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 .

Hello!
So my S4 i9505 always loses the signal when the lock screen is on, then I have to restart the phone/turn on and off airplane mode to get it back, but as soon as the lock screen is activated it loses the signal again. This only happens after the stock 4.3 update, I've also tried flashing to foxhound 4.3 but the same thing happens there, but when I flash back to 4.2.2 I don't lose the signal at all! does anyone know how to fix this?
I've got the same problem here. Using the Angels & Demons V16 (Android 4.3)

You need to update your modem to 4.3 to fix ur dropping issue. And please this has been answered so many times. Atleast use the search button. Thank u

Update the modem will fix this for you..
so I spent yesterday trying to get my bell Galaxy s4 unlocked so I can use it on rogers
when I got the phone I updated to 4.3 right away not knowing the issues it would give me
after trying long and various roms I decided to flash stock 4.2.2 thru odin
my phone went from 4.3 on i337vlluemk6 baseband to 4.2.2 on i337mvluamdj baseband
I was then left with a new issue....... I now couldn't enable wifi
so I flashed another rom and wifi was able to be enabled no problem(did not change baseband)
to my surprise I was able to unlock the phone successfully now using region lock away.
"VICTORY IS MINE!" I proclaimed
until I noticed something................I now have no sound coming out of my phone. I tried another rom and still no sound.....so I flashed stock thru odin once again. Again the wifi doesn't work and there's still no sound
anyone know what might cause this or how I can fix it? Phone isn't of much use to me if I can't hear it lo
Edit: thru scouring google I was finally able to find a solution on here. Apparently I just had to reflash stock 4.3 and it now works
another thing
even though the phone is unlocked I 'm not able to dial out on it
doing so caused the phone to lock up
this happens in stock as well as 2 roms I tried
the data connection works just fine and I'm able to browse the web with my LTE
I dunno if this helps anyone but if I go in to service mode I can't even select audio as an option.
It's there (number 5) but if I choose it it does nothing
Same issue
I have the exact same issue. I was trying to get to Google Play Edition which I have done many time before, but this time the baseband version changed. Now I also have no sound, so wifi and my phone is locking up when I make or receive calls. HEEELLLPPP!!!!
I nucked up BIG time.
I had xxuamdk 4.2.2 i somehow* managed to upgrade from kies. now i have xxuemj8 4.3 BUT no network connection my imei has not changed at all. I tried upgrading radio via odin but no luck lots of radios didn't even worked. workking ones cannot registered on network. i tried installing other roms and no luck.
BUT something is fishy in here. when my phone says not registered on network. i tried calling myself from land line i got ring tone. but there isnt any action om my galaxy. when i turn on airplane mode i got carriers unreachable message.
*there is stupidity. i still cannot believe myself WHY I DID IT. I didn't even back up my efs.
So i don't know how to deal with it. What should i do???

Download latest stock 4.3 firmware from Sammobile and flash in PDA section of Odin.
that may fix it.

i had this happen to my cspire phone today. It wont get past activation right?? Mine would try to activate on first one and go to different carrier like verizon, 2nd one just wouldnt activate at all. It acts like the modem is wrong but the sim card app's will tell you that its fully functional as does the settings menu, its just stuck in ROAMING mode.. I went through 2 of them this morning, My 2nd would keep trying to activate and then say no sim and crash out, so odin it back to samsung official status and go claim your warranty and don't touch it again. I did both with the knox 0x1 and far as i know that doesn't hold anything against your hardware warranty. Company should approve it as long as you have their original software back on there in the locked state.

thanks for your advice dude but i couldn't care less about warranty i have friend work in there but i dont have time to go there and i cant be away my phone for my job for more than 1 hour. even right now i have wifi hot spot to use my phone. i have to fix it or i will have to buy a new one.
OK try this.
Flash a custom recovery, Philz is my recommendation.
Boot to recovery (hold volume up +power)
Them in recovery menu go to mounts and storage and format System, cache, data, pre load.
Now flash stock ROM again and keep fingers crossed.

