I have a problem with the Wifi on my phone. I am running TNT's Official WM 6.1 Rom. When I use the phone without my SIM card in I can access the Internet via WiFi without any problems. However when I have my T-mobile SIM in it doesn't let me switch WiFi on. Is there a way to fix this? Thanks.
just changed my modem from MDC to NAE via Odin and encountered a lot of issues when on NAE modem WiFi wouldn't switch on the phone took ages to boot up could not dial any numbers or make calls kept coming up with unexepected errors and force closing, So then i went back to MDC modem and still no wifi tap the on button it wont come on the phone is 4.2.2 rooted MF9 and MDC any ideas to get this sorted . or advice on a diffrent modem or a update

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 seem to have no data when I flash back to Touchwiz. I need to do this in order to fix GPS since apparently it broke again in CM11. I was told the fix was to get a lock in TW and then restore my backup of CM11.
When I flash: StockRootedNAE.zip, I have no wifi/mobile data/cellular connection. I have the NAE firmware on my phone.
So how do I get mobile data on TW?
Any input?
No input at all...?

I have experienced several no data sessions on cm11 nightlies over the past month or so. I thought it was maybe the ng2 modem so I odin back to nae and had the same thing. wifi seems to always work but mobile data appears connected but wont actually send/receive any data. I have no idea what caused this however if I go settings>mobile network settings>prefferred network type and change it from LTE to 1x and airplane mode on then off then let it connect to 1x for a few minutes then change back to LTE then airplane mode on/off then it connects back to LTE for data successfully. Hope this helps!

My CM11 issue is GPS like I said, not data/wifi/cellular. The latter problem is on TW when I flash the zip I mentioned, even with NAE firmware...
I've searched for 2 months trying to figure this out. Basically my sim card will not be read due to the hardware issue so it is the motherboard, now the problem is i cannot enable WiFi due to not having a sim card inside the phone...when i was on 4.4.4 it says Smart Network Switch and something about not being able to enable due to no sim.....well i tried a custom rom to see if it would remove that feature which it didnt so i went back to 4.4.2 and it doesnt have the smart network switch but it still doesnt allow WiFi to turn on....now the funny thing is before i had the Sim problem i had WiFi on and it stayed working after the sim stuff happened, I factory reset my phone when i was going to install a custom rom before evening knowing WiFi wouldnt work without a Sim so obviously to my surprise when i went to turn on WiFi it wouldnt work, seems like the S4 has a stupid feature imo that if you dont insert a Sim it wont allow WiFi to be turned on. Can anyone tell me if under root or something i can get rid of that feature or some how turn on WiFi in the files or root section of the phone?

I have a similar problem. I have an AT&T S4 I337 that was used with Net10 Network and had the intermittent sim disconnecting problem but it was working well when ik worked. After I changed the Net10 sim to an AT&T non subscribed sim the Wifi, GPS and Bluetooth stopped working. I thoug hit was some firmware problem so I decided to Odin flash the NB1 Rootable Firmware but the problem persist ( can turn wifi and bluetooth on, and GPS turns on but cant get a location). I also tried the complete stock version of NB1 and also did not work. I constantly get a security Notice saying "Unauthorized actions have been detected. Restart your phone to undo any unauthorized changes". I restart but the problem persist. It seems to reboot into a Recovery booting and then restarts. The thin is that the Knox counter is still 0x0.
Did you resolve your problem? If not could some one help us PLEASE!!!!!!:crying:
Any one with that could help me identify the problem?
Hi guys, I am running stock July 2018 in UK (no root and new phone). Unfortunately, when I try to connect to WiFi Hotspot my phone can't sign in to the network (it discovers them fine). I have attached a screenshot. Can anyone help me? Thanks :laugh:
