I've had my Xoom since the beginning of March and this is the first time I've had this issue.
Earlier today my 3G wasn't working. I go to my settings and try to turn off the mobile network and then turn it back on. That didn't work, so I restarted the tablet. Connects to 3G no problem.
I come back from lunch and the same thing happens. I go to the settings and try to turn off and back on the mobile network. No dice. Reboot, 3G is back.
What gives? Anyone having this problem? Running 3.1 not rooted.
Well, this is an old thread - but I was doing my due diligence by searching before posting a question and this is the closest I could find. In fact, it exactly describes my recent troubles. I had to power cycle my Xoom 4 times yesterday to restore data. Turning data off and back on didn't restore data. Only a power cycle resolves it, for a while...
I live in a 3G only area. I just got my Xoom back from Moto service, after it got stuck in the Honeycomb boot screen animation for the 4th time in 6 months. Since getting it back, I've had these data connection issues. It's strictly stock OS, by the way. Android version 3.2.6 and build HLK75H
If it did it daily, I'd say it's a tablet issue. But yesterday was full of reboots and today it's been fine all day. Sound like a known issue or perhaps just a Verizon data problem?
thanks all!
Well I had something similar but reboots didn't fix it. Sent mine in for the LTE upgrade and returned with signals barely 50% and not staying connected, in either LTE/cdma or cdma modes. I took mine to work and inspected under a scope and saw cold solder joints on all the antenna connectors for the center pin. Reflowed them all and signal strength back up and not dropping data. Not sure if this would apply to you.
Thanks, Tiger. I think my Xoom issue is different since, when I DO have data connection, the signal strength is fine. And reboots restore my connection.
I have discovered that I can force this to happen by leaving an area with wifi coverage. My Xoom now consistently won't transfer from wifi to 3G. As an experiment, I turned off wifi today and it's been fine all day - running only 3G. But, if I have wifi on the transition from wifi to mobile seems to choke it.
data issues too
Mine used to be just fine. After the 4g upgrade I am now having these same disconnect issues as well. Should have never let it out of my hands... I am thinking it is time to root and rom and hope it is a software issue.

Well what your describing sounds more like an app causing the problem. One of ur apps is holding onto the radio (wifi or cell) and is not letting go so the tab can switch properly. Since you sent it in for repair I would assume you made backup before it went in and you just restored it all. Which if the cause is not an app, then one of the system apps restored data conflicts with what's in there now.
If you used titanium backup I would perform a full back up, wipe your tab back to default state. At this point just give your tab a dry run (just skip sign in and adding accounts so google doesnt restore your apps) and use wifi/cell, browse web, for while to see if problem continues. If not then restore "missing apps and data". Not full restore. This way it only restores what's missing (which of course won't be the system apps/data). After this then things I would only restore in system apps would be browser favorites.

I like many followed the instructions on the Leaked 2.2 to install Froyo.
I performing the rooted instructions requiring me to upgrade to Baseband version and verify that it's 2.05.00.06.11. This went fine and I successfully installed 2.2.
I noticed that I was having real connectivity issues. My bars would drop and connection would seem to cease. I often went from 3g to 1x connectivity and my apps could not connect without a reboot.
I reverted back to 2.1 but it kept the same baseband version 2.05.00.06.11.
I am still having the same connectivity issues.
So far I have seen people suggest dialing *288 to update the towers but that didnt work.
Other say toggling airplane mode fixed it for them. This is not a consistent fix for me.
Please add information here so we can try and find a fix.
I updated mine to the leaked 2.2 yesterday and I did lose my 3G for a few hours. I started to troubleshoot afterwards and toggling airplane mode would restore my 3g connectivity. I haven't noticed anything else that is troublesome so far, however, I am also missing some apps in the market.

There is a fix for the market problem -
I am trying to keep this thread about the connectivity issues. I suspect the firmware update did something bad. I am not running any roms or updates.
I'll have to try toggling airplane mode, I haven't tried that.
Yeah, I'm having issues too, also video recording has stopped working.

Not real sure if this is the same problem or not, but i'll post it here and we'll see. My phone seemed to have ZERO issues yesterday after the move to 2.2. Everything was working great (related to connections)
This morning, my alarm (on the phone) went off at 6:15am and I swiped it and got up, went and took a shower. While I was coming out I heard "Droid..." and was like, well that sux, a random reboot. A couple minutes later I came over to it and it was on the lock screen and the screen was dim like it was about to turn back off. I touched it to swipe and it was locked up and rebooted a second or so later.
Each time it came up, I had an X next to my signal meter and no WIFI or Data indicators. The process "system" kept dying and eventually causing the phone to reboot. I tried going into airplane mode / coming back out, but nothing.
As a last resort (so I could go to work) was to shut it down gracefully (reboots wouldn't let me get to hboot). And go and do a nandroid of the current setup and restore to yesterday right after I switched to 2.2.
After the nandroid finished I went ahead and rebooted it w/o a restore. This time the phone booted normally, no FC's and it's been running since then w/o any connection/reboot issues.
Obviously I'll be paying attention to this. It is actually nice having the "Droid..." so I know when it reboots

I havent had issue with the system process dying and rebooting. Just the incredibly annoying fluctuations in the bars and connectivity.
I would go to use my gTalk or gMail and it would say no internet connection. Or if you open the browser. Same thing.

