Hi. I got my Xperia z1 only two days ago. I have been trying constantly to get my wifi work on it. It is so frutrating. Everytime I try connecting it says 'Authenticating Problems" I don't get it. Every other evice works fine with it. My ipad, my android, my sony +HP laptop, my ipod, my lumia. EVERYTHING. I have tried switching on/off my modem + my cell + using the forget option. Nothing seems to work. Please please please help ASAP. Also, how to I update to the latest firmware update. how do you do that?
