Recently I have ran into weird problem. My internet was working fine until yesterdays afternoon. I had LTE on and suddenly it stopped loading anything. Browser didnt load any page, fb didnt refresh et cetera. I tried to reboot system over and over but it also didn't work. And magically suddenly it started to work again. At this time internet is working, but I am afraid it will stop in the most anticipated moment. All above also applies to any WiFi network. What can I do? I have flat S6 running XstreoLite, based on COI9 newest firmware (modem is also COI9).

hello guys,
i may have a problem with my wifi connection.
i bought two days ago the phone and yesterday i was playing with it in my house. i have some kind of problem when i am connected to my rooter.
when i connected my phone, i started viewing some sites and watching youtube videos.
suddenly i had this problem:
at the browser when i clicked a site, it started load it but never ended, just showing a white page. if i pressed stop and reload then the site was loaded ok.
this happened all the time.
when i returned to youtube the videos started and played for 10-20 seconds and then were freezed because the phone could not get the rest video.
at the same time i had internet access from my rooter as i could navigate at sites from my tablet.
if i close and open my wifi on phone then the connection was ok but after a while (10 mins) this strange behavior started again .
has anyone ever had the same problem;
thanks you
(PS sorry for my english)
What ROM are you using, and did you try to reset the phone and wipe cache/dalvik?
Sent from my HTC One XL using xda app-developers app
the phone is new (2 days old) and its stock
Have you tried simply power-cycling the router? Should be one of the first things you do, anytime you have a WiFi problem, as this will clear it up many times. I think I've seen this help even in cases where other devices work on the WiFi network properly.
yeap, i restarted both router and the phone
i have changed all the settings on the wifi-settings but did not see any progress.
From htc support told me to worj the phone in safe mode, but i have to wait until i return home
besides this problem, i cant connect and the router at my office (i had the same problem with mt s2 after an update, but 1-2 months later sammy rolloed out an update and the problem fixed)
Is security enabled on your WiFi network, and if so, what type (WEP, WPA, WPA2, etc.). You might try switching the encryption type (although WEP is not recommended, as its not very secure). I've seen cases where this has helped various connection problems.
I have had this problem with a lot of phones that friends and family bring by. 90% of the time the problem is a minor setting on the router. Some Android phones don't like AES encryption. If your encryption settings on your router are set to "AES" or "TKIP and AES" try changing it to just TKIP. You should see improvement with your connection.
You may have to change the security settings on other devices that are connected to that router as well to refelect the change.
hey guys,
yesterday evening, when i returned home i checked my router if it was able to change the frequency from 2.4GHz to 5GHz but i could not as at the channel it did not had choises for 5GHz.
i did not change the encryption type.
i restarted the phone, and entered in safe mode. after 10 mins the problem occurred again, i removed chrome, and suddenly the phone started working fine for until 1 hour and so i figured out that the problem was the app chrome, but i left the phone in safe mode and went to bed.
next morning (today) i started watch sites and after 5 minutes the problem occurred again. (i did not turn off the phone from the previous night, still worked in safe mode)
is there any possibility the problem to caused when the phone is in standby? although i have the wifi activation in option always
I got my daughter her tab 7.7 about 6 months ago & had been going on perfectly. Android version is 3.2 & I have no easy measures to update for the time being.
For internet connection she uses only my WiFi secure connection. It was working fine all this time.
Today she can't log to her Facebook account via the Facebook app. I checked it out to find that I can log in via the browser but not the app. I thought it may need updating and tried Google play store but I was astonished to find it not working too as it gives me "No Connection. Try again".
I noticed that the WiFi mark is white & not showing the green strength marks, but connection is confirmed by the WiFi name. I was shocked when I tried the software update from "about" when it gave me the "no connection message" despite working WiFi connection. Samsung app is working perfectly & I can update its applications.
Also funny thing happened, when I tried the browser it kept giving me certificate errors many times.
I tried the VPN as I googled around but nothing changed. Same problem.
Switching off & on didn't help either.
