[Q] Stock 4.3. killed i9505 wifi? - Galaxy S 4 Q&A, Help & Troubleshooting

Good evening, everybody.
I have an international i9505 and just updated the system to Android 4.3. through KIES last week. My phone is not rooted and I do not intend to do so.
Yesterday I was using the phone at home, with the wifi turned on, like I always do, when some messages about unstable internet connection started to pop up, followed by a notification about that new function that automatically turns the connection from wifi to mobile in case of bad signal.
After closing everything, my wifi just died. It does not turn on anymore. When clicked, the toogle button becomes light green and then turns off again; at settings/connections, the button remains turned off all the time, never green.
I've already rebooted, removed the battery, restored factory settings and downloaded the update again and nothing had worked so far.
I've also downloaded some "wifi fixer" apps at Play Store, but also with no luck. Most of the apps just crashes when asked to turn on the wifi.
I've read lots of threads about bad wifi function after update, but I dont think my case is similar to any of them, because I didnt flash a custom rom, neither the problem is related to the connection with the router; but turning on the wifi adapter.
All the other stuff (mobile data, gps, bluetooth, gestures, etc.) are working fine.
I really have no idea what to do anymore.

Hi i am a brazilian user and after update i have some problems with wifi connections.
But i really think that is an issue on 4.3 rom

Bell JK4 - Wi-Fi Discussion

After upgrading to JK4 via Kies I've noticed some strange Wi-Fi behaviour. It seems to manifest at different times and for no apparent reason, so I'm starting a thread to see if a) anyone else has this issue and b) if so, how does it manifest for them.
First manifestation: after turning on Wi-Fi through Notifications the text switched to "On" but the Wi-Fi symbol did not turn green. Going into the Wireless and Network settings on the phone caused a temporary lockup, when it did let me in Wi-Fi was showing "Error". A reboot of the phone fixed it, temporarily.
Second manifestation: after turning on Wi-Fi through Notifications the text switched to "On" and the Wi-Fi symbol turned green, but it did not connect to my wireless network automatically like it should. Going into the Wireless and Network settings on the phone caused a temporary lockup, when it did let me in Wi-Fi was rapidly switching from a "Turning on" state to "Turning off". It did this about 10-15 times in a few seconds then went to "Error". Turning on and off the Wi-Fi again solved this issue.
Every time I solve this it seems to come back within a 24 hour period. I didn't have this problem (from what I can see) on JK3. I factory reset before and after flashing to JK4, and I flashed JH2 back just to be on the safe side beforehand.
Let the discussion begin!

I quickly tried out after reading your post, and I did confirm your first issue happening, but only when I turn my Wi-Fi on and off really quickly. Also my phone didn't lock up as you described either. Basically, I could only make that issue to surface once I turn off the Wi-Fi, and then turn it back on as soon as my phone reports it is disconnected. When I go into Wi-Fi settings, it does say "Error" there, but if I check the "Wi-Fi" there again, it connects automatically.
I almost never use Wi-Fi because I get 6GB of data, but I can see this becoming a very annoying issue if you have to use Wi-Fi frequently.
Edit: Actually, I ran into a different issue just now. I kept on playing around with my Wi-Fi, and confirmed this happening: Wi-Fi text turns to "ON" but the icon doesn't turn green. When I go into settings, it says "Turning Wi-Fi On.." or something similar and is stuck there. I wasn't able to turn on nor off the Wi-Fi. Reboot fixed issue...for now I guess.
I have also had this issue but I believe it has to do with trying to turn on wireless when your preferred network has a very weak signal. When I'm next to my router, I can turn wi-fi on and off rapidly with no issues. I have only had the issue in my room which has a much weaker signal.

i was having problems with my wifi today...i wasnt able to pickup any wifi signals and i couldnt manually turn the wifi on either...i got a few force closes on some apps and decided to reboot the phone, hopefully sovling the problem...instead i got stuck in the boot loop at the i9000m logo and now my internal sd card is done....hopefully i can return this pos at bell(im on rogers) and do a hup through rogers for the iphone4...at least thats a stable device.

I've never tested right beside the router, but my room is next to the room which has the router so I would think I'd have a fairly strong signal.
Interesting, though...

I tested my Wi-Fi pretty much right beside my router as well...like less than 3 feet away. My phone was reporting it was seeing an "excellent" signal.

I find my wifi on my phone to be pretty solid.
I have an occasional issue where it does not see my wifi router at work, but all I do is turn it off / on and off she does. Just happens with the work router. Never had an issue with my linksys at home.
I've experience this issue with JH2 and it was caused by a change to fast in the settings. Just give your phone some time to connect and get identified on the network before you turn it off ans don't torn it on right after you disconnect it and you should be fine.
Been having the same issues since upgrading to JK4. Wifi gets stuck in "enabling" state occasionally when it try to turn it on. Sometimes I have to go as far as restarting the phone to get it to work again. Not a huge deal but still a nuisance.
I have seen both of these situations occur once after applying JK3 from Odin. It was shortly after booting it up for the first time including the "ERROR" text. I attributed it to a one-time glitch and it has not come back since. When I am home I force WiFi on and leave it in that state until I leave the house for work the following day so I am not constantly messing with the settings.
I get a similar issue butt only when activating my mobile AP.

