Data connection dropped for no reason

This is starting to bug me..... for no reason the 4g connection and even when I turn off the mobile network, wait a few minutes and turn it back on, it still wont work until I reboot the phone. Sometimes rebooting it doesn't work and I have to pull the battery.
Anyone know whats causing this? When this is happening I see the ^ arrow on the 4g connection lit up like a christmas tree but nothing is uploading and theres no data connection....... HELP!

Mine dropped Last night for the first time. When I first got the phone it flip from 3g to 4g at my job. Last night finally went dead. I rebooted and still no network. Then I used the new LTE switch to keep it @3g only. It worked.

Where do you get the LTE switch?
I have seen it step down to 3g and back up to 4g LTE but its just sometimes 4g just chokes for no reason......

Surprise u didn't hear about it. Its a free app. If it was a paid app it would sell like hot bread. Check the market. I can't post a link yet since I'm brand new to the site

same issue with mine in Denver

You also go to your dialer and type in *#*#4636#*#* to get to the menu.

same issue here Philadelphia sub
when i bought the phone, it is very easy to get 4G in my home and work
and recently, I only can get 3G in home and 1x in work.
and it is not stable, very easy to drop.

Yea sometimes 4g just hangs and it wont step down to 3g...... forcing me to reboot or hard reset .....

Hey Stoneskin,
I live in Hawaii and I have the very same issue as well. I picked up 4g easily in the "so called" extended 4g coverage region when I first got the TB. Then about the middle of last week, poof, no more 4g except for in the true 4g areas. My thought is because so many people were having 4g connectivity issues in these extended area, VZW simply stopped allowing it as a troubleshooting measure that apparently is still going on. I brought this up to VZW tech support and they were clueless as usual. I also posted in the VZW Community Forum hoping to get an answer, but none thus far.

you could try dialing ##778# and pressing send, select edit mode, password is 000000 and then under modem settings change it to rev A. then press the menu button to save and reboot. it has helped me out in the El paso area. friend showed it to me the other day Far as i can tell is that it disables the new network that allows voice and data at the same time since that's the only difference i have noticed other than not loosing my connection anymore. I just a heads up this does not work on the latest version of virus rom RC1B3 sensless but did with previous version and several other roms i had tried

Thanks for the tip, but it didn't work. VZW must have changed something to where extended coverage area no longer get 4g. Only those in true 4g areas. I really think this has a lot to do with the folks experiencing the constant drop 4g issues. They must have rationalized that if the extended area for 4g is not up to par and forcing 3g would be better. Only way I can explain it. From consistent 4g to only 3g. I sure miss the speeds.

Constant data drops

So I am currently running bamf 1.6.3 and I change kernals a lot, but one thing I can't seem to fix are the data drops. I live in raleigh, so no LTE, and am running the .7 cdma / .6 LTE radio combo. The data drops off a lot, more noticeable when changing towers. Even sitting at home with good signal it will just drop to 1x and is hard to get 3g back without a reboot. Anybody else see this? No reboot problems

So am I the only one with this issue??

Mine drops 3g and 4g for a second or two and then comes back. It has been happening a lot recently.

At one point in time I would have that happen, it was because of a local tower being screwed up. Maybe switch from eHRPD to the standard 3g network? or vice versa?

Had the same issue with 1.6.3 and went back to 1.6.1 and Im fine again. Ill wait for another version before updating again

Having this same problem but I'm on stock and it only happens while I'm on 3G....nothing but problem since I got this phone....did Verizon and HTC test this phone out? Gps problems,reboot problems,data problems,battery...I'm really sorry I left my carrier for this phone.

the NEW 4g network is going to take some time to get running properly and because of that will have issues as will the phones. Not everything works flawlessly off the bat, give time to get everything settled and figured out and it will get perfected.
With all the radio/prl updates they have been doing I wouldnt be suprised if it is caused from that.

I was having the same problem. Disabling eHRPD has seemed to fix it. I still see strange signal drops, but I'm not seeing data drops at all.

