In my computer, when I go to the local area connection properties, there is a tab called "configure". If I click on this I am presented with a screen showing various tabs like advanced etc. On clicking advanced, I happened to see some settings like "link speed/duples mode" and against that 10full, 10 half, 100 full, 100 half and auto modes are listed. what are these settings. Would changing any of these affect my connectivity speed?
