turns out nothing major was wrong with my car. te racket was full of dirt said the mechanic. the fluid wasn't able to get through, and air pockets were forming. so he flushed all the fluid out to clean the racket and refilled the fluid. i used to have to hunch over my steering wheel and use all my strength and weight to force the wheel to turn. now it turns so smooth it's unbelieavble.
and dad got Stupid (my laptop) to connect with the roter finally. he just had to redo some adress thingy or something. he said that Stupid would be faster with the new roter but he is still the same. oh well, i didn't really expect this old thing to speed up. but as long as he doesn't slow down we'll be okay.
