Xperia z2 problem

Hello
After having to format my Xperia Z2, I had a lot of problem
wi fi in the force that has become very low
surtou and I have not found WALKMAN
please a solution or a link to an update

I suggest that you try to repair the phone software using PC Companion..

Before the repair of your device, you can back up your information first. See this topic for more information on how to.
How to backup?

If the question must remain, I think that this must be examined and fixed to a repair center. For more information on how to submit your phone for repair and where, contact your local support team.

  • Authentication of Wifi Compact Xperia Z3 problem

    I just bought the z3 compact xperia and will have problems connecting to wifi. It connects iinitally, but then it says "authentication problem. The password is correct, and I don't have this problem with another camera. I need a solution that does not involve having to access the router. Someone knows how to fix this?

    Thank you.

    You have access to a PC or a Mac? I would recommend that you try to repair the software of your phone using PC Companion or Bridge for Mac, but please note that this will reset your phone and deletion of your data. When you start the phone and set up again, make sure to turn off the option to backup & restore with Google when you add your account because it contains WiFi settings and to avoid problems under restoration.

    If the issue should stay I recommend that you contact a local support team or a location of the helpdesk to have your phone checked.

  • WiFi Xperia Z3 problems (home)

    Hello

    I searched the forum for people with similar problems but could not find my exact problem, so I made a new post.

    Problem:

    My phone has trouble with my wifi at home. It is connected and it works well at first but after a while, after a few hours of sleemode, the internet is really, really slow and fails to load movies Youtube, Facebook or other applications. He can always upload sites but extremely slow. After a reboot the wifi is very fast again and no problems until I had it put in sleepmode for awhile.

    Parameters:

    I have the endurance mode but disabled the option that turns wifi when the phone is idle. I also activated the queue of the background and disabled the 'eco wifi' function from the settings menu.

    Wrap-up

    After a few hours of sleep, wifi mode is not usable until I restart. I don't want to restart my phone often for my wifi working.

    Everyone knows about this problem? Does anyone know a solution?

    PS. the router works fine with other devices and use b/g/n, WPA2 (no weird characters).

    Thank you once again Rickard for the quick response. It turns out that the problem is related to "Optimizing Wifi" (think that's what it is called in English) in the Wifi settings. Since I turned it off, I was not able to reproduce the problem.

    It should save the battery, but it isn't really save when you are unable to use wifi more thanks again for the reply!

    Hi @Rosebud64

    OK, let´s ttry what follows, but first, make a backup of the device information. Perform a repair of the system usingbridge for MACor PC Companion . The process will erase all internal memory. You might need to charge your device for about 1 to 2 hours until the device has so at least 80% battery. Turn off your phone and unplug the PC (Hold to increase the volume and power for 10 seconds) start PC Companion and select the area of support then update my phone/Tablet and then blue repair my phone/Tablet and follow on screen instructions - when prompted, connect your phone turned off always hold volume or back button - this should begin the process of repair or reformatting. If you use Windows 8/8.1 or a 64-bit operating system and then adjust the settings for PC Companion and run in compatibility mode and has chosen Windows 7 or XP. Keep us updated please, I m available for questions.
