[Q] Weird wifi problem - always scanning never refreshing SSIDs - Sprint Samsung Galaxy S III

I've searched and seen a ton of wifi threads but couldn't find this particular problem.
Something is making my S3 wifi get stuck scanning constantly. This part seems to be a common problem; the weird thing in my case is that even though the phone is constantly scanning it is not refreshing the list of SSIDs. So even though I am home and it is scanning, it doesn't show my SSID or any of the SSID's in the vicinity. It shows a bunch of SSID's which it picked up at some point while I was out and it is stuck on them. Also, when this is happening it doesn't show the "remembered" networks which are not in range. Usually you see all those at the bottom of the SSID list.
If I turn wifi off then back on again nothing changes. It displays the same obsolete list of SSIDs and keeps scanning.
If I toggle airplane mode then the phone actually refreshes the list of SSIDs and it stops constantly scanning. And it shows the list of remembered SSIDs which are not in range.
Keep in mind that updating SSID's isn't totally broken. When I leave the house it's working fine on my home SSID. After I leave it is obviously updating the list of SSIDs for a while but at some point it just stops updating the list but keeps scanning.
Any ideas? I'm stock & rooted 4.3.
I feel like I've posted a million issues in the last few days. I recently got a refurb S3 from Sprint that is a complete POS. My old phone was rock solid until the power button crapped out on me.

have you tired a data reset?
just backup first (incase it doesn't work) factory/data-reset, wipe partition cache and dalvik cache.
if it doesn't work you can restore your backup to get back where you are now.

I haven't tried that. I appreciate the advice but this is usually the first thing Sprint tech support would recommend. I come to XDA for better suggestions
Besides, I can't easily make a backup, I'm rooted but still have stock recovery so no way to make a true backup.

Absolutely true, though sometimes the easiest and most obvious steps are actually the ones that work.
good luck, I hope you find a solution that works for you.

[Q] wifi "avoided poor internet connection", screeoff kills connection

im trying for a week now to get around an issue that is costing me my nerves and renders my phone useless, especially on travel without roaming and data-plan. after screenoff my nexus kills the wifi connection, after some time though, 30 minutes, 1 hour, it seems to change. my company uses skype as the primary means to communitate and i'm just cut off, won't receive important mails, messages, whatever.
when i switch my phone back on wifi starts up again, if im quick enough the settings reveal "avoided poor internet connection" in the hotspots status. so basically it looses the signal for a moment and is not able to connect back on its own. i read 4.0.1 had a setting to circumvent that but since 4.0.2 it's gone. of course keep-alive-during-sleep is checked to "always" in the settings and i tried just about anything, changing basebands, factory resets, cache wipe, etc. nothing helped. the weirdest thing i that the battery stats to not reflect it, the blue wifi line is uninterrupted all the way.
i searched and found dozens of people complaining about this but no solution anywhere. they switched phones and had the same problems still. from little fragments i collected it seems that samsung devices had this issue before, cm7 supposedly fixed a hardware driver that had issues with certain wifi devices on certain frequencies.
im on AOKP b27 now (powersaver on or off with setting to untouched or "leave on" made no difference), leankernel, xxkl1 baseband. today i went back to stock 4.0.2 to see if that does something. still, has anyone here similar problems and maybe even solutions? what about the cyanogens "nexus one sleep fix" i read about, anyone can provide links or informations?
Did you try settings - wifi - menu - advanced - keep wifi on during sleep - always
Sent from my Galaxy Nexus using xda premium
Try changing that setting. I know 2.x defaulted to turn wifi off during sleep but I thought they changed that in ICS. Either way that sounds like the problem.
its not that setting, it's the first thing i checked. it's set to "always" and it should never kill wifi in theory. from what i have read by now it seems more of a wider problem, a software or hardware related issue affecting all nexus devices. most people don't know about it since it only fails for certain routers having certain settings (which other phones digest without problems though). i also never knew it until i had to stay one month in a place with a wifi-hotspot my phone doesn't like. my gf's s2 has no problems at all, neither have our laptops.
here on xda people have switched their devices because of that problem, got new ones and the problem persisted. i have installed roms, kernels, stock-images, basebands, nothing helped and i am sure the problem won't go away if i exchange the device. i knew i'd probably not gain much by asking again, threads like this can be found here, on rootzwiki, google, etc., but i was hoping to gather a little more knowledge. to read about cm7's patch for a similar issue on the nexus one gave me hope that something must be out there ...
btw, stock ICS seems to have the best reception by now, it stays connected for hours. but once it looses it, it won't re-connect aswell. my experiences are worse with AOKP. and it sucks because i love that rom so much. i guess when i'm home again it wont bother me since my own wifi is okay - but man, here, in another country it really hits me.
i had the same problem, seems like the connection would drop when the wifi signal is weak regardless of what settings you choose. i saw this problem on 4.01 and 4.02 stock, and apex rom. i had to switch to a router that could broadcast a stronger signal. i would get about 80-90 dbm with the old router and the new gone give 60-70 dbm. it seemed to have fixed the problem, i havent seen my gnex drop the wifi since i got the new router a few weeks ago.
Ive heard some people have a bug with wifi sleep policy setting not working. But mine seems to actually work. Set to "never" is the best choice and after hours of screen off my wifi is still connected.
Maybe try that setting a few times to kill the bug.
“never"should actually kill wifi immediately after screen off I think. If it doesn't that would be just another bug. I read somewhere that for some people setting it to never resolved the issue but i tried pretty much every setting by now, nothing worked out though. I became so desperate I installed wifi monitor apps that reset wifi after they figure it got dropped, but not even these patches could revive it in some occasions. The only thing that works for sure is switching on the screen every now and then.
It's a wifi sleep policy. So never = never sleep.
Weird, mine says "keep wifi alive during sleep": always, when plugged in, never. our I miss something and there's another setting I haven't tried yet.
this may fix ur problem... for rooted phone