It's not a fix, but rather than rebooting, just turn on airplane mode, wait for the airplane icon to appear, and then disable airplane mode. I have the same issue you describe, so I just keep the airplane mode toggle widget on my second home screen panel.
I'm getting very frustrated with the inconsistent data connection on this phone. I halfway considered trying to get VZW to let me swap it for the Droid X 2 when it releases next week.

I have similar problem. I live in Northern CA with 4G coverage. The problem will be like this:
- 4G works OK, data works
- Moments later, 4G icon shown upload activity (arrow up sign)
- Shortly afterwards, no data. Mail, Google Maps, etc. failed
Fix is to turn Airplane mode OR REBOOT the phone. I have tried switching radio mode (using LTE ON/OFF) but to no avail.
I understand 4G is new and so is the phone, but c'mon.. it has been sometime now and we are STILL paying for the service, even when the 4G network is down (few weeks ago) or when the phone loses data.

This happens to me on stock. Will be using 4G and then all data drops, then comes back, then drops, then comes back and repeats the cycle. Rebooting, airplane mode, nothing helps. Eventually it goes back to normal.

My phone went wacky yesterday. 1x and no data for four hours. Spent an hour on the phone with Verizon tech. We did everything possible and nothing. Then it just fixed itself. Had someone with a Droid X in the same room as me with great EV signal. Now the phone is perfect again. I dont get it . I have enabled REV A and now I put it back and that didnt matter.

Mine as well on 1.6.3 bamf remix. i had to keep going in airplane mode. it was stuck on no service or even the 4g icon (not blinking and no service)

We are Guenna pigs....

Since i have gone to the new leaked gingerbread radio not the latest froyo radio but the new gingerbread i dont have data drops
get it here http://www.multiupload.com/KQCRTNALV9

I too had continual problems with data yesterday (on BAMF 1.6.3) in San Diego. Kept switching from 4G/3G/1x. Today seems to be running smooth.

I'm gonna say thank god I'm not the only one, I don't live in a 4g area, yet there's many times my 3g will do the same arrow thing showing up and than everything fails. I'm running the new radio and perfect storm 1.4
, and drods kernel

In NYC and stuck at 1X?

Hello all,
This has been happening to me for about an hour now. I'm typically in good, constant 4G range. Is anyone else having data issues?

i found this: http://www.howardforums.com/showthread.php/1718601-Data-outage-in-Nassau-County-and-Manhattan
dunno how close that is to you but maybe it's not just you.

seems to be back now... let's see how long it lasts, lol

i dont even have 1X...around 2:30 PM went into a subway, turned on airplane mode...once i got out and put my phone back on....no data since...even now still.

I'm in north jersey about 45 mins from times square and i'm on 1x for over an hour now. Hope it's the network and not my phone haha. Sigh.

I was having issues with weak/terrible 4g in my area a few weeks ago. (lafayette Indiana) It was kind of an ongoing thing for awhile, but come to find out that verizon was actually working on the network to expand it across the entire city. Just what was going on in my area and possibly in yours.

just did a wipe on my phone...still no data.
my last resort maybe try different froyo radios? or wait??

No go with Froyo either... I am working out of our madison ave office for the day and I am stuck at 1X. I flashed back to Froyo in hopes to get data, but nothing.
EDIT: I just went down to the verizon store that we have on the street and their Charge has 4G, but their Thunderbolt has 1X...

waiting it is...thanks for the info

I still have 4G now... it seems to be working ok.

Just had this same issue in Detroit. Was stuck on 1x for a couple hours. Tried restoring a few backups, rebooting, and factory-resetting + clean flash of BAMF, but none of that worked. It just came back up a couple minutes ago without me touching anything. My guess is VZW is making some adjustments.

Don't know if you were running gb or not, however, I ended up frying my sim card shortly after reverting to froyo. Just FYI. I had the same 1x issues.

I had 4g early in the day yesterday. I switched to 3g, and when i tried going back to 4g i got stuck on 1x ever since. 3g still works but if i try to get 4g i only get 1x.

if the sim card is done wouldnt you get no service at all, not just no data?

