Hi, is anyone has the same problem? When I'm connected at home to my Tenda router (WIFI b/g/n) after cca 30 min. my phone WIFI stops sending and recieving data, Skype is offline, etc... but WIFI in phone is stil switched on. After I switch WIFI off and back on (on my Samsung, not on my router), everything works good for a while and after cca 30 min. is situation the same. Is there in Samsung any WIFI sleep mode or something like that? Or some settings, which is not visible? Any other suggestions? Sorry for my poor English. Thanx in advance.
I'm having the same problem. But I did a factory reset and it works fine afterward.
And just few hours ago, I encountered this problem again. What did to get this error was, I pressed "on samsungapps" and it failed to update and thus results wifi connection stopping. What about you? Also my Kies air is not working.
are you guys sure you have wifi sleep policy set correctly? just to be sure, settings, wireless, wifi, menu button, advanced, wifi sleep policy to NEVER.
Yes. And also even if i manually disconnect and reconnect the wifi back. The data still doesn't come in. It is stated there as connected but no data at all.
Somehow Wifi keeps searching every few seconds, even thought it's connected.
This is bound to cost in battery life too.
I have reseted router to default settings, disabled n mode, disabled security (only mac filtering is on), disabled all unnecessary features and PROBLEM IS SOLVED !!! Thanx God Tomorrow I will experiment with router settings to know, what was causing this error ;-)
Well at least u're connected, I'm facing the same problem as the thread starter. No data flow at all. Browser showing me offline msg. I had the same problem on the 1st day with the phone after I woke up. previously playing with most of the default aps. So i'm not sure what went wrong, did a factory reset and it works fine.
Until, few hours ago, I tried my kies air which didn't work. Browser couldnt load the address given. And I thought i had an outdated kies air, so i went to click on samsungapps, which failed to update me. At that point the wifi is still working, i leave my phone for about 30 mins, and when i came back. The same problem which happened on the 1st day came back. I was hoping to find an answer here so I didnt do the factory reset it. On another note, the phone wifi works after restart, but wouldn't last.
Edit: The wifi works after i resetted my modem to default. oh well. at least that solved it.

Hi,
Did you find out what setting was causing the connection issue? I also have this problem with my Tenda router. I thought it might be the wireless N, but disabling that doesn't fix it. I have a wireless distribution system set up with other tenda routers so didn't want to disable all the settings to troubleshoot if i can help it!
Thanks

I have the same problem, my router is N and the conection between SGS2 and my router is bad. Any idea?
Same problem here, I'm running WZR-AGL300NH in access point connected to my Ubuntu Server. Everything else works in the house just fine but SG2 stops transmitting data after a while.
I recently upgraded to KF1 firmware (and unknowingly wiped out whole phone, being on the bleeding edge and that didn't seem to help.
I would very much appreciate all tips because this problem is very annoying!
Additional Info:
- Buffalo is running latest firmware
- Authentication WPA2-PSK
- Encryption AES

