Dear All

I'd suffered from this problem, Wifi can not turn ON/OFF for a long time too.
I agree that Smack it sometime can solve the problem but, after trial and error for a few months, I'd found the my solution is 100% work (at least for me).

My Solution
When you want to Turn ON Wifi and the antenna icon doesn't appear, Do the following Step.
1. Eject the SD Card but still leave it in the slot. So normally there will be around 1 cm of SD card over the PDA.
2. Softly Press the SD Card from the back of PDA. I expect the inner of SD card to press some component on PCB (which I don't know what is it).
3. Wait for a while, the icon will be appear.
4. You can fully insert the SD Card into the slot.



I guess ,when I press the SD card from the back, the SD Card inside will push some component on the board.

Hope that you can use my solution.
