That is not the solution. That is for people that never can connect using 3G connectivity.

Download the Network Profile app, change to another provider then change back to your actual provider.

Just deletes my IE favorites but problem remains...

I have the same issues. I think it's since the last update.

Try this, i've done it (with the dft freedom rom) and aparently it worked:
1- Install the Diagnosis app by typing ##634# on the phone keypad. For Freedom Rom download it from http://forum.xda-developers.com/showpost.php?p=22324890&postcount=42
2-

Wait for it to say success, then reboot. This fixed all my data connection issues after applying this patch."

EDIT: After a day testing the 3g+ sign keeps showing as the prefered connection was 3g but i could easily receive MMS, and most of the time use internet with 3g+ and sometimes no wifi (even if its connected), sometimes looked like if it has stopped loading like if the phone doesnt know what connection to use or looses connection. Switching off and back on wifi normally solves the problem.
Now i've made another change, set network control aquisition order to automatic, mine was umts_gsm before:
Diagnosis > *#32489# > Back > Back (to Phone Control) > [7] Network Control > [4]Aquisition Order> [1]Automatic
Aparently its fine now, but needs more testing for final confirmation, would be nice if someone tries this as well.

Potential Fix
I had this issue too...
On my phone, this issue was caused by having a custom APN configured for my mobile operator.
Deleting the custom APN entry completely fixed this problem for me.

Wifi not working

Creating a new topic, because the other one is tagged as solved, but it doesnt solve my problem however.
So my wifi is not working, it's connecting to any wifi hotspot but not sending data thru that, which ends in failing loading any pages on IE, cannot download any apps from market and so on...
Anyway this is what I tried so far:
1. Flashed to stock rogers (also tried different Tango roms)
2. Did hard reset procedure via hardware keys (Format all Yes)
3. Did hard reset procedure via About menu
4. Did hard reset procedure via Samsung Diagnosis code sequence
5. Logged to my wifi network, everything looks fine at this point.
6. Opened IE and entered google.com:
"We're having trouble connecting to this webpage" (sometimes no error message but white page with scrolling bars appearing on touch)
7. Tried to access my wifi router via IP address (192.168.1.1) - the same results like above
8. Tried to ping my Samsung Fous IP (192.168.1.18) from my PC with success
9. Disabled wifi network security on home wifi router, the Focus still not working
Additionaly tried a method that fix issues with wifi after using latest wp7 tools, but it didnt help at all.
When using my providers APN there is no problem with opening pages on IE etc., but it's not Wifi.... Internet is also working if I have USB cable plugged in, but again it's not wifi.
Cannot use warranty, the phone is from the USA and I'm in Europe... without any warranty service.
What else I can do, maybe there are some diagnosis codes that can actually help with real diagnosis on what happened with wifi on my phone?

Hello again (from the other thread). For completeness, add the following:
- current OS version
- did/not use WindowBreak
- when did the problem start (if you can identify an event and OS version/revision) - or you noticed
There might be a test for wireless in the "diagnosis codes"... Good luck!

After you use the diagnosis fix, it might take some time, mine didn't work immediately but after some time, it detected my home network. But it seems you are able to connect but internet does not work, this is certainly issue with router/DNS settings in your phone, because I have faced these problems in iPhone, it might wrongly mapped to unreachable ip, but never faced this issue in Windows Phone, you might try changing the default gateway/dns settings, you should also reset your modem/router, and try basic setup before WPA/WPA2 setup

Hi there
Currently using 7.10.8773.98, (MAGLDR 2.0) but tried different versions, even vanilla pre-mango ones, they didnt work well with wifi on my phone either. I checked it at friends home wifi, which is totaly different network and routers.
I never used WindowBreak, never had to because my phone was already unlocked long time ago with ChevronWP7 application.
Noticed the problem about 2 weeks ago, but I didnt use wifi too much, so it could started much earlier. Last installed application was WP7 Tools 0.8 alpha, and all I did back then was using some built-in tweaks (3G?) if there is any, cant remember to be honest but for sure I wasnt editing registry or anything like that, I just play some games from time to time, cant event tell why I installed it, maybe because I noticed there is a new version. I cant tell because I never paid attention to it especially with rare wifi usage at a time.

