sony xperia u wifi problem

[captain_peperho]

Hi everyone,
I recentely upgraded my sony xperia u to android 4, and after three days the wifi began to not work properly. The icon keeps on showing that the wifi is connected, even if the network is not accessible, and I have to reboot the telephone in order to switch the wifi off/look for hotspots. Has anyone experienced the same problem? Any idea on how to fix it?

Thanks

Hi,

I've just found a solution to put off the wifi without restart the phone. Just download and install WiFi OnOff.

It does not solve the problem but it brings a little comfort.

If you have any other solution since last message please tell me.

Thank you.
