3G not working...

I am running Fresh 2.3.3 with baseband 2.42.01.04.27 and for some reason, my 3G is not working. I have tried getting the stock radio and updating my PRL (my PRL version right now is flipz_01). Nothing seems to working. Can anyone help me with this?
Thanks a lot for any suggestions

I noticed that to. When I have WiFi activated, 3G disappears. I don't know if it's a real estate issue, or it isn't working.

Well 3G turns off when WiFi is enabled, but that is not my problem, my 3G just doesn't work, I have to rely on WiFi..

after I rooted my phone, the 3g didn't work. actually i'm not even sure if my 3g had ever worked before that. it's stuck on 1x.

Put the phone in airplane mode and leave it there for a minute or so, then turn airplane mode back off. That refreshes your phone's data connection. Then also try updating Profile in the Settings->About phone->System updates menu -- that refreshes your signal and data profiles with Sprint towers.

Thanks, but it didn't work... this is getting frustrating! I've tried everything! At least they're sending me a refurb, hopefully I get a dust filter this time around, too (and a "with Google" sticker on the back!!!!)

[Q] Mobile Data stays on with Wifi

Anybody else experiencing this.. Wifi is on and connected but my 4G-LTE arrows are still showing and flashing as if it was transmitting and receiving.. but my Wifi is on??
I am using Launcher Pro instead of LG Home so I have access to the power widget in the Notification Bar but not the LG Home power controller.
I just installed Power Control Plus and it seems to shut off LTE and 3G when you press the 3G button and can keep it off with or without Wifi on.

I've noticed this. It doesn't bother me due to the fact that I have unlimited data. If it want for that it would bug the **** out of me.

As far as I know, on all the android phones I've had, u have to manually shut off mobile data even when connected to wifi. There are apps that include this option when making "profiles" that get triggered (tasker, CPU tuner) but otherwise I think it stays on unless manually turned off. Maybe its not using mobile data but it appears to stay "on".

On my olds droid the 3G would turn off when I got onto a wifi network. I might just be special. Lol

I have the same issue. It actually goes further, because when I manually turn off mobile data through the Settings menu the data icon still stays on. If I use a tool like Dataswitch the icon goes away, but I never had to do that with any of my other phones.
The other issue with wifi that I'm having is that if I set the Wifi sleep policy to turn off after 15 mins of inactivity it can't reconnect after it turns itself off. So when I start using the phone again it just keeps trying to obtain the IP address of the network without ever succeeding. I've tried this on multiple networks. I have to turn off wifi and then turn it back on. Anybody experience this?
These issues aren't big but they're starting to make me question the quality of the LG Revolution and I may exchange it for the Charge.

I have this issue too, and it is annoying. I'm not worried about exchanging it, because I'm sure this will be addressed in the port of CM7 that TheCubed is working on.

Do issues like these usually get fixed in a port of CM7? Do you think the issue of mobile data staying on when it should be off will get addressed as well?
Any idea when CM7 for the Revolution will be available?

Why the 3g/4g radio still on when I connected to wifi

Hi I have had several smartphones and I've had all the 4g Verizon phone and when I connect ti wifi automatically mobile data turn off or at least icon disappear from status bar but with the revolution and with this bionic that's no happen somebody can tell me why thanks

Do you get the color change as described in this thread? http://forum.xda-developers.com/showthread.php?t=1261253

Mine does this
My bionic also stays connected to the mobile network when wifi is on and sometimes it will pull from the network instead of switching to wifi. the radio is all messed up on my bionic.

Well is not a mess I mean when I am connected to wifi my phone use wifi internet instead the mobile data but I guess with wifi n mobile data use more battery I guess I don't know the revolution is like bionic the same happens

