Wifi Drops

[BeadyEye]

n we please get a comment from Sony regarding the wifi drops with this device?

This is unacceptable for a flagship device. I posted a thread a few weeks back regarding this, and specifically asked for it not to be deleted, or merged with the 4.4.4 issues thread. A day later and the thread was missing. This is not specific to 4.4.4. This was an issue with 4.4.2 as well, and it still has not been fixed. I am not the only one with this issue. You can find others on here, and plenty of others on xda with the same issue, not to mention the number of people who don't take to the Internet to post bugs and issues with their phones.

Can someone from Sony please offer some helpful advice? Not the typical cut and paste response "boot into safe mode and try, then do a device repair via pcc if safe mode doesn't pin point the problem".

I've repaired my phone many times with pcc (in 4.4.2 and 4.4.4) to no avail. I've tried safe mode to no avail. I've flashed an ftf file via Flashtool to no avail. There is nothing more I can try. It is not a router issue as every other device connects fine to my router. It is not a hardware issue as my device connects fine to my parents wifi. My dad's z2 also has the same issue on my wifi network as well. Its a compatibility issue with the z2 and certain routers (or settings within the router) and nobody from Sony has been helpful to date. I've called Xperia care, and their technical support has been useless. I end up coaching and teaching them about the z2, and the features and settings on it.

Im very disappointed in Sony's after sales support (or lack of). I spent $700 Canadian on this device and get absolutely no support for it. Look around the forums, there's plenty of people saying the exact same thing (even with other issues). If Sony does not fix this issue with the next update, this will be my absolute last Sony product I ever buy. It's one thing to have horrible after sales support, but to have it while selling a flawed product is just plain unacceptable. Especially for this price.

Just giving this thread a bump as I saw others with wifi issues in the recents.. Disabling stamina mode helps, as does changing the channel on the router. But the issue still exists! I should be able to use stamina mode and have working wifi!

Just to follow up with this issue. Xperia Care has again responded advising me to send my device in for repairs. This is quite unbelievable. They expect me to go over 2 weeks without a phone, just so they can come back and conclude that there is nothing wrong with my device? I've already told them it is not a hardware defect issue. If it was, I would have this issue on ALL wireless networks.

I think what I will do is wait for the android lollipop update, if that doesn't fix it, I will buy a cheap backup phone, and send the device into their repair centre. I will also attach an email with it telling them that I have already confirmed it's not a defective piece of hardware, and that I'm only doing this to prove it to them. I will then receive my phone back in the same condition (possibly data wiped lol), and provide all documentation to the ceo of Sony Canada. I will explain to him that this is one of the reasons why Sony is failing in the phone market.. Xperia Care is a complete joke. They do not read or try to fully understand the problem. They just say "software repair via pcc, if that doesn't work, send it in for repairs". Since that is the case, Sony may as well abandon their Xperia Care department entirely, and send automated emails advising of the steps to troubleshoot your problem on your own. They could save a lot of money by closing their incompetent, useless, money draining Xperia Care department. Very disappointed in Sony once again. Hopefully someone who actually cares and has power within this company reads this and does something about it.

My Z2 was not actually having this problem until I updated to Lollipop. Now I have the problem, very frustrating indeed especially when using the phone to skype for example. I would greatly appreciate some support from Sony on this. Did you ever manage to solve the problem?

Believe it or not, the lollipop update fixed almost every wifi issue I was having. I know google brought some wifi fixes into the code, not sure if Sony did as well, but whatever they updated, it seems to be working pretty well for me.

Hi,

Both my wife and I have a Z2 and after the update to 5.0.2 we both had issues with wifi. I first discovered it when I was out of reach from the 4G/3G network.

I searched the Internet, rebooted the router etc and eventually I did a reset of my Z2 with PC Companion. Still no solution..

During this time my Samsung Tablet was working fine via Wifi from the same place in the building.

This evening I found a way to "fix" the problem and I can recreate the problem every time on both my Z2 and my wifes Z2.

If Bluetooth is on, the wifi trough put is almost every time zero / time out, sometimes 1mbit/s. With bluetooth off, through put 50 mbit/s every time and I'm standing in the same place. I have done this test more then 20 times, on each telephone with the same result.

I have just sent a mail till Sony support.

At least I have found a workaround, and hopefully I can help someone that have the same problem

🙂

Well I guess I jinxed it, because I've noticed lately that the wifi drops are back. Status bar shows full connection, but apps just hang sometimes. I have to constantly hit refresh within the app for the wifi to kick in again and start working. Didn't have any issue with firmware 726, but now that I've updated to 28, the issue is back.