I've been having a similar issue with my wifi since upgrading to JK4. I've gotten the "error" message on enabling wifi, but as others have mentioned it may be because I'm re-enabling it too quickly after turning it off. However, in one instance yesterday I tried re-enabling it several times after turning it off via the control widget and was ultimately forced to reboot before it worked again. Also, this morning I found that after leaving home and coming to work, I was still only seeing the wifi hotspots near my apartment rather than the ones in my new location (one of which I have saved and automatically connect to). I had to reset the wifi to find the local hotspots. Other than these wifi issues, I'm really loving JK4 so I just hope they get sorted out.

Problems with WiFi Connectivity Since the Last Update....

Guys,
I updated my tab a few days ago. Now the market looks different but unfortunately I'm facing another irritating problem which I have no clue how to solve.
Every time that I turn off the tab, and let it be idle for 10 minutes, when I turn it back on, the WiFi icon will show no bars - which translates into no internet connectivity. That happens while the WiFi button is still pressed (green in the pop-up menu). In order for the device to connect to the net I need to turn the WiFi OFF and than ON and it works.
I checked the WiFi sleep configuration and they are set to "never turn it off" I also rebooted the device but with no change.
Please let me know what to do... as this thing sometimes just drives me crazy.
Thanks.

Flash a custom rom bro. Otherwise you are stuck with Samsung's awesome bugs. If you don't want to flash a custom rom there isn't really much you can do about it considering you're not rooted. What did you update to? KMP???
I did the regular Samsung update -the latest one that was released a couple of says ago. The problem with rooting is losing the coverage I have for insuring the device... which I'm reluctant to do. I'm sure it has a solution somewhere...
Yes I confirm.
This "reconnect" issue is being discussed on many forums with no solutions yet. (except custom ROM)

WiFi issue - Disables itself

Rooted Samsung S4 MDL ROM OUDhs SWM Touch Recovery v1.0.3.5
This problem may have started about 11 days ago when for the first time my phone ran out of battery on me. (Had used the NAV a lot that day). I'm not sure if it is connected or not. I'm not sure when I first noticed WiFi was turned off. I think it was over the weekend, but who knows.
Problem: When I leave an area where I am connected to WiFi it disables WiFi and will not reconnect anywhere until I turn WiFi back on. When it detects the loss of the WiFi signal it will show the list of Access points it sees. I don't see it that often because usually it is in my pocket. I just watched it once or twice to see what happens as I drove away from work or home. It will go on to AT&T mobile data and stay on it even if I am in an area with a saved WiFi connection (such as home or work). I essentially have to remember to turn on WiFi anytime I get home or to work.
While looking for a problem I found a setting in the WiFi settings section under advanced. The setting is Check for Internet service "Auto switch between Wi-Finetworks and mobile networks" This was unchecked. Last night I checked it. I figured it may have unchecked itself or something when I ran out of battery last week. Well this didn't help. When I got to work this morning I still had to toggle on the WiFi.
Any ideas?
FYI, I am still on stock ROM. Anytime an update comes down it downloads it, if I reboot, it won't install so that is a good thing. I still have root and SU.
The autoswitch would do it. When you turned the auto switch setting back on did you do a full reboot? Sometimes that's the only way some settings will take action properly, even if it doesn't tell you too.

I didn't do a full reboot after changing it last night. i did this morning however after checking which recovery I had for sure... so I guess I'll find out if that took care of it when I leave work in a few hours.

Note 2 wifi problem: Please Help.

My wifi was working very well. One day suddenly it went off. Initially I thought it was a connection problem, but eventually I discovered that the wifi toggle switch refused to start. It was stuck.
I did not upgrade or change anything (Currently running stock android 4.3.) In a bid to correct it I even did a factory reset. But wifi issue remained.
Did everything mentioned in various YouTube videos. But in vain.
The only way I can turn it on is by switching off the phone, removing the battery 4 a minute and restart. Wifi worked but to 5 to 10 min only.
Removing battery every time 2 start wifi is nuisance.
Pl advice.

