[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.

[SOLVED] WiFi not working properly? 3G/4G stays on due "My Account" App

So when i am home i have my WiFi on, which means my 4g is off. Now when the WiFi is on, i can not receive or send pictures. Also cant use the web or do anything like that but just send and receive text/calls.. and reason to this? maybe i have certain settings on that i don't know about? If i remember right, my wifi worked properly a few days ago.. but i cant remember exaclty. Help please? Thanks

no one knows?

Power cycle your router?

I've been having a different wifi issue. at home I have only edge coverage but I have petty good cable internet so obviously I want to use my wifi but for some reason the phone connects to wifi yet still uses the mobile network unless I turn off mobile data. My wifi sleep policy is set to never btw. Any ideas?

Edit
Also if I turn off mobile data while connected to wifi then turn it on while still connected it stays on wifi fine. Its like the mobile radio is preventing the wifi connection from fully initializing or something

Same issue!

I am having the same issue. I have to go into airplane mode, then turn on wifi to actually be able to use it... otherwise seems to default to mobile radio...

I have the same issue..this is what i do to work around it though:
1. Go to Settings>Wireless and Networks>Mobile Networks
2. Uncheck packet data, and then check it again.
Once i do this, my wifi works again, let me know if it works for you.

yes, does seem to work, but agree it's frustrating.... Hope they fix this soon.

Got this from the battery thread. This actually fixes the wifi issue on my SG2
The program is called Llama and can be downloaded from the market. I deleted all the default events and just added these 2. Hope this helps for all of you with this issue.

- Install Llama and launch it
- Add an event called WiFi
-- Add condition: WiFi Connected (any network)
-- Add action: WiFi Sleep Policy (never sleep)
-- Add action: Toggle Mobile Data (off)
- Add another event called WiFi Disconnected
-- Add condition: WiFi Disconnected (any network)
-- Add action: WiFi Sleep Policy (sleeps when screen turns off)
-- Add action: Toggle Mobile Data (on)

Try freezing "my account". It toggles data even with WiFi is on. Try it and let me know.

Actually saw this tread and had Llama installed with these 2 profiles added and was till getting this issue... Going to try Freezing My Account to see if that helps... I know it helped with my wifi issues on my G2x.
Update: Nothing seems to work now. Can't have Wifi and cell radio on at the same time... can get calls but nothing else...

I've seen it occasionally as well. I haven't needed to reboot though. It usually recovers after I toggle WiFi on and off and mess with some other things.

I notice the same issue and I also toggle wifi on and off to get it to work back again.

Same here. I have to toggle wifi on/off and sometimes reconnect through wifi settings to get it back.

Recently I have noticed that the wifi on my phone stops working randomly...even though it says it's connected. Usually I can solve this problem by rebooting; should I return the device?

Yes, either return or warranty exchange for a new one, I have not noticed this issue with my device at all.

I've been having the same issue and it definitely causes excessive battery drain. Sometimes toggling wifi off then on works. Other times it requires toggling mobile data off then on.
I had it happen just now and tried freezing 'my account' in titanium backup as suggested and my 4g indicator immediately turned off. Sweet! It seems that 'my account' is the culprit!
Edit: I really wish this topic wasn't merged...I think there were a couple 'wifi problem' threads talking about different issues. To clarify, my problem was that while on wifi my 4G indicator would sometimes turn on and consume more battery and (sometimes) force all data to use 4G instead of wifi. Really annoying!

GS3 doent have a 4g "toggle" as you say...but you can make sure its enabled
settings-->more settings-->Mobile Network-->Network mode.
Preferred network mode should be set to "CDMA/LTE/EVDO"
If you have "CDMA/LTE/EVDO" enabled, anytime your in a Sprint LTE area your phone icon will switch from 3g to 4g.

doesn't it chew up more battery?

it shouldnt chew up ure bttery at all, as all it does is search the network for 4gLTE and if it doesnt find it, it will automaticly go to sleep and try again like 2 or 3 hours later or periodically as it tells u. .however u do need to have sprint automatic connention left on in order for that work. atleast thats what i got from reading the sprint connection optimizer information it gave me.

