Hello everyone,
Last week I upgraded my S4 to a brand new S5 on T-Mobile and currently it's stock and unrooted. It works great, except it won't automatically connect to WiFi. Every time I encounter a known WiFi it'll say Sign in Required. I'll press Connect and it'll then connect and function perfectly.
This smells like a software bug to me, but then I'd expect more posts on this topic (I didn't see any posts on XDA, and posts elsewhere were unhelpful).
What I'd ultimately like to know is if this is a hardware defect and I should get my phone replaced before it's too late, or if this is something that a software update (or rooting and flashing) will fix. Or of course it could be neither...
Thanks!
I have the same probblem and I am dying for a solution. I've spent hours googling and testing different things to no avail.
I am going to try to bring as much detail as I can, hopefully someone can pitch in.
Things I have read might work:
"forgetting" the connection and recreating it
Turning off and turning back on
Turning off, removing the battery
Turning off, removing the battery and the sim and waiting a minute (seems like voodoo to me)
Factory reset
I've tried everything, bar the factory reset which I am reluctant to do, specially when people's answers on forums said it wasn't a solution.
To try and shed more light, I would also add that:
It does this with any network (so it's not channel/router issue)
It does this consistently (and since I got my phone)
It finds networks, but just won't connect
It always connects fine if I pick the network (so it's not a distance/bad reception issue)
My phone is unrooted and stock and I have no weird apps (only popular/regular ones, social media, news, and so on)
My options are set correctly (notifications for open networks is checked and wifi is on)
I really hope someone can help as I rely on wifi a lot, and this is kind of a deal-breaker for me.
So I found a psuedo-fix here: http://forum.xda-developers.com/showthread.php?t=2723486
The key part being:
1. >Wifi >Advanced >Disable (uncheck) Smart network switch.
2. Forget connection, then establish connection again. Works no issues.

This has "fixed" it for me, but it also means I no longer have Smart Network Switch which is kinda annoying, albeit less annoying.
A true solution would be lovely.

Tried, didn't work for me.
I now have factory reset and let google reinstall all my apps.
Until now, auto-connect works.
The only thing I didn't do this time that I did last time is deactivate a bunch of samsung apps that come pre-installed.

I have been having the same issue. I can't get any answers either. It really is frustrating. I am going to keep trying to find out. When I called the T-Mobile store they said that I could bring it back w/in the 14 days & replace it and I may do that if I can't get an answer for the problem! If you happen to find out what the answer is PLEASE post and let us know! Thanks
My wife has the same issue with not auto connecting. She has a AT&T S5 that is not rooted....thanks to AT&T putting her in prison lockdown. I think it could be something with the last update because her phone used to auto connect just fine and now it doesn't. The strange thing is that she just now noticed it not connecting and she had took an update that was a few weeks ago or whenever it actually was and now we don't really know for sure if it's really just now an issue or has been since the update....imo I think it could be something with the update.
I have an S5 as well with no issues, but then again, I have the TMO that's rooted and carrier unlocked running custom rom.....thanks TMO for not being D***'s like at&t
Solution!
Long story short, there's a problem with Android and DHCP. Specifically, an IP associated with a router doesn't die when it should and attempting another connection goes back to this IP instead of using the correct (new) IP.
The good news is to forget the problematic wifi connection, head into /data/misc/dhcp/ and remove the files, reboot then connect to wifi. That flushes the DHCP lease information and life should be good.

use a program like "root explorer" or "ES file explorer" and navigate to your root folder ( / )
then follow the path /data/misc/dhcp/ , you will find the files i mentioned there.

Im reviving this thread, I have this issue also. And with my "unlimited" tmobile bandwidth of 2gb, this bug is completely screwing me over.
I quoted this post since you just claim its Android and DHCP, if thats the case, wouldnt all android phones just not work like the S5?

Hey I'm having the same issue, only with my work open wifi. The phone will be aware there is a wifi and it tells me to sign in. I go to the wifi settings and tell it to connect it does, but if it drops for any reason it won't automatically connect again, I have to go through the same thing every time.
I read this in a previous post:
"use a program like "root explorer" or "ES file explorer" and navigate to your root folder ( / )
then follow the path /data/misc/dhcp/ , you will find the files i mentioned there."
I have X-plore and went to the root/data folder, but there was nothing in the data folder - Do you have to be rooted for this to work?
Any help would be appreciated.

It works fine on my home network and others that I have a username and password for. The issue is WIFI hotspots at coffee shops and work and such, where I don't have access to the router settings.
I have an app that does an auto login when it recognizes that you need to sign in once it connects to wifi, and it works when I tell the phone to connect, but the phone will never connect automatically - I have to go into the WIFI settings and tell it to connect manually every time.
I have the 'Smart Network Switch" unchecked, and I have 'forgotten' and reconnected several times but it still happens.