I have isolated the problem I guess, and it's not the phone's fault. Something wrong with the main access point (Mikrotik) at my place. This is weird because everything is working just not on Samsung Focus. I digged thru many options and couldnt find anything that blocked or stuff like that. Well took it to totaly different place and another wifi network, and guess what - it's connecting to wifi with data flow...
Anyway consider this topic as solved.

Wi-fi not working when phone goes to sleep

My galaxy S4 connects to any network flawlessly and I can browse the web, etc. but when I press the power button to lock the phone or if the phone goes to sleep by itself, when I unlock the phone, I'm still connected to the wireless network, but I can't browse the web or do anything. I have to disconnect and reconnect for it to do anything (and sometimes it takes 5 mins. to find the network. it says it's not in range 90% of the time). I've set wi-fi to "always on" during sleep and I've also turned wi-fi power saving mode off in the hidden menu but it still doesn't work. Like I said, it doesn't disconnect but the orange down arrow flashes and I can't browse the web, etc. I actually wiped the phone and the problem went away for a few days but cropped back up yesterday which leads me to believe there must be some bug causing it but I have no idea what triggers it. Does anyone have any ideas on what to do?

Are you running stock rom?

Sounds like what I'm experiencing as well!
http://forum.xda-developers.com/showthread.php?t=2303379
Hey guys,
Just noticed something odd this last few days. The statusbar WiFi icon is dimmed; but I'm connected on WiFi just fine. I can browse, and the WiFi settings is showing all is OK. As in, I'm still connected to my SSID.
Anyone experienced this? What's the best way for me to pull logs? I'm a bit of an Android n00b.
The particular SSID is on a 5GHz AC channel (pretty sure it's on AC, or at the very least N), on TKIP+AES. I've read that the S4 had problems with D-Link routers on TKIP+AES, but I've got an ASUS running DD-WRT. I don't have any other problem with the other devices in the house on WiFi.
Running WanamLite ROM, with FauxKernel 3.
Thanks!

I should clarify,
I'm connected to my router/SSID; but I can't connect to the internet.
But I'm trying out this new solution people have been suggesting.
I created a guest SSID on my router (ASUS RT-AC66U, on ASUS-Merlin firmware), and I pretty much disabled Intranet access on the guest account, and dropped TKIP.
Let's see if the problem will go away.

Unfortunately there's no option for me to create a guest SSID on my netgear router...

i believe this was/is a bug for the SIII. a quick search should bring you to a thread i was flipping through earlier for my girlfriends S3. I noticed it the first day I had my S4 but havent seen it happen since.

Go to your Wi-Fi, press the menu button and click advanced settings, there should be a option to "Keep Wi-Fi on during Sleep" if you want it on select always

The two solutions provided for that bug are to set Wi-Fi to always on during sleep and to turn off the wireless power saving mode in the hidden menu (which can only be accessed by dialing a certain number). Neither of those solutions work.

No go, problem is still very much there for me.
So far I've:
1) Created a guest SSID, with only AES. Problem is still there
2) Loaded a different kernel (albeit a 9505 kernel). Problem is still there.
I'm rooted, running a different kernel and ROM than stock. I'm on Virgin Mobile i337M (Canadian S4). I've unlocked my phone through the Service Menu, I've also enabled my AWS bands, using the QTPS patch. Though I think this is all irrelevant, because theloneranger08 is running an unrooted phone.
So something must've cause the WiFi sleep issue.
EDIT:
What's the best way to go about logging the issue here? I'm a total Logcat newbie. I managed to set it up on my Mac; but not sure what sort of logging I should be doing. Cheers!

Yeah I can't seem to get it fixed. I actually decided to call AT&T and they are sending me a new phone along with the necessary supplies to send my current one back. Hopefully it's a hardware issue and the new phone is fine. Although the fact that it worked for two weeks with no problems and wiping it got rid of the problem for a couple days leads me to believe it must be some bug in the software. Granted, I haven't come across hardly anyone (besides the people on this thread) with this issue so hopefully it is hardware related. I'll be so ticked if the new phone does the same thing...

I got a new phone and I didn't have any issues for a few days but now it's back. Anyone have any ideas?

