Devastator

I recently upgraded to WM 6.1 L11 and I can't get my wifi turned on. I press the button, the power option comes up, I press the button again, and before I can even tap okay the screen goes away and the WiFi still doesn't turn on. I've even tried going into the wireless settings and pressing the WLAN's "TURN ON" button and that does nothing.

Don't press the button again, just tap on Wifi or BT or both and they will turn on or off.

Edit; Reading your post again, if you can't turn it on from the Dell Wlan Utility then you have a problem.
Perhaps just a soft reset will fix it or you may need to reflash the ROM.
I would check on Lenny's site for any discussion about your problem.

The Wireless Power Configuration in L11 has a bunch of settings you can change.
If you set it to just Wifi, two taps of the button will turn Wifi on and off, if you have it for Wifi and BT then it takes multiple taps to get what you want. The Ok button is pretty meaningless. If you press the button once and both the Wifi and BT appear in the little screen, you can tap one or the other or both and just wait and it will turn on or off as required. If none of these work then you need to check with Lenny.