The optimizer isn't for the LTE. I hate that garbage so I always leave it off. As long as your preferred network is set as stated above, it will automatically switch between them. Side note though, it may switch back to 3g if you don't have a very strong 4 g signal. It likes to be weird.

Sounds like your thinking of a wimax phone. I I had a Motorola Photon and you had to physically turn 4g on and off on it.... I think most wimax 4g phones are that way.
Sent from my SPH-L710 using xda app-developers app

Do any of the custom ROMS have a toggle for 4g/3g? I live in a 4g area but sometimes the signal isn't strong enough so it goes to 3g. Quite annoying. It would be great to toggle 3g off and force 4g.

So I had s2 before s3, so I assume the s2 was a 4 -g wimax? It had a toggle widget.

Have you tried updating to the new radio? I believe they boosted the power to give slightly better LTE connectivity in those kinds of environments.

There is a way to force LTE on the GS3. I did it with mine so that I could map out the LTE zones with sensorly a bit easier while I was driving over the weekend. The way I was able to do this is you need to have Nova Launcher downloaded and installed.
Once you do this, long press on the home screen and go to "Shortcuts".
Next click on "Activities"
Next scroll down to "IOTHiddenMenu"
Then scroll down and click on "IOTHiddenMenu : HDR1X_Selection"
Doing this will allow you to force LTE only mode. Keep in mind you WILL NOT be able to make any phone calls while doing this. For some reason the GS3 requires the phone to be in LTE + CDMA + EVDO Mode to make calls even if you have a very strong LTE signal.
Another app I would recommend downloading is called OpenSignalMaps. Once you have the LTE only mode turned on or even the normal LTE + CDMA mode, you can use this app to refresh your network by clicking the little refresh button at the bottom left of the app in the Overview tab. What this does is pretty much turn your phones mobile networks on and off and then scan for LTE first before scanning for EVDO. I have been able to connect to many more LTE sites by doing this. Even ones that are fairly far away.
Hope this all helps. Let me know if you have any extra questions.

No data connection at all
I have the settings on GSM/HSPA/LTE, but lost data connection completely. Tried to restart and turned on/off flight mode - still no data. Voice in and out is OK. I finally managed to reconnect by repeating the process. Is there a better way to reconnect?
Thanks.

Check out "Network"

It takes you to the network screen as well

with the latest l13 radio my phone will not stay on 4g it is heavily biased to 3g and I do not know how to fix it. I am right next to the 4g towers.. ... any thoughts? Thanks

Thanks
Thanks. Unfortunately, the "Network" app would not run. So I followed a similar line, and found "3G Reconnect". It does not fix the connection issue. Any other thoughts?

[Q] Wi-Fi issues

Has anyone been having any Wi-Fi problems like the signal keeps dropping? Because for some reason my signal keeps dropping and coming back.
Swyped by Me & My GNII

I've had issues with the wifi connection as well but messing with some of the settings seemed to have worked for now.
If you have ruled out router issues...
I've read that you can try to uncheck the connections optimizer option in More Settings -> Mobile Networks may help.

i have noticed this. does this have any night time auto-off saving stuff like the htcs had?
also, I've noticed my gtalk won't stay logged in at night, regardless of Wi-Fi connected or not

Yup the Sprint Connections Optimizer not only is crap and cause wifi drops...it also wastes battery.

The current modem seems to *really* want to be on LTE. If you don't care about LTE you can disable it...settings - connections tab - more networks - mobile networks - change "Network Mode" to GSM/WCDMA. You'll still get HSPA+ speeds, but it should stay connected better.

Thanks man, it's just weird that the only way to get back connected is to make a phone call... I was at the time bike store yesterday and they mentioned something about updating the towers to LTE and should be over end of this summer... They said they are already ahead of sprint as in service at the moment and they are trying to be on the same page as AT&T and Verizon. I messed with the option by the way many times but didn't notice the difference yet but I will update the result on a following reply in the future. Thanks again
