WiFi issue - Disables itself - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

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.

Connection Dropping :(

Hi there
First time poster, shame it has to be a cry for help!!
I've got the touch HD, and I love it, however over the last week or so its started losing its HDSPA and 3G connection and dropping to phone only. At first I thought this maybe network related (T-Mobile), however it seems to do it in all locations.
I'ver noticed when it does it, the data connection slider in the settings tab, is switched to off, and as soon as I flick it back on, it picks up the signal fine (only to lose it again after a random amount of time). I've downloaded Tweak HD and set the internet to always on, however that doesn't make a difference.
I've not installed any custom roms, its the factory build, really hope someone can help
Thank you
Do you see the connection drop while the screen is on or is it after you have put the phone in standby (screen off)?
It seems to be random, I can be halfway through browsing the web and it'll drop or just coming out of standy.
The most common time seems to be when I do a send/receive on the email tab, it shows the 'H' icon then as soon as it starts syncronising, it drops out to radio then I have te re-send to get it to connect again.
I seem to recall the same thing happening to me back when I was using the stock rom. For the first week everything was fine, then the connection would drop when I turned the screen off or even when the phone was on. If you've tried setting the connection to "always on" and that does not fix the problem, then I would next try and download Schaps Advanced Config and enable/disable the different power management settings. I've suggested this to a few others for disconnect problems in standby and it seemed to work.

Mobile network stopped working MoDaCo 1.1

So, my brother and I have been running MoDaCo 1.1 core for a couple days now.
My phone has stopped connecting to the mobile network. All it says when I try to connect is "Standby for connecting to mobile network" with a green checkbox. I also notice now when I select the checkbox to connect it turns green instantly and shows that standby message. Before it would take a couple seconds to connect and turn green.
I have tried changing the mode of operation and it still doesn't want to connect. There is no 1x or EVDO in the notification bar. Wifi and GPS still work fine.
My brother's phone is still working fine. I have no idea what the problem can be.
Anybody else having this problem with MoDaCo 1.1?
I think that it has something to do with airplane mode. I enabled airplane mode yesterday, then turned it off. I didn't realize my data wasn't working after that since I don't use it while I'm at home. I am not sure if that is exactly the problem, just trying to think about how it could have stopped working.
I've noticed mine will do this at random on the MoDaCo 1.1 ROM. Every now and then I'll look at my phone and realize my EV symbol at the top is gone and I have no network connection. When this happens both the option in Settings and the small on/off widget on one of my home screens say it's still turned on. If I turn it off and back on, then I just get the "Standby for connecting to mobile network" message too. The only way I've found to get it to work again is to reboot the phone.
FYI this same problem happens to me with the stock ROM, even when it wasn't rooted. I've noticed it only happens when you turn airplane mode on, and then off.
Hmmm...I never touch airplane mode and I never saw this happen once in the month that I had the phone with the stock ROM. Maybe my problem is unrelated then.
Even when I reboot my phone it still doesn't work. I have tried messing around with the widgets turning things on and off multiple times and still nothing can get it working again.
I just went back to an old nandroid backup from before I put MoDaCo 1.1 on the phone and it seems to be working again. I'm going to put 1.1 on again. I'll use it for a while and try to recreate the problem to figure out exactly what it is.
Sprint/HTC has to fix that. it's a bug.

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 turning on by itself

Hi,
My H990DS has been bothering me for a couple of days as WiFi turns itself on without any kind of intervention.
Turning it off manually or having the phone restart does not help. I made sure the latest apps installed make no impact.
Playing with Developer Options made no difference.
I am ready to Factory Data reset.
Anyone experienced something similar ?
Thanks,
My 918 always shows wifi active in GSAM's graph, even when set to "Never" under the "Wifi on while inactive" option in system settings. I ended up just downloading Leandroid from the play store and setting it to disable the wifi radio, and renable it periodically to check for push messages. Seems to work fine with doze and standby time has improved.
Under settings, location, three dots top right, scanning, turn wifi scanning off. It turns back on anytime you use wifi and you manually have to turn it back off each time.
Mine (918) does this all the time. Im thinking its a 7.0 thing. There has been a few exceptions where it has stayed off. In my case I drive through a busy section in town and it constantly connects to the 20 or so open wifi spots so I turn it off. Well once I pull into the garage at home its magically back on.
Maybe something to do with networks it recognizes, Xfinity wifi wreaks havoc on it as well.
As soon as I uninstalled the latest apps, the issue disappeared. Not a single exception in 24 hours.
I suspect a Sip Client had caused the problem.

What!?
That sounds utterly horific for the battery, nevermind privacy concerns. I thankfully haven't experienced anything similar myself, but I've only ever used custom ROMs so perhaps that's the cause. But that sounds terrible.
