[Q] Wazzup with wifi? - Xperia Z2 Q&A, Help & Troubleshooting

Im just surfing on wifi, and than a couple of hours later it says authentication failed for the same source (in my house).
If i turn the wifi off and on it fixes this.
Running on the newest fw.

Yeah I've found that the wifi is a bit hit and miss. It's like it drops out but the icon remains. It's annoying when streaming music as the connection times out and the music stops. There's nothing wrong with my internet connection as all other devices stay connected 100% of the time.

WiFi Dropping or won't stay connected

my wifi keeps dropping. Is anyone else having this issue.? It only stays connected about 2 minutes and then disconnects. I have tried to reboot the phone with it does not seem to fix the issue. One other thing it does not reconnect either.
Gman

It was smart WiFi. Add to add home router to this app and now I'm staying connected. Thanks!

Seems like that only happens once you open the att wifi app.
Opened the app last night and once I tried to connect to a new network it would just keep dropping wifi and disabling the radio. Anyone know if freezing or uninstalling the att smart wifi app fixes this?
I disabled most all the ATT bundled apps right away and have had no problems with wifi.

Wifi issue

My att mega constantly gives me the "wifi unstable" message and internet dependent apps like fb are slow, hulu displayed ok but stuck on buffering when I tried to pkay video on medium quality. This is the only device in my house with wifi issues, and running wifi fixer already. Anybody have any suggestions?
You should try changing your router to accept guest and try the phone there and change the settings to wep instead of the other settings that I can't remember right now

Z2 wifi slow

Having problems with Wifi streaming and YouTube very slow, stop and start every few seconds, got to be the phone as all my other devices stream fine. I have unchecked avoid poor connections in wifi advanced.
Any one else having this problem, will try factory reset.

I've seen factory resets cure a few problems on here so try that 1st but isn't there a .69 firmware available now as well, maybe try that to?

Good old factory reset and it's working fine.....hasn't. Worked
EDIT.......wifi speeds are slow again, can't watch YouTube or stream films, it's only on this device, ipad 2, galaxy s3 and s2 all stream with no problems.
Can't download the 6 free promo films either as download fails after a short while.

My facebook app is not working great in my phone. Youtube has been fine so far but I find my internet quite slow at home as I have rubbish internet speed. Also in peak times I get very slow internet connection.
Wifi speed still slow, only on this device,
Also is the . 69 firmware carrier specific?
No firmware update prompt on my phone.
no option for 5GHz in wifi advanced menu

A couple of things to try:
* test with other access points
* restarting the router
* disconnecting other devices
* forgetting the network on the z2 and readding it
I actually got great wifi speeds with my z2. It was even able to max out a 100 Mbps cable broadband connection on an AC router. Worked fine in n-mode also.

Have you tested on any other networks?
Take a trip to Starbucks! See if you get any better speeds there (and a nice latte, damn I'd kill for one right now).
glas to see im not the only one. Google Play Store @ 0.02mb/s
What kind of router do you have and how far is it? I'm able to maintain 2-3MB/s (16-24Mbit/s) over a distance of 20 feet with walls and everything in between.
After getting my phone last Tuesday ive noticed this little bug as well, sometimes downloading/updating google play apps it'll be like 0.5MB/sec but usually when I use drop down menu and quick settings and turn off wifi(give it about 10/20secs) then reactivate it im back to around 8-14Mb/sec, some apps dont even show a download progress its that fast lol.
I believe it might be a 5Ghz wifi problem as my BT hub shows my phone connecting to 5GHz channel with no way to stop it apart from turning 5Ghz off at the router :/
So hopefully sony will either fix bug or give us more wifi options like already mentioned so we can make phone connect to what we want.
K stand corrected phone can/does switch between 2.4Ghz/5Ghz, router shows phone connected at 2.4Ghz now. Just updated an app while connected on 2.4Ghz and no problem.
Z2 D6503 Wifi dropping issues
I seem to be getting the same sort of wifi issues as previously stated. I cannot hold a wifi connection on the 2.4ghz band fro more than 20s before its dissociated (ie i still have full connection to the router (3 bars) but cannot get through to the internet). This happens no matter what router i am connected to, whether its at home or at work.
I have tried:
Setting the Wifi optimization checkbox off. No difference
Avoid poor connections is off. No difference.
Stamina mode is off. No difference.
Keep Wifi on during sleep is set to Always. No difference.
Sleep timeout to 30mins. No difference.
I have factory reset the phone. No difference.
I have also check to see if it is my router at home. I have switched between every channel available which made no difference. Security is Wpa/Wpa2 PSK AES which makes no difference. I only have the 2.4ghz available on that router at home (same at work).
My Note 3 and HTC One connect to both routers with no problems at all and do not drop out. Same goes with Sony Vaio Laptop.
I have installed Wifi Fixer on my Z2 to see if it can alleviate the problem and it does somewhat. instead of manually having to turn on and off the wifi toggle to reestablish a connection, the Wifi Fixer does it for me.Approx. every 20-30s in its log it will show the phone "dissociating" from the router, and the the app tries to "reassociate" the connection.
I can connect through wifi transfer to my Note 3 without issue, and the same goes for my TV, so it cant be a hardware fault, as the connection is still excellent strength for both (as well as the router, tested with Wifi Analyzer). This is a very frustrating problem as it makes watching youtube movies impossible, and hotspotting, skype calls, etc.....
And dont even get me started on the bluetooth dropouts. I am disconnected from a bluetooth connection every 66-70s without fail no matter what i try. No issues with my Note 3 and HTC One in the exact same conditions. It will disconnect then reconnect straight away with a delay of about 3 seconds, which makes calls and listening to music a VERY unpleasant experience.
Any ideas on how to fix this? I love everything else on this phone but this wifi/bluetooth connection issue is making it unusable.
connecting to my bt home hub 4 via 5GHz band only has solved my wifi drop out problems.

For me slow Wifi resulted in many issues, You-tube video cannot be played, video streaming from a network storage cannot be done, Facebook videos will stop at the middle etc where the most evident issues. I tried everything possible to resolve this issues and searching the internet also didn't help. Finally decided to fresh install, used PC companion and re-installed the complete software, then restored all apps using google backup service. After this there is no issue till now. The software version is the same I had before reinstall. But now the Video streaming and apps using internet become very responsive.
thanks

Is this normal?

I'm connected to wifi but whenever I look at the wifi tab in settings it every two seconds keeps searching for nearby wifi. It seems like that would drain battery. Is that normal and is there a way to stop it?
it's constantly searching under the wifi direct tab as well.

Android has done that from the beginning. It will not affect your battery life.
It only does that when you're on the WiFi screen. Once you select a network, and leave that screen it stops scanning continuously.

Internet keeps disconnecting even WIFI is strong

I have the WiFi version of tab 10.1 and it is running Task's jelly bean ROM, just use it to watch movies from my home NAS and YouTube so feel no need to upgrade the OS.
Recently I couldn't get my internet connection to stay connected, I have WiFi strongly connected, have the WiFi signal bar blue I.e. connected to Google services, but my internet connection is actually not connected, all including the browser, play store , YouTube even my NAS won't work even though everything looks normally connected. Look at the time and date , it is correct, tried turning WiFi on and off, restart, wipe cache in recovery, still doesn't help...
anyone has any idea ?

I think I found a fix for this, I will type it out here in case someone else has the same issue in the future....make sure the SSID is NOT hidden, then connect to the AP with static IP instead of DHCP also provide the DNS address that can be found in the router.
