Toshiba satellite l750 internet not working

[seeami]

this laptop has been awful and unreliable, suffering many crashes and moments where i have to go through the services and self troubleshoot what one is causing the problem. the main problem now is that the internet doesnt work.
i have tried in safe mode with networking, and the same problem. my wireless adapter shows up as the atheros ar9002wb-1ng

when i log in, i see an icon of a monitor with an excalamation mark next to it, which says no network acces when i click it. i'm sending this from my ipod, so its not a problem with my connection

when i tried to reinstall the wlan driver from the toshiba site (win 7 64 bit) it comes up with a message when i run the setup, saying that i cant copy a file to a destination. i tried changing the setup location and running as admin, neither worked.

please help me, as this happened so suddenly- it was fine last night and i woke up this morning and it didnt work.
