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.

4G Problem

I'm having a problem where my phone will not connect to 4G, it connected fine for about 2 weeks and then it stopped working. I have tried everything I can think of, restores, data wipes, new roms, the new radio, messing with modem settings, but I have had no luck, I'm starting to think that it is just my Thunderbolt and I will have to get a replacement I took this screenshot of the thing i think is werid, the phone recognizes the LTE network but GPRS service is disconnected. If anybody has any suggestions on something for me to try it would be greatly appreciated. Thanks

Flash the new radio that was made available today and see if that changes it. If not factory reset your phone and bring it in and say it stopped working.

I been have problems with 4G since Saturday here in San Diego. It has been working fine for 3 weeks up to this point. I have 3-4 bars of 4G, but there's no network connection. The connection does NOT bounce between 3G/1X. It is solid 4G, however on the 4G LTE icon at the top, only the white arrow lights up, never the down arrow. When I run the ping test in the diag screen you posted there, it fails.
I went down to the Verizon store near my house and they had two display Thunderbolts. One of them was having the same exact problem as mine. While I was there, I rebooted mine and it magically started working right.
Then about a hour ago, it stopped working again. Rebooted twice and nothing. Called Verizon tech support just to let them know there might be an issue since my phone and the display phone werent working right. They transferred me to a
"4G specialist" who had me shutdown the phone while he "rebuilt" my account in their system. Booted back up and it works again.. Dont know if something he did fixed it, or the third reboot fixed it.
BTW, my phone is factory stock. Have it set to LTE/CDMA Auto in th phone settings.

Sigh... it's doing it again this morning

Same here, stuck using 3G until further notice.

Ya this problem is making me mad, I'm going on a trip, and when I get back if I still have problems I will just unroot and get a replacement, I really hope someone knows a fix to this though and posts it

My 4g and 3g have been on the outs today here in ohio. Never had the issue before today. I'm assuming its a network issue and not an issue with my phone. And I have the new radio fyi.

-89 dB is pretty weak. -89 to -93 is what mine is at most places in my house. The only way it will go from 3G to 4G is if I walk over to the bedroom window facing the nearest celltower and then it will go to about -78 and switch to 4G.
When facing the tower do not "cup" the phone because I have seen as much as 10dB loss from my hand being between the phone and the tower.

I can say the same thing in Phoenix.... you have good 4g days and you have bad 4g days. Like yesterday... up then down then up then down then nothing for an hr.... then up and down... an awesome way to tank the battery.
I wish Big Red would make up their minds... and fix these issues.

Same here in scottsdale, shows the 4g icon but there is no data till it switches back to 3g. Maybe just a coincidence but mine started yesterday after upgrading to the new radio and bamf 1.5

I'm having the same exact problem you are having in NYC and now in Boston while I am on vacation. If I force the phone to 3G, everything works beautifully, but to get 4G working again, I have to power off and on the phone.
Now, while in Boston, this issue happens when I am in an area of no cell signal (say the parking garage of my hotel) and then walk into an area with cell signal. I'll wake my phone from standby and will not see the 4G symbol, and then the symbol appears, but no data, like what you described.
I wonder if it has to deal with how the phone connects to the towers. Maybe the new radio will fix it? I'm currently on stock since it's still runs pretty damn well.
Just to mention, my phone does not suffer from the cycling issue between 3G and 4G.

Switched to bamf remix 1.5 with the same updated radio and 4g works great now. Kinda like the remix better.. win win

Did you try taking out your batter and sim card... waiting a minute and then putting them back in? I had this problem once where I was stuck in 3G in a 4G area and this is what tech support had me do. I didn't think it would work, but it did!

[Q] Desire s stuck on gsm only

Hi there,
Hopefully someone can help because my brain is melting here. Basically I spoke to orange customer services the other day because of totally poor signal. He told me to switch to GSM only, which was fine and I know it can improve your phone signal. The thing is, it's now stuck on there, whenever I try to change it to WCDMA it automatically switches back to GSM?
Any body got any ideas?
Cheers
Ian

I feel your pain. I am also a long-suffering Orange customer. Everything was fine until they climb into bed with T-Mobile. Since then my signal has been so erratic I simply can't trust things like Google Maps to work as navigation. Orange have left me stranded twice bombing out the 3G just as I need it to get home.
Anyway, how exactly did you switch to GSM only? There are a couple of ways of doing it.
Menu> Settings> Wireless & Networks> Mobile Networks> Network Mode = GSM/WCDMA auto.
I suspect it was this one. If this is the method that is changing back to GSM, then try this one;
Open you dialer, and dial *#*#4636#*#*
This will open a hidden testing menu, from this select 'Phone Information'
Scroll to the bottom and see what the 'Set Preferred network type:' is set to.
Mine works well with both GSM auto (PRL) and GSM/CDMA auto (PRL)
See if selecting one of these helps.
Let me know how this goes.

