bizare wifi behavior

well, my wifi is acting wierd... reception is good and it doesn't disconnect too often, theres just this little anoying thing!
everytime roughly 3-4 days after i flash a new rom my wifi simply refuses to connect to network, and not a specific one, any network at all!
and it stays like this for a couple of hours and then all of a sudden it picks up a a networks and it works fine for a while, untill i happens again...
i've tried restarting and taking out the battery and turning the wifi off for a while, nothing seems to help, he just decides on his own when he is whilling to connect again....
if i flash a brand new rom the problem disapear for a few days but then it comes back... i'm assuming it has to do with some sort of a cache that is filling up with loads of crap and ruining the wifi activity but i tried googling for this and found nothing..
ideas anyone? (btw this happens on all roms: stock, existenz, beanstalker etc...)

its a hardware problem and not so uncommon look here

if you can take it to a customer support and if you cant sell it and again if you cant, then just get along with no wifi/bluetooth/NFC check all of them you should have problem with them too

absolutly not related, my NFC and bluetooth works just fine, i don't need to press hard anywhere...
and my wifi works just fine after a fresh rom install... so it's defenetly a software problem...

to me that sounds like the start of it because mine was the same at the first few days flashing a new rom or something would help alot but then i just found out the only thing that was helping it to get fixed was the heat from the device not the rom, but it doesnt hurt to play around with it a little so go ahead and try some other roms or repairs.
you see good reception for wifi
you try to connect
at the authorizing or connecting you will see only one point of signal and connection would kinda like disappear.
this is how it was for me but at the first days it was random it was connected good and ready, when i would left the phone in stand by after a few minutes it would DC, so i thought its kind of a sleep mode malfunction or something but after a few days almost 1-2 weeks it turned out to be hardware problem like ohers so if you see any symptom like that start looking for service centers.
but i hope it would be a software problem for you, so good luck.

Well, once he connects he stays on for days, no problem there... Just sometikes he refuses to connect... Pressing the nfc button doesnt help...

What Wi-Fi channel is your network on and have you tried 5GHz?

Didn't look into those things, but it happens with all networks except ones without passwords
Sent from my C6903 using Tapatalk

Have you tried deleting wpa_supplicant.conf in data/misc/wifi and reconnecting to the network? (this will delete all saved passwords and settings for known wi-fi networks) also try to disable Auto IP in advanced wi-fi settings

Well the phone is qith my sister now, I got a new z1 so far wifi worka for her, it stoppes for a few hours yestarday but came back, I might try to flash. 310 and see if it works better with it. And the Wapa_sup sounds like a good idea. Btw z1 is also jittering some with wifi, it's a global Sony problem...

temp solution?
Well, it is probably a hardware problem. I have had the same problem, everything looks fine, but you can't connect to any network.
So, searched, reinstalled, etcétera, nothing worked. Untill I read a crazy solution link://talk.sonymobile.com/t5/Xperia-Z-ZL-ZR/xperia-zr-wifi-association-rejected/td-p/516275/page/4
and found out that if you put pressure on the back of your pone right at the NFC chip, with a finger or so, the Wifi will come alive again.
Personally I had to hit my pone's back at that exact spot with my finger (for not damaging it with excesive force) a few times, but then suddenly it worked.
So, I am convinced it's a hardware problem. Hope it works for other people too.

i had the same problem with sony xperia zr, and some other guys had it too, there is something seriously messed up with sony wifi drivers...
good part is it apears to be a software issue and can be fixed if sony whould give a damn...
http://android.kul.is/2013/09/sony-xperia-zr-wifi-problem.html
here is a detailed post about it, although sony told this guy eventually it was a hardware problem i'm pretty sure it's not, had the same issue on my zr, flashing a new firmware usually fixed it for 3-4 days untill it began again.
i suspected it was some app that i installed that messed up the wifi, anyway i got a new xperia z1 and my zr went to my sister, after a factory reset wifi works fine for her now...... so no idea actually...

My problem was most likely HW, because flashing new firmware including the one in the service centre did not work. But it looks like Sony has a lot of problems with the Wi-Fi chips in general - so the range of possible errors is quite broad. If it was a software problem, hopefully new update fixes it.
EDIT: The Xperia article is the most popular article by far on my website - which is sad.

it only happens to me once. the problem was solve once i off the wifi n on it.

Same here. I went into my router config and enable the Packet Flow Accelerator. No issues after that. Seems like Sony wifi chip eats a lot of packet data.

Made a factory reset and it's still happening at home and in the office, so it must be the Xperia Z Ultra as other devices work fine in both locations.
How to fix that???

Happen With Me Too
1.136 Indian Branded FTF
To Solve This I Have to Switch Of WiFi and again on it
me using connectify latest version
and when i tried to connect with my bro's lumia connection stays stable
sad sony

I had the same issue and the wi-fi worked again after I turned on the "Auto IP Support" option in the Wi-Fi advanced menu. Hope this helps.

