I'm new to Limewire and have read this thread (and some others) – it's great and has already helped me. I think I've put in all the numbers correctly but there seems to be a problem somewhere.
 
When I try the Bug report it says “Received incoming this session: false“ but I can download and there are also uploads. 
Downloads: 2–4 KB/s, sometimes 8–10 KB/s and I even noticed 40 KB/s for about two seconds, the numbers are jumping all over the place, going up and down all the time (usually staying below 5 KB/s) 
Uploads: 8–12 KB/s 
Shouldn't it be the other way around? 
I used 
www.pitstop.com. According to that site my download speed is 1400 kb/s (175 KB/s), upload speed is 400 kb/s (50 KB/s). 
What exactly is T1 and T3? I've never seen that anywhere and I haven't found an explanation.  
Mac OS X 10.4.1
Limewire 4.8.1
DSL 2.048  
Any help would be appreciated, thanks.