I see this on mine as well. I know some people have indicated that it is not really connected to 3G, here is what I'm seeing:
When Wifi is turned on, the 3G (or 4G if lte is enabeld) sometimes stays on. Sometimes it changes to white (indicating that it may still be connected, but not syncing to google through that connection), sometimes it stays blue, and once in while it actually goes away, but not often.
Some other threads seem to indicate that this is just a display bug. However, if I analyze my battery stats, I think the connection is actually staying on. Here is what happens:
* With just a plain 3g/4G connection and no wi-fi, if I look at the battery stats for Cell Standby, the "time on" increases as expected. If there was a period when the cell signal was dropped, I will also see the percentage ot time without a signal.
* When I turn on Wifi and the 3G icon stays on, if I look at the battery stats, the Cell Standby's time on continues to increase, but not the "percentage of time without a signal" also increases. This seems to indicate that the cell signal is staying on, but it knows it is not connected and is searching for a signal. I'm not sure if this is actually eating up more battery like when you really don't have a signal and it is searching, but it is being reporting that way at least.
* If I install a widget to disable 3G/4G while on wifi, the icons go away, but I still see the same thing happening in the battery stats. This could indicate that it is still connected, or it could invalidate what I'm seeing altogether, not sure.
In any event, I'm not sure what the real story is here, I never had the icons stay on with previous devices (Droid X and X2), so I never investigated the battery stats. However, I see alot of people talking about their Cell Standby taking up a lot of battery, I wonder if this plays in to it.

yeah I don't think it's really on either. I verify this by using speed test. I know my speed at home and lte is faster. lol

When I use juice defender I disable mobile data when connected to a wifi SI icon disappear this happen with the revolution and bionic I don't see on tbolt nor charge

My 4g icon stays on while connected to wifi and stays blue. But according to speedtest the speeds reflect connection to wifi.

It should prefer wifi over 3G/4G. I keep this page bookmarked on my Droid that shows IP and ISP name to test it.

i dont like this either because every other phone ive had that hides 3g 4g the wifi goes in the place of it but thats the only thing so far ive found that i dont like

2 from me,
1. Battery life is tough. I must have this phone charging whenever I am at my desk or It will be dead by 8pm. I would consider myself to be a power user. I'm coming from an Atrix 2 and would make it through the day with only charging in the car dock.
2. No true gps toggle. I use the toggle switchs all the time, all others work but GPS.
Otherwise I love the phone it's very quick and I'm loving ICS

Disable att smart wifi thing, your problem will go away.

The only problem I've had was with the screen sensitivity. It's no longer a problem. I fixed it with a Moshi Screen protector.
It's thick enough to balance out the touch screen and it covers up all the Logos on the phone.
Juice Defender can also cause wacky wifi performance issues. You can adjust the custom settings in Juice Defender to leave wifi alone.
Smart Actions hasn't caused any problems with waking up any of the radios or wifi.
Wifi works best if you disable anything that has to do with automatically connecting.
When you connect to your wireless point, just click "remember" when it asks you to save settings. That way it should connect/reconnect faster when you are within range because it's not scanning. It'll just connect.
Anyways, from a security stand point you do not want it to automatically connect to any open network. Wireless SSID can be spoofed with a name change, and connecting to open networks is asking for someone to record your activity, or even launch SSL strip to fish out information on the secure sites you visit. Packet sniffing at a Starbucks free WiFi is easier than using 'One-Click-Root.'
So just avoid open networks and disable anything to do with auto connecting. It'll speed up waking up WiFi and it'll make you much more secure.
If you still have wifi issues just toggle airplane mode on and off.

I'm occasionally bugged with Smart Actions when it forgets to turn something on/off after leaving that profile.
Another problem i'm having the that the bedside dock app keeps crashing when i connect my MAHD to my desk dock, only fix i found so far was restart phone...

bump. has no one else had their bed dock crash and not start up again? I want to know if i should start looking for an app gone astray or something otherwise x.x

There's 8GB of space; how did 2 apps fill that? Go into setting>Storage and see what's really eating up your internal storage. I found that the camera by default saves pics/vids to the SDCard and I would bet that's what's killing your space. If so you can change the setting in the camera app and use the "Manage Internal Storage" to move over pics/vids that are currently on internal storage.

I've not had any wifi issues.
Having had this only 2 days, the only problem I've noticed is that there is noise when listening to music. Specifically using the standard Apple earphones and listening to Pandora. I also tried some other cheapo earphones and the same thing. I tried both earphones on my old 3g ipod and it was crystal clear. But this is really a nit-picky thing and I can only hear it on the lowest volume setting.