Same symptoms here. Cisco DDR2200. WPA2 PSK. Haven't tried fiddling with the router yet.
This seems to be a common problem. Anyone knows of a definitive fix?
Bump...I have the same problem and the issue persists even after i reset the phone
Sent from my GT-I9100 using XDA App
Glad I found this, thought it was the ROM I had flashed to the phone (which is VillainROM)
I keep losing connection from my phone via wifi like everyone else in this thread
edit: I've just assigned my phone an IP address via my routers settings and I can connect to the net again
Also when it wasn't working, I couldn't ping the phone. When I assigned the IP just now I still couldn't ping it.
When I did a tracert to it, I could get to it when the IP was assigned and when it wasn't.
I have no removed the assigned IP for the phone from the router. Wifi connection is still working after disconnecting/reconnecting wifi on the phone.
I can also now ping the phone, where as before it was getting timeouts.
Also when it wasn't working the first time when I did a tracert it was showing up as HPsomething (didn't make note of the numbers)
this time when it is working it's just showing up as the IP address when doing a tracert.
Another update:
Just checked my printer, it has an IP address manually set on it, which at one stage when the phone wasn't working for internet it had the same IP as the printer, hence when tracert'ing it I was going to the printer instead of the phone and getting the HP etc back.
When it wasn't working at that time and looking at my routers DHCP list, it had the MAC Address of the phone against the IP that the printer has....
So I've got some issues with how my own network is setup ^_^ which looks like is causing me grief.
So the issue is with DHCP? Setting a static IP fixes it? I'll have to try, but I doubt this is a problem with the network, as all my other devices use DHCP without this problem.
I have the exact same problem!!
It's really annoying.
i was having problems with wifi too.. it keeps scanning and checking, etc, signal dropping for no reason..
fixed mine..well for me it worked
backup ur phone ( i dont take responsibility if ur phone catches fire or dies or chases u around )
u need to be rooted
download FXR WiFi fix and rescue from market
and just run the app.
now my wifi signal stays constant speed and i get good speeds
alternatively try
WiFi Fixer
both of them will cause high battery usage..i think since it keeps the signal at maximum.. so only enable wireless when i need it or use juice defender or green power.
greenpower seems great. using this at the moment
Hello - Have been running XtreStoLite rooted for months now on my SM-G900T. About a week ago all of my known Wi-Fi connections would stop working sporadically. When I take a look at whats going on, my phone says there is authentication issue (password is wrong). It would seem obvious that this is the problem but I know this is not the case when connected to the few Wifi networks I consistently use, because I would have to be the one that would change the Wifi password to connect (I haven't changed it). Also, it may work normally anywhere between a few seconds to a few hours, then bam, out of nowhere I'm disconnected due to authentication problems. Where I'm at now is that there is something wrong with my S5, causing it to send the wrong password credentials. Even if I forget the connection and re-enter credentials it will fail, no other devices have this problem on these Wifi networks. Does anyone have an idea where to start troubleshooting now?
Hello, for quite some time I have problem with connecting WiFi to my Android TV. I tried everything, from Android reset, router reset, changing password, WiFi name, changing from DHCP to static IP, installing WiFi apps like Avast WiFi manager and nothing helped. The exact problem is that WiFi is disconnecting only when I open any app. For example, I connect WiFi normally and I check connection on router and router see that Android is connected so everything should be ok. But when I open YouTube, main page is just loading and at one point it says there is no connection, after leaving app WiFi icon that is showing signal strenght shows very low signal, only one dot. After turning WiFi off and on everything is normal again until I open an app. About notifications I am receiving them so that means that TV is successfully connected to internet until I open an app. This is weirdest problem I ever had since I am using Android devices and Internet. My TV have MBX S812 with B.S805 chipset. It have 1GB RAM/8GB ROM with Mali 450 card. Android version is 4.4.2 with kernel version 3.10.33. About recovery mode this Android box don't have it at all. There is reset button but it's not opening recovery mode it just resets Android. Android is not rooted. After reseting Android I can't even sign in to Google Account because when he tries to use WiFi to sign in it say there is no connection. I really don't know what else I can do now. I hope I provided enough info. Sorry for long text and thanks in advance!
I have an LG G4 running stock Android 6. Been using the stock email client for years to connect to a google hosted email account, via their imap servers.
All of a sudden I get intermittent connectivity to imap.gmail.com over my wifi connection. The message 'The server is unavailable. Please try again" comes up all the time. If I turn on the Private Internet Access VPN the phoen connects fine, if I turn on cellular data - it connects fine.
I ran a trace route on the phone to imap.gmail.com and it gave me one hop which resolved to a Verizon host.
My desktop connects to the same servers and have not had email issues with it, seems isolated to the phone. So my thought is that there is not anything wrong with my local network here. The rest of the apps seem to work ok on the phone, so it doesn't seem to be a global wifi issue.
Any thoughts on further testing or ideas on what to try?
Some more diagnosis steps.
I installed K9 mail and it works fine.
I tried the native mail client app on another wifi connection without VPN and it worked.
I changed from imap.gmail.com to imap.googlemail.com and get the same result.
I am running out of ideas on things to check, beginning to think that I need to do another factory reset and see if that fixes the problem. Unless there is someway to adjust server timeout settings on the native client.

So I can't seem to find a straight answer on this because most of the results that come up in searching have to do with geolocking due to using VPNs with foreign endpoints, and that is not the issue here. I have a VPN server at home, and I keep my phone connected to it at all times to funnel traffic through my pi-hole (phone is not rooted, so no other reliable adblocker can be installed). Play store refuses to download or update anything unless I disconnect the VPN. I originally thought it was the pi-hole itself breaking something, but if I connect to home wifi (runs through the same pi-hole) it works just fine (no it is not set to wifi only). If I just disconnect the VPN, it works fine over LTE. I have true unlimited, and rarely use wifi, so I never turn it on. I tried IFTTT to turn it on only at home but it never works right.. More often than not, it doesn't turn it off when I leave - which causes it to try to connect to random saved hotspots as I drive through town, or the one at work which has crappy coverage, which interrupts my streaming radio.
Is there some hidden setting or tweak I can do to make it work properly and do automatic updates? As I said, the VPN is connected at all times, and I don't remember to check for updates regularly, so it is not uncommon to find dozens of apps that haven't installed updates in a month or more. I DO get notifications of OTA FW updates from the carrier each month or so.
It's a SM-G965U1 (CSpire model on a local mom and pop carrier) if it matters,