Might work for other Z series...especially after Custom ROm or updated to 4.3
Hi all just wanna share with you all to all the Xperia ZR users who are facing problem to connect to any 2.4GHz networks. This is an official solution I found after weeks of testing and research. In the end, the driver is not loaded properly or by default, custom ROM created the havoc. So this is a solution finally will end all the Xperia ZR owners WiFi woes:
I noticed that when running ADB GUI, there is this file missing from /System/Data/Misc/WiFi called "WCNSS_qcom_cfg.ini" .
I'm using ADB Helper Version 4.2.0.0, under BUILD.Prop Viewer tab, choose wlan.driver.config it points to that location. I downloaded somewhere from Xperia developer forum website. Then i modified and modified until i found the solution.
in this file modified the line gDotMode=3 (which is running in N mode only) to either 1 or 2 which s "a" or "b" mode.
I reboted the device and the wifi works and N mode is disabled meaning you wont be able to connect in 5GHz mode anymore. But you will be able to connect to all the CURRENT 2.4GHz AP ...yayyy!!! I read somewhere where ICS android allows you to Enable or Disable 5GHz scanning of AP. But later were removed. 4.3 updates sometimes also i found out will WIP this configuration or maybe Developer forgotten to include this as well. I hope Sony Xperia developers will look into this.
Now, my phone can connect to any 2.4GHz WiFi.. I would be willing to help just drop me an email at [email protected].

Re: Somehow it worked for me...
I faced the same Bluetooth & Wi-Fi problem...
For Bluetooth I have got the replacement..
For wi-fi.. I did the tethering..
I created the Hot Spot in another phone and then access that hot-spot from my Xperia ZR..
Luckily it obtained the IP address of Hot-spot and started working
Then without switching off the wi-fi of my phone, I deleted the Hot-Spot connection and tried to access my already created wi-fi router setup fom ZR...
It clicked and started obtaining the IP address of my router..and its working fine from that day...

[Q] WIFI is not functioning as it should

Hello guys I bought an Xperia Z1 last week and the wifi reception is very poor and i've read my threads and they say change channel and turn off wifi optimization and turn on Auto IP thing and change security code mode on the router and i tried all of them but i still get slow internet connection and my brother also got an iphone 5s and when we use speedtest and put them next to each other he gets 8mbps and i get like 0.3 to 2 maximum mbps
So do you know anything i can do to fix this problem

Try using this app to find best channel in you neighbourhood:
https://play.google.com/store/apps/details?id=com.farproc.wifi.analyzer
If that fails flash different ROMs like iHackers or even better CM11. If you're still getting same results then call Sony and tell them. They might replace your unit due to defective radio.

Yh my WiFi was poor in every room expect living room (where router was located). I never had this problem with GS2 and Galaxy Ace. At the time I couldn't flash CM cause of the UB camera issue. So I used WiFi Analyzer to find best channel to my surprise auto had set it to Channel 6 which almost everyone in the neighbourhood was at. After tinkering with router I found that channels below 11 work best. After tinkering with the app I found a rating system that suggested best channels.
The reason why I suggested you flash other ROMs is to find out whether its a software issue if every ROM fails then its a hardware issue unless your phone WiFi works with other routers. If the latter was the case then something is wrong with your router.

I saw many threads and people saying that its working better with cheaper routers and routers that are b/g/n and it worked better in my friend's house and he got a d-link router but anyways am gonna try to flash CM or Slimkat cause am already rooted and i got dual recovery but is there any stable CM built cause i went to cyanogenmod's website and it says Experimental builds and Nightly builds only and do they work on locked bootloaders?(Slimkat and CM)

Wifi, Wifi tethering and Bluetooth is not working

Hi,
I have Xperia ZR C5503 phone about a year. Until 2 months ago I was using Android 4.3. When Lollipop update distributed I upgraded it to 5.0.2.(official)
But sometime after the upgrade my phone started not connecting wifi. It sees the available networks but not connecting them. The signal drops to lowest level about a second while trying to connect and it fails. Also I was using my phone's wifi tethering feature to share my internet to my pc. However wifi tethering is also not working. I enable it but I think it can't work as router. And lastly, I tried to send a file to my phone via bluetooth and it also enables but no other device sees it. I also have low sound on the phone and I can't hear people I am talking to.
So I got frustrated this saturday and downgraded to official 4.4.4. But it was same. Later I unlocked the bootloader and rooted my phone, installed recovery software. With that recovery mode I cleared all caches but the problem still countinued. Lastly I installed an unofficial modified kitkat to my phone but those problems still appears. I don't know why this phone is so problematic for me. I don't know if it is software related or hardware related. Now that my warranty is no longer valid.
Could you give me some ideas to attempt to solve these issues?

Hi,
I had dropped my phone maybe 1 or 2 times but not from high heights.(~ a meter) But that was more than 5 months ago. I am having this issue since last 2 months and I am sure that I didn't drop or harm my phone in any way. However I wash my phone, do you think that could cause that? Just effecting wifi and bluetooth components?

