i tried it real quick, and it doesnt work very good, the speed test is quite inaccurate, so the tweaks it will apply will not be correct. its not as good as using tmn to test, and cablenut to tweak.
Jammy your speeds are not that much lower then your advertised speed. do this clear your cache and then run this test http://www.testmy.net/tools/test/d_load.php?step1_timed=&step1_size=&step1_validation=&testall=&s=5983&st=st&ni=ni&ta=&top=&tt=1&nobar=
willemijns im not that impresed, tmn gives better results, and well i dont have to downloading anything here to do a speed test.
also, what kind of big bug did you have in your software?
i only see you getting 43kb/s on the upload, your download gets a good result. http://www.testmy.net/tools/database/s_engine.php?type=user_name&q=willemijns
it will eather be in the bios of the laptop, or some laptops have a program that will tell you the temps and allow you to control the fan speeds. look on your laptops manufactors website.
