[Q] Can't enable Mobile Network...help?

Hi guys,
You know how when you enable Airplane mode Bluetooth, Bluetooth settings, 4G, 4G settings, Mobile network, and Internet sharing become shaded and you are unable to turn them on?
Well, for some reason my Mobile Network option is shaded/unselectable, although I am certainly not in Airplane mode. In fact, both mobile network and internet sharing are shaded, yet M.N.'s box has a green checkmark and underneath it says, "Turning on...". Still, it remains like that without any change.
Since this issues has occured, the 3G logo in the status bar has disappeared, which leads me to think that the phone isn't enabling data connections, not that there is something wrong the MetroPCS's end.
The only thing I could think of was that a few days ago, I was playing with turning on/off 4G setting and that I turned off/on the 2G-3G toggle in the Extended controls widget; that however, only directed my to the Mobile network settings where Data Roaming, Data Roam Guard, ect. are all enabled.
What should I do? I tried being as detailed as possible, and hopefully there is a solution as I am getting really tired of no internet on my phone. Thanks for any help.

By any chance to you have an older version of switch pro installed. This caused issues with my mobile network a while back.
If so, uninstall it.

I do not have it install, but I will try uninstalling any app that I have installed in the last week; maybe you are onto the something there. I do have a couple of control/settings/toggle widgets. I'll report back.

[Q] Ready to throw my GN against the wall. Wifi wont stay on!

Hi all, Im having a problem that is slowly driving me insane for the past 2 weeks. I surely cant be the only one. Anyway, I generally move between home and work daily, both have WIFI. When Im at home Im connected, all fine. I travel to work, WIFI isnt connected, again this is normal. I get into work and when I expect it be connected to WIFI it isnt, WIFI is off and I have to manually turn it back on to get it connected to WIFI again. Why do I have to do this? Why have all my other Android devices just worked normally and reconnect to known networks. Its soooo frustrating
Anyone have same problem or have a resolution?

What rom?What settings in phone wifi?

Both Stock rom, with and without the volume fix, and Modaco MCR4. Wifi settings are set as WIFI on even during sleep.
Is there some settings Im missing somewhere other than in Settings > Wireless & Netowrks > Wifi ??

Nope these are the settings.The strange thing for me is that your wifi turns off automatically

Try going to advanced WIFI settings and disable 'Avoid poor connections'

Yep. Try that. Only thing I can think of. My wifi was flaky with that setting on even 4 from my router. If that doesn't solve are you using any kind of task managing àpp?

I have posted this in other people's threads in regards to poor wifi reception. I recently purchased a 9250 through bell canada and have the same problem.
I have turned off the 'avoid poor connections' as well. It turns on and off on its own and can't get through a download of more then 5MB on wifi.
It will also reconnect on its own if I have left wifi turned on. I would say while WIFI is turned on I may actually be connected 30% of the time. This is 90% in 2 feet away from a router.

I'm having the same issue (wifi turning itself off) - noticed it the other day and just assume I'd caught the wi-fi button (I use extended controls). Happened again this morning and also just now as I got home.
I've not modded anything on my Nexus (4.0.1) - avoid poor connections has been disabled for a while.
I may test the theory, but betweek home and work is a wifi enabled bus journey, I never use it but it always tells me there's a wifi available. I might turn wifi notification off and see it if turns itself off before I get to work in the morning...

Left home with wifi on... Got to work and wifi was off? Wtf?
Could it be extended controls?

You are not the only one, it's happening to me in exactly the same scenario. Oddly enough it hasn't happened today.

i cant make out of your post thast the wifi on/off button turns of? or just the connection to the wifi adres?
i dont know about any sleep or auto turn of policy's as i didnt try it(i always turn off my wifi when travling)
but if its the last thing.
than the problem might not even be the GN.?
but the router it self.
even computer's and laptopt can have problems when the password is too long,or to different(hard characters like :';/.m,[email protected]#$%^&**(() ][ )
it might also be the MHZ setting,as the 20MHZ has wider range but can be disorted by machines like microwaves.
but the 40MHZ has lower range but wouldnt be disorted.
as there is also the channel option thats has been set wrong/or the pasword encryption. or any other router conflicting with the router you want to connect.
it might also be the router not liking your GN.(as my spica doesnt conect to my router at home,but all my other devices do.my router doesnt want to give a IP to my spica.)

