Weird wifi problem - Galaxy S 4 Mini Q&A, Help & Troubleshooting

Lately I've found that i have a problem connecting to apps (Snapchat & Instagram) via my home wifi . Thought it was the router but my brother has a S4 mini too and no problems. weird thing is browser works and wifi works perfectly in airplane mode and with no sim. could this be a carrier related issue or something in the settings ? Any help would be appreciated.

Try hard resetting your phone and if that doesn't work flash the OEM firmware via odin

[Q] [ HELP ] Connected to the Wifi network but internet working very very slow

hi guys.
I have got a new wifi connection installed at my home...i was on Omega Rom when i first faced this problem.As soon as i got my connection installed,i tried connecting my Note 2 N7100 to the network, it connected but the surfing was slow as if like no connection whereas all my other devices like laptop, Ipad and my bros. I phone is working smoothly on the same network.
I tried surfing on my office wifi network and it worked flawlessly.
Frist i thought that may be its some kind of bug which is their in the ROM so i switch to Alliance Rom V3 .....i did factory reset..wipe cache and dalvich cache and sadly still having the same problem.
Any ideas...?

[Q] wifi issue/no internet connection/jellykatv5/n7100

Since I moved to the new version of this awesome costume rom, I face a problem with my wifi connection.
The wifi connect with wifi, but there's no internet connection!!
What I did ::
I tried to check and uncheck all the options on wifi advance. I have install mj5 by odin. I have reinstall the rom several times. But nothing changed..
What shall I do now please..!!
I had the same issue once. I figured out that it wasn't the fault of my phone but the problem was with my wifi hotspot. I reset my wifi modem and made a new hotspot. That solved my problem. Hope this also works for you.

Please help Wifi is ON but no connection at all

Model of phone: LG G4 H818N MADE IN KOREA
(It is NOT dual sim version).
Hello everyone!, my little brother watch videos from an lg g4 (it is from my mother) so idk how this happened, but the main problem is:
Phone detects and also connects to wifi, but it wont work at all, there is not internet connection, and weird thing is that the signal is very good or excelent.
Things i already tried:
Factory reset from menĂº (Not from recovery)
Rebooting, booting on Secure Mode
Taking off battery saving stuff related to wifi
Tried to root but, i can't find any files to boot my variation.
Tried doing root with Kingroot from windows it didn't worked.
ALSO, wifi is working correctly in other devices, also i have 2 different wifi connections and with both is happening the same thing!.
Thank you very much in advance!

Wifi hotspot does not provide internet access

Hello, I once had a problem with the wifi hotspot operation on a Lenovo K3 Note - while the data connection worked fine and the hotspot set-up appeared to work, the connected device did not have internet access. This was solved when I flashed a new ROM.
Now I have an identical problem on an elderly phone (Ice-phone mini) running Android 4.3 that I want to use as a wifi hotspot. The symptoms are exactly the same as I had with the first phone. This phone is rooted, but I have not found any other ROMs to try, it is running the original rom.
I wonder whether this wifi hotspot problem is somehow generic, as I have come across it on more than one occasion. Is there any generic, or other solution?
I've tried Wifi Tether, but for some reason it fails. The log shows wifi interface configured but all the other operations fail.
Thanks.
