I have ICS on my Samsung S2 I9100 phone. I was able to turn on WiFi until about today afternoon. Now, from recently though, whenever I turn on WiFi, it does not turn on WiFi at all: the device shows that it is re-trying to turn WiFi on, but the status remains "off". Hence, I am unable to see a list asvailable WiFi networks.
I have not installed any new app or updated any existing apps for this issue to suddenly occur. Any idea why this is happening, and how I can solve this issue?
