3G stops switching back after wifi?

This is a strange one. I have been using Fresh Evo 3.2.0.0 rom for almost a month and it works great. I wanted to try another rom so I tried the VirusRom... it was good but I liked Fresh better. So reflashed my Nandroid image and all was well.
But then I started seeing a lot of failed connections to the market and noticed that my 3G was not connecting. I live in Chicago so I am fully covered by 3G in this area, and even 4G in many spots. Usually when I leave a wifi area, the phone switches back to 3G almost instantly. But ever since nandroiding back to the Fresh Evo 3.2.0.0 rom, it only works after a reboot. As soon as I hit a wifi zone and then lose it, 3G doesn't switch back on.
4G and Wifi both work, but if I disable both wifi and 4g.. 3g doesn't come back without a reboot.
I've even switched off the Mobile network using the widget and the power button menu.. no luck. Only a reboot brings it back.
So then I even did the trick to get my PRI up to 1.40 and that worked fine. But no change in the behavior of 3G. When I reboot and 3G is working, it works great as usual. Just not sure why the switching no longer works. I even tried switching back to the rooted sprint stock rom.. same deal.
Anyone else having any issues?

yes, I have noticed this at times. Just happened to me. Failed connection when switching off 4g to 3g. Using fresh 3.2. But I noticed this as well on other roms. I had to reboot each time to get 3g working again. I also reset my data connection last night but it obviously didnt work.

I've been having issues with my 3G for the past two days. Similar story, I did and Nand restore and that is when it started.
I am getting an error code 67 everytime I switch from Wifi, 4G or even when I reboot to try and fix this. Usually if I let it sit it will come back, but the error message popping up is quite annoying.

Wish I had something more helpful to say, but I can just add that I'm having the same problems switching from wifi to 3g. Even after 3g turns on it will sometimes turn off again randomly and I will have no connection. I'm also running fresh. In addition my 3g signals are quite week. kinda a mess...

Weird. My phone did this today for the first time. The thing is, I've been on Fresh 3.2 for a month now, and I flashed the latest Baked Snack rom yesterday to test it out. It never did it while I was on Fresh, but today after turning off WiFi, it wouldn't connect to 3G for anything. No text or data transfer at all. After I rebooted it, it started working again, but my phone never did this while I was on Fresh.

I am having the same problem and I am using Fresh 3.2 as well. I did go to a different rom but then went back to Fresh's rom and that is when it starting happening to me. It will only pick up 3g now and then and even when it does my speed is super slow. Hoping someone comes up with a fix as I made my own post but no one seems to feel the need to reply to it.

Theories...
Same here. I'm on Baked Snack 1.7x
I know Fresh and Hero both use some of the same components. I flashed to Cyano and have had no problems with the 3G radio. It's very snappy switching on and off after wifi connects and disconnects.
I do know there have been one or two issues with the radio with people who are on the 3.28.651.x roms. (for instance, if you enable 4G then disable, sometimes it randomly turns off and on without you knowing until you restart)
So my guess is maybe the 3.28.651.x series is glitchy. You guys want to try going back to 3.26.651.6 and do some testing?

happened to me on stock. Had to reboot the phone to fix it.

This seems to be working for me today with no problems so far. I am wondering if a tower was down with Sprint putting up the 4g around my city. Will keep posted if it happens again but seems to be running like normal now.

This has to be network issues maybe the latest PRL.
Mine has did the same last couple days also on power on , it takes longer for 3G icon to kick in.
Signal flux has been occurring more then norm fast download - Upload speeds taking hit some parts of the day.

I am on 3.26.651.6 build and this was happening. I am no longer having any problems with this. I do feel this might have been a problem Sprint's servers were having. Seems like everyone started having the problem right around the same time.

It must be... Going to an older PRL didn't help, and there are a bunch of forum topics being created about this on other forums as well. Guess it's time to play the waiting game.
My issue is so bad right now even if I restart my phone, it doesn't even get data connection right away. 10 minutes waiting now and error code 67's keep popping up.

This just happened to me today. It took me awhile to connect the error statement to the fact the 3g didn't turn on after I turned off wifi. But I was able to press the 'data connection' button on the switchpro widget to turn 3g back on.

