Question: Sometimes after I shut off Wi-Fi using the button inside the notification bar drop-down, I can't turn it back on with that button. Hitting the button does nothing, it's not even highlighted. When I go into `Settings -> Wireless and network -> Wi-Fi settings` the status under "Wi-Fi" shows Error. If I click "Wi-Fi" to turn it on from here, it usually turns on without any problems. Occassionally I have to reboot to fix it.

Is there a fix I can use to make the TouchWiz Wi-Fi button work the same as enabling/disabling the Wi-Fi in Settings? Or, ideally, is there some way I can prevent the Wi-Fi from getting into an error state when I turn it off and back on?

I have a Galaxy S Vibrant running 2.2, but this has been reported on other Samsung phones as well ([example](https://android.stackexchange.com/questions/12233/wifi-error-when-turning-on-closed)).

Answer: 
I've had this happen to me 1 time. I don't think there's anything you can do about it except use the settings. Once you change it in settings, does it work again for you? I did the same in settings, but don't know if I rebooted after the fact.

This could also be something in Nero v3 that is causing it.
I had all sorts of weird problems like this when using TouchWiz on my Droid Charge. No problems after installing LauncherPro. Perhaps its an odd bug in the TouchWiz code.