Thanks. This solved my problem ?
I had a corrupt .keystore on my S5 and the fix I found by googling was to do a reset of the device.

Lately I have been reading many post related to Wifi problems in the HD. I had the same. Even I was very near my router I couldn't connect to the net and the signal was very weak.
So I entered my router configuration and I found a solution.
Before, for security options I had: WPA-PSK [TKIP] then I changed to WPA2-PSK [AES] (of course you also have to change your HD connection configuratoin), and now it works great¡¡¡¡
Now I have all the bars for the signal and I can connect very easily.
Hope it works for other people
I have a similar WiFi connectivity problem, but after reading of the poor service provided by most vendors and HTC itself, I will try to gather some more experience with the problem before I contact HTC or my vendor, and hopefully find a solution. Bellow is my experience so far:
I own an HTC Touch HD since January and have a similar problem, only it surfaced last week. Before I had only used the WiFi connectivity briefly. The problems started after I installed an AP on my house expressively for the new PDA. The node is fully open and set to B/G/N protocols.
After a couple days of medium (couple hours per day) use the WiFi connection suddenly quit, the device would try to connect (the top bar showing the WiFi connection animation continuously) and after a few moments gave up with a dialog box stating the current network settings were wrong (even thou they worked fine a few hours earlier).
I tried several hot and cold resets, but only solved the problem after flashing a new ROM; even then the same symptoms reappeared after a couple of days of regular use. Again no re-setting would cure the problem, and now not even flashing the ROM again would work. Nonetheless, some hours latter the WiFi would connect perfectly with the same nodes it refused to before, and in very short time.
I have witnessed this cycle twice and have yet not been able to find a trigger for it, but will keep my eyes open for any tell tale signs, and post any findings here.
I could add to the above mentioned problems.
i got a new hd just few days back.
The wifi worked great. But now it doesnt.
I have disabled wifi, so can start it whenever i require.
I click on wifi button to enable it.
Then open opera, try any website.
it will open fine.
For instance say my email at gmail.com
Now after that if i try to open anysites or even continue with my mail, it shows error saying connection not available.
One of the workaround is to go back to toggele wifi off and switched it on.
Not sure if anyone faces a similar issue.
I's been about a week since my last post and I have already witnessed a couple of cycles of WiFi connecting perfectly and then not connecting at all.
No matter the settings I try after it decides not to connect, it won't. Even to nodes it had connected perfectly and fast jus minutes before.
I thought re-flashing might help but so far has proven ineffective. Once I thought some part of the non-volitile memory was causing the problem since after I cleared the memory I could connect for a while.
Any thoughts anyone?
Same problems here.
For the last hour I have been reading 10ths of threads here concerning WiFi problems.
My HD's WiFi worked fine on my home and outside for about 2 months. Now it doesn't. It reports connection, but no program can use the internet. At best, it seems to be able to exchange some Kbytes the for just a few seconds after a connection is established. Then nothing. Connected but unusable.
Tried everything Internet/My Work/My ISP, WAP enabled/disabled, soft/hard reset, everything.
When connected through ActiveSync everything works fine, all programs see internet.
Has anybody taken their HD to the service? Has any HTC service worldwide identified the problem as hardware and solved it by replacing something?

I have just encountered a similar problem, but already used wpa/wpa2 with aes. Have tried a hard reset with no joy. My old HTC Touch has no probs connecting via wifi nor does my laptop so I would surmise that the prob is with the HD and not the router.
I am going to try flashing with the latest version of Duttys 6.1 rom and see what gives.
Edit: Tried flashing with new rom with no success. Take a look at this post.
http://forum.xda-developers.com/showpost.php?p=3769339&postcount=7
There are a couple of files to download but i only used the second ie this one.
http://forum.xda-developers.com/showpost.php?p=1363759&postcount=2
Now no problems and can connect via wifi no probs, ip address assigned by dhcp.
Try to go into WiFi settings and move the power slider to max performance. I need to do it here to access my router. This happened also with my HTC TyTN II, with any recent radio firmware. The original WM 6.0 ROM and it's radio work fine in low power mode, but the new ones appear connected but are always at 1 Mbps and there's no traffic until you move the slider to performance mode.
You go into WiFi settings and you configure manual IP and DNS so as router.
DNS is important.
Whit manual configuration, Wifi work always.
(sorry for my english)

