I have done some testing and results are as follows

Iceweasel works very slowly after booting up but the stops entirely. I figured it is based on forefox so I checked the about:config networking section and compared it to my windows. (viitually the same file) so I eliminated that as a possibitity. then I installed firefox.
Firefox works the same as iceweasel. almost not at all..

I dont understand what the difference is between konqueror and firefox. Can someone tell me how theese two connect to the internet differently? understanding this may help me solve my problem.

Thanks for the help
