Hi I bought my Galaxy S2 SIM FREE several months ago. Running Froyo and then Gingerbread. No problems. A week ago I updated to ICS via the phone itself (not using Kies). Again no problems. Yesterday I decided to wipe my phone and reinstall a few things just for good measure. Again no obvious problems. However, this morning I am finding that the Wifi will not turn on. When I drop down the menu at the top and hit the Wifi button, it turns dark green instead of bright green and will not turn on. After a while it goes grey again but simply will not turn on. If I hard reset the phone and begin again from scratch, once I get to the screen where I enter my Google account details, it displays "turning Wifi on" and just locks up for ages doing nothing. Please please may I have some help and ideas? Thank you.
