Wi-fi should work the same, if anything you should have data or network problems.
Try booting into recovery (Volume Up + Home + Power, hold together). It doesn't require root, you will be in Samsung's stock recovery.
Clear only Cache then reboot your phone. This will not clear your data or apps, this will simply delete their temporary files and force them to re-configure themselves to adjust to your current phone's state.
Maybe try connecting to a different wi-fi connection?

1st: make EFS backup (important! )
It is essentially a software issue. If you are on custom ROM, try flashing Agni Kernel (risky business). It should work.
If not, do a full data wipe / factory reset. Also format internal SD card. (Move your important stuff to external SD card and remove it for safety reasons)
Flash stock ROM via ODIN. The problem should be solved.
Press thumps up if you found this suggestion helpful.

@nilz_rokx - have you managed to sort out wife issue?
Think mine is the same issue. Updated from 4.1.2 Jellybean to 4.4.2 Kitkat. Now wifi will not switch on. Flick switch to right only to see it flick straight back.
Didn't really want to re-flash.

1st thing: go to stock recovery and do a wipe data/ factory reset and wipe cache partition.
If problem persists, only then flash the firmware.

WiFi issue after ota tab 3 7in SM-T210

Hi all i recently bought a no fault customer returned tab 3 7in SM-T210, Today I received my tab 3 and after the first boot I was offered an update, Build number KOT49H.T210XXBOA3, dated 22 jan 2015 at 110mb.
After the update had finished I was unable to connect to my WiFi, it would say connected but the settings app would freeze sometimes with the message that settings is not responding, if I do manage to get out of the settings I am unable to use the internet as all apps say no connection, even though the WiFi icon is showing as connected. I have also found that changing the screen off time to 1 minute cause's the device to soft reboot ( No Samsung galaxy tab 3 screen / bootloader )
I have tried doing factory reset but that didn't help,
Could flashing the full 828mb stock ROM via Odin possibly fix these issues?
And if I do use Odin to flash stock my warranty should remain?
Sorry for the long winded post, and thanks in advance for any advice given

Why is t210 so many issue? seriously!?
If one thing i need to clarify that doing any custom modification on the device will spoil your warranty. However if you did firmware stuff from kies will not remove your warranty. I would choose to flash into new firmware by using odin. But if your case you can do a factory reset then followed by kies and see if it is working. If it is not, download stock firmware from the net and flash it with odin.

thanks @Jacker31 for the response, i know about voiding warranty there is no custom software on it YET lol, only just got it out of the box, i am new to Samsung devices so i will do some research into kies, just don't want to void my warranty trying to sort it out.

I don't know if it's the same problem with my wife's tab t210. when you turn on the wifi it connects but around many seconds, the wifi icon is gone. and in settings the wifi freeze. i've done rebooting, restore factory settings but it didn't fix the problem. but when i try it to connect via my phone tethering it connects and the wifi icon stays. i check the tethering settings it was put on wpa2, but on my router it was just on wpa. So i change it to wpa2 and the problem on my wife's tab is gone.

Hi guys, so I installed kies3 but when I click the firmware upgrade button I get this message 'SM-T210' dose not support initializing. even though i had USB debugging selected. I also tried while the device was unplugged by entering the model and serial numbers but got the same response.
If I flash a stock firmware by Odin will the device log it on the flash counter? as it came with a 12 month warranty and i will send it back if i cannot fix it myself.

You should send it back because of the warranty, anything could happen (I meant for the warranty) if we do something.

[Q] GT-N5110 Wifi not working after OTA upgrade to Kitkat 4.4.2

I have upgraded from Jelly Beans to Kitkat 4.4.2 via regular OTA upgrade provided by Samsung on my Samsung Note 8" GT-N5110. Since then I am unable to use Wifi on it. My device is NOT rooted and is running on original Samsung software upgraded via OTA.
I have tried to clear cache and then factory re-set as well and still can't get the WIFI button to sometime even select available WIFI networks. So issues I am facing are summarized below"
1. After factory re-set and clearing cache via Power+Vol Up option, when I tried to setup from scratch, WIFI would not turn on at all meaning device would not be able to scan for available WIFI network or would do so but after long time and if it does show available Networks and I select my home network with required security (WPA2) and password, it would show status as " Saved" rather than connecting to this network. The device would not connect to selected network even after multiple tries.
2. When trying to turn wifi on, device would not show "WIFI" button to Green but instead would stuck at "Grey" color for ever unless rebooted and re-tried many times. The grey would turn green when selecting advanced option or tabbing thro' back button but would not scan available networks then. If it would scan thro' Networks, it would just save selected network even with correct security option and password for it.
WIFI not turning on has made this device a piece of junk for any meaningful use. Any suggestions/ help would be highly appreciated. Again please note, my device is UNROOTED and running on original firmware provided by Samsung via OTA upgrade.

