Z3 Tablet WiFi problems

[shawnigami]

Okay, I have seen this issue in the Z3 phone forum, and it has supposedly been resolved with an update 23.01.A.5.79

Does anyone have the same issue with the Z3 Tablet? I am streaming HD content from my local NAS, and after a while it lags badly. Speedtest shows that I was at 1-2mbit. Resetting the Wifi will put my speed back at 72mbit. and resolve the issue for a while till it happens again after a few minutes. My Z2 phone does not have the problem, nor any other devices. connecting to the same wifi. 

These are my settings....

Stamina Mode is OFF

Low batt mode is OFF

Location based WIFI is ON

WIFI Optimization is ON

Currently my Z3 Tablet is at 23.0.1.A.0.167, and Software update scanned for no new updates. 

Just wondering if anyone else experience the same and has found a workaround?

Does anyone knows if a newer firmware will be released soon that will resolve the WIFI issue for the Z3 Tablet?

Hello,

I have the same issue with my z3 tablet Lte, and I have the same version - A.0.167. 

WiFi speed goes down after some minutes after switching on. Only re-enable helps,but only for some minutes. I didn't check the speed, but noticed the WiFi icon in tray - when WiFi slows down it doesn't show arrows upload and download. 

People from z3 phone thread say some magic with switching off mobile data and airplane mode help, but it didnt work on my tablet.

I hope this is not a hardware problem and we will receive firmware update too.

Just discovered something interesting. Do you happen to be using a magnetic charger? The moment I disconnect the magnetic charger, I see the file transfer rate hit back to 5 MB from 300KB. And once I plug back the magnetic charger, it immediately drops to 300 and below. Doesn't happen with the regular USB charging.

I think you'll should get in contact with Sony Xperia Support.

I'm sorry to hear that you're having issues with WiFi performance.

Could you test if this also happens in flight mode? Hold the on/off button and select flight mode and then enable WiFi under Settings -> Wi-Fi.

Rickard,

It seems this problem appears only when i use my wifi hotspot from notebook (using Connectify tool), though my smartphone samsung works well with it, and other smartphones and even notebooks worked well when were connected to my wifi network.

But i've tested my tablet with 2 wifi public networks, which were provided by router, not notebook, and i havent noted any issues.

I tried with and without flight mode, it didnt make any difference. Only switching on and off helped.

Dont know what to do. I have updated my wifi driver at notebook, but the problem still exists.

I have the same problem. A few minutes after turning wifi on, the download speed drops drastically. Upload speed stays the same. This renders video streaming and Remote Play useless. Only thing that makes the speed go back up is to restart the tablet.

I have the 16gb wifi only version.

And this is after the Android 5.0.2 update.

Is it possible to get a permanent fix for this or did I just buy a 400$ digital pictureframe?

Sorry to hear that.

Have you tried to tap and hold the network, forget it and then add it again? Do you see this issue with a specific network or does it happen with any network?

Thank you for the suggestion to forget and re-enter Wifi network details.

It does appear to have solved the issue, with a more stable connection.  I will continue to monitor...
