Have been using Xperia TX for about a year, and my routers and their settings remains the same.
However, starting from this week, my Xperia TX have WiFi disconnecting issues on both routers (a Netgear and a Belkin router).
I checked the WiFi settings menu when the problem occurs, it displays "Connecting..." and soon "Disconnected".
Switching WiFi off and turn it on again or enabling Flight mode and switch back would not help.
The only way to solve the problem is to restart my phone, however this is getting pretty annoying.
Have someone faced the same issue, too?
Is there any troubleshooting I can do?
