. You should still be able to hit high download rates using the router assuming that the people seeding are using high upload rates (if you decide to limit max connections). Other then that you could try a different network card, but I don't think that's the problem here. Or buy a new router outright if you don't want to limit max connections. Good luck whatever you choose :D