It just happened to me again now, left the office whilst wifi was on and connected. Grabbed some lunch and returned (about 20 mins) and now my wifi button is set to off and I need to set it back to on.

Are there any policiys or settings for auto off?
you might also want to look into the power setting's,might be a power save feature.
And you are running stock? or??

Can't see any policy settings or any power save features. Running stock.

somehow I have fixed it. Problem is I don't know how.
Here is what I did in case anyone else needs help;
*From the 'My Vodafone' app, select wi-fi finder, in settings untick 'Enable BT Openzone'
*Settings, wi-fi, advanced, untick 'Network Notification', untick 'Avoid poor connections'
Not sure which of the above actually fixes it but my Wi-Fi has been on for about 1 1/2 days now.

Have you or when did you upgrade to 4.0.2? As the changelog mentions a wifi fixed. Only upgraded this morning so won't see if it has worked until I get home...

So I am still having this problem since day one. I have travelled through 3 countries and multiple cities and tried to use WIFI in at least 20+ different instances and the problem is the same.
It connects right away (really quickly actually) will stay connected for a bit then eventually loses connection.
I can't download any of the big packages for the games and so I can't play them. I won't use my data connection for anything over 100mb.
I got a message for an update yesterday. Updated the phone but I see no difference in the Android version number.
Anything happening with this?
I thought the update i was downloading was 4.0.2 but i guess it wasn't.
I am familar with updating and flashing from the galaxy s. But I want to use the phone completely stock for while.

I have just returned my nexus for a replacement. Lets see how it goes.
So far I have had the power shut off once while toggling the wifi widget (never happened on my other phone). And the wifi has disconnected twice. I have just done the update (not 4.0.2) and it seems to work a little better.

Called samsung yesterday after getting the replacement phone when it had the same issue (just as a reminder I have tried it on numerous routers/ap's) and they said they hadn't heard of the issue.
I said I was just calling to provide some feedback. They told me to return the phone yet again. I obviously believe I don't have a problem with the hardware at all. I figured if store let me return it, then why not.
Anyway onto my 3rd one today and the exact same problem.
I think that even though I am turning off "Avoid Poor Connections" it isn't actually turning that 'feature' off. Every so often and only if your watching the wifi settings it will say that it disconnected the wifi connection due to low signal.
Mind you all of this is 1' from my router while sitting at my computer. My galaxy S is sitting beside me and has maintained a wireless link to the router the entire time.

[Q] WiFi - mobile data switching problem

Since updating my N7100 to 4.4.2, it is not reliably switching between WiFi and mobile data when it should. Sometimes it does, sometimes it doesn't. Until I updated it was always !00% reliable.
I found the new setting under the WiFi tab - 'Smart Network Switch', and this is checked.
Has anyone else had this problem? Any suggestions to cure it? The phone isn't rooted and I don't want to do that.

You got to disable Smart Network Switch cause whenever mobile data is stronger than wifi signal (even, let's say for a second) it will disconnect from wifi and vice versa.

Thanks. I'll try that.
It seems that the Smart Switch isn't working as it should because sometimes when I get home I can hold the phone right up to the WiFi router and it still doesn't switch to WiFi.

Normally no need for network switch, only on special occasions when needs continuous connection and wifi isn't that strong whereas mobile is.
If you untick (disable) you will see, that coming home into reach of wifi will automatically change from mobile to wifi. :good:

I have it unticked now and I will see how it works. Will it be exactly like it was before I updated to 4.4.2?

Wifi issue

Does anyone know how to stop the WiFi from turning on automatically ? I have all of the options for the WiFi off and I'll turn the WiFi of but my WiFi will still turn on and say there is a hotspot available.

You mean the options under Advanced in Wi-Fi settings you have off right? If so I am not sure I have not noticed my Wi-Fi coming on without me hitting the toggle.

