my xperia can not connect to any wifi. Previously, the problem persists, suddenly appeared. When connecting to wifi jumps alternately inscription: "lasts authentication" and "Getting IP address." Xperia was reset from the menu, by * # * # 7378423 # * # * and Sony PC Companion and the problem persists. Please do not write about WPS, because before the problem was not a xperia not even connected with urban spots
