First thing is, you have your upload count way too high for being on a modem connection. The highest bandwidth a modem can handle is ~5KB/s. Network traffic consumes ~50% of your bandwidth (developers are working to fix that problem). So that means you have 2.5KB/s left for downloading and/or uploading. Of course you're going to be downloading and again your download speed will not be higher than 2KB/s. In your case you have 2.5KB/s...you're downloading a file and uploading 3. 2.5 divided by 3 is ~.83KB/s. Even on a 2MB file @ .83KB/s it'll take ~40 minutes. I'm also on a modem this is my setup.

my TTL = 10 (some people will say 7 is the max and hosts will drop you. Try a test get a stable connection on the network and search for well known @ 7 TTL count. With that same stable connection search for the samething @ 10 TTL count. The 10 TTL count will produces more results for the selected search.)

max TTL = 10

Keep up 2 network connections.

Max Uploads = 1

Uploads Per Person = 1

I set my Upload Speed from 3.5KB/s to "Unlimited"
