Hi there!
I'm having a really bad problem at the moment on my s4 (i9505). Recently I upgraded from stock (MDE) to pre-rooted (MF8). Since then, my WiFi has stopped working, and it seems to be the only thing that has gone wrong. When I toggle WiFi on, it immediately toggles off (both in the quick settings, and through the settings panel). When I mean immediately, I mean within 1/10 of a second.
I flashed another ROM over it (OMEGA V7) and nothing changed.
I feel as though I've missed something vital, and would rather work on a fix for it rather than flash stock through Odin and start from scratch. Any help is very much appreciated.
Check settings in WiFi. There is an option for using cell or WiFi based on which one is faster, disable it.

Thanks for the quick reply.
I already had that off (selected off by default).
Also check if your wifi timer is on.

No WiFi timer is also off.
This is very strange, I've searched google for hours and absolutely nothing like the issue I'm having.
Flash correct kernel

Ive had this issue before when my kernel and modem are mismatched but also when a weird setting is enabled... and I cant remember what it is.
Try a factory reset but do not restore your phone settings from google... only your contacts

So wifi will not turn on no mattrr what ?
And your not in airplane mode ?
This is beyond me then... I hope your hardware wasnt messed up.
Does your wifi still have a mac address ?

Not in Airplane mode.
I still have a mac adress.
No idea what's wrong. I literally JUST flashed a ROM. I've been doing this for almost 3 years and never have I seen an issue like this.
Might take the phone back.

I can't really say why this happens but a lot of times with this phone it seems that the MAC address to the wifi is somehow lost and by removing the /data/.cid.info file you can somehow reset something that makes things work again. I assume it's somehow tight to different wifi network chip drivers in different kernels but I'm not sure. On some ROM's I have tried I have to do this on every boot...

I can't figure this out and its driving me batty. When my phone is on wifi and the screen is off, it will stop syncing with Google.
I turn my screen on and the wifi signal is grey, then after a moment, it turns blue and I get my Google voice texts, gmail, etc.
Dies anyone have any idea?

Go into Wi-Fi settings/hit menu key/advanced/keep Wi-Fi on during sleep choose always.

well, i gave it a go and ran with it all day. still no incoming gmail or google voice texts when the screen is off
even when the screen is on, the notifications are very delayed. might it be a router setting..? it does only seem to happen at home..

what ROM/kernel are you running? Did you flash a kernel with updated wifi drivers and flash another (kernel) without reinstalling the ROM?
Otherwise, yes...check your router settings.
I'm sorry that changing out to wifi never sleeps, didn't fix your problem.

The stock Droid 3 ROM has a battery saving "feature" in the settings. Do you have that somewhere?

Make sure to read the changelog of the kernel. Some kernels include updated WiFi/Bluetooth drivers and if you switch kernels you must reflash the ROM to revert the drivers.

I haven't seen anybody create a thread about this, but has anyone not been able to enable their bluetooth without rebooting their device? I'll hit the bluetooth toggle in the settings and it just shots off right away. I'm not exactly sure what's causing it but I'm hoping that it's just a software issue since I use A2DP to listen to music.
EDIT: I performed a Factory Reset, I'll let you guys know if this problem still occurs.

Yeah same here, had that a while ago.. it happened after I used bluetooth for a while then switched it off, and then when I tried switching it on again after about 10-15 mins it wouldnt switch on. Had to reboot before it worked again..
Hope there's a software fix soon!

Would you recommend a factory reset?
I've had this happen occasionally on my N4, have to reboot in order to enable BT again. I'm guessing a software bug to be fixed in a future update. I doubt a factory reset will cure the problem.
Had this happen yesterday. I figured it was the nfc tag getting triggered too many times in the car mount? Simple reboot fixed it though.

I just experienced this problem as well. It was really annoying. Even toggling airplane mode wouldn't even work. On reboot, my bluetooth was already on though.

happens to me to. BT won't come on and need to reboot phone to fix issue.
i only use BT while driving as my music streams from the N4.
It's prob a software bug. i wonder if there's a service that we could kill that may get it to work again with rebooting.
Same here. Reboot fixes the issue for me.

First issue with my N4 I've experienced is this - happened just now and came looking to see if I was the only one. Normally I have alogcat installed, but hadn't gotten around to it yet. Next time it happens I'll fire it up and see if there's any useful messages or not If I get any info from it I'll share it here.

hi to anytone who is reading this.
here is how my issue started:
a week ago i rooted it
4 days ago my google play stopped working and would not steam any music( i didnt think anything off it just dragged and dropped my music onto my phone)
the next day google play store would not load and just said "no connection" and the re try button... i left it for a few hours and throught maybe its down ... the next morning i looked again and it wasnt up ... i noticed the signal bars and wifi bars was grey ... didnt know what it ment so i left it.
today, i rang gogole and they said do a factory reset... So i did.. grabbed a quick copy of all the files on there and hopped for the best.
it reset perfectly all datat wiped and everything... i tried to connect to wifi ... NO luck ... so i put my sim in and it wouldent read... restarted the phone .. still no wifi and no signal ....
what do i do?
i have the nexus 4 with a three simcard and my router is a bt home hub 3. 4.2.2 firmware
thanks in advance
luke
Start by re-flashing the factory images. If that doesn't fix it, you probably have a hardware problem.
can you please link me to a thread that explains how to do this safely???
thanks

wifi/data problem is always kernel related. flash a custom kernel and that should solve it.

That is incorrect.
Data issues can be radio related. By following my instructions he will flash both of these to stock which will help determine if the issue is hardware or software related.
Fixed it thanks to you guys. was just software so you guys are life savers!

idc what he does. the fact thay he also has wifi issues means radio is not a problem. it is very easy to say flash all stock. thing is to try solve the problem without fully installing the whole thing. that is why yours is not a "solution".

Did you not read the last part of my previous post, or are you just way too happy to argue?
Out of the blue I've lost my Wi-Fi capability on my S4.
I've restarted & turned off the phone to no avail. My phone shows up on my router's control panel as active as well as a couple of apps I have.
I've also forgot the connection & reentered all necessary info. Mobile connectivity is fine but as soon as I switch Wi-Fi back on, no tweets, FB notifications, etc.
Suggestions, ideas? TX

I don't want you to root either. It sounds like to me that it's a hardware issue with your phone.
Well, even though my router gave all indications that it was picking up the phone I tried a hunch. Rebooted the router & Wi-Fi is back!

Have noticed about once a day at random times, my wifi and data signal will disappear when using the phone. I have to switch airplane mode on and back off to get my connections back. Not a major Issue, but slightly annoying.
Anyone else have this problem or know the cause?

The toggle is greyed out on mine too and cannot switch it back on. The only difference is that I loose wifi and network connection. Mine is o2 UK unbranded handset.
Update: my connections are still active when this happens.

I'm getting the same thing here, the data and wifi icons occasionally disappear and the wifi toggle goes dark (as if it's not connected), but I'm still connected and get data just fine.

It didn't happen yesterday so will wait for next samsung update and see if that solves the problem. Unless it gets worse then I will factory reset.
