Hi chaps. My 3 month old hero ( 3 UK - 1.6 ) has just stopped detecting ANY wi-fi signals. I haven't rooted. I have removed the battery and removed then reinstalled the we-fi application. I toggle on/ off / on the wi-fi and the phone indicates this as being on. My next idea is to factory reset the phone and if that does not work to send it back to 3. Any ideas?