Aroiund midnight into the early morning is when VZW does upgrades/work/testing/etc... on their network. Most people are sleeping then, so they do it then, because that is when it will effect their customers the least.

my data finally came back!
i probably could of waited and this be a coincidence...but i turned off the phone, pulled the sim card, turned on the phone to let it tell me "no sim detected" then turned off and put sim back, booted up and i'm good again. whew.
edit: after boot, loaded a web browser, the 4G icon disappeared and my homepage wouldnt load =( UGH

I've had LTE all day (since about 7:30 AM this morning) so my hope is that they are going to do maintenance and restore LTE to my home area (have it strong at work...but they took it away from my house a few weeks ago.) I'm in the Lehigh Valley, PA.

I'm in Manhattan in the Flatiron area and the UES and have been on 4G all day. I'm on Froyo (BAMF Stripped) with the leaked radio fwiw.

I just tried this and it worked for me. Hopefully it sticks.

Had total data shut down last weekend in Brooklyn
It's fine now though.
Was able to hit 38mbps down after I got my 4G back

4g down or buggered phone?

Im in the DC area and my phone wont connect to 4g for life of me (im in a strong 4g area). tried toggling. tried forcing LTE only(either 1x shows up or nothing at all). tried turning off data for 10 minutes. tried removing battery. tried full wipe (wiped three times cache, tried clearing davlik cache and battery stats...three times) reinstalling 1.7. I can still connect to 3g and 1x. Just no 4g
i was initially on bamf's 2.0b5 and noticed i couldnt get 4g. so i restored back to 1.7 and still no 4g. and no i didnt forget to flash the appropriate radios. i called verizon to see if there were issues with the network in the area and they came up with nothing. is my radio broken or am i missing something here?

Try starting the phone up once without the sim card in and then reinstall the sim card and see if it works.

just tried that. no dice. any other suggestions?

Maybe take it in to vzw and have them test the sim. It could be fried.

whoa. i didnt know that could happen.

same thing with mine I am in Manasasso area and i get 4g off and on but cant get on the market or google, then i back to 1x so is it a phone issue or a system issue.

Well with me its not even on and off. I get nothing at all.
Sent from my ADR6400L using XDA App

I'm sure this is a stupid question but it must be asked. Do you have the back of the phone off?

no such thing as a dumb question. just dumb people. hahaha im kidding. just trying to make light of the situation a little at least. i had a teacher that would always joke around like that so i had to say it.
but i digress, no the battery cover is not off. like i said, 3g and 1x works. just no 4g. can it be possible that just the 4g radio could be broken or if that were the case, i wouldnt have any data network at all?......
and as i was typing this message, my 4g connection had just connected. i think it has to do with the area where i live because I am now in my work building and it seems to be working fine now...i guess verizon lied to me... thanks for the suggestions. will post if things change.

Well, according to Verizon and their coverage map I'm supposed to get 4G at my house but I don't. Granted, I am on the edge. Now, here at work is a different story...solid 4G and it never looks for 3G.

Yeah, I am supposed to have 4g at where I live too. And I would get a strong signal too, which was why I was totally stumped when i couldnt get a 4g connection all of a sudden and verizon told me there were no problems with the network in the area.

this is happening to me as well. Phone keeps jumping between 1X and 3G all the time. I rarely get 4G anymore
I'm on Perfect Storm1.5 running the MR2.5 Radio chingy leaked
I have tried 4 different radios as well as ROMs over this past week, no change on either

been 4 hours and phone hasnt dropped 4g since. even flashed back to bamf 2.0b6. I would get no signal on reboot, but toggling works like usual again. i guess where I live is having problems right now. will post when i get back.

working now. im guessing its the network. running 2.0b6 with mr2.5

This was happening to me as well. I would sometime get "4G", but it's fake 4G, as I would not be able to receive any downstream data, and connectivity would soon cut out. I've gone from GingerRemix 2.1 back -> 1.7 -> 1.63 -> stock -> stock unrooted, and could not get 4G back.
I decided to throw in the towel and go to Verizon (with GingerRemix 2.1 loaded), to compare. They definitely had 4G in store while I was carrying 3G around. I told the "device specialist", and without much questions, he popped in a new sim card for me. I had 4G then until I was about 4 steps out the door, and it would fall back to 3G. The dude and I spent the next hour swapping out another card, placing my sim card into a returned TBolt, but no luck. Finally, he did a factory reset on my phone. With no further luck, he resorted to ordering me a new one.
Still unsure what the issue is since he did give me a new SIM, and that SIM didn't work on another TBolt as well. We'll see whether the new one that comes in the mail tomorrow will fix the issue. I've since then reverted back to stock, since I need to mail my "broken" phone back to VZ, still no 4G.