That is how I got it working a little bit last evening but as I said in my last statement it is finally working and has been all day. Not sure what the deal actually was as I did not change anything since 2 evenings ago. I am thinking that Sprint is doing something which is messing everyone up at one point or another.

cannot connect to a network at this time

Sometime I look at my phone and the is no service. I go to settings>serach for mobile network and get the message "cannot connect to a network at this time"
I have to reboot the phone to get a signal. Very disappoiting as its primary function is as a phone. This occurs when in a good coverage area.
Anyone else get this message from time to time?

I got the same problem.... still couldn't find solution yet. However, of you have this problem. You only need to turn airplane mode on and off. No restart needed.
in addition, do you using juice defender or not? Because I think it maybe because of it since I start have this problem few week ago... since I start using this app.

Hi, No I don't use juice defender. I've never had a phone do this before. I'm normally on call out in the night for my work, but i'm not confident i'm gonna get the call if its gone into no service. Well, i don't mind... not sure the boss is gonna buy it!
Hopefully someone can shine a light?..

Sudden Loss of Data on Nexus S

Hey guys,
This is actually my first post here but I do A LOT of reading on this forum.
I didn't quite find anything regarding my question (or at least a solid answer), however, so I've decided to post it up.
Has anyone else experienced a sudden loss of data from time to time out of nowhere?
I go from having Full Green 3G bars to grey bars out of the blue. I've heard the green bars is to let you know that you are connected to Google services but I am not able to access anything that uses data.
For instance, when I open up the browser, I receive an error telling me there is no network connection. When I open up anything else that uses a data connection, Market, News, etc, I receive the same error about there not being a connection.
This would make sense if I was moving and going in and out of service areas, but it happens when the phone is simply sitting on my desk and not moving at all. I usually use it to listen to Pandora while at work and have noticed that the songs cut in and out due to this sudden loss of a data connection.
I went from a Nexus One to the Nexus S and have never, not once, lost my full 3G bars in this same exact location. I personally believe its a software bug of some kind and have high hopes for it being fixed in the future. The N1 had similar issues when it first launched and Google / T-Mo were able to remedy that for the most part.
I am actually on my third Nexus S because the first two had some type of hardware issue; the first one's back button didn't work or light up and the second one had a blown ear speaker and would sound like a blown speaker in a car. As an early adopter, I expected this, so it didn't bother me in the least bit.
ALL of them did the same thing, so I know it is not just limited to my exact phone. This is definitely something with the Nexus S in general (or the current build of Gingerbread).
Can anyone shine some light on this situation? Thanks in advance and keep up the great work here guys!
---------------------------------------------------------------
UPDATE: Here are a few steps that I have taken in order to solve my sudden loss of data issue. I'm not guaranteeing this will work for you, but it has worked for me and a couple of users here on the forum.
Do the following:
Activate / Use the Sim Card that came with the phone (this is to ensure you are using the latest sim cards)
Make sure you have a 4G internet plan. (No t-zones, No web2go -- FULL internet only)
Call T-Mobile and have ask them to Reset your phone with their Towers
Here's a more technical explanation posted by Johoja:
1) Having network selection set to manual ( i.e selecting 302490 or TMOBILE) will result in No Service on a reboot. Solutions: - Have to cycle airplane mode to get it to pick up service (can be done with automatically tasker) - OR Use automatic network selection. (you can force wcdma only but that will reset the SMSC which is annoying if you go in and out of wind away/home areas and you want to roam.)
2) Being in a area with no service for extended periods of time 5+minutes(subway, basement, etc) will result in a dead baseband, meaning once you come into an area with service the phone will not reacquire signal, airplane mode will not work as the baseband is now crashed, cant maunally search for a network. Have to reboot to get signal. Solutions: -Use tasker to cycle airplane mode on and off when in no service areas i.e) search signal 4 minutes, airplane mode on 10 minutes. This will keep the baseband from crashing and possibly save battery. -Use NoBars to accomplish thesamething ( taskergivesyou a bitmore flexibilty of course but harder to use) http://www.appbrain.com/app/nobars-b...omdryer.nobars - Use airplane edit to avoid turning wifi/bt off when airplane mode is on. http://www.appbrain.com/app/airplane...kalti.airplane
3) WCDMA perferred does not work. - No solution
http://www.google.com/support/forum/p/Google+Mobile/thread?tid=747f398a6c1bb2b9&hl=en&start=40:

I read one users response on a different thread regarding something similar to the issue that I am having.
They said T-Mobile told them to get a newer sim card and that this may remedy the problem. In my case, this has been the only constant in the 3 phones that I have been through. I have had the same sim card for about 3 years or so now.
I will try activating the sim card that came in the box with T-Mo to see if this remedies the problem. Since I'm at work right now I will have to try when I get home later.
Does anyone think this will have any affect what-so-ever?