do you have " avoid poor connections" unchecked?

How do you get that? It says "Keep Wi-Fi on during sleep", which implies "never" would always keep the Wi-Fi off during sleep.

Obtaining IP Address issue

I have searched for this issue and there are TONNES of threads about it and a lot of proposed solutions but none of them work for me. I have been using this HTC Incredible for some three months now and have gone through various ROM's including some Sense based, CM7, a couple ICS ROM's and MIUI. But every one of them gives me this problem with the wifi at work. The phones finds the network, connects to it, authenticates and then gets stuck at Obtaining IP Address... and then repeats the cycle.
I used to have an iPhone that worked well with the same wifi spot. My friend's Nexus running ICS connects just fine. But my phone exhibits this problem with this wifi spot and a bunch other public spots it has connected to before.
From reading various threads, it happens when Android remembers the last IP address it got at this spot and tries to assign itself that but fails. It does not learn to ask for a new one. Which is verified by the fact that assigning a static IP, then going back to dynamic IP address makes it refresh the IP request and work for a little bit. Then it goes to sleep and the same agonizing cycle starts again.
Is it because of the hardware? Is it because of the Kernel? Does anyone have a clue?
I have tried Wifi Fixer app and that didn't help. Another person has listed three other apps and how those did not work for him (so I didn't even try them).
At this point, this issue is so frustrating for me. Can anyone recommend some more ideas for me to try? Different ROM's, different kernels? Anyone? ANY one?
This happens to me intermittently when I come home. Multiple ROMs and kernels, no rhyme or reason. When I notice it, I restart the phone and have to turn WiFi back on. Then it works fine for a day or longer. I wonder if it's a bug that's triggered by background processes.
I came across this possible fix while searching for something else. Wifi Won't Connect
Also, I would not be so quick to write off those other apps you mentioned, it is very possible that the person who said they did not work had something different that was causing the Wifi to not connect/obtain IP.
Thanks guys. I have installed a new Kernel and will try it as well as the above suggestions in the next couple of days and report back. Here are the suggestions made so far:
1. Turn wifi off. Restart the phone and turn wifi on.
2. wpa_supplicant renaming
3. Other wifi fixing apps.

Have you tried forgeting the network in the wifi settings menu and then try connecting again?
Yes, I have tried forgetting and starting from scratch again. And with the new Kernel, it just doesn't connect at all. Gets stuck in the Getting IP address loop even for the very first time. I tried #1 but that didn't do anything. I cannot rename the wpa_supplicant because I don't have the USB cable with me and the ROM doesn't let me access the internal storage in ES Explorer. And since I can't get on the wifi, I can't try the other wifi fixing apps (#3).

