if youre on a *nix machine run "cal 9 1752" in terminal. it will forcefully calibrate your wifi to work better. the 9 is the highest level of force and 1752 is the process id for wireless controllers.
also if you're not on a *nix machine then you should just off yourself anyway. im on a windows pc but i got ubuntu on another partition because i know not having that back up would make me suicidal