No data
I updated the radio as well as the leaked 2.2 ROM. I now can't get any data. It will say there is a 3G connection but the market, Gmail, browser won't work. I was previously able to get data I haven't changed anything since.
I thought my data issue was using the Hybrid Altell/VZW prl, but after a *228 option 2 I am still having an issue. It seems to be when I shutdown the phone, turn it back on, the mobile data connection will not turn on. Toggling airplane mode will fix it, or sometimes a reboot fixes it.
Also having 3g/1x/no data issues post update to 2.2
Upgraded 8PM last night, all good until about 10am this morning, realized none of my apps were sync'd, then tried to use Opera/Market/Etc. all saying connectivity issues. The airplane mode on/off seems to fix it, wondering if its a select few and we should reflash or people are experiencing this across the board...

I had nearly the exact same thing happen to me. Flashed last night and then noticed the problem early today. A reboot of my phone fixed things; I'll continue to watch things closely.
Just got this for the first time as well.
I was just doing some configuration and needed to reboot - after doing so I did not have 3G and mobile network was ON in the settings.
Toggled to airplane mode and restarded - switched back after startup and 3G is back... but still this is troubling (I don't want there to be ANY problems haha)

I am trying SkyRaiders rom to see if theres any improvements. I am on WiFi and its been working good so far. I will know more tomorrow.
Are you just getting the slow downs/disconnects on cell or also on WiFi? I had some weird WiFi issues last night so I thought it was both. Are you all getting it on all data connections or just the mobile network?
Make sure System Select in Mobile Network settings is on Home Only. I did this and I've had zero data connectivity issues with the leak. Had them when it was on Automatic.
Try it out.
I will join in and say I am also loosing 3G...it would be fine for a little then disappear for a while...toggling wifi and airplane mode helps, but I want it fixed and not have to rely on those.
Seems that Sky Raiders Rom has fixed the issues for me.

Which version? I am using 2.00 and I am having 3G connectivity issues. When I set my mobile networks from automatic to home, I only connect at 1X instead of 3G.
Is this fixed in Sky Raider 2.01?
UPDATE: I should have stated my original problem which was my 3G data connection was shutting down at random and the only way to get it back was to go in and out of airplane mode. I also JUST NOW updated to Sky Raider 2.01 and see that I don't have and data connection at present. A reboot did not work either. I'll keep trying things...
UPDATE2: Got it working...for some reason it was turned off in settings. Appears to be working fine now. I haven't seen any disconnects yet. Fingers crossed...
UPDATE3: It started doing it again under Sky Raider version 2.01. Don't know whether it's the new v2 radio or something with Froyo...

It is beginning to look like maybe this is a radio (2.05.00.06.11) problem an not a OS issue. But what I don't understand is why more people have not complained. I do live in a fringe signal area for 3G, perhaps that has something to do with triggering this problem. But I too have found that toggling airplane mode isn't a consistent fix.
If this is indeed a radio issue, then we may have to just live with it until a new radio version is released. Perhaps it would help if more people came forward and shared their experiences about this alleged problem. If it is only a few of us, then what might we have in common???

See here, 99% sure has to do with WiFi. I've been turning off WiFi before I leave the WiFi area I'm connected to and I've yet to loose data connectivity.
If this is all there is, I have a fully working 2.2 on my DInc now...don't really see a reason to upgrade to the official!

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.
i have a variation on the data network problems, not as annoying as reboots,
but getting close.
normally i am on GSM only, as my data needs are low and it extends
battery life. for hours, everything is dandy. then i notice that
the "G" icon and the signal bar are not blue anymore (stock theme)
but grey. 'settings' say i am still data "connected", but in fact
data connection is out (the operating system thinks there is
data connection, browsers and mail clients keep spinning and
trying until timeout).
turning on and off wifi makes the phone try to connect to the data
network again. sometimes this works, but more often that not, i have
to switch to 3G mode for this to work, and sometimes even that does
not help, and i have to go airplane mode to turn the radio on and off
completely. otherwise it just tries and tries and tries to reconnect,
draining the battery like crazy, and sometimes resulting in these
mysterious reboots others are experiencing as well.
is this the phone or a network problem? (tmobile in the netherlands)
i was on the same network, same SIM with an older LG android phone
and i dont recall having this problem, so i am a bit hesitant
to blame the network for every outage...
should i just send it back for repairs/replacement?
system version: 45.0.74.MB526.Retail.en.DE
baseband: EPU93_U_00.60.00
for a while i will keep the phone in 3G mode to see if the same
problem exists. as my mobile data needs are low, it would be
a shame if i cannot keep it in GSM mode because of this...
I had the same problem couple of months back but since I'm on msginger don't have that enjoying problem anymore.
Ohh and as far as remember it was only when the battery was on maximum save, now I'm using custom and it's fine

i am on custom saving mode. i think that the saving modes, where
the data connection is cut off after some inactivity, just flesh out
the problem more, as trying to connect back to the data network
happens more often then during normal use, when data connection
is kept alive all the time.
since i set the connection mode to 3G or better, i did not have the problem
but that was only a couple of hours ago. sometimes a day goes by
without manifesting itself...
I'm on 2G all the time. And the custom saving still got set up for cutting the data off but i don't seem to have that problem anymore i can check later on if it would still appear on max saving.
Sent from my MB525 using XDA Premium App
so after days, it seems like i cannot reproduce these problems
while on 3G. seems like 2G only for data is not 100% reliable
either because of the phone or the network itself, or both.

