I recently bought an Xperia M last week and I love it. But I found a very unusual issues when I'm trying to connect to the Wi-Fi network. When I actually connect to the network, only push notifications work. When I'm working on the Internet or updating apps, it only works sometimes. I've already tried rebooting the system, wiping the settings, and factory resets...nothing has worked so far. Has anyone experienced this issue before? If so, did you get it to work? Thanks!