[Q] Nexus S 4G - DATA DROPS

I have been having this problem with both of my Nexus S 4G ever since I got them 2 months ago.
My data drops out frequently and takes a while to get back up. If I have 4G enabled, then I have to manually reconnect it as it will not do it on it's own. This happens inside AND outside. Driving down the road or just standing in one spot.
I've tried all of the radios (basebands) and about 7 different ROMs and versions.
I've refreshed the data profile, PRL, and even tried the roaming Verizon PRL and Hybrid PRL.
Gone back to stock and tried everything from scratch. Still the same problem.
Dallas/Fort Worth Area
Network: Sprint
Baseband: D720SPRKE1
PRL Version: P:40447
I contacted Sprint and they just told me to update the profile & PRL.....
Any suggestions?

I'm not familiar with the CDMA nexus s, but are you able to change APN's? At one point I'd be able to connect to 3g (I have an I9020A), but every minute or so it would drop, so I fixed up the APN's for my carrier.

iv had a few data issues
forcing PRL and account updates has fixed it a couple of times
i'v bought used phones that iv had
to have sprint force update
im on LC1
[altho i cant tell any significant difference here]
and my prl is 61086
[a business account]
im currently on slim
make sure your mobile network
is set to roam
is not set to home only

Am I the only one with this problem? As I'm typing this I lost data but still had 3 bars. I never drop calls but only data.
Help please. This is driving me nuts.

no
i go thru periods of it acting bizarre
try disabling wifi and reboot
this USUALLY fixes mine till wifi is re-enabled
and i drop the sprint connection a few times
riding around
it then fails to re-acquire the IP address.
look in your status and see if you still have an IP
when your data fails
fwiw

I never use Wi-Fi. Ever.
Happens while using both 3G and 4G.

4G is worthless here...
i dont even bother with the switch
does it do the same thing if you disable 4G?

I almost always have to use 4G (if possible) since 3G speeds are slower than dial-up.
I've tried rebooting and leaving 4G off, and still the same. Even tried going back to Gingerbread.

In the original post, I stated that was one of the things I've done.

have you checked to see if you have an IP address
when data fails?
mine shows "unavailable" when it's wonky

I have the same problems. From what I understand, its a problem with the hardware. I can confirm that's probably the case, because I've tried many different ROMs (stock, cm, etc...) and they all have the same radio issues (3g/4g and wifi)...

I have an NS4G in the DFW area and haven't seen the issues you're reporting. I'm currently on 4.0.4 with D720SPRLC1 baseband. Maybe I'm just lucky and have a good signal at work and home. It's very rare that I find an area of DFW where I don't get any data signal at all. Not sure what to suggest.

I get random drops too and i hate it. My 3g speeds are fairly good even above 1 mbps. Highest i ever got on 3g was 1.51 mbps

Mine will lose data if I'm in a coverage free area for an extended period of time, when I'm back in range 3g icon will show up just never reconnect. A reboot fixes it

Certain Areas
There are certain areas where I live that data just disappears. Although this is just a network thing I believe. It's weird though when I am driving it's like a 10 second drop and then all is good. Hope you get a solid fix!:victory:

Backup 4g Partition
REMOVED - was a bad idea.

I've actually replaced BOTH of the phones with brand new NS4Gs and they shipped with ICS.
Still the same problem.
This is driving me nuts. I was driving and trying to download Maps for the new phone from the Play Store and it took 6 tries. Kept saying RETRY.
What I've come to believe is happening is:
When 4G connects, 3G disconnects. When 4G drops (which is does frequently), 3G has to reconnect.
***Is there a way to keep 3G "on" in the background while 4G is connected?*** Maybe a way for the radio to transition back and forth?
