Transmission disconnects me from internet

Asked by james bolen

Hello all. Ive been having this problem since i started running Ubuntu 9.10 desktop on my netbook. I am fairly new to ubuntu but so far have found the os relatively easy to use. I upgraded my os from windows 7 starter to 9.10 desktop about 5 days ago. I have been trying to run torrents through transmission since then but have thus far had absolutely no luck.

I will be connected to the internet, start running the program, then for some reason my dl rates will drop rapidly and i will just disconnect. It's seemingly random occurance in regards to time as well, as the program will sometime work for 5 minutes, other times 30 minutes, but the end result is always the same: i will invariably be disconnected from WiFi connections without any decent amount of data transfer have taken place.

I have tried using several other torrent programs and they all act the same way as well. For the brief time i used windows 7 starter i had no problems in regards to torrent progs, i had decent transfer rates and could stay connected all day.

Am i doing something wrong?

I don't know of any reason why BitTorrent should work better on one OS than another.

The most common reason for network p2p network problems are (1) not reserving some upload bandwidth for your non-p2p applications and (2) having too many peer connections, which can overload your router. So, two things to try are to set your BitTorrent program's upload speed limit to about 85% of your ISP's upload speed limit, and also to lower the maximum number of peers your BitTorrent program allows.

Can you help with this problem?