This is not a solution. I didn 't buy the device to be able to connect to my home WiFi only. What about public hotspots? Or hotels? Or whatever outside your home?
Bought my Galaxy yesterday and it works fine but on one point. Yesterday I was able to find the home network of my friend in his house. I could connect to the internet with that as well as through 3g. But later at my place it does not work with any home network. When I try Settings, Wireless and network, Wi-Fi settings and Wi-Fi, the phone turns on Wi-Fi and scans for some seconds and the leaves a message that says "Unable to scan networks".
Maybe I have switched on or off something accidentally as I am a new user on this phone? Anyone for help?
turn off the phone
then turn it back on
in another words, reboot your phone, seems like it got stuck in some WiFi bug
It does not seem to help. I even took out the battery. Still unable to to scan
you can try this
*2767*3855# WARNING! FACTORY DATA WIPE AND RESET as soon as you enter the last # use it only if you want to clean wipe your phone

Maybe there is another way to set the scan possibility?

see the last secret code?
It defaults to User space. I do not yet have any extra Micro SD card. Is it that what means with User space?
Tried that last command and do have at least one file of each in the folders, but the phone answers for each of them that the files are not ready? What else is there to be done?
Had same problem, tried factory reset... didn't solve it. any ideas? it can't get an ip address and it used to work
probably the next best thing is to use Odin to reflash the modem file to the phone
or a full flash to the latest firmware
Same problem appeared on my SGS. Boy this sucks. The wifi became "hard" to connect sometimes. Or I could connect but had no internet access. Then I disconnect and connect several times to have net access.
One hour ago the wifi died. I turn it on it says "Unable to search for networks" and shuts itself off.
WTF. I have to reflash!!!! Not good. Also I don't know what caused this. I'm on JM2 with One Click Lag fix 2.1
one thing is for sure, the STOCK rom has no problem with that
so it is either a Router thing, or a firmware specific problem

JM2 isn't a final release firmware. Realistically, if you want everything (well, other than GPS) to "just work", stick to official firmware.
Well, I for one, have only the the official firmware and it is the latest one what I have learned. Still the phone behaves as in my original post after just a couple of hours. Is this and other peoples beautiful Samsung Galaxy model not tested enough by Samsung? Has anyone more information than we have?

Hi all! Thank you for your inputs to my problem. I have now got it working. For those who are interested how, I can tell you that I only did a simple Factory Reset command.
problem solved!
I had the same problem.
I was trying to configure a invisible ssid and by distraction I created a normal WPA 2 network, ending up with two networks with the same ssid (when I was turning off the wifi, it wouldn't go off at the first try, weird, )
Solution:
Edit the "/data/wifi/bcm_supp.conf" (with root permission) and eliminate the duplicated network, problem solved! At least in my case (no need for factory reset )
http://forum.xda-developers.com/showthread.php?t=757619
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.

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.

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.

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'.
Hope this helps.

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...
Hey guys,
for some week or maybe month, I'm having some kind of issue with my device and the home-wifi-router.
The problem: There are some kinds of webistes that just aren't working in my home wifi. I tried dozens of different browers all with the same result. Some pages that don't work are amazon.de obi.de and kicker.de and twitter.com
Same thing with the Amazon App and Twitter app. They just don't load any content - with mobile data on, it works out.
All of those pages and apps work out with other android devices and also in other peoples WiFi.
I also tried the secure mode, with the same result.
I've heard, that there might be an issue with ipv6, but, unfortunately I can't switch anything on or off in the router settings.
It's gotta be something about the router, but I can't change anything. Maybe there's a way to work around that with some kinde off app or something to turn Ipv6 off, IF that is the problem?
The phone has got stock rom, no root, no nothing. Maybe there is an opportunity with rooting? Warranty is expired, so there's nothing that speaks against rooting, if this might help. But then, I need someone to help me with all that - so far I only rooted an old nexus phone wia root toolkit.
Thanks!

I had exactly the same router. I hated it, my download stream was very slow that I was ready to throw it out of my window. Unfortunately it didn't happend.
Check your routers internet filter settings maybe something blocks your device . Also check your routers wifi settings if necessary turn it off and on again. Reboot your router or in worst case reset it BUT DON'T DO IT IF YOU DON'T HAVE THE ACCESS DATA.
Try to change the wifi settings on your device. Change from DHCP to static and see if it works.
Thanks for your reply.
I checked everything, but there is no filter setting. I restarted wifi and turned of the router several times.
Static IP also seems not to work, the issues remain.

There must be a filter setting. Check the internet tab of your router settings and you should find a filter option.
I looked it up, but there is just the daily reset rule but in the filter tab there is no active rule or something that can be unchecked.
You should ask your internet provider about this situation...
