i have a problem with my i9505 updated to kitkat 4.4.2: wifi signal is very very low and i can connect only if i am near to my router ( max 4-5 metres) ... if I go little further ( or in other rooms where other phone works perfectly with wifi ), I lost the signal and the phone disconnects. Anybody could help me ? it could be something such as broken wifi antenna?
Dial *#1234# and attach what appears.

Firmware seems ok and you have wifi how I see. It isnt normal that ur phone haven't wifi and other phones yes. Wifi antenna can be broken or maybe is about config of the router.
problem is that I have 2 bars of signal even though i am a few feet from the router...

I don't think it's a hardware issue if it's only since his update.. to much of a coincidence for my taste.
From what I now, these antennas are very very sensitive. Is your phone using any sort of custom software? (kernel, recovery, ROM etc..)
I did a bit of googling and this issue is somewhat known. Advice there was to factory reset your device.

Maybe try flashing back to 4.3. If the issue resolves, just keep it until an update is published.
If it persists then it probably is a hardware issue, in that case you need to get it fixed.
All the best

It's not possible flash android 4.3 without void the warranty. And ODIN dont let you downgrade either. Unique solution if your phone don't have normal WIFI signal is get it to one service center.

I did a little reading and it appears you have had this problem for some time, end of April at least. You need to be able to determine if you have root. You are not sure what your recovery is...it also appears your phone may be international that you have been trying to unlock sim on. Not sure if I will be able to help until some of these questions can be answered.
Hi yes the phone is rooted and also is international unlocked it is a sprint l720 that I have the wifi was working before but not to its full potential it's signal was very weak and kept dropping out, since I upgraded the modem to the NAE modem the wifi will not switch on at all despite pressing the button for it . So I then reverted back to the previous modem which it was before which was the MDC and still face the same issue.
Have you done a basic battery pull? Had the same problem and that worked surprisingly. Left it out around thirty seconds.
Yep tried that still no joy wont let me switch wifi on
This is my phone info if that helps

Have not heard a response yet so I take it that my phone is a no go and will be able to get the wifi sorted . How much can 8 expect to sell the phone for I have really had enough with the sprint variation

My girlfriend had this problem on her unrooted s4. Wifi would not turn on , nor scan, or do anything. She was freaking out. All I did was take out the battery, sim car, and press the power button a few times. Left it that way for about 10 seconds. Put battery , sim , back in and restarted. Worked fine.

Remove the sim card as well as the battery. Press the power button a few times with battery and sim out. Put back together.
Flash the complete mf9 rom.
hi thanks for the advice i managed to get the mf9 firmware by odin on the phone and the WiFi started working again, im still facing the same problem of a weak signal unless im in the same room as the wireless router when it is at full strength tried resetting the router changing the parameters and still no joy , if any body has any other solutions pls share .
What router do you have? Did you factory reset your phone after flashing mf9?
I have a dlink dir 615 router which I updated to the latest firmware and also reset which didn't help and I never done a full factory reset as the phone rebooted itself after flashing the mf9 firmware on to it
Bump
Anybody help me out here ? What do I try to get this issue resolved ?
Still no replies that is fantastic !!!
Overwhelmed with so much support from this forum
Is your router dying? Do you have any other devices that connect to it?
Does your phone's WiFi work on any other WiFi network?
The router connects fine and strong signal to all my other wireless gadgets like ps3 ipad smart tv . I have these issues with nearly every wifi connection made regardless with my s4 the signal is very weak or nothing at all .

I have fullwipe all the phone becouse factory reset of official update of google deleted evrything but signal is impossible to be find by the phone wich recognize the sim and the number but not the signal
If I open btw the case and try to remove and reinsert correctly the antenna the phone will recognize the signal?

Have you tried to use the tool kit all in one (AIO) to bring the phone back to its original stock? If you have not, why don't you give it a try to see if that helps.

I picked up a Galaxy S4 Gt-i9505 from a friend to fix but I can not solve the problem. The problem is in Wifi and Bluetooth that stopped working .... I tried applying various custom ROMs and still did not work ... I've tried with Stock ROM with Odin and still did not work. Really do not know what to do, you're missing me swap the motherboard S4 now. But dont want to spend that much money. Some may say if there is any solution to solve this problem of Wifi and Bluetooh without replacing the motherboard
I think that there has to be a hardware problem when you've flashed that many ROM's and always went to factory reset.
I'd give it in for service (after having stock rom on it)

Hi mate ,
Not sure about the bluetooth but did you check this :
Open the built.prop
search for ro.securestorage.support
If it says true , change to false
Save and reboot
or
Turn off Wi-Fi power save mode on your S4
Type *#0011# on the phone dialer, then Menu Wi-Fi and turn Wi-Fi power save mode to Off.
In I9500 we had a similar problem and the only solution was to flash the param.bin file. BT did not work and WIFI direct did not work ( my case) after flashing it my problem was solve....

hi
Did you also re configure ( pair) the bt devices?
if so you could
Check the hardware ( antenna ) maybe is a connection lose or is defective
Or you could try to reflash (odin) stock rom again and see if it helps ...backup first included the efs
how i check hardware antena connection..???

extract the NON-HLOS.bin file from the ROM and use Odin to flash it separately by placing it in Phone or CP(newer version of Odin)
Untick auto reboot before flashing
wait for it to finish, then unplug your device and reboot manually.
that should work for you
Hi guys!
I had problems with my wifi and I found a solution online saying that I should delete these three folders:
/data/misc/wifi
/data/misc/dhcp
/etc/wifi
I done that and now the phone's WiFi cannot be switched on anymore (WiFi switch stays gray and cannot be turned on).
Is there anything I can do other than a factory reset or flashing phone?
Can anyone zip up those 3 folders and post them here?
Thanks !
Phone info:
Model: Note 4 N910C
Android version: 5.1.1
Phone is rooted.
Can someone please post these folders?

Do you have any custom recovery (CWM,TWRP,etc) ?
Don`t you have any backup (Nandroid) ?
If so , then restore the back up through the recovery.
If , not , then I think you`ve to flash stock firmware through Odin (at your own risk).
I have the same problem but i didnt deleted any folder. Just stopped working and i cant switch on wifi. Weird is that today when i was browsing google play from 4g data plan the window with wireless networks appeared and i was able to connect a wireless network. After 10 second was off again and the switch button is grey again. I am on stock 6.0.1 and not rooted. I think is a hardware problem probably the wifi+bt chip has some unsoldered pad to motherboard.

I don't think it is hardware problem. Restart and fully charge your phone and try to turn on wifi. Maybe you have some application (battery saver and similar) that prevent you to turn on wifi.

I'd take it into a Samsung Service Center and let them have a look at it. As there is obviously nothing you can do to repair the problem yourself.

i tried last night . I heated the wifi chip until i was able to move it slowly and the let it cool. Surprise after reasembly wifi was working ok all night and today at work i saw the same problem .
I think we must change the wifi chip but i cannot find it to buy... Any help ? Anyone knows an app or something similar to see if the chip is detected by motherboard? I think it must be detected if the mac adress of the wifi board is displayed...
My Device is failed to connect to any WIFI Network and I am unable to use Mobile Data.I have performed a Factory Reset but still facing the same problem.

Have you tried changing the connection method for wifi networks under settings?
Maybe re-flash the stock ROM?
Not sure what else to suggest. If these things don't fix the problem, there could be a hardware problem with the phone.
