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.

MyTouch losing data signal

I keep having a dropped data connection issue. Over the past few days it will randomly drop data where previously i would have around a 5mpbs d/l connection. Sometimes it will take me rebooting the phone to restore the connection. I am beginning to think my phone is having an issue. Has anyone else experienced data connection issues?
This is really annoying the hell out of me now when I have had no connection issues with this phone until the past few days.

I have had the same problem

Has anyone talked to tmobile yet about this? I am almost to that point.

I too have been having this problem but I thought maybe it was just because of the iced glacier rom...glad to know in not alone...

Please post questions in Q&A section.

I have this issue with my phone I would be connected to HSPA with full bars and tried to watch a YouTube video using the app and after a min it would stop buffering. This got me really frustrated as it has happened quite a few times I called T-Mobile and they are sending me a replacement as we speak maybe you guys should do the same

Seems like a phone call is in order.

I've noticed this too, in the last couple of days. It happened yesterday and today as well. I wondered if it was an issue with the radio and some ppp problems, thankfully today while I was at work I noticed that my phone dropped its data connection and I asked my co-worker to lend me his phone (same model) and his had no data connection either. I live in the Miami area, my guess was that T-Mobile is either expanding heir hspa+ network or just messing with their antenas. Let's hope that everything goes back to normal tomorrow otherwise I will have to make a call and figure out whats going on!

I just got my phone late last night, and the 4g network has been disconnecting me every 5-10 mins.

Same problem here.

Glad to hear that I'm not alone.

This is odd. The disconnections only appeared on the first day. It has been fine since then.

Yeah, this was happening to me too. Up until recently, my connection would be intermittent in my apartment, but solid when I'm out on the town. Thankfully now tho, its always solid at my apt. They were Prolly working on the tower by my apt cuz I don't remember doing anything different.

sorry to bump such an old thread, but didn't want to start a new thread for the same thing.
I am having similar problems with varying degrees on several different mytouch 4g's belonging to me/friends/family.
The data connection drops out occasionally requiring a restart to fix; phone calls still work. On most occasions, my phone in particular, loses data connection while I'm on a call, but regains it after the call ends. Is there a fix for this?

Thank you for bringing this back up, I noticed this has been happening to me too, it will lose data. I'll still be able to text and call but no data. If I go to settings, it says "turning on mobile data" and it stays like that until I restart.

[Q] Wifi Issue

I looked around and could not find a thread about this.
I have a rooted fascinate with dl30 (froyo). Everything else is running fine.
But with Wifi on, my connection to the internet is fine until I stop using it. I have the wifi setting to never turn off.
But after about 5mins or so of leaving the phone alone my connection to the net seems to be lost. I will get no incoming emails, my connection to gtalk is halted. If I unlock the phone i can not pull up any webpages, gtalk is still disconnected and if i try to send an email it just sits there.
All of this remains that way until I turn wifi off and go to 3G. Then everything works again. If I turn wifi back on right after, everything works fine again and will continue to until I leave the phone alone for 5mins or so.
any thoughts?
If you have a thought but need more info from me feel free to ask.

Am I really the only one with this issue on this forum?

i just started getting this issue today.... i hope there is something that can be done.

I noticed it happening to me also. Very random though, only happens about once a day or less.

Same here.

Did it happen on 2.1? I am partly concerned because I ebayed the phone with 2.1 about 2 weeks ago. rooted, then installed froyo, so I didn't really get to see if it happened on 2.1, or if this is part of froyo. Was also concerned because a friend of mine, Nuance, also did the same thing, and came over to my house and had no wifi issues.

1.83 radio update bad?

Is anyone else having a issue with your phone having no service fir a split second causing your data to stop? It does NOT happen if im in a call but if im browsing it just stops and I have to.press refresh.

yeah not only dropping connections but almost unbearable. I'm in NJ and before the 1.8.3 update i could browse the internet fine with mutltiple tabs and so on. Wasn't slow then or fast but it worked. Now after 1.8.3 it just won't work, or will load half a page and break.
I've already tried using the old radio sbf file but that doesn't work with the 1.8.3 update...
anyone else?

I am having the same issue. I am browsing a web page and for a split second (literally, for a fraction of a second), I will not have data signal and the page will tell me either via a pop up that there is no data connection or it simply stops loading and I have to reload the page. Most of the time, I get the pop up saying there is no data connection, I press ok, and the web page continues to load as expected.
For further info, I flashed the 1.26 SBF and updated via the OTA updates. I use the stock browser.
I would say it happens once every 15 minutes of continuous web usage.
Edit: I have no additional problems with the calls or voice call quality.

I've noticed this as well, especially if wifi and/or bluetooth is turned on

This.
Also i was completely fine with the 1.26 and the 1.5xx system updates and could browse multiple pages just fine, however the 1.83 update seems to have borked everything even thought i'm still at work as any other day, so the location did not change.
I've also tried flashing the stock radio back (sbf) but it just doesn't work.
also no calls are dropped, and texts work fine, just data is borked.

