Interupted Connections...oddly


Recommended Posts

Recently, when I have been attempting to download a file over 1GB in size, my connection has been terminating. Not just in uTorrent, but my entire internet connection all together. I then have to reboot my computer and restart my modem. I since noticed that this only occurs when I leave my computer unattended for an extended period of time...say more than an hour and a half. I do not have my PC setup to hibernate, I have disabled Windows Firewall, turned off my screen saver and changed the power options on my monitor, basically turning them off.

Without fail, if I walk away from my PC for an hour and a half or more while performing a download, my entire internet connection shuts down. This only occurs when using uTorrent or BitComet. I have started downloads using FTP programs, or straight through the browser and they do not cause this interuption.

I'm lost now. Any help you can provide would be appreciated.

Even if doesn't get you closer to a solution, one problem I see is you're allowing way too many torrents at once and way too many upload slots at once for your upload speed.

9 torrents times 8 upload slots each is 72 total upload slots.

Splitting 40 KiloBYTES/sec upload speed 72 ways is really low even for dial-up speeds. BitTorrent *CANNOT* function reliably when you split your bandwidth so many ways.

The recommended settings for your connection are xx/384k in Speed Guide (CTRL+G), and even they allow more connections at once than needed for decent download speeds. (...Excessive amounts for less-than-perfect networking hardware and software.)

File size has very little effect on the number and quality of the peers and seeds you connect to.

If there's LOTS of peers+seeds and/or poisoners on the torrent, you may find your networking hardware and software...not as good as you thought!
