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 And I thought i had an outdated kies air, so i went to click on samsungapps, which failed to update me.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
Ever since I received my OPX I had little problems with my data, independently of using Wi-Fi or mobile internet (2g/3g).
It started with the fact that in the installation of the phone it couldn't connect to verify it's connection, although wifi was connected correctly.
I started it without the connection it wanted and factory resetted it and then I got the same problem, but after a few minutes it worked correctly and I could install my phone without any problems.
Now when I work with my phone (Whatsapp, 9gag, webrowsing, video streaming) it sometimes stops with loading, like it has lost its connection, but both Wi-Fi and mobile internet are connected.
This is very frustrating when watching video, since it just won't buffer anymore and I have to wait for like 1 minute before it continues and reloading the page helps most of the times, because I then force to get data.
Sometimes when WhatsApp isn't loading/ keeping it's connection I just start a SpeedTest to ensure it has an open connection. This works most of the times.
Also WhatsApp Web keeps losing its connection while the screen is on.
I hope you guys have some ideas on this subject.
I have a similar issue. In my case the device seems to have problems with certain WiFi-Networks (at university to be precise). The connection with the WiFi is still there, but there's no actual connection to the internet sometimes. That's why your mobile data doesn't activate - there are no connection issues on mobile data for me.
The cause for this is probably the lack of a 5GHz WiFi antenna. I don't know why, but my OPX cannot handle the 2.4GHz WiFi at university (at home it works fine!).
So to test this out, you should try different WiFi-Networks. If the network is 2.4GHz only, it should be working.
The WiFi thing while setting up the phone is a known OxygenOS bug and can be worked around.
Hi, I am using Redmi note 3 Kenzo runs on RR ROM Latest Version. In sometimes my device will not provide internet through wifi. It will shows that connected to a network but no internet connection. Same time if i connected to the same network by my other phone or with my Laptop, there is no problem. I can access the internet. After rebooting the phone (Note 3), It will work like normal. Plz help me to solve my problem.
The MIUI update has bugged the 2.4GHZ wifi; it will connect and work on 5GHz, but 2.4 tries to connect - connects and instantly disconnects, despite the wifi status saying it is connected and working.
I found this info under the phones advanced CIT testing menu.
It HAS been reported on the MIUI forums, so hopefully will get fixed soon, until then, I suggest you disable 2,4GHz, so you dont accidentally run up a huge 4G data bill like I have.
Hello. I've always had worse WiFi on my Lenovo A7000 but recently it started to be just terrible. I have specifically theese problems: The phone sometimes doesn't notice nearby networks while every other device with WiFi does (ussualy on weaker WiFis), When I try to connect to the WiFi it just doesn't do anything and ussualy the network disappears from WiFis list (I noticed that when my phone is locked it connects but right after I unlock it it disconnects), Sometimes when i try to load some webpage or video the phone disconnects from the network and sometimes the network disappears from Wifis list, When I'm connected to strong WiFi it works but it's very slow (it can't even load a webpage). Theese problems apply for every WiFi I have access to so the problem isn't in my wireless router or the other routers because other devices work fine. Does anyone know what can I do ?
Anyone else having problems reconnecting to a WiFi connection, or even seeing WiFi SSIDs after disconnecting from WiFi?
This happens to me intermittently. I have 5 WiFi SSIDs in my house. 2.4G and 5G from the FIOS router, and the same from a WiFi access point on another floor at the other end of the house, and a Guest network from the AP. I can normally see all of them from any point in the house, as well as half a dozen from nearby neighbors. And my s9+ normally connects, automatically, to my primary 5G connection without any problem.
But occasionally, after being out and coming back home, or after the phone has been asleep for a while, it won' see any SSIDs. Not mine, or the neighbors. I've tried scanning for WiFi networks, turning WiFi off, waiting a few, and turning it back on, but it doesn't see anything, and won't connect. I've even tried manually inputting the name of one of my access points, but the phone won't find it.
Turn on WiFi automatically is on, WiFi power saving mode is off (although I've had the same issue with it turned on), Keep WiFi on during sleep was set to While charging. I've changed it to always, but it will be a while to see if that helps.
The only way I've found to get it to see WiFi networks again is to reboot the phone.
Oh, and other devices, including other Android phones, see all the SSIDs without issue.
Any thoughts or ideas?
I have te same issue here, I can't find a fix.
Mine will not connect to mobile date after I turn my wifi off. I have to reboot the phone in order to be able to make a call or use data. It all seemed to happen when a pop up came on to enable wifi calling. I can't figure out how to turn that off.
I don't have acupp1's issue with mobile data, but I seem to have resolved the WiFi connection issue by not letting the phone turn WiFi off during sleep. Haven't had the problem since I changed that setting.
I got the same problem since I rooted
Been trying to figure out if its a VENDOR Firmware problem or what. I do know that every developer says its a bug with the s9 when rooting. I've personally watch the live log on TWRP when flashing and seen where it mounts the VENDOR Firmware and then unmounted at the end. So it could possibly be a problem between TWRP and the s9 ROMs idk know exactly yet but I'm looking for a solution also. But I'm going to try what you did with your WiFi then report back here.
