My xperia disconnects from home wifi

Hi, I have the Xperia Z3, Until recently, my phone was fine. About 3 weeks ago it started disconnecting from my home wifi, this is extremely annoying. It does it when it feels like. Mostly when ive been idle for a bit, but does occur at other times too, in the middle of a written conversation it disconnects.
Things ive tried:
Resetting Router, moving it.
Resetting apps on phone to default.
Forgetting the Wifi connection and re connecting it.
Its doing my head in now need it sorted.
Any suggestions / fixes?

Hi Moreton,
Discussion Welcome to the community! Since you're new please be sure that you have checked out our Discussion guidelines
Are you by chance using any Anti virus or Task manager or even battery saving apps? if so they may be causing the drop in the Wifi connection. I suggest looking through and removing any if you do have them.
let us know how you get on.

  • Z10 keeps disconnecting from home wifi network

    I just switched from a Samsung Galaxy to a BlackBerry Z10 a couple of days ago and I am having trouble with my home wifi. The Galaxy never had issues with it and stayed on constantly but the Z10 connects for a few minutes and then disconnects again and won't re-connect unless I reboot the router. I made sure I had the latest firmware on the router and updated the Z10 software as well. Apparently there is some setting on my wifi that was ok for the Galaxy but not ok for the Z10 and I hope someone can help me figure it out. Nothing else is using the wifi and the signal strength is very good.
    What happens:
    The phone connects successfully to the wifi. I open the browser and go through a few pages and then suddenly a page won't load at all. Sometimes the phone says it is still connected to the wifi and sometimes it sends me a message saying that the network has limited access to some websites. Sometimes it will instead switch to 4G. It doesn't only happen when I use the browser. Sometimes I am not using anything on it at all but just look at it and see it has switched to 4G.
    I go into the settings and I see that it says my wifi network is disabled. I enable it again and confirm all the settings are fine and try to connect. Sometimes it goes through three attempts and then gives up. Sometimes it only tries once and gives me a message that it is unable to authenticate against the network and that I should verify network security settings and try again. No matter how many times I try, it does not connect until I log in to my router and reboot that. Then it connects immediately without my having to do anything.
    So I am pretty sure this means a problem with my router settings.
    I am using WPA/WPA2 - Personal security and confirmed that setting and the password on the Z10 are correct.
    On the Z10, "Auto Obtain IP" is on.
    I always have trouble with network stuff and it means little to me so, if anyone knows what is going on, please don't give me technical jargon! If you need more info, I will provide.
    Thanks! I don't want to have to take it back but if it won't work for me, I might have to get another Samsung instead.

    An update, in case anyone else is experiencing anything similar ...
    After troubleshooting with various technicians at various companies, it appears the problem was actually a faulty router. I don't understand why my Samsung had no issues with it (or my laptop) but when I replaced it with another router I had kicking around, the BlackBerry had no problem connecting and it has been about three hours so far without disconnecting at all.
    I suppose I'll come back here if the problem recurs but, in the meantime it appears to be just one of those weird things. So I guess the moral is to try everything, even if you don't think it could possibly be the cause, because you just never know.

  • Connect to a network printer for air print, after disconnect from the wifi iphone keep pop up a message saying the printer is offline. How do I disable this annoying message?

    Connect to a network printer for air print, after disconnect from the wifi iphone keep pop up a message saying the printer is offline. How do I disable this annoying message?

    Hey ronniefai,
    Thanks for the question. I understand you are receiving a prompt that your printer is offline. This may be due to a printing job that is currently in the queue. Are you able to see the print summary when following these steps?:
    Viewing the Print Summary
    You can view the Print Summary by double-tapping the Home button and swiping to the right to reveal Printer Center. Then tap Print Center.
    Note: Print Center is available only while printing is in progress.
    via AirPrint Basics
    http://support.apple.com/kb/HT4356
    If so, see if you can cancel the job. If not, what happens when you re-connect to the network that the printer is on?
    Thanks,
    Matt M.

  • Why does my mac keep disconnecting from my Wifi?

    After downloading Yosemite, my computer (macbook pro) keeps disconnecting my home wifi.  I had no problems with my wifi before and my roommates have no problems with it still (they do not have macs).  This is only happening at home though, when I go anywhere else, my wifi stays connected.  I have tried deleting/forgetting my wifi network and reconnecting, restarting my computer, i searched through my settings but I don't know what to do. It disconnects like every two minutes. When it disconnects and i go to reconnect, the wifi is still there and has full bars, my computer just doesn't stay connected to it.  If anyone has any idea what to do that would be awesome!