Kinda impossible for two phones to have the same exact issue. Which lead me to believe this is a software bug.
Can you verify if you have "Check for Internet service" enabled, on Advance WiFi settings (Settings > WiFi > (tap menu) > Advance).
I restored my phone a few days ago, wiped it clean. I decided not to use this feature (it's off by default; but I had it on when I first encountered this issue), and I have yet to see the problem we had. I spoke to a friend who's a network engineer, it could be due to timeouts to the cell towers, whilst checking internet connection periodically, etc. etc.

No it's turned off. I've tried everything but I just can't find a fix. Is there anyway to somehow log the phone and see what runs when I put the phone to sleep? Is it possible that it's an app doing it?

If you're still having this issue, can you check into your Accounts setting? See if there's any sync error.
I had no problem for a few weeks after restoring my phone to factory setting. Then two days ago, the issue re-appear. The last thing I did was adding a new Google account (secondary account, for work). That's when the WiFi problem started appearing again. Then I noticed the sync issue on the newly added account, I had to uncheck certain options, and check them back again. Since then, the issue hasn't re-appear *crossing my fingers*
Way back in the day, I remember that WiFi indicators would look different if you have WiFi with internet access, but not connected to Google accounts (or have issues).
I know this is different than what we initially talked about; but I guess we're eliminating possibilities.

I do not have the issue, but maybe you can try this.
1. Open phone dialer (Phone App)
2. Dial *#0011#
3. The ServiceMode screen will be open. When it is open. Tap on menu button on top right.
4. Select "WiFi"
5. Find "WiFi Power Save Mode"
6. Press the "ON" button to turn the "WiFi Power Save Mode" off. (It will show as "OFF" if it is off)
7. Your WiFi will be off and on again.
8. Try to reconnect to the Wifi.

Ok i just found out its only doing it at home, i tried wifi and my work and it works perfectly doesnt disconnect and connect, but at home it does, though it never did it before and i didnt change or do anything to my router or my phone which i find very strange.
thanks for the help guys i appreciate it a lot, does anyone know what i can do?

have you found a fix to this yet? I'm having the same issue and getting ready to just return the phone and buy something else. My home network is fine, the other tablets, phones, laptops are having 0 issues, Yet my GS5 is either dropping or something, it seems to run horrible slow and things just time out.

No, and the reason that we don't know is that you didn't provide any useful details about your situation.
If you think that someone can do more than make a random guess implies that you think that there are only one or two possible causes. But most issues, including this one, have hundreds of possible causes. So random guesses are not terribly useful. Nor are we psychic, so the only way to efficiently narrow it down is to look for anomolies in your configuration. Which you haven't described.
You should be providing as much technical detail as possible, e.g. what is your home router model & it's firmware version and configuration details, phone firmware version, any specific error messages, any observed pattern, a logcat if you can and anything else that seems relevant.

Have you tried changing the channel on your router?
Sent from my Nexus 7 using Tapatalk

Change the router channel
Change the router SSID
Default the router comfiguration
Change the router operating mode
Update the router firmware
Move the router to a different location
Use a different router
Unplug your neighbours new 50,000 watt pirate radio station
Update your phone firmware
Buy a different phone
Sacrifice a piece of triple chocolate gnocche cake to the pagan God of chocolate and wifi
All random guesses with roughly equivalent (and small) chances of success.
Or one could try troubleshooting the issue methodically.

Hey guys,
I had this problem before, This is an issue with your samsung device and your ISP. They aren't compatible with each other.
Solution:
You must just block clients3.google.com in your modem/router. You can use Block Web Sites section in your modem/router.
Every thing has a solution.
Enjoy your device WIFI.

I have teh same issue on my S5 Cricket. The WIFI does NOT disconnect. Its connected however I don't have internet connection. Turning the WIFI on and OFF fixes the issue, for a short while until it happens again in an hour. Sometimes I slick on a link and wait and wait just to find out the darn WIFI is not connected to the internet. (probably not even connected to my router properly eg, I cant see my laptop shared drives for example).
This has something to do with saving battery or somthing. WIFI internals shut down, even though the icon on top of the screen still shows I'm connected.

