Wi-Fi authentication problem after a night sleep - Xperia Tablet Z Q&A, Help & Troubleshooting

Hi! After installing Android 5.0.2 to my Sony Xperia Tablet Z, I am facing a strange issue with Wi-Fi connectivity. When at home my device is continuosly connected to wi-fi. But after several hours, basically I notice it in the morning, there is an "Authentication Problem" with wi-fi, and I need to reconnect it. In wi-fi settings I have set "Keep wi-fi on during sleep" to "Always", it doesn't help though. Any ideas how to fix it? Prevously, on Android 4 wi-fi worked flawlessly without any problems. Thanks.

Try connecting to wi-fi manually, or if you have root wipe cache.

[Q] Wifi not working after upgrade to 2.1

I upgraded my X10i to 2.1 and my Wifi is not working. I have confirmed that it is not the router etc. since the wifi works on my PC and my Wife's X10 mini pro.
When I turn on the wifi on my X10 it scans fine and finds my wireless router no problem. When I connect (using my WPA password) everything looks fine and the wireless indicator appears in the statusbar. HOWEVER, when I try to connect to the internet via the browser/market/facebook it returns a message saying NO NETWORK FOUND (no internet connection via wifi) !!
I have already tried -
*reset to factory settings
*reinstall of 2.1 via SEUS
*re-connecting to wireless router with WPA password.
Nothing works!!
Can anybody help?
Is there any way to reset the wifi on my phone?
hi, i had this problem after the upgrade, i changed to the name of my router and then it was fine. try that.
UPDATE - I can get the wireless connection on my X10 to work when it is not encrypted (ie with WEP, WPA etc.)
Now I really don't know what is going on....
Anybody out there to give some advice? pleeeeeeeeaaaase
Thanks
nvm sorry I see that you did every thing.
is just weird had that prob when having nordic now i don't
try installing 1.6 and see if it's the fw or the phone
Sometimes try adding connection manually, then the wifi suddenly detects it from that point onwards..
After i upgraded the firmware to 2.1, my wifi just stops working. When i turn wifi function on, there is wifi logo appearing on the top of the screen and never detects any wifi access point. Anyone knows what is going on? Is that a bug of 2.1? as wifi was working fine with 1.6

I think the 1st time it needs a little push. Try turning WiFi off, back out of settings, back in turn on, go to wi-fi settings and manually select. That worked for me. Had similar with bluetooth.
I have the same issue with 2.1 upgrade and Wifi + WPA2 router protection!!
Wep protection works fine! but for me is not ok it is a weak wifi protection I need WPA2!
please help
I read that wifi fixer may work however I cannot test it untill I reset my modem or switch to Wep....
can some one test wifi fixer? thanks.

[Q] WIFI issue after updating to Jellybean

is anyone having a problem with the wifi after updating to jellybean for s3?
inital connection to WIFI works but after a certain period of time, the wifi stopped working and i need to restart the wifi again for internet to load. IT happens all the time now after leaving my phone with WIFI on.
Constant restarting WIFI to get connection does not happen in ICS..

No such problem for me with JB LJ5 stock or custom!!!
Might be your modem-router....
This happens to me too. It's fine for me at work, but when I'm at home the wifi fails to connect after some time. Are you using dd-wrt at home? I am and I'm wondering if that's the issue.

I find that having my wifi set to always on in advanced I get better wifi and slow drain, having it on wifi off while asleep makes your wifi keep disconnecting and reconnecting. Best way is to switch wifi off when you don't need it.
Also some battery saving apps I've found to stop wifi and need to keep reconnecting, this has to be changed in the settings
wi fi dropped

Hi, Mine is Galaxy Note 2 i317 with Jelly Bean 4.1.1. I did have similar issue. I took two smart phones to Target, one is ICS 4.0.3 and the Note 2 is 4.1.1.
The 4.0.3 never has any issues with wi fi connection. But the Note 2 keeps on dropping the connection. I ran an application wifi analyzer to check the available networks. It turns out that Target has so many routers that are using the same ssid, i.e. "Target Guest Wi-Fi". There are channel 1, 6, 11, etc, as well as many 5Gs. I did an alias for every available connection. Then I pick one of the stronger signal strength 5G and connected to it.
After that no connection was dropped.
The point is that you should try to connect to the strongest signal SSID so that the Note 2 won't keep on dropping the weak connection.
I have no idea why the ICS 4.0.3 can handle better than the 4.1.1 Jelly Bean as far as wifi is concerned.

