For about 6 weeks now I've been having this problem. When I cold start my phone, WIFI is picked up (either at work or home) but then in 2-3 hours, the WIFI is no longer recognized or sometimes even turned off. I can't get it to be re-recognized or to turn back on unless I restart the entire phone. I have to do this 4-6 times a day. Any suggestions? I got this phone from Verizon in July 2012, so wasn't sure what to do. I'd prefer not to lose all my information, as my phone is my lifeline for business and personal use.