[Q] losing wifi connectivity- full bars but all gray

so, I've read around here on the XDA forum about problems with wifi connectivity where we have full bars for wifi but they are gray and you are not getting out. many describe my situation but I've not seen any real solutions...
my problem is that I can connect to my wifi router without issue but then a random amount of time later, sometimes fairly quickly and sometimes it's hours later, I will pick up the phone and see full bars but they are gray and I'm not getting out. I can try opening a terminal window and pinging the gateway/dns servers and can't even reach the gateway.
things I have tried:
- turned off MAC filtering on the wifi AP
- switched from a 5 GHZ wifi on the AP to 2.4 GHZ net on the AP and vice versa
- manually set the phone wifi preference to one or the other (5 or 2.4)
- battery pull on the phone
- delete network settings for my AP and reconfigure
I have not yet tried a static IP config on the phone but I can easily try that... {edited to add} well, I tried static config and that didn't help at all...
one other tidbit of info, I have a work Blackberry with wifi and it never loses wifi connectivity so this is a problem unique to my Nexus.
I'm running Cyanogen 10.0.0-toro and no, I haven't tried a full wipe and reload yet.
thoughts or suggestions?
I'm not trying to threadjack here, but I just wanted to share my experiences.
I've been have the exact same thing happen to my phone (Nexus maguro). I've tried every JB rom I could find, several different kernels and my wifi eventually always goes grey on me. All network activities stop. I'm back on stock everything right now and it still happens.
It happens on my home wifi as well as work wifi.
I'm about to puttstock ICS on my phone and try that out for a couple days.
Anyway, good luck with your problems, i'm going to follow this thread in hopes you'll get a solution that may help me.
If I do figure anything out i'll post back.

seems that this is a topic that has been posted on a bit over time with no real single culprit or fix. I'll post back if I figure anything out... I know in the Cyanogen thread, I saw info that stated that the MAC address of the phone was changing and I'm going to try and determine if that is happening to mine.
I have the same issue. Sometimes even when i pick up the phone, if i look fast enough i see that the Wi-Fi bars weren't even there! Thats only 1 out of 5 times though. The other time its usually just grey bars. Sometimes it actually will click back and they'll flash to blue and grey 2-3 times and then go solid blue. Then sometimes like you, they'll stay grey. I've tried everything too...reverting to stock, Different kernels, ROMs, routers, static IP, 2.4 or 5ghz, full auto mode. The only fix that makes it a little more reliable, is using Wi-Fi PM Fast. But even that, is not reliable. I'd say its about 50% reliable then, for a huge sacrfice in battery life. For me i've noticed this started to happen with 4.2. Before that i never had a problem. All other devices though no problem. My Nexus 7 is just fine. But the galaxy nexus, no matter what router or where i am, the Wi-Fi is totally unreliable. For me, it happens within 2 minutes that it will disconnect most times. Then 1 in 10 times it'll be fine for 10 hours.
In all honesty, i've given up. Just come to deal with it. Use mobile networks when i'm not needing to download. I can download files and stream music just fine too. If there is traffic going through, it never disconnects. But when its just sitting there without traffic, it disconnects, or, loses connection to google servers i should say.
well that's not good to hear...
I installed stock 4.0.4 a couple days ago and have not had my wifi go grey on me yet.

yeah, I love Cyanogen so not willing to go back to stock... waiting for them to finish 10.1 and I guess I'll see how it behaves then.
Hi all,
Just to say that I have the same problem. I have been upgraded from ICS to 4.2 and nothing had happened but I had to downgrade to 4.1.1 (AOKP Build 4) due to other issues and after that I started notice the WiFi problem.
At first I thought it was when the screen went off, but I has happened with screen on too. I have to turn WiFi off and the back on to connect properly again, very annoying.
As I said I started noticing this after I downgraded, but then again, I had used AOKP 4.1.1 before without this issue. I think that it is time to change my phone :/

I'm on Muzzy 4.2.2 and I'm currently having the same problem. It's not a new problem since I remember having it months ago (disabled my phone's WiFi because I kept missing emails and other notifications - grew tired of dealing with it). I thought it was my router, so I swapped it with a newer one recently, but it carried forward (old router was TRENDnet Draft N and the new one is ASUS RT-N66U).
I would like to know how to properly troubleshoot this problem.
I'm glad I didnt have to create a thread for this. I have been facing this problem quite a lot. I can confirm that WiFi works absolutely fine until 4.1.2, whether it is stock or CM10 (I havent tried the other ROMs yet). I have faced this problem only from 4.2. It still exists on 4.2.2. Happens on all the ROMs I have tried till now including CM10.1 nightly as well as the stock factory image.
When the phone is sleeping, it seems to lose WiFi connectivity and when woken up, the WiFi bars is grey though it is full. If I am very lucky, it will turn blue automatically. Most of the times, I have to switch WiFi off and back on for it to connect properly.
Anyone knows the root cause for this? In case this has been discussed in any other thread?