Same problem!

I'm experiencing the same problem since updating to Jelly Bean 4.1.1 on my HTC ONE X. So it seems to be an Android issue, not specific to Samsung or HTC.
I connect to my home network over WIFI, everything works fine until after a little while my apps seem unable to connect to any data/internet. They just time out or come up with error messages about connection problems.
Sure enough, if I disconnect and reconnect to WIFI, everything starts working again... for a little while.
It's like the WIFI goes to sleep, but forgets to wake-up again.
And there is no indication on the phone, ie. it still shows as connected.

[Q] Strange WIFI connectivity issue...

Hey guys,
OK Ive got a strange problem with one of my Galaxy S3's!
It will not connect to some WIFI connections! It will say 'Obtaining IP address' then 'Failed to obtain IP address' and then loops itself doing the same thing over and over...?
I have two S3's and my other rooted device is fine. The one that has the problem is running a standard O2 4.3 rom (Un-rooted)
My rooted phone is also running 4.3.
Anyone experienced a similar problem? I have had this problem with 4 or 5 WIFI connections now, including my home one which is rather annoying! I have tried the obvious and rebooted my router, which hasn't helped!
Any advice welcomed!

I've had issues with the quality of my internet connection being checked, and then the connection being killed due to "slow internet connection", even on strong Wifi networks. Solution turned out to be to uncheck the automatic network switch in the advanced Wifi settings.

How so, when I have an identical phone sat right next to it with the same version of Android and that phone connects perfectly?
The only difference is one phone is rooted, the other is not (Both running 4.3, just different kernal number and build number)
Well wifi is a function of the kernel .

WIFI issue on Z Ultra GPE with Android 5.0 (Lollipop)

Hi,
Has anyone had similar experience and (better yet) a solution to my issue with wifi connections since upgrading to 5.0?
After the update my Ultra Z GPE losses connection to my home wifi, and other wifi (public wifi,, friend's wifi). Once this happens the wifi app in settings does not see/list the wifi connection. I've tried turning wifi off/on, and refresh but my home wifi (and the public and friend's wifi) do not appear as available. The only solution I've found is to power off and back on again. But doing this several times a day is a pain.
TIA

Well my situation has changed, and perhaps a little less of a pain. Even though in Settings it shows my wifi is connected I am still frequently losing the connection. My apps (i.e., Google browser, Google Now, other apps, etc) do not load/refresh and indicate "No network connection. But now I can resolve the problem by toggling wifi off and on. Better than powering off and on but still a pain.

If your device is rooted try Wifi Connection Fixer ROOT by Zextr. The link is

Thank you for your response. But no my device is not rooted. However, I believe I found the cause of my wifi issue. Separate from my wifi issue I was having some issues with Google Now. So, I uninstalled the Google Now launcher. Guess what? My wifi issue is gone. I have not lost wifi connection since I uninstalled the Google Now launcher.

Wifi Bug

Hello,
to save battery i set the Wifi Energy Management on "Wifi at Standby -> only while charging". From time to time i noticed that my Wifi didn't connect, but i was in wifi range! Did anyone else notice that issue? Changing to "always on" is a walkaround but i don't want wifi always on for energy saving!
I'm on d802 30b stock and i did a Factory Reset after switching to Lollipop and it seems only to apear on a 5GHz network.
Hi.
I can confirm this. With same settings like you, I have the same behavior on all LP roms (tested all official+ ported). This is one of many reasons why I went back to Cloudy 2.2

when i connect to my 2,4GHz network everything is fine.
You should not be worry about being connect all the time to wifi because wifi takes nothing from battery
But now i also get reconnects of my Wifi regardless of whether i choose 2,4 or 5GHz WLAN