    Hey sydthekyd5,
    Thanks for the question. I understand that you are experiencing issues with your home Wi-Fi network. Check out the following resource for relevant information regarding your symptoms:
    Wi-Fi: How to troubleshoot Wi-Fi connectivity - Apple Support
    http://support.apple.com/en-us/HT202222
    Symptom: The network connection drops unexpectedly
    - Your Mac may not not stay connected to your Wi-Fi network reliably.
    - Your Mac may stop accessing the Internet during use.
    Solution
    Use these steps if your computer disconnects from its Wi-Fi network unexpectedly.
    1. Check your range to the Wi-Fi router and reduce the effect of interference.
    If your computer is too far from your Wi-Fi router or your environment has too much Wi-Fi interference, then your computer may not detect the Wi-Fi network properly. The easiest way to check for range limits with your Wi-Fi network is to move your computer or your Wi-Fi router closer together and make sure that there are no obstructions (such as walls, cabinets, and so forth) between the router and your computer.
    See Potential sources of wireless interference for more information about interference and solutions.
    2. Try connecting to a different Wi-Fi network. If your computer works fine when connected to a different Wi-Fi network, then the issue may be related to your network router or ISP. In that case, contact the manufacturer of your router or your ISP.
    Thanks,
    Matt M.

  • My phone will randomly disconnect from the wifi and when I retype the password it says it is wrong. It will eventually work but I have to wait for a message to pop up on my screen to allow me to retype the wifi password.

    When I first got my phone it worked perfectly fine with the wifi. Although later on I began to have problems connecting it. It will randomly disconnect from the wifi and when I try to retype the password it tells me it is wrong, although it is right. It will eventually work but in its own time, a message will pop up and allow me to type in the password and it will work. But sometimes it takes an hour or more and sometime it takes 10 minutes. I've seen where other people have had this problem but I don't know how to fix it. I'm not sure if it's an issue with my phone or if it's with my wifi. Does anyone know how to fix this?

    Does this happen with all Wi-Fi hotspots?  A specific one?
    Have you tried forgetting the Wi-Fi connection and then reconnecting to it?
    What about power cycling the Wi-Fi router?

  • HT202157 my apple tv is disconnected from the wifi intermittently, the problem is not the wifi as it only happens to the apple tv. that I can do to fix this problem.-

    my apple tv is disconnected from the wifi intermittently, the problem is not the wifi as it only happens to the apple tv. that I can do to fix this problem.-

    That doesn't rule out a network issue, as it can impact devices differently. Intermittent issues are most often related to wifi issues. Try connecting via ethernet. Go to istumbler, netstumbler or similar to get a report of the network, look for signal strength and noise.

    Some users with various Wi-Fi problems have reported that they were given the following instructions by Apple Support, sometimes with success. After completing the procedure, you'll have to recreate all your settings in the Networkpreference pane. Make sure you know how to do that before you begin. Taking screenshots of the preference pane may be helpful.
    Step 1

    Triple-click anywhere in the line below on this page to select it:
    /Library/Preferences/SystemConfiguration
    Right-click or control-click the highlighted line and select
    Services ▹ Reveal
    from the contextual menu.* A folder should open with an item named "SystemConfiguration" selected. Move the selected item to the Trash. You may be prompted for your administrator password. Reboot and recreate the network settings.
    *If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combinationcommand-C. In the Finder, select
    Go ▹ Go to Folder...
    from the menu bar and paste into the box that opens by pressing command-V. You won't see what you pasted because a line break is included. Press return.
    Step 2

    Step 3

  • PC keeps disconnecting from home hub.

    Got a very annoying problem, for some reason my computer keeps disconnecting from my home hub. Its got much worse recently and I have no clue what is doing it. Sometimes it can stay disconnected for a couple of hours and when you finally get the connection back it says it cant connect to the Internet. Also my network adaptor cant find my hub but it will find my neighbours even though the hub is just down the stairs from my PC. Signal it good-excellent. There are 2 other computers using the same hub but the are totally unaffected by this.
    Would really appreciate some help.

    from your comments I assume you are using wifi 
    you can try downloading inssider3 (istumbler if MAC) and then run it. This will show the broadcasting networks round about you and their channels including your own. If you then enter your router and change your wireless channel to a free or less congested channel.