The galaxy s phones when first released, all variants, had issues of signal dropping from full to zero bars while sitting in one place. I remember because there were YouTube videos of it All over and it was shortly after the apple antenna issue.
Not sure if or how it was ever resolved. But it seems that Samsung may just have this type of radio baseband performance if we see all these individual units doing this. I don't know maybe others can respond.

I have the same issue as the OP. I travel to the same location weekly with NEXUS ONE, signal never drops in the T-MO Country here locally, and streaming CNET POD CAST never a hiccup, however, with the new NEXUS S, I would lose DATA Connection only, while the 3G will show full signal. I had to reboot the phone to get the DATA back.
is it the S issue or 2.3 issue?
food for though....

If you have T-zones or Web2go or Phones 1st web, you will have problems

I had the same problem too, now I fixed the problem. The thing was that had the wrong data plan on the NS, i had my old web plan from my hd2 which seems like different from the one for the NS. I restarted my phone after 5 mins off and now i have my internet working beautifly. A T-Mobile rep said that it was an error in the system that made the phone think that that was the right plan for the NS for a few. A glitch you may say, but all you have to do is put the right data plan that all, easy. Hope this helped and have a wonderful holidays everyone.

this is happening to me too, last night for a little while and today for about hte last 4 hours can't get connection back. i have full white bars, with 3g icon but can't access anything

So I activated the new sim card last night and I'm still having the same problem. Albeit it doesn't happen as frequent, but it still does it nonetheless.
I will call T-mo again to verify my plan. I am on a 1500 Minute Family Plan which includes unlimited data and messages. I will see if they need to tweak something and let you guys know if this remedies the problem.

Ok, it seems like the issue has been resolved after I spoke to T-Mobile earlier today.
The rep on the phone verified that the data plan I was on was in fact the correct one. He said he was going to reset the signal from the towers to my phone to see if this would resolve the issue. He asked me to turn my phone off for about 15 seconds after we hung up.
Since then, I haven't seen the problem arise again so my guess is that it somehow fixed whatever was going on.
I'll let you guys know if this changes and the problem occurs again.

What's with the CAPS? ?
On topic: i have a captivate and I can confirm that all galaxy S phones had droppend data. An official ota update fixes it so maybe you guys need to wait for something official. Isn't there a new firmware for the nexus S already? Try flashing that and see if you still have issues.

I know the Moment has that problem, after 3 updates samsung called it quits, I still have to reboot mine 2 to 3 times a day for data lockups.

@timur525 Yea, I'm already on 2.3.1.
I manually updated the first hour it came out hoping that it would solve the issue. The problem was still there after the update.

That shouldn't affect anything. My number shows up in status.
I had this issue resolved a few months ago as the push-to-talk app Tikl requires this in order to use it.
I was having the problem even with my number showing up. Call T-Mobile and have them reset you with the towers like they did for me and see if that helps you too.

I posted about this same issue on wrong section of the forum. Ive had this issue ever since samsung vibrant. I have applanet installed on my phone and some of the app that i installed accessed my apn and totally changed my apn setting to "Sirious application disabled.epc.tmobile" or something like that so i wyped everthing off from the phone and so far i havent had the issue ever since yesterday. Also i had the locale and language setting to korean so im thinking that might be causing it also.

That's what I remember too. I think its just an issue with the radio Samsung uses in all their phones. Might not be a way to fix it if even their new phones like the nexus s still have this issue. They prob would have tweakdd it by now if they could.

Same problem here. Xmas eve on shift and I have a phone that had no connection whatsoever (not even phone capabilities) this may be the one thing that takes the phone back. (If it happens again)

Have you called T-Mobile to see if they can give you a reset to the towers?
I had this done yesterday afternoon and haven't had the problem again since.
Also, if you'really using an old sim, I would suggest activating the one the phone came with just to be on the safe side.
If that doesn't help you then I would at least wait until just before your return period ends to see if there will be an update to address the issue.