Any Clues??
Thanks
Most strange thing happened.
Everything is back to normal without me doing anything.
I left the tab for a while while writing the previous post.
When I came back I found the app update mark showing up, I turned on the WiFi & touched the update icon, the strength signal showed in the WiFi & update started the goggle app. All went normally. Facebook app worked & even the browser certificate errors disappeared. The software update in the "about" worked fine & checked & found no updates.
What is going on...
Can anyone explain to me what's happening?
Thanks

Try Power Cycling your modem/router. That often corrects connection issues. Presume other devices were connecting just fine?
Hi.
I only have one wifi network around atm. My N5 was working fine with it, and yesterday it started disconnecting from it.
Right now, when I try to connect, it connects for 3 or 4 seconds (it gets an IP address and actually connects to the Internet) before jumping back to data connection. When entering the Wireless menu on my phone it says "WiFi Connection Failure".
I thought I might have tweaked something I shouldn't (since also yesterday I installed Franco kernel and App Ops), so I went back to stock (using the Nexus Toolkit) and in the process I updated to the newest 5.1 release (I had LMY47D version and upgraded to LMY47I).
It didn't help. I also tried changing the router channel and security type to no avail.
Of course, I also tried to turn airplane mode on/off and forgetting network. And I just downgraded to LMY47D to see if that was the problem. But it didn't fix it.
I'm attaching the logcat. I hope I did it properly.
Any suggestions? Thanks!
UPDATE: I noticed it works in Safe Mode. I'll try to find which app is causing it.
I'm having exactly the same problem.
Updated to 5.1, after a run with Nike+ and Runkeeper, with GPS and Cellular Data on, battery drained and phone switched off. After a recharge, this problem emerged, different ROMs, different stock versions, different kernels. Nothing seems to make wi-fi work again.
Hello there, I have a weird issue with my android phone, suddenly when I try to connect to a specific network using Wifi my phone gets blocked (Black screen) and is totally unresponsive, the only way to get back the phone to work is doing a full factory reset, This happens since yesterday afternoon when I get back to the office and tried to get connected to my office network, everything was working fine with my phone, no new apps installed recently, am on KitKat 4.4.2 and as I told you everything was fine till yesterday. I try to connect to my home wifi network and to other places, even public networks, and it works fine without problem, it seems is just with my office network but the IT group told me no changes was made in the network configuration since past 2 week.
Any sugestion, troubleshooting tips???
Thanks a lot
Hi there,
Please give us more details about your device.
Thanks
I recently acquired a Permanently Unlocked US T-Mobile Galaxy s7 SM-G930T. Since I have Verizon, I flashed it to the latest Verizon Firmware SM-G930V from sammobile using the latest Odin. Everything went perfect.
The only problem is that the wifi will not stay connected.
It will connect for a few minutes at a time, and then, despite it saying it is still connected to wifi, videos will suddenly not load, apps will not open. I run a speed test and then it will show the little exclamation mark on my wifi signal, only then showing that wifi is not connect or having problems. It's very tedious as I go based off the wifi signal to and since it says it's connected i am missing important notifications despite my mobile data being connected. I have unlimited data with my carrier so i could simply stay connected to mobile data at all times, but i would like to have my wifi working again. Does anybody know what may be causing this problem.
I tried flashing it back to T-Mobile. and once again everything works perfect. except for the wifi. So i believe it may have to do with the firmware, or maybe i need another file or files that i still need to install? I have been researching it for a week and i just can not figure out a solution.
I tried resetting my router, nothing.
Different older firmwares for Verizon from Sammobile, nothing.
Resetting Cache in recovery mode, nothing.
Unchecking Smart switch (function for it to switch between mobile and wifi automatically), nothing.
Unchecked Wifi and bluetooth scanning, nothing.
Can somebody please help?
Just asking, what were the bootloader versions of the T-Mobile and Verizon ROM's you went back and forth with? *Bootloader version can be found in baseband number i.e SM-930TUVS4CRL1, The 4 is the BL.