Yes all the settings in advanced are unchecked,I will turn off my WiFi and next thing ya know I'm getting a notification that there is a hotspot available and sure enough my WiFi is on again! Its starting to get annoying that I get the hotspot notification all the time

That is odd, one of the options under advanced is to make it so it does not try to connect to hot spots in general, also the other says to make it not scan while Wi-Fi is off. If both those are unchecked and it is still happening then there is some sort of issue I would guess. Hopefully someone else with the issue pops in here after a bit.

Me too
Yes, this is happening to my Note 4 as well. All settings in WiFi>Advanced are "off" and when I go walking through the neighborhood and turn on the phone I get a screen showing a list of wi-fi networks.

Im gonna guess everyone has saw this already but thought i would post it anyway. In the advanced menu in wifi,there is a section called Always Allow Scanning. Description says "Let google location service and other applications scan for wifi networks, even when wifi is off". Sounds as if that could be the issue but if everything is already unchecked in the advanced settings menu, then im at a loss as well. Im gonna test this on my Note 4 and see if i am getting the same issue you guys are getting.

Nope no issues here i don't get that i turned it off, and i would know this cause if i walk in Walmart i use to get that on the the Wifi Hotspot not no more since i've turned it off, use to tell me the same for kmart or the AT&T Store where i live no more since i've turned it off!

Try disabling AT&T Smart Wifi. Could be the cause, especially if its alerting you to "hotspots".

I have the T Mobile version and it does the same. The white menu pops up telling that there is Wi Fi available, listing hotspots.
On my previous Note 3, it did not present itself as a page over my screen even if I had Wi Fi turned on. I simply had notifications of available wi fi's turned off. But it seems with the Note 4 one has to turn off wi fi completely for this to not show up?

Check in Location Services... Specifically the google stuff. One of them allows the use of your WiFi & GPS data even if they are turned off... Meaning if you choose the high accuracy mode (instead of GPS only) the location services will periodically turn those things on to better pinpoint your location (and send that data back to google)

Does anyone else's WiFi randomly turn on/off?!

If I'm home, chillan out, connected to my home WiFi, sometimes my wifi will just randomly turn itself off.. And then when I'm out (let's say I'm driving around) my WiFi will just randomly turn itself on. I don't get why the hell it does bc it never used to! I have connections optimizer deleted (using Titanium Backup) and I have "always allow scanning" OFF and "keep WiFi on during sleep" ON. What gives....?!

Lol you might have to flash to stock rom to fix this

I'm on the stock OE2 ROM... just rooted.

in my opinion the S6's software optimization is really really bad having a lot of bugs and glitches. I won't be surprised if there are weird phenomena happening in the phone if rooted

Disable the ironically named "Connections Optimizer" to prevent random dcs from wifi.

I am also experiencing these issues. It usually happens when the screen is off, and I can tell because when I turn the screen on it says at the bottom "Connected to WiFi Network <name>." I am finding this quite frustrating. I found a thread saying that you need to switch the wireless security on the router from "WPA2/WPA Mixed" to "WPA2 Personal" but it did not help my situation after doing this. I am still searching for a solution.

Hello, thanks for your input! How exactly do I set a static IP for my phone? I actually don't think my phone's IP is changing, but it's worth a shot. Thanks!

Mine will turn on Wifi on it's own. When im out and about as well. Connections optimizer is off. Always scanning is off. It's annoying because ill be using my hotspot and then itll turn wifi on by itself and turn off hotspot.

EXACTLY what happens to me bro. It's very freakn annoying.

Same issue here
I have enabled the hotspot hack using GTools and when I wake up screen to log in I get the message warning me that if I enable Wifi the hotspot will be turned off. I have already frozen connections optimizer so I know it's not that. Something keeps trying to turn on Wifi while I have the hotspot enabled. Have tried looking for the app or process but can't seem to get rid of it.

Me Too
Just chiming in to say that I've been having that same problem too, ever since I got the phone (which I rooted and used GTools the day I got it...LOL). Hope someone figures this out. I've tried everything I can think of and that I've read online.

I have the same exact issue of the message warning me turning on wifi will disable hot spot but I did not use GTools to enable hot spot. I used that other method using my MDL, I believe.

are you using the DUN hotspot method?
Mine does the same thing and has been ever since i got it. I don't know if using DUN APN type is the cause or not but i suspect it is.