I have this problem too but it only seems to happen intermittently when I am in an area with a poor signal (1 or less bars).
I've also taken to restarting my phone every day or two and It hasn't happened in awhile.

I had this problem with mine and when I looked it up it seemed I wasn't the only one. Most people seemed to think it was a hardware issue. I exchanged my nexus for a new one and the problem is gone so I guess it was hardware.

I got fed up so I called in for a new one sent to me. I hope this one is problem free!
It happens randomly but yes it seems to happen more when the signal is low.
I may have found the problem but not a solution. I noticed when playing with the phone that its always in Roaming mode. If you go to:
Settings>Wireless & Networks Settings>Mobile networks>
you will see that the "Data Roaming" feature is ENABLED which I believe has to be on since the phone is unlocked and you wont get data service if that is not enabled(for me anyway). Try Disabling this feature and just connect with a Wi-fI and play around with the phone. See if the issue still occurs. Mine stopped with this feature disabled and only comes back when it is enabled. The phone however is useless if this feature is not enabled if I'm not around any wi-fi.
Let me know if I'm right. Maybe someone good can create some sort of fix. looks like a software/program issue?

Having the same problem with my Droid X. Seems to be a software issue that is affecting Nexus S phones in Canada most severely, but also Droid X phones in the USA.
I'd include the link to the Google support forum thread but I'm too new of a user...

Its not tied to roaming but to 3G. In your case turning roaming off turns of 3G.

My xperia play randomly goes to no service then a few seconds later it goes back to full service. Has this ever happened to anyone else?

Sort of.
Right now I cannot get onto tbe android market or google maps. I can get onto google on opera and of course xda, im thinking its google. Reset doesnt help either.

That happens to me somewhat when I send MMS... but it comes out fine in the end... I don't know if that's the same issue with yours.

It used to do that a while back when I had just gotten the play, but now it never drops below 2 bars and always has 3g. I'm suspecting it has something to do with the enhanced 3g coverage upgrade they did in our area recently.
Sent from my R800x using Tapatalk

yeah. most of the time though, the zero signal comes when I wake my phone from sleep mode. other than that, full bars.

I did manage to get it working after some snooping. I went onto settings, applications, all, market and uninstalled the updates. Reverting back to the market I had when I first got the phone.
Ill mention that I messed about with download manager in the same directory in the settings, but I assume that rolling back the market did the trick.
Next day the same problem occurs, rolling back and clearing cache didnt help this time. Later In the day it fixed itself.
Im new to android so take what ive said with caution. At your own risk, but thought id mention as it could work for others. At the very least it could narrow your searching for a solution.
Hope it helps

Depends on the area where you are and the strength of your service.
For example theres a lot of interference at my job, to the point if I do any text messaging or facebook checking during the day my battery is near dead by the time I leave. However when I'm at home the battery will last all weekend if I don't play any games.
While I'm at work you will see it jump from 3G to nothing and back almost randomly and sometimes Facebook/market/etc work fine, other times they refuse to conenct for hours.

I get max signal at work, where I still had the problem. Signal wasnt my problem, I could get onto google through opera and on the xda app.

It is a firmware problem, at least for people with R800i models. The update 3.0.A.145 (first 2.3.3 pre xLoud update) did not have any Wifi or phone drops. The xLoud update crippled the modem terribly, making it work horribly where there was no issue before...

Hmmm I have a R800a with the R800i firmware. When the phone goes to no service it does drop cell signal AND wifi signal to nothing. I hope they fix this soon.

Ok problems back for me...again...
Sorry, I kind of hijacked this thread. I will start my own (after some searching) as my problem seems to be with google apps.
I can get on the internet, opera and xda come to mind immediately. But google mail, maps and the market all refuse to connect.
Thanks and goodluck

Think its working now...shouldnt have said (typed) that.
Either way thought id mention the latest solution thats working for me. Push the power button until you get the air plane mode option come up, put it into airplane mode, then turn off air plane mode. Turn the phone off, then back on, then with any luck it should work.
I have a funny feeling that the problem was due to an ota update, I also think the solution was an ota update. New to android so im not too sure sorry. Thought id post just incase though.
If I dont post back then my phones all working, or at least not suffering from this problem.
Goodluck
