KB/s is 1/8 of kb/s so your speeds are still not clear. Oh well--the difference with the magnetmix test is enough to show there is a throttle in place.

LW 4.10? 4.10.0 (12.22.2005)? There should be no problem with 4.10.9, or the current 4.12.3. There is a setting in both to throttle download speeds (in the tools->Options->Download section, but that is usually set by default to "unlimited." The 'Speed" option should be set to T1.

The other possibility is that the ISP's uses a throttle once a monthly limit is reached, and 15 KB/s sounds like a "modem speed" throttle. Home and Work accounts are often treated differently, but unless the ISP's person who reassured you is unaware of such a throttle, this seems unlikely.

So, the speed and download settings in LimeWire seems to be the most likely cause.

http://www.limewire.com/english/cont..._history.shtml shows a download limitation of 150 KB/s was in place before 4.11.1 (05.24.2006)