have you posted this information over in any of the threads where the developers are working such as Cyanogen in an effort to bring this issue to the forefront for more visibility?
I have had those wifi problems with every android version and rom I had on my GNex as far as I can remember.
Sometimes it will be able to reconnect but sometimes I have to disable and re-enable wifi to get it back.
I too thought that it might have been my crappy router as I have had multiple problems with it over the years (some Linksys router).
This is really annoying because it won't receive any e-mails until I randomly decide to have a look at my phone. :/

trust me, I understand your frustration... some days, I can go almost all day without loosing wifi data throughput and other days it won't last 10 minutes without going to gray bars.
unfortunately, no one is sharing any fixes which tells me that no one has a good handle on the problem.
Same issue for me on stock Android 4.2.2. Leave WiFi on overnight and when I wake up its connected to WiFi but gray bars...

The update to 4.2.2 drivers have fixed all WiFi issues for me. For the first time since 4.1 I can now use WiFi optimization now. And WiFi is fully reliable.

same thing happened to me on toroplus sourcery 5.1, after trying everything i could think of and talking to one of the devs, i finally did a fresh download of rom and gapps. wiped cache,wiped dalvik, factory reset, wipe system, deleted android folder off of storage then installed the fresh download of rom and gapps and its been working great for me since. hope this helps.

i just know ever since moving to a 4.2.2 kernel that has the 4.2.2 drivers my wifi has been stable. I know there was a post in the anarkia thread with the ak kernel that had the drivers. but i believe most any 4.2.2 kernel would have them implemented. i do have the newest bootloader and radio too. but i know as soon add i got the 4.2.2 drivers all issues were resolved wifi wise. of course i think if you have a 4.2.2 kennel you'll have them.

[Q] Mobile DATA keeps turning on Automatically

Every since Verizon pushed the Lollipop update to my N4, my "Mobile Data" turns back on all by itself after it has been disabled. It even turns back on when I am connected to wifi.
Has anyone else experienced this and if so can you please explain how I may fix this.
Thanks in advance.
Not exactly that but I have noticed that now I'm always on 3g when I'm usually on 4G all day long same area this is crazy
Mine is also randomly turning on Mobile Data too after the Lollipop update. I have a small data allotment with VZW, this could send me into overages.
I seen on one thread, searching through your downloaded apps to find out which ones have "change network connectivity" in the permissions. I happen to have 6 of them. Some you can disable, but it removes the updates, other you cant disable without removing it.
Another recommendation was hitting settings from the pull down menu, wifi, advanced, then uncheck the "smart network switch". Mine wasn't checked to begin with, so I'm out of ideas til I start removing apps one by one...
The data has been turning on by itself during sleep time on my Note 4. It caused the phone to use 500mb of data in one nite. My data is always off, wifi is only on when using the phone otherwise it's off too. I called Verizon and they have no clue. This is my 2nd new Note 4 for myself & my wife, nothing but problems. Think we are going to switch to anything other than a Samsung phone.
Well, I've systematically removed all 6 apps one at a time. The Youtube and Facebook apps, I was only able to disable them instead of removing them completely. In the end, the phone still turns on Mobile Data by itself. This must be something internal with Lollipop. I have a small data allowance and I'm afraid its going to go over simply because it wont stay OFF even with WiFi available!!
I would call customer service and have them ship you out a replacement. This is our 3rd phone and hopefully it will work as it should. Good luck
Outcast,
I've had my Note4 since it was released in November. It didn't have this problem with 4.4 Kitkat. It's something new with Lollipop and I doubt a new phone would solve this problem, could be wrong.
How involved is it to go back to Kitkat?
I'm not chancing voiding my warranty. They replaced my phones by them and not by request. Our phones get hot and get a warning then shuts down, apps close constantly and the phones consistently reboot on their own. Then the data turning on by itself. The other problems I don't think are software based but hardware failures. The data can very well be software related.