Hi XDA Gurus,
Any one can direct me to right section that has solution for this issue if it is a repost? or help me get an answer?
Thanks,
R

Anyone find an answer to this?
I ahve had no luck, same exact issue, anyone have any ideas? thanks

If you don't mind... try odin 3.09, flash philz recovery, factory reset for wipe clean for fresh install option, and boot to downloader. Flash a firmware from sam mobile, or the get a usa version in the development section.
That should flash a clean install after a wipe

No Wi-Fi, no Bluetooth and no FM Radio [D855]

I'll try to give as much information as possible.
Yesterday I was surfing the internet and suddenly my phone froze and randomly restarted. After that I wasn't able to connect to wifi nor bluetooth. I was running android 6.0 with 30B modem, rooted and with TWRP. After that I flashed Modem from v21C Firmware. I don't know if doing such was responsible for the next thing, but my Wi-fi mac adress and bluetooth adress disappeared from Hardware information. Note that my IMEI information did not disappear.
After that I did a full factory reset with .TOT method. That didn't solve my problem. Tried upgrading to lollipop, did not work. I've done like 10 factory resets only today, I've tried to fix persist partition following this guide http://forum.xda-developers.com/google-nexus-5/general/guide-to-fix-persist-partition-t2821576, same results.
In 4.4.2 and 5.0(all versions I tried from lollipop), both wi-fi and bluetooth adresses showed up as anavailable. Sometimes after rebooting, my phone would connect to wi-fi and show my mac adress, and would crash after 30 seconds..
On 6.0,my mac-adress shows as 02:00:00:00:00:00 and bluetooth adress as unavailable.. Need some serious help here, tried so much stuff nothing worked..
I'll attach some screenshots that may be useful
Any questions and any tries to help me are highly welcome.
Enjoy 6.0 on your phones and thanks for reading :fingers-crossed:
-------------------------
Edit:
Adding some logs. Half a year passed, no solutions.
1 out of 100 reboots wifi works. I've gathered some logs of 1 of the moments wifi works. Hoping someone can figure something out. Tried lots of roms, nothing seems to work.

Forgot mentioning that both wifi and bluetooth show as trying to connect on notification bar, but when I go to settings and press on them, both say "turning on (wifi or bluetooth)" when the button is grayed out and off..

did you tried to use the cse flash in flashtool to fix this?

Did CSE flash, normal flash, TOT factory reset, wiping wifi's definitions.. Nothing seems to work :crying:

More info:
During the night, I removed the battery from the phone and booted my phone. After that Bluetooth would work, and Bluetooth adress would show up on "Hardware informations". Then, I turned off bluetooth and tried to put it back on. Bluetooth adress disappeared and my bluetooth would not turn on. Hope anyone helps..

How about your imei?

Also, forgot to say that, if I try to turn on wi-fi, if I connect my phone to my computer, computer will recognize I attached something and will start charging the phone, but I won't be able to transfer items to my phone since it won't appear anywhere on my pc..

I think I found a solution but I can't test it since I'm having problems connecting my phone to my PC ( another problem appeared..)
May I ask yo to install busybox and try this on adb?
adb shell
su
busybox iplink show wlan0
and see if it shows your real adress, if it does
busybox ifconfig wlan0 hw ether (adress)
busybox iplink show wlan0

I don't have my phone with me, sent it to repairing. Any news?

I'm having a very similar issue. Wifi and bluetooth won't turn on and cycle. On some reboots, Wifi will turn on but the phone will shut down shortly thereafter. I've tries several different ROM's and can fix the Wifi, but no the power not the shutting down.

I'm having the exact same problem but a bit worst. I can't even turn my phone on. Phone came back from repairing, guy couldn't fix it. Tried some rom's, many "fixes" from the internet, nothing. Seems like the only way to solve this will be by hardware..

exactly same problem with my g3 too
even i was using stock 30b firmware and after one week of usage it suddenly crashed and stuck in bootloop hence downgraded to lollipop and tried all roms,factory reset,different modems etc but still not fixed
waiting badly for an solution

I'm having pretty much the same problem, along with overheating and screen fading. I'm using stock Lollipop, never rooted. I've tried a factory reset and a new battery with no results.

Any solutions?

Guys I've sent my phone to a local repair shop and they said they took it to LG's official partner.. I've been waiting for a while and it doesn't look good.. A friend of mine bought a g3 recently. I suspect this problem comes from a corrupted or missing file. I'll ask him to help me on checking files if the local shop can't find a way to fix the phone. If everything fails, the only possible solution I see is a new main board or a new phone..
