(Q) very slow wifi - Xperia Z1 Q&A, Help & Troubleshooting

Hi there,
I'm new here.
I have an problem with my wifi speed.
My speed will not go faster then 150kb/s.
First, in the beginning of my z1 there was no problem. But then Sony deside to update the software, sims to be good. However, the download speed is now terrible.
The weird part is, when i shutdown my wifi on the phone, an put it back on, it will go's like normal, but only for that specific download. When I go downloading something else, it will download with the slow speed again. How weird is that?
What have i done :
- Change broadcast Channel on router.
- Test more than one router
- Have taken more than one diverent Rom
What do i have:
Sony Xperia Z1
Android version 4.4.2
Rom by iHackers v4.1
Bootloader unlocked
Please help! Can't even streaming to my ChromeCast!

[Q] Xperia T disconnects from Wi-Fi automatically.

My Xperia T disconnects from Wi-fi automatically. One minute it is connected and running fine but suddenly it disconnects and shows out of range. Strangely this happens only on stock or stock based rom. Wi-Fi runs fine when running CM10.1. So i guess its not hardware issue. I would use CM10.1 but its so unreliable. I missed several important calls due to sudden reboot in CM10.1 and in stock I cant use my Wi-Fi properly. It disconnects automatically. I have tried every wifi setting combination but none of them work. I am frustrated because of this. I have treid every firmware from from ICS to latest .145. But nothing is helping. Is there some kind of wifi power saver that i can disable or maybe i can update wifi driver in my xperia T. I am in desperate need of solution. Please help me. :crying:
Tough one... have you gone into Settings, then Power Management? There is "extended standby mode" option on my phone that seems like it would turn the wifi off while the phone is idling.
Also, is this on any wifi connection? Or mainly your home wifi? It would be worth having a look at the website of your router's manufacturer to see if there is a new firmware available for your wireless router.
I would like to suggest trying stock firmwares from other regions but I don't know how safe that is. Is your phone an LT30a? LT30p?
Right now I'm using LT30p_9.1_A.1.141_PL on my LT30a (Bell) and wifi is quite solid.

yes the extended stand by mode is unchecked. This happens on every wifi. I have been to my friend's home to check for it. It did same there. My phone is LT30p. thank you, I will try other firmwares as well.

Yes but not all functions works,camera is upside down ,autobrightness is broken+ some problems with internal storage and other problems....If someone know how to port wifi drivers from TX than it would be great but for now im using Cyanogenmod because on TX firmware was more bugs than on CM....

unbranded
unbranded MEA
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...

Xperia V internet Connection problems

Hello,
Im kind of new to this, so sorry if i say something derpy. I installed CM 12.1 (http://forum.xda-developers.com/xpe.../rom-cyanogenmod-12-neo-s-homebuilds-t2967819) and everything is amazing, except one thing - data connection is acting really weird. Whenever I try to load up YouTube app or anything else, really, that doesn't use data connectivity continuously, it always shows that there is no internet connection. The icon is there, and it kind of works, i tried speed test, and it showed full LTE speeds (even tho it did take some time to find the "best server"). Wi-Fi works just fine. I tried downloading APN settings from my carrier, but that didn't help. It worked just fine with stock android and my last ROM. I'm using unlocked Xperia V LT25i, European version. I haven't seen anybody else complain about this, so if someone could help, i'd very grateful

[SOLVED] Wifi issues with Z3c on Marshmallow - possible fix?

Since Sony made the official non-beta Marshmallow available for Z3c many people are complaining about wifi issues: wifi connection is very frequently being dropped. I was searching for possible fixes but none helped.
I wonder if anyone knows how to fix those problems and I also wonder if this issue is only present on some special configurations (rooted/unrooted/RecRoot...). so I am starting this thread in hope to find the solution.
Please help with any useful info you can...

UPDATE <July 1. 2016>
Problem solved by choosing "Use legacy DHCP client" at Settings > Developer options.
http://forum.xda-developers.com/showpost.php?p=67561668&postcount=6
exact same problem with me-i wonder if a factory reset makes any difference?
No issues here at all (UK EE) non rooted
i wonder if this issue is somehow connected with the rooting procedure, since i haven't heard of it on unrooted devices...
I have the same issue with my Z3c and concept rom, rooted. But I don't have the problem since beginning. I got the problems after my move. Now I have disabled visibility of network. In my old flat I had the WiFi visible and never had problems.

I found a fix yesterday, googling!
http://talk.sonymobile.com/t5/Xperia-Z3/Weak-Wi-Fi-signal-after-Android-6-update/td-p/1113392/page/6
It goes like this:
From settings->developer options I choose "Use legacy DHCP client", which use Loliopop insted the new one client, and everything is OK now.

I tested it and it works. No more wifi droping!
After following the advice reboot the phone (I also did a "Network settings reset" under Settings > Backup & reset before rebooting).
Poor Wifi connection on unrooted xperia x3c

I have acquired Sony Xperia z3c only recently and upgraded the new device straight to MM, so no experience with previous versions.
I think there may be some improvement using the Lollipop DHCP client, however compare with my other phone Samsung S4 mini (Kitkat) the wifi performance is considerably weaker. Measuring wifi with speedtest.net app I get such different results as 6-8 Mbps with Samsung and 2-3 Mbps with Xperia z3c. At other places where the wifi is even weaker (1-2 Mbps), the S4 mini is still capable of downloading stuff, whereas xperia hardly connects and if so then keeps dropping the connection. I wonder whether the issue is possibly linked to the MM battery optimization, as there is no more the option of not saving battery using wifi. Within the optimized processes I've picked "com-sonymobile-wifi" to not optimize and seems to me that the wifi connection has improved slightly.
Any other suggestions in terms of improving wifi performance through power settings?

I did everyting what mentioned earlier, but nothing helps, I flashed back KitKat, and the issue is still here. It doesn't matter if it's rooted or unrooted. So I flashed back the original firmware and sent back to the local sony service because I still have guarantee for it. Now I'm waiting and maybe they can fix it.
WiFi has been spotty on this phone through all the versions of Android it's had. The legacy DHCP option is new to me I may try out out if i get anymore wifi issues

[Help] Z3 Compact Docomo - Wifi issue on Android 5 and 6 !!

Hello everyone! I'm a newbie to XDA. Sorry for my bad English
I'm using an Xperia Z3 Compact Docomo. Recently, I found out a problem with wifi on my device. I've spent time to search for this for several time, but it's not like any opportunities there:
My device is running on Marshmallow. The Internet is very, very slow( of course I don't enable any Battery Saving Mode). I have flashed my device back to Lollipop, but the problem was still there. Then I flashed my device back to Kit Kat, the connection was ok. I thought that this problem is my device's firmware. However, when I used my device on Marshmallow to connect to my neighbor's wifi, there no problem with Internet connection. Then I flashed back to Lollipop and connect to my neighbor's wifi, the connection is still ok.
I think this problem related to DHCP, Mac address,... or something else like that but I don't know how to fix.
Now I'm running on Kit Kat in order to keep normal connection with my wifi. But I don't want to stay at this version because of the ancient interface, you know :crying:. I want to go to Lollipop or Marshmallow. Can you explain why and help me how to fix this problem ?
Thanks you!