It's not true about dropping the phone make that errors appear, there are many people with same issues, this phone have manufacturing problems, it's not software
My brother have same problem and he never dropped the phone. Just take a look in Sony forums.
Btw, my brother's phone lost Bluetooth connection, NFC, WiFi, Sometimes WiFi works making some pressing in the NFC spot some seconds, but sucks anyway :/

Wifi problem
my sony xperia zr has the same wifi problem it says scanning trys to connect the signal drops and again starts scanning..
I stopped the wifi service and restarted my phone and the wifi worked for a day and again the same proble.
Do anyone has a solution for this??

I have been facing the issue of wifi not connecting, since my upgrade to 5.1.1.
My research has led me to believe that the issue may be software based. However I'm not an expert in the field. And i was thinking of downgrading back to an older version of lollipop when the wifi was not dropping.
Can anyone advise on whether this may be a smart move, or a completely useless one?
Also is there a diagnostic protocol I can go through that could help me figure out for sure whether my wifi is busted physically, as some of you suggest here.
Thanks
Josette

I've tried the method "settings global put tether_dun_required 0" but when i reboot my Z5, the value comes back to 1 ... (and of course wifi tethering is not working, going thru USB is ok)

I'm discussing various points here. Check out everyone of this point and get a fair idea from where problem is originating.
1) Go to WiFi Settings > Keep wifi awake during sleep. Here the string value should be "Always"
2) Under stock firmware there are numerous battery optimisation. Some of them kill WiFi so battery can saved. Now disable this features if you want no drops in WiFi.
3) If both of don't work, head over to Xperia ZR General > Search for your specific device FTF. Flash it via flash tool. This should reset all wifi drivers. Don't opt or apply any battery features and use WiFi. If still issue exits then you're in bad luck.
4) Check for other WiFi access points. Check your own router's webpanel and see somewhere broadcasting and multicast signals are ticked. Also check your WiFi is at 100% of it's performance ( 100% transmit power)
5) Hardware issue. Most of the software part is not causing issues so it's safe to say a hardware issue is causing this. Now, long time ago when 5.0 was released for our device I read article regarding ZR. The user had constant WiFi drops. His issue was that his WiFi soldering was poor inside hardware. He soldered it again and his wifi drops were no longer a problem.
People also experience various bluetooth/tethering issue. It's important that people should gain knowledge about firmware flashing techniques so that device would get reset and you yourself could diagnose the problem. 1 in 0.7k unit has software/hardware issue in manufacturing. Sony provides diagnostic app, search in play store ( I'm not sure about this). Hope this answer helps many.

hii.. so did u get any solution for the problem ?
i am facing this problem since one month. i tried rebooting my phone many times. i even tried factory reset. but nothing has worked till know.
if u have any solution please inform me.thanku

Ok, my warranty expired too! I also tried software repair and still not working and i now see that Bluetooth also is not working.

Hey guys. I fixed this on my phone about a month ago. So far no one has commented if it has helped them or not, but here is my post again. Let me know if it helps.
I had this problem on my Z3c for a while (as well as no wifi or bluetooth). My device is well out of warranty. I received a RMA number last week to send it in in hopes that it would be an affordable fix. I was getting it ready to send out today and decided to try a couple more things.
As others have said, I went in to the diagnostics and test the WiFi (passed) Bluetooth (passed) and GPS (failed). I then decided to test WiFi and Bluetooth a couple more times to see if it would eventually fail. It never did. After that, I went to turn WiFi on manually and to my suprise.... it turned on! Bluetooth and GPS were also magically working.
Before this I had tried numerous factory resets, diferent android versions, different roms (without unlocking the bootloader) with no success. I'm not sure exactly what happened, but hopefully it can work for some of you!

I have exactly the same problem but only one thing is different that my Bluetooth is working. There only problem is wifi. I belive that is no hardware problem. There must be some kind of glitch in software where you accidentally doing this things jumped over. I have tried your tip. No success. Im going to do this every day to see if I have luck. My Bluetooth and wifi passing test every time GPS is failing.

Yes, please do post back your results. I'm not sure if what I did was a fluke of what, but I was shocked when I saw my WiFi turn on. Almost every other post I have seen about this either stops getting replies or the OP sent it in for repair numerous times.

I have done exactly the same things like you described. No luck. Strange my Bluetooth is working only wifi can't be switch on. GPS is failing on test like yours. What has the GPS to do with wifi? I don't know if there is any connection.

I forgot to mention I was on the latest factory lollipop image. I'm not sure what you are on. Are both WiFi and Bluetooth passing the tests?
I'm not sure if they are connected or not.

This is no solution. There is not problem with my router. I have done it many times anyway. There is problem to find any wifi point.

Nobody?

When I was trying to root, I ended up using KingRoot and replacing it with SuperUser afterwards. None of the other methods seemed to work for me.

Ok. I have rooted my phone with giefroot. Very simple. You only follow the guide. But now I have rooted phone and gone to to root Explorer and can't find the file I should delete.

Sorry, I can't help with that. I don't see it on my phone either. I have no idea what that folder is or what it does either.

F*ck, I have same problem, wifi won't turn on. Few times after phone was turned off for long time it worked but mostly just stuck. Bluetooth works so can I be sure it's not a hardware problem?
