wtf???

another 1 to be shit about - my stupid fuckin' laptop. i don't know la why suddenly the wifi will turn off by itself. it takes a while for it to be connected. if there's no net, my mozilla will get stuck. if i play my mp4 files, the player will get stuck. dammit la!!! i have to wait for a month at least to send it to my uncle to fix the prob. anyone knows any solution to this?