Just telling you man the carrier couldnt even fix mine with their forced data fix from their system. The phone gets screwed up and not even odin can bring it back. You can get someone to pull your modem from their rom and try to flash over but it will fail. Once its there its like it cant untake it. I returned 2 by warranty today, im done with messing with this pos phone if thats all its going to do for me. But go in the store tell them the sim card went bad, they will piddle with it and try another card and it will do same crap, then they will finally break down and offer u a warranty phone. Mine were FREE!! You said you cant be away from the phone for more than 1 hour, well at this rate NOTHING is coming through your device at this point?? So your hotspot does nothing if the phone doesn't have a data connection? Mine would get stuck with the roaming triangle, you could do 611 and hang up and 4g would come on but then go away again. If thats the case you'd save time and hassle by just taking it in with official a odin full restore flash on it.
Hi all,
I've had my phone locked on Tele2 (CRO) network which I needed to unlock to be able to use T-mobile SIM. I've used Odin 3.04 and followed the instructions to update modem to I9505XXUFNB9. I've managed to unlock the network this way and use my new SIM but the connection (both phone and mobile data) kept switching on and off constantly.
After that I've tried another firmware, namely I9505XXUFNDG for T-mobile but the problem now is that mobile is almost always off with no possiblity to connect and WiFi is blocked completely (security notification "Your device's security has blocked an action").
Basebands registered properly after every flash.
Phone is not rooted and me not being a power user would just love it to work as it was intended to
Followed the guide, all firmwares downloaded from here
Appreciate any help.
Might be onto something. After reading through this post seems I need to apply WiFi fix but I cannot tell which one to use for my phone (I9505XXUFNDG) as it's not posted. Kernel version 3.4.0-481100.
I've tried I9505_WiFi_FIX_MDM.tar and I9505_WiFi_FIX_MDF.tar but they just messed up the phone completely.
Thx a lot.

Hi ,
you should flash the fix for the modem you have installed , try following:
Flash another modem from the list there
Now flash the modem wifi fix for that modem
If still in trouble re flash stock and start all over again.....

Thx, did just that and now it works properly.
Much obliged.
a problem started to show recently; when i select LTE/WCDMA/GSM for auto connect network mode when the mode switches due to signal availability it doesn't get reconnected. i.e. while under LTE it works fine but if i move and get out of reach it should automatically switch to slower network which it doesn't. this works fine if i select WCDMA/GSM then the switches are fine but LTE is not available under this.
one more thing i noticed since i'+ve flashed the phone is that the upper part of the phone gets very very hot (a lot more than before). since the flash i've also had to replace a microSD card which died within weeks (not necessarily connected but worth noting).
any suggestions welcome.
Android: 4.4.2
Baseband: I9505XXUFNB9
Kernel: 3.4.0-481100
I recently went through the steps to go to 4.4.4 NI2 and root it with this guide: http://forum.xda-developers.com/showpost.php?p=55495211&postcount=1
During that process, I noticed my cellular signal wasn't working correctly, but continued on until I finished installing Rick's ROM V19.6 with a fresh install of safestrap and fresh install of Rick's ROM. Now that I have that installed and want to actually start using my phone now, my cellular connection is hardly working at all. I reflashed the NI2 modem firmware and now I am getting 3g signal only when I should be getting 4g. My ping is also very high 1000+ms. My download speeds are also super low (0.18 mbps down/ 0.59 mbps up). Something during all this process has really messed up my cellular connection and I don't know how to fix it.
I tried flashing the NCG Modem firmware and it wasn't getting any signal at all . It was just showing the circle with a line through it. I then flash the NI2 modem firmware and am getting the behavior as described above.
I ended up going to the verizon store and it took a new sim card and factory reset to fix it. No thanks on future rooting prospects for this thing.
I feel like a factory reset alone might have done it, oh well though, glad you got it fixed.

I had factory reset it several times myself. In any case, I am glad to have it working again.
