Hmmmmm thats strange...
Your phone should have an error with the wifi drivers so try to flash the stock firmware of your phone.
Here is a guide by me
I had also faced this problem when i was using gingerbread. So, i made a backup of my phone and factory reseted it/wiped data using cwm and after reboot my problem was solved:good:
YOU can also try flashing stock rom using odin as stated by danyznd123
BUT FIRST MAKE A BACKUP
Hi XDA Peeps,
I owned my Samsung Galaxy S3 (Shv e210k) for almost 2 years and i would say that it is a wonderful device (variant). However, last week I had problems with the wifi connectivity. The Wifi range became shorter and it doesn't connect with my secured router and even public, "it says saved, secured wpa" i kept on pressing connect but it doesn't connect. Unless if im 1 meter from my router and I have to press the WPA button of my router for it to identify my phone, also with a public wifi it does connect but it drops on certain time and reconnects again, I tried most of the thread here at xda such as:
- *#0011# method which I have disabled the power saving mode
- Factory reset my device
- Reflashing stock firmware
- forget network wifi and logging in again
Am I missing something here? What do you think is the problem with my shv e210k? And would you suggest any solution to this?
Thanks!
Hi, thank you for using XDA Assist. I would try asking your question here, http://forum.xda-developers.com/galaxy-s3/help/help-thread-galaxy-s3-question-t2690307 Although it's not specific to your device it does cover all of the S3 variants. Also see this, http://forum.xda-developers.com/galaxy-s3

S4 has always been connected to my home wifi with no issues. Out of nowhere, I have no wifi. The phone see's all connections, but when I put in the password, the connect button will not highlight. I have factory reset the phone and it still does it. I do not know what else to try? Running stock 5.0.1. This issue goes for all wifi's the phone finds. No new apps or updates have been installed lately.
Wifi connects just fine with all other devices and my router has been reset.This issue is phone specific. Please help

Hi,everybody!
So I just got my S7 a few weeks back.It's been working properly. But there's this one thing that's been bugging me some of the days. Every time my phone connects to the Wi-Fi and if I don't use it, the connectivity just goes away just like that. And it shows 'Internet Not Available' . Even though I disabled the Wi-Fi from going off when the phone locks,the Wi-Fi still goes of with no reason. Is there a solution to this issue? Please help.
Also I tried resetting the network certificates and stuff,still doesn't seem to help out
No issue at my end

Sometimes i have this Problem too.
But only when this Option under WiFi is activated.
Sorry for German Screenshot :silly:
Disable it and test again?
Last week I spotted WiFi AND 4G together on my S7, also it starts running hotter than usual, so I switch to S7 Edge - clean never rooted latest update. But today same happened here ????
I can't figure out what happened, please help!
And no download buster activated
That setting is in developer options > networking > mobile data always active

How about "Download Booster" in Settings > Connections > More Connection Settings > Download Booster
That uses WiFi & Data simultaneously
Might also be "Smart Network Switch" under advanced wifi settings

I reinstalled my S7 and switched back to him if it happened again ....
You got WiFi calling enabled? Or VoLTE?
Or mobile hotspot?
Apparently caller ID apps will also cause this

I use Adguard and only see WiFi when on WiFi, and only see 4G when out of range of WiFi
It was same for me, but it just happened on both phones (one have never been rooted) and when I uninstall addguard again Wifi OR 4G icons, not both!
Maybe WIFi doesnt have internet access and phone switches mobile data on?
I found the Problem - SIM card I exchanged it and everything is OK for now
My bad, it wasn't SIM card but SD Card 200GB one
I have a similar problem. Very rarely, but it happens. Wifi and mobile data stay connected at the same time. And the bigger problem is that during this, one of the cpu M cores stays stuck on max load and frequency. Restart solves the issue, but i need to figure it out.
Android system usage goes up in the battery stats, but there are lots of processes included there. Is there an app that i can use so i can see in real time, which single process is ramping up one of the big cores? The phone is totally stock S7.
I will appreciate the help.
P.S. I really hate Samsung's garbage software !!
This was my solution
I recently downloaded a GPS spoof app and that's what was causing the Wi-Fi and 4g on it says it does it as app only works over mobile data. Due to some location pinpoint on Wi-Fi. Don't know if it's true but deleted it and gifted problem for me.
