Ocassionally my t randomly disconnects from the home WiFi network and when I open up the settings it reconnects. Anybody else experiencing that?

This happens to me sometime also, I believe it has to do with the location based Wi-Fi.
I'm using location based WiFi and haven't experienced it on 303 or 195 fw.
Could the 'wifi tx power' app help? I have no idea what the max power setting is for the T, or indeed if it is already set to max, but could it help improve connections?

I mainly get it after exiting YouTube or a full screen app.

I am finding this issue, 303 was really stable for me but since I upgrade via PC companion my device has become unstable with crashing camera and this issue as Wi-fi signal has been much weaker and disconnects regulary, I dont use location based Wi-fi so dont see it is that interfering. Any ideas?

[SOLVED] Data connection not working properly

Hello, I got an xperia z three weeks ago and it has always worked perfectly until yesterday: I'm experiencing strange mobile data connection issues. I can surf the web but if I disconnect and connect again, the connection may freeze: the H icon (or g or e..) appears and phone seems to transmit data as it shows an up arrow but the down arrow never appears and I can't surf the web. Toggling data and airplane mode may allow me to connect successfully but it's always pretty random..
I started thinking it was a software issue.. So i flashed The phone with the utility twice.. No success. Carrier issue? Nope: it's all ok and apn settings are ok as I can use them. Hardware issue? Perhaps as I found out that removing the SIM card and inserting it back in a certain way could make the difference (higher rate of successful connections).. So what do you think? Could be the SIM card (I got a new one in December though), the phone or something I did not consider? Sadly I can't test a different SIM now but as soon as I can find one, I will try. Thank you!
Re: [ISSUE] Data connection not working properly
Does it happen while your using the device or when it's sleeping you turn device back on? I also have sort the same issue but with WiFi..

Ok.. I found out the cause.. It is the carrier.. They said itwas all ok but many are reporting my same issues in my country.. So not fixed yet but I can stop flashing my phone twice a day.

Check advanced settings in Wi-Fi.there's a feature for turning off when screen is off might be there

I got the WiFi can work with another router which supports 802.11n
According to my device vendor
The WiFi chip is somewhat incompatible with old brand routers