I get this notification asking for what keyboard input I want to use sometimes when I have the keyboard opened. I click it and it asks me what keyboard input I want to use. I have never installed any other keyboards and this has been happening ever since I got my phone a few days aho

Data and Wifi completely drop, have to do airplane mode to turn it back on

I don't know why, but this is a consistent problem and it's getting annoying. I will only have bars, but no wifi or internet connection. This just randomly happens and I don't know what triggers it.
I have to turn airplane mode on and off to fix the problem. Is there something that is causing this?

I have had the same thing happen,but only once or twice,I chalked it up to my home WiFi threw Comcast ,I've been having major problems with my Comcast modem dropping WiFi or to slow of a connection,think I have to replace the modem just been to lazy,but I have the smart network switch on in my phones wifi settings so I thought maybe from the signals switching so much it froze or something,but yea it did same thing I had no lte or 4G next to my carrier signal,the wifi was not allowing me to turn it on,or scan for networks,wasn't even showing any so I did the same thing hit the airplane toggle and it came back.

Sorry i have no others solution for it.

I just posted a thread about the EXACT SAME issue. It only seems to happen overnight, but when I wake up in the morning my wifi has been turned off and my 4G LTE isn't working. When I try and toggle wifi back on it gets stuck and never reconnects/turns on. My solution has been to restart the phone.
I'm thinking since this seems like a rare problem, that this is a device-specific issue. I'm going to try and exchange mine this weekend due to this problem and hopefully get a properly functioning GS5 instead.

Have the same issue (made a post about it already in this forum). Usually happens when there is a large fluctuation in signal. Grocery store where I get no service results in no service when I leave the store as well. Have to cycle airplane mode like you described.
WiFi hasn't done it yet.
Another forum member suggested it may happen if using an older style SIM, which I am (from my S3). I haven't been up to change it yet. What SIM are you guys using?
http://forum.xda-developers.com/showthread.php?t=2744472

I typically have this happen when I'm at home at night, while my phone is plugged in and on wifi. Just disconnects at some point overnight.
I'm using a brand new SIM provided by AT&T when I upgraded in store.
Very strange issue and is random. For instance, it didn't happen overnight last night.

My S5 just started dropping data randomly and causing my battery to drain with almost no usage... I tested using Skype in a good 4G LTE area and will start out with 4 bars and the 4G LTE icon but as soon as I try to initialize a test video call over Skype the signal immediately drops to either no bars at 4G or it will go straight to E!? I haven't had this issue in a long time and it just suddenly started. At first I figured maybe they lost a tower but now this is going on almost a full week. I've got unlimited Data so I know that's not the issue, it has a brand new SIM... I'm going to AT&T and see if they have an answer or if they'll swap it out. Annoying!
Also annoying that sending a simple text will fail... ugh no root and now no data! :what::banghead:

I've had this happen several times, but only at my work. Reception is poor at my office, and the company WiFi requires browser-based login each hour, which I switch to many times a day.
The phone basically stops using all radios EXCEPT bluetooth, showing a circle with a line through it. I've been rebooting the phone to restore connectivity, but will try toggling airplane mode next time. I haven't noted any strange battery drain.
I haven't seen this issue when wifi is disabled.
I didn't notice it locked up a few days ago and drove home where cell reception is very good. The phone didn't recover until I rebooted it.
I have a brand new SIM from ATT and use a Gear 2 (which is greatness, btw)
I've done the following:
1. disabled the damn ATT hotspot app
2. Disabled/enabled the Wifi connection check setting
3. Did a full factory reset
This is getting close to a deal breaker for me.

As an update...
I have this issue basically every work day with the aforementioned environmental variables
Today, I:
Disabled Bluetooth (left the gear at home)
Disabled wireless
Switched radio to 'LTE/GSM/CDMA Auto' with instructions in this thread
The radios haven't locked up and reception is much better.
I'll try leaving WiFi/BT on and use my Gear again next week.

For anyone who is still interested, changing the modem setting seems to have resolved the problem for me. It also improved connectivity in weak areas a good deal.
Unfortunately you must enter the key sequence to toggle the radio each time the phone is restarted.