I have the same problem and i used up so much of my data when i am at home where the wifi connects automatically on everything else. On kit kat this never happened and i am attempting a downgrade so you might want to try that.
I was having the same problem with mine. I also live on the edge of 4g area, so it was constantly swapping between 3g and 4g. In addition to using some data it was killing my battery swapping between 3g and 4g. Using almost 10% per hour when not being used. I disabled most of the verizon stuff, support and protection, Verizon navigator, caller name id, message+, and verizon location. I turned off facebook location reporting in the app settings, and disabled google location. I did all these a couple at a time and would reboot to see if it fixed the problem and after all those were done i rebooted and wiped the cache and the prblem was gone. I turned google location back on so far and its still working the way it is supposed to. It shows a greyed out 3g symbol and my battery life is much better. My phone sat off the charger all night and only dropped 4% and in 5 hours of moderate use its down to 77% left. Wish i knew exactly which app was causing the problem to help you out better but hopefully you can try those apps and settings and get the same results.
Well it worked for about 3 days, but this morning data and wifi were both running again.
Data usage Samsung Galaxy Note 4
Been having the same problem even when I disconnect data ten or fifteen minutes later data is back on. And I've noticed even if I am connected to Wi-Fi data trumps it and I end up using a ton of DATA when I've been connected to Wi-Fi all day, getting seriously upset cause I never used this much data before.
I have same problem with my Note3 running Lollipop. Have tried every suggestion I can find to turn off data, but it is still runs, unless I am on wifi. Data is set to off, 4g symbol in notification bar is greyed out, but data is still on. I have found forums all over the Web with other people with this problem, but no solution yet. My phone is unlocked but not rooted.

Strange Bluetooth/WiFi interaction after MM update

Hi everyone, I'd really appreciate any help anyone could give me in solving this problem...
I upgraded to MM a few weeks ago and at first had some odd WiFi issues where the phone would not connect, or stay connected very long. After about half a day of tearing my hair out, clearing my cache, and reinstalling apps it all seemed to "come good", and had been ok for a few weeks.
A few days ago, however, everything went bad again. Here is what is happening:
On my 2.4Ghz wifi network, when the phone is woken up using the power button or double tap, WiFi does not work. The phone reports that it is connected to WiFi, and (according to the Ping Tools app) has an IP address, but there is no connectivity to the outside world (or even to my router or NAS box). After about a minute or so, the connection magically "comes good" again, and the WiFi works normally. This is very frustrating as while the phone is asleep it has no IP connectivity so I don't get any notifications for email/messages etc. I have the default "yes" setting for the "Keep Wi-Fi on when screen is off" option BTW.
I have discovered that if I switch to the 5Ghz WiFi network on my router then I do not get this behaviour - the WiFi stays connected while the phone is asleep and there's not the same period of no connectivity when it wakes up. Unfortunately the 5Ghz network doesn't reach to the front of my house so this isn't a viable solution.
I have also found that the odd behaviour does not occur if I disable Bluetooth on the phone. Since I use Bluetooth audio in my car, it's a bit of a pain to disable/re-enable it but it's the workaround that I'm currently using.
The strange behaviour does not occur if I reboot the phone into Safe Mode... the WiFi stays connected while the phone is asleep, and 2.4Ghz WiFi works straight away when the phone is woken up. This seems to indicate that an app might be the culprit.
To try and diagnose this I have
- cleared the cache and rebooted a number of times, to no avail
- done a factory reset and reinstalled my apps from Google Play, but end up in the same (broken) state
- changed the default channel for 2.4Ghz WiFi on my router several times
So I'm at my wits end now. I guess I could do another factory reset and reinstall my apps manually, one by one, and see which one (if any) breaks things. But I'd like to to try and avoid this. Does anyone have any suggestions as to how to determine what could be causing the problem?
Phone is an H815 running Android 6.0, V20a-EUR-XX. Totally stock, locked bootloader.
Sorry for the lengthy post.
I have approximately the same thing. Switching Bluetooth doesn't help in my case. I had to wipe cache from within the phone to make it get better again.
One other thing was to throw away my aluminium bumper. Do you maybe have one ?

Oh, I got excited at your case suggestion as I got a new case a couple of weeks ago which does have an aluminium bumper. But I just took the case off and alas the problem remains.
Unfortunately clearing the cache doesn't work for me. I also found a setting under Backup and Reset to reset network options but this didn't help either.
Next step might be to reinstall the OS or try the repair option in LG Bridge. Unless anyone else has a better idea?

Tihs issu not MM specific exist on LP
Try another chanel (In router)and use only N 2.4 Ghz
But is see you try..
Go and use warranty.!!!
I think I've fixed it. I just started uninstalling apps and checking to see if the behaviour persisted after uninstalling each one. After uninstalling TuneIn Radio the WiFi started working with Bluetooth enabled again. I reinstalled all the apps that I uninstalled (including TuneIn) and everything seems to be working again. I doubt it had anything to do with TuneIn - just a weird interaction of who knows what. It's not terribly satisfying and I suspect it will happen again, but hopefully this thread will help someone who might have the same problem.
