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.

Hi, if your Z2 has no problems connecting with your dads router but he suffers the same issue when he connects to yours.....have you compared the settings of both routers....possibly a channel problem, i know i had problems before on my router but it was my laptop not the phone & ended up changing the channel as something else was interfering with that particular channel either in my house or a neighbours (i was reliably informed!!) & it did work :smileysmileywink:

I have compared settings between routers, and the only difference within the settings is the channel. My dad's is channel 3, mine is channel 6. I ran a wifi app on my phone and a wifi program on my pc to determine which channel is best for my home router. It takes into consideration all the other wifi signals around to find the channel with the least amount of interference. At my house, it recommended channel 11. When I choose channel 11, I get more wifi drops. When I chose channel 3, I get even more. Channel 6 seems to be the best but there is still wifi drops. My question is, why doesn't ANY other device have this issue with interfering channels? I've tried my old Samsung Captivate, Galaxy nexus, Galaxy s3, OnePlus one, and Asus transformer prime tablet, all with no issues. Yet my most expensive device ($700 z2) has issues. That is my problem!

Are you using a Bluetooth headset with your Z2?

[BeadyEye]

Nope, I always keep Bluetooth off unless I'm driving. This issue is separate from the Bluetooth / wifi issues that exist on the z2.

So nothing from Sony yet? Very disappointed with Sony's support. They make a great product but my God their after sales support is horrendous. There are many users with this issue (I know there's a few threads on xda regarding this). The only thing that has helped slightly is disabling stamina mode, and changing wifi channels. But no matter what I do, I can't seem to completely fix it. Shame that cheap devices that cost a fraction of this device are more stable.

On a side note as well, why on earth did Sony remove the network name under the wifi icon in quick settings? Instead they just have it say wifi as if people don't know what the wifi icon looks like. Aosp shows the network you're connected to right under neath the icon which is the way it should be. Also when you long press a quick setting, it should launch directly into that settings interface, rather than a pop up that gives you one single option to choose from. Little things like this Sony really drops the ball on. I honestly think Sony needs to hire a "common sense specialist" to iron out some of these poorly implemented designs.

Just bumping my thread in hopes that someone from Sony sees it and at least comments.

Well from what I gather out of all of this, the Sony Xperia z2 is not a good device for people who live in cities (due to other wifi signals interfering with a consumers home network). Maybe Sony should target their ads towards farmers and people who have large properties to ensure their neighbours networks don't interfere with their own.

Out of all the devices I've tested (listed above) mine and my dad's z2 are the only ones that have issues connecting to my home network. Neither of us have issues connecting to my dad's network as his neighbours are at least 100ft away. Wifi interference is the only logical answer to this issue. Very disappointed with Sony. I expect more from a $700 flagship device.

Still nothing from Sony eh.. Shall I assume that my message above is correct? That this phone is intended for farmers and people who live in rural areas only? Come on Sony this is getting ridiculous now. People are posting on here with issues and it seems that everyone is getting ignored.

I have emailed Sony Xperia Care regarding this issue, and provided the link to this thread.  It's still ongoing as they have replied twice, both with no solution.  They have also clearly demonstrated that they didn't even read this thread, or take the time to understand the issue, or read the steps I have taken to troubleshoot or fix this issue.  In the very first post of this thread, I confirmed that I performed many software repairs via PCC, all to no avail.  Sony Xperia Care's second response was to perform a software repair via PCC - lol.  I am documenting this on here, and keeping all email correspondance with Xperia Care regarding this issue.
