Been having this problem for a while now; Seems like every so often, my wifi will stop functioning and no matter how much refreshing and fiddling i do, the only successful solution seems to be to restart the phone. Once i do that, everything is fine until this issue happens again of course.

I've tried a couple wifi-fixer apps to no avail except for one that did the trick for a couple months i'd say. but recently it stopped saving the day.

I'm a loss when it comes to what kind of information can make my problem easier to solve so feel free to ask. i'll put my phone info here in the meantime:

SGH-T959
2.1-update1
T959UVJI6
2.6.29