I think the radio with the 1.8.3 update maybe the reason my battery life has tanked since the update. I use the same app and have all the same settings and am needing at least two batteries per day with the same level of use. I used to could listen to bluetooth with mixzing or winamp app. 6 hours per day, surf the web all I wanted and text heavily and still have 40% battery after 12 hours. Now after 4 hours of use I am regularly down to 30%. I seriously have checked and my use and settings are the same. I even have used spar parts and watch dog to monitor my app and system processes and I can't find anything out of the ordinary.
Is there a way to check to see if the phone is searching for 3G or HSPA more often and draining more battery?

Same thing happens to me guys. Data connection worked flawlessly on 1.2.6 and 1.5.7. Have sat on the phone (a different one) with att troubleshooting for an hour and they couldn't figure it out...eventually told me to do a factory reset even though I told them jihads already done so...big surprise didn't work. It only happens in certain areas and even then it works sometimes. My theory is it is something to do with how its handshaking with the towers, as I have gone into the service menu and seen it sporatically switch between UMTS and HSPA. Oh and I'm on gingerblur 3.5 but have done hours of testing on a stock flash of 1.8.3 and it has the same issue. Wish att /moto could figure this one out. Anyone find anything yet?

If your talking about constantly switching from (E)dge to (H)SPA I'm having the same issue..

Same here. Areas in which I used to have no trouble and good service now leave me with the no service icon.

Has anyone had better service changing to the 77 radio from .83
Sent from the bowels of hell...

I just wasted my time with AT&T by calling them. They told me it was probably a defect and I should exchange my phone.
This seems like a all too common isuue with this phone. I'm guessing the threshold at where it switches is just too finnikey. And whats most aggravating is we can't manually set which type of connection to use.

It's not even that it technically switches services from EDGE to HSPA (the icon always stays as an H), it's that when you go into the service menu it sporadically looks for UMTS (I think EDGE and 2G networks) and HSPA. You can try this out by going to dialer and hitting *#*#4636#*#* and going to Phone Information (it's under network type).
***Edit*** @the last post...I made the same mistake calling AT&T, and unfortunately that's an hour of my life of being talked down to and placated that I will never get back.

I was also having the same problem. I seem to have fixed mine by flashing back to 1.26 and ota back to 1.83.... First I backed up all of my apps. Sbf to 1.26, rooted with aroot, restored all apps, unrooted then ota 1.57 and 1.83. I have not rooted my phone yet but everything seems to work fine now.

That is actually one of the combinations I haven't tried, so if it get so bad as to be unbearable I may try that. Lately, though it hasn't been that bad thankfully.

[Q] EVO Shift: Data Call Failure after Temp-Root

Hey guys, I'm hoping somebody might be able to lend me a hand.
After applying the Temp-Root to my EVO Shift (GB, 2.3.3 (temp-root found here)), I'm getting the following error message:
Data Call Failure
Error Code 67: Unable to establish wireless data connection.
Has anybody seen this message? It comes up randomly it seems. I'm still able to connect to the internet via wireless. I'm not really sure what the deal is. It's similar to another one going around, but the other refers to the username/password. This one does not.
I have googled the error message, but almost everything I come across is a mass hysteria of confused people. I've tried the things I've found.
I haven't tried rebooting, yet, as that'll kill my temp-root (doesn't work in most cases anyhow, from what I've read). But, I'm willing to try it tonight if no other options are available. I've tried updating profile and prl, but issue remains. Not really interested in getting Sprint support involved, as from what I hear they're mostly a bunch of... uhm... funny people.
Any help is appreciated!
I should also note: This may have nothing at all to do with the Temp-Root. As far as I can remember, it worked fine for the first day (I applied it about 2 days ago, I think). However, I didn't do anything that day that required use of the Wireless connection (but wireless was still enabled).

i got that error once and just rebooted and retemprooted and havent gotten it again

As per my original post, I have already updated both profile and PRL. Thanks for the suggestion, just the same.
Edit: The problem may be due to billing issues. Will wait for that to get fixed and see if that fixes is. Will report back.
Another Edit: Does appear this is due to billing issues. Seems to be working just fine again, re-rooted and all.

Was getting this Error message for about a half a day a few weeks back. Updated PRL and Profile, didn't fix the issue. Called Sprint, turns out they were doing some work on the towers. Rebooted the phone and all was good. You might want to try and put the phone in Airplane mode for a few minutes. Then turn off Airplane mode, see if that helps.

I actually tried all of that. In my case it seemed to be a billing issue, because as soon as that was cleared up (the phone didn't have service, and I didn't realize til' I tried to make a call) everything worked fine... and has since. Thanks, though.

No problem, here to help when I can. Glad you got it sorted out.