i m having problems with network reception with the 7.2 CM rom on the defy+.tried the baseband switcher in this link but still little or no reception
http://forum.xda-developers.com/showthread.php?t=1203297
i have been on 3G last couple of days, and no data woes.
however i had a spontaneous reboot, so the reboot problem
is seemingly not only a 2G issue (if it is)..
I'm having a problem with my N900W8 since doing the Kitkat upgrade.
On Jellybean, I can be in a building, unable to get LTE, but have strong 3G/HSPA+ connection and it works great.
Ever since upgrading to Kitkat though, while LTE continues to work great, if not faster in my speed tests, when on 3G/HSPA+, after a short while, the data connection seems to freeze. I'll see it drop from H+ to 3G in the menu bar, and just merely a flashing up arrow, and nothing else. It never seems to fix itself, and I just have to put the device to sleep by tapping the power button. Within a minute it regains a good data connection again for maybe another 2 minutes. This is constant.
I'm at a loss, it's a new phone and only had it for 2 months. It's not rooted or anything like that, just unlocked by the distributor, and on T-Mobile (if that matters).
It's getting annoying because it makes using my data connection completely unusable. Samsung techs were actually quite helpless, they wanted me to send in my phone, but it seems to be software related because it worked fine on Jelly bean. It literally happened RIGHT away after the kitkat upgrade.
Please someone help? I already have checked, double checked, triple checked the APN settings, even deleting them and starting over, and trying both fast and epc APN's on T-Mobile.
I reset the device back to factory, and all was well. And I noticed that it started happening again after running the speedtest.net app on the 3G.. It seems to start doing it again when I run that app, and when I "cleared" all the app cache, the problem seemed to go away. Not sure then what's going on there.
I need help this is driving me insane!
I've been running Dynamic Kat Rom for about 6 months or so now. Everything was working fine then all of a sudden a week or two ago I noticed my mobile data is not enabling at all.
I can only connect on Wifi and only receive SMS.
I've tried
- Messing will all the data/network settings
- Turning Mobile Data on and off -- no effect
- Toggling Airplane Mode on and off as suggested in some places
- Wiping everything but Data and reflashing latest ROM
- Reseating the SIM card
- several other things I forgot..
I do see the carrier information in the top left (AT&T) and I am getting signal bars.. but not indicator for 4G/LTE/etc
I've been messing with this for a week now and it's driving me insane.. I can't get a connection anywhere unless I'm on Wifi.
Anyone have any suggestions? I'm not super phone savvy, but willing to try any suggestions anyone may have.
Hmmm.. weird.
So I called AT&T and asked them about it.. figuring it could possibly be a carrier issue.
They told me to try things I had already done 100 times.. turn the phone off and on.. turn wifi off... etc.
I turned Wifi off... (which I had done 50,000 times before) and 4G popped up.
I guess they did something. So.. guess it's resolved.
Problem has returned.. same issue. I will have 4G signal for hours and then all of a sudden it will drop completely and I can't get a data signal no matter what I do.
I see AT&T in the corner and have signal bars, so I AM getting some kind of signal.. but no data connection whatsoever.
It seems completely random and intermittent.. I can have data signal for days with no issues then I will lose it for days.
Restarting the phone 5-20 times sometimes fixes it.. but that's about it. Anyone have any ideas what could be causing this?
Bad signal / carrier issue?
Call them and report a fault in your area?
I have called them multiple times, they will reset the signal.. sometimes it will come back right away, sometimes it wont.
And this happens regardless of where I am. I know for a fact where I am right now has a great signal strength. I get 4-5 bars on average. But this also happens at home as well about 20 miles away, which also has a good signal, or anywhere I go really it can happen. This isn't in the middle of nowhere either, it's smack in the middle of SoCal (LA/OC)
I'm beginning to think it may be a SIM card issue or a hardware issue with the phone. I'm going to try asking them to send me a new SIM card.
Another thing I will notice is when I have a working 4G LTE connection, and I'm on Wifi... it will sometimes CONSTANTLY switch back and forth between wifi and 4G like every 10 seconds, even when I have full signal strength on Wifi and 4G.
Disable Smart Network Switching in WiFi settings
it's nothing but a buggy headache, disabling might fix most of your problems, almost certainly the constant switching back and forth
Yeah forgot to mention I have disabled that. It's disabled now. It solves the constant switching back and forth (when I actually have a data connection), but that's kind of a separate issue as the losing data connection.