Hiya mate,
Yeah I gave that a try earlier. It seems I have to either have a good phone signal or crap data and vice versa? Pain in the ass. Orange told me that it was because of a faulty telephone mast in my area that has been off since last week. Can't see that being right to be honest, since my signal has been ****e since I first got it in April. Thing is, my sister was having the same problem with poor signal, and she wrote to some higher up person at orange to tell them about it. It ended up with her getting out her 2 year contract, bonus! I'm just going to ring and keep complaining and then write to this person my self, and hopefully I can get out of it my self. Orange is the worst network I have been on!
Cheers for your reply

I might give that a try. I still have a year left, but would love to jump ship and move back to Vodafone. I only went with Orange as my girlfriend was on Orange and magic numbers meant free calls. She then went and screwed things up by moving in! Now I don't need to ring her so much! (facepalm)
My housing estate has a dirty great big cell tower mast at the top of it. My fillings could receive a text message. But even with max strength signal still the 3G is off and on so erratically it's not worth using. They keep telling me that "the cell tower in my area is being worked on" too. That's been their excuse since February.
I have no idea I'm afraid why your phone wont stay on a WCDMA setting however. How are your APN settings? Mine once roamed to T-Mobile without me noticing and would only do 2G.

Yeah my girlfriend is my magic number too, and I live with her as well.. Doesn't make a great deal of sense really does it?
I think you may be on to something with that tmobile thing. Does tmobile allow wcdma?

When I used to do a manual scan for other Networks the following would show up;
Orange
Orange 3G
T-Mobile
T-Mobile 3G
If I try to connect to T-Mobile 3G it wont let me. The one that is just 'T-Mobile' doesn't have anything more than 2G. What happened was my Orange signal dropped out, so it jumped onto the 'T-Mobile' one without me noticing. It then didn't go back to the Orange 3G when I got home.
I just tried it again and got;
Orange
T-Mobile UK
The 2G/3G variants seem to have been dropped and merged into a single provider for each network. I can connect to T-Mobile but still only seem to get 2G.
See which one your connected to. It might be that although we are allowed to use T-Mobile for calls/texts the deal doesn't include 3G.

Yip, that's exactly it mate. I go on tmobile and I can get only 2g, I connect to orange and it let's me have 3G. It jumps between the two networks, and as I have poor orange signal all the time it auto jumps to tmobile! So basically it looks like I'm stuck to 2g if I want to actually speak to anyone! At least now I know what the problem is, but it still doesn't make me feel any better about having to make the choice, and having to constantly check which network I'm on before knowing why I'm getting either poor 2g or poor phone signal. What a headache!
Cheers for your help, much appreciated!

Lately, I've noticed some **** with o2 as well which as I previously recall always had good service, since I been with them for as far as I can remember. I'll have full 2G signal, and randomly the data will shut off. Sometimes for a few minutes, sometimes for hours. But the phone signal remains on full... it's weird. And 3G coverage seems to be getting worse instead of better. None of this makes sense either since in March o2 apparently rolled out 900 Mhz 3G across most major UK cities, meaning 3G service on a 2G band, meaning much better 3G service in areas where only 2G service was previously good. I ain't seen **** all of an improvement, like I said it seems to be going the opposite way.
UK used to be ahead of the game when it came to cell networks, it seems most other countries have not only caught up, but jumped miles ahead. 4G is pretty standard in the US now, and they were so far behind in cell networks only a few years ago.

Is EDGE usable for someone?

Already stated in another thread, I have an issue when using EDGE connectivity.
(HOME button activate on its own and loop)
Can you please feedback here if you have the same issue and also if you use EDGE with no problem?
I was planning to return the phone, but in fact I didn't find any positive feedback...
My HTC One S is running under 1.78 EU

Works fine here. No problems when connected with EDGE and pretty good data speeds for 2G.
Also running 1.78 EU stock.

Hello
I've the same issue. no problem in G, 3G, H or wifi
I'm in Martinique. Phone received from France on wednesday 9th and updated to 1.78.401.2
I don't know if it's because of the update.
I contacted HTC customer service on friday. waiting for answer...

Yeah - same problems with the random and annoying home button activations when connected over EDGE - all OK on other radios...
"Fixed" it by setting my mobile data "Network Mode" to WCDMA only - which seems to disable the EDGE radio - I know this is limiting me to only using data where I've got a 3G signal or WiFi, but at least the phone doesn't keep returning to home...
Not ideal, but it definitely appears to be specific to when the phone is using the EDGE radio.

I've returned mine to the supplier but they didn't tell me if they solved the problem and just lost the phone when sending it back to me. I live in south of France and it was delivered near Paris. Thanks B&You for such a perf :-(
I can't get any news from them. I'm really disapointed by HTC to deliver such phones and annoyed now by the lack of respect of B&You(Bouygues Telecom)...
I'm back on my Defy that is broken(audio not working anymore...it's a PDA but not a phone anymore...)

Hi!
Right now (Subway) on EDGE and Home Button is working as it should!

Sent from my HTC VLE_U using XDA

I am using EDGE now it seems to be alright for the most part.

I have the same problem, I reported to HTC, I hope they fix that problem soon.
Phone is unusable for me most time I'm only in EDGE coverage in my work and home

it seems as if the phone is having trouble being a phone - all other features are great!
really, all phone related connections are very bad:
if it gets 3G it is hard for the system to switch down to 2G when necessary (used to be smooth with my desire).
System reports signal but actually I'm unavailable for long periods - didn't happen with my desire with same provider and same locations.

On EDGE it's mostly usable, but on GSM i have massive problems. Mostly if i enable Data connectivity in GSM mode. Also in phone mode in GSM i have always the homescreen toggle problem.
I contacted HTC, they say its a known error, and they are working on a fix, but have no release date.

My experience may not compatible to you.
Mine is in China mobile's EDGE network, which is using 1.54's radio.
the data connection(the "E" icon) has a big chance to be lost when switching to new cell station.
I have just upload its radio to 0.16 via RUU, and hopes it would be more robust in switching

[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.

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.

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?
