My C6833 14.1.B.1.532 keeps losing wifi connection. After short time the data stops transferring but phone still is connected to network. Sometimes it works after hitting "reload page" but often I have to turn off wifi on my xperia and than turn it on and connect to network again. And than it loses again and again. This is not a router/network failure because I tested this on several networks (home, work, publc) plus and at the sam time my C1905 works perfectly on the same network downloading same content (webpages, apps etc).
P.S. When I turn off wifi it turns off quite a long time, longer than when I turn it off when it's working fine, hope it might help