Your phone thinks that your WiFi is unstable and dumps the connection to go back to 4g. Why exactly, who knows, but it's easy to turn off the "smart" network switch. Simply hold down the WiFi icon for 2 seconds to get into the connections section. Right there at the top is the smart network switch section ... just uncheck the selection box. Easy.
Lastly, people like fffft need to get over themselves. The fix for the original poster's question was easy, but since fffft didn't know it, he decided to instead attack in order to make himself feel superior. How sad and pathetic does someone have to be to troll forums looking for opportunities to attack and belittle someone else?

The issue is resolved simply by going to the advanced settings in Wifi and disabling 'Always allow scanning'.

Well I know that Smart Network is turning off wifi.. problem is that i have a fiber at home!! So what kind of problem smart network finds on my broadband?? ?

solution to wifi disconnect problem
I was looking for an answer to a different wi-fi question when I saw this.
I'm on AT&T with my S5.
Under the Wi-Fi settings I have an option for "Smart Network Switch" which says it Automatically switches between Wi-Fi and mobile networks to maintain a stable internet connection. Anytime a computer says it automatically does something for me; I typically say no thanks. I don't typically like my devices making assumptions of what I like, don't like or want to do. So I have that option unchecked. I never have an issue with the network stability once I've connected to a specific wi-fi connection.
Not sure if that will help you all or not. But thought I'd share.
so under Settings --> Quick Settings --> Wi-Fi you will find a check box option named "Smart network switch", untick it, this should take care of the problem.

Same problem
Hi, I have the same problem. Here some info:
- Device: Samsung Galaxy S5 (SM-G900F), Stock, not rooted
- Android version: 5.0
- Kernel version: 3.4.0-5640614 (2015-09-01)
- 'Smart network switch' is turned off
- 'Always allow scanning' is disabled
The problem started 2-3 days ago. When I turn on WiFi/WLAN the phone constantly turns it back off and on again. Didn't happen before, didn't change anything on the router (I have no access to it ) and didn't install a new app (as far as I can remember). I don't know if it only happens on this access point.
I made a log file (adb logcat) but am not sure if it contains sensitive information, is it save to share online?

The logcat doesn't contain any sensitive passwords.

I'm have the exact same problem.
Samsung Galaxy S5 (SM-G900T)
CyanogenMod (13.0-20151203)
Android 6.0 (Marshmallow)
Baseband (G900TUVU1ANE6)
Smart network switch: disabled
Always allow scanning: disabled
What's happening is as soon as my Wi-Fi finishes authenticating and connects, it is immediately disconnected and tries again. No other devices in my house are having any issues, so that eliminates the router. When I factory reset my phone the Wi-Fi begins to work again, so that eliminates my phones hardware. The confusing part is that I installed a bunch of apps such as AdGuard that could possibly cause an issue but everything worked and this started out of nowhere. Also, I factory reset my phone AGAIN and AGAIN, everything worked and out of nowhere while I was looking at my screen while idling, I watched as the Wi-Fi connection dropped and began the disconnect/reconnect loop...
I'm assuming it has to be a software issue because it only started when I updated to a newer Cyanogen. I'm about to test if other Wi-Fi networks have this problem and I'm also going to look through and post a log.
If anyone has any questions or suggestions that may lead to a fix, PLEASE help!
Thanks

Well I factory reset again, this time wiping the internal storage and everything is now fine. I did look at my logcat and there were Wi-Fi errors but I forgot to post them...

5Ghz Wifi help.