I would advice you to do the following
=>Disable all power saver settings
=>Remove any battery saving App
If it doesn't work try
=>Installing the newest Official Firmware from Samsung(4.4),Download it from the sam mobile site
If that doesn't work well then i cant help you anymore
Hope that helps and hit the thanks if i helped
Dear Sammy,
I did exactly the same. Installed the 4.4.2 but a new problem has emerged. Wifi shows connected. I can also see the white wifi icon on status bar. But in fact is not connected. Can't open anything. Not even router configuration ip address.
To make sure it was not a modem/ router issue, I checked d connection on another phone. It was working perfectly.
Here too I tried switching off for couple of minutes but on start it just shows connected when it is actually not. (Confirmed several times on other phone)
Plz help.

[Q] Lollipop WiFi issues - takes long time to turn on or not turning on at all

I had CM11 on my Nexus 4 and did a full wipe, then flashed the official Lollipop image (using flash-all.sh script). The process went smooth, without any problems.
Now, I am having WiFi issues. When I turn on WiFi from quick settings it changes the icon, but doesn't connect to the network yet. If I try to access WiFi settings it opens them up, but I can see only the actionbar and a blank white screen. No networks shown. Sometimes I even get "The app is not responding dialog". It sits like this for about 30-60 seconds and after that it connects to the network and I am able to access WiFi settings.
Sometimes I can't turn WiFi on at all. Quick settings don't change the WiFi icon to the ON state. If I try to turn it on from the Settings, the switch does literally nothing - not even "Turning WiFi on..." shows up.
I tried to reflash the system - still get these issues. Tried reflashing just the radio module - didn't fix it. No idea what to do. KitKat worked just fine.
Does anyone else have similar problems?
Same issues, but on a Nexus 10.
I have exactly the same issues as you, but on a Nexus 10. Running LRX21P 5.0 Lollipop.
+1
I used Wugfresh 1.9.6
Downloaded and installed LRX21T
Did a complete wipe (cache and factory reset)
Did a selective restore of ~75 apps from Google backup
Played with the machine for hours.
Rebooted, now got no wifi
Anyone suggest a workaround?
EDIT: I came across this post in the Nexus 5 Thread , where he suggests changing your router's channel to something below 12. I changed mine from 13 to 8 and now wifi seems to be working.
EDIT2: Sadly the above was a red herring. The problem seems more complex. Hopefully Google will release a fix soon

I don't think my problem depends on the available WiFi networks. But thanks for the response.
I have the exact same issues, Wifi doesn't turn on at all. It doesn't matter if I press the quick settings button or the button in the menu. It says Wifi on, but nothing happens. After the screen goes dark, Wifi turned itself off again.
Any suggestions? Thank you!

I'm having the exact same issue. Wiped with ADB and flashed LRX21T factory image from Google's website. No error codes during flash.
Wifi is great - if you leave it on all the time. As soon as it turns off, it will NOT turn on. I get no error message, no timeout like it usually does when Wifi isn't working properly, no crash report. Nothing. Just a stalled Wifi acting like it's turning on. If I exit Wifi settings page, and come back, it shows as being off. Turn it on, and it just hangs the same way.
So frustrating.
It's for sure not the network I'm on, as it also doesn't turn on when I'm not near Wifi, or when I'm at a friend's house. Rebooting the phones makes the Wifi work again...until it turns off for ANY reason. Then we're back at square 1.
I'm having this same issue...
My WiFi seems to turn itself off. Then there is no way I can get it to turn back on unless I reboot the phone.
Very frustrating.
I have the same issue.I sideloaded the OTA and everything went great,no errors during the installation.I was on stock 4.4.4.
When I turn on the Wifi it takes around 30 sec to connect to a network.If i click on the Wifi menu in the setting it usually freezes or I get a black screen.After that Wifi works fine,but another thing I noticed it doesn't remember new networks.I don't know if a factory reset would help...
Anyone find a solution yet? Did a factory reset eliminate the problem for somebody?
I got the same thing. Currently, I'm using Power Toggles to do the on/off setting.

Are you saying that Power Toggles fix the problem?
I'm facing a different issue. Whether I have WiFi on or off, it always appears active in the battery usage stats ('scanning always available' is off)
WiFi was off when the screen was off from about 3 am to 2 pm.

I am having the same issue. very frustrating. it was working perfectly last night on my home network, but now it wont connect to my work network. it has the same issues as everyone else. the wifi toggle will turn on, but it will not show any networks. then after a couple of seconds it will turn itself off.
^^i am having that issue as well. the battery usage stat page is showing wifi as on even though it is off.
Have the same issue. After some standby time, turning Wifi on again, it showed me networks where I am not close to anymore and didn't show me the actual networks where I am right now. This seems to be a serious bug that needs fixing. I don't want to reboot my phone to fix it. Didn't Google delayed the Lollipop-Update because of some Wifi issues?
I have all the symptoms listed in this thread. I filed a bug report too: https://code.google.com/p/android/issues/detail?id=80028&q=LRX21T
Found this thread when this problem popped up for me after flashing the factory images one by one. Might try to find a source-built ROM using a later version to see if it got fixed.