Ok, so I have a us997 LG G6, and it refuses to connect to my home 5ghz wifi (NETWORK_SELECTION_DISABLED_ASSOCIATION_REJECTION=1), its done this on nougat and oreo, i figured it was something wrong with the wi-fi radio/chip, whatever, but today I looked into it more, get ready, because hopefully someone can explain this on to me...
1. If I try and connect to my home's 5GHz wifi it has the error "NETWORK_SELECTION_DISABLED_ASSOCIATION_REJECTION=1" then the network disappears completely. (Wi-Fi analyzer shows nothing on 5GHz)
2. (at this point i tried to see if it was all 5GHz networks or just my router, so i started a hotspot from another android phone (Galaxy s5) and connected to it, and BOOM, connects right away (5GHz, channel 149, 'Very good' signal strength (makes sense, the devices are within a foot of each other), ok.
3. So I set my router to channel 149 and connect to it, it connects but has very poor signal strength, despite being no more than 3 feet from the router... honestly, i'm lost now, so I figure ok...
4. I turn off the hotspot on the s5... and IT DISCONNECTS (from the home network), and then the home network disappears... honestly, what... so now i am completely lost, I just want my 5GHz wifi. please help XD
(any other device i try connects completely fine to my home network...)
(AND on top of this all, I can make a hotspot on the G6 on 5GHz and it works just fine, devices connect with proper speed and 5GHz band!)
edit: If i am connected to ANY wifi network (5GHz or not) the 5GHz home networks shows up, but it still cant connect, when i disconnect from all networks, it disappears again)
TEMPORARY SOLUTION:
Disable WiFi
Go to the service menu (us997: *#546368#*997#) (h870: *#546368#*870), goto field test > WiFi test > select 'core both'. Press start
Go to the root of the service menu again, goto FTM test > select 5.0GHz, press start, you should see a 'Start Successful' message.
Exist the service menu enable and disable WiFi a few times, and that should fix it... Thanks to: cabal06ba for solution!

I don't know the details but when I unboxed and rebooted G6 for the first time, it didn't catch the 5 GHz signals either. I've searched some and found out that this was a common issue. Some people said "restoring the phone to the factory defaults" solves the problem. I've immediately done a restore process and 5 GHz is working like a charm now.

I've reset my phone a bunch of times between updates and rooting mishaps, and nothing (not in the mood to do it again), i will try resetting network settings.
edit: resetting network settings didn't do anything...

Network Settings Reset didn't do the trick for me either but with help of your first post edit I've found a fix (long-term functionality not yet approved):
1) Go to phone and dial *#546368#*870# to enter the hidden menu
2) Go to field test > wifi test > OTA
In my case it was disabled and enabling solved the problem! (actually I don't even have a clue what this setting is exactly for, found out through trial and error)
3) Then went one step back, entered FTM test, set 5GHz, started and boom, "start successful"! (before it had failed)
4) Finally I went back to regular WiFi-Menu, was switched off so had to turn it back on, no networks, off an on again, 5Ghz was back and still is after several reboots + resetting network settings once again to double check.
Hope that works for others as well!

Don't have an WiFi hotspots that are 5ghz near me now, I will test later, but I have tried using the WiFi test to enable 5ghz before and it didn't work
Edit: Well it said start successful, so hopefully it worked (BTW if you are on a us997 device replace the 870 code in the number with 997)
Edit 2: Devcheck reports '5Ghz support: yes', previously it reported no. Thanks!
Edit 3: Still does not stay after disabling WiFi
Also Even after a factory reset, still stuck on 2.4G

Without a registered SIM card, wifi works at the lowest common denominator on the G6: 2,4ghz channels up to 11 and 5ghz 36 to 48.
So where mobile signals are too weak, wifi is also limited.

I have a registered SIM, I'm on Verizon, Mobile signal is weak everywhere but standing outside a tower because its Verizon...

Once the phone had been registered with the provider, wifi is fully supported even w/o mobile network. Provided the SIM stays in and you don't perform a factory reset.
I had to get a nano sim in order to use my G6. It "unlocked" my G6's wifi, but i continued to use my trusty S5 for a while, so the G6 reverted to bad habits.
Part of the G6's antennae are in the metal frame, but i don't know which ones. These work best while kepping gripped, with no insulating case. While not bridging them all electrically with your hand, which is no good.
The first device with frame antennae, the Iphone 4 had to be modified for this reason. The first batch required the use of a rubber case or frame.

In my case, 5GHz did not work as long as the bootloader was unlocked. Even after I reinstalled the original OS via LG Bridge / Repair. Once I re-locked the Bootloader again, the LG6 connected to 5GHz.

I hope there is a way around this. Probably this behaviour don't apply to custom roms.

I'm still having the same issues, doesn't matter if it's stock ROM or custom , really don't want to relock my bootloader.
