hey guys,
for over two months now, my phones does not want to connect to the 3g, even in places where it used to (ie, my house). I have tried using the service menu, different apps, the network options, and have looked high and low but all the threads I've found end without an answer.
Right now i have,
2.2
Baseband: I896UXJL1
cognition 3.04
Any suggestions would be greatly appreciated.
What happens if you go back to stock?
Sent transparently through the tubes.
hmm good questions, last week when i went into 2.1 to update cognition it was on. After I installed cognition it was on for 3-4 days, but then over night it switched by it self and I have not been able to get it back
Have any other 3G att phones, its a long shot but once I had a similar issue, put my sim in another phone left it on for a few min then put it back in my captivate and everything worked fine
If your phone has the extended power menu (hold power for options) there is a data network mode option, make sure it is activated. You may have hit it by accident.

What modem are you using? Have you tried flashing a different one?
Have you tried other roms?
I would consider going back to stock (sucks I know) for a few days and if it continues to happen, take it into att and see about a new sim card or a replacement. If it doesn't happen again, try a different rom.
Try going into settings - wireless and network - mobile networks - Access point names - Click the menu button - Reset Defaults.
Had a co-worker running stock and his 3G would not come on anymore I had him do this and has been working ok ever since.

Good to know.
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!
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

Hello im running Gummy Charged 1.8 GBE and today my phone didnt connect to 4g.
I have no data, and i tried resetting the phone, deleted all data in recovery, still no 4g.
Is this a problem with my phone or the network or what?
Didnt drop it or anything, no clue what is going on.
Thx.
Just asking the obvious, but when you go into settings> wireless and networks make sure it is set to lte automatic, and wifi is off. Also check to make sure you didn't accidentally disable mobile data in the pull down.

do you get 3G? do calls and texts go through? if all the usual stuff fails, you may have a fried 4G sim... you should be able to get another one from VZ
I had no 4G earlier, but did a few minutes ago when I looked, so it appears to have been network for me. I personally always assume it's network, because I haven't seen a case yet where it isn't.
Here is whats happening! I go into an awful area with no cell service and when i return into an area with good service... It shows all my bars, 3G icon, but its all grayed out and will not return with color... Also i have no data connectivity at all. The only way to resolve this problem is a reboot. I have the Nexus s 4G KL1 radio... This has happened twice in 2 days. Can anybody tell me what this could be? I tried the KL2 radio and the same thing happened. So I went back to KL1. I am running Cyanogenmod 7.1 stable. Any help would be appreciated, I like this phone and dont want to have to go back to my slow Evo.
Happens on ICS ROMs. I switched back to GB because of that issue.
OHHH ok that makes sense since i was on an ics rom... That sux i love the ics roms to. Is this an issue they know about and are working on?
Yes I am sure the devs know about this issue. A lot of people already reported this issue on the ROM's threads. I think there was a fix in the CM9 repositories that was merged this week.
well thats good news since were i live its not good service and im in and out of service a lot. Thanks for chiming in and letting me know! I was wondering if i had a bad radio or some thing lol...
This happens to my I9020T as well (with stock ICS, Pixel ROM, and Brainmaster's Stock and MIUI ICS ROMs). So, it's definitely an ICS issue. My network connection won't reconnect after I ride the subway (underground, where there's no signal) for about an hour. The only way to fix it is by doing a reboot (enabling and disabling Airplane mode doesn't fix it).
I just tried switching radios: from KI1 to KF1. I'll update on the result later tonight.
Sounds like exactly what happened to me.
I went back to gingerbread. I haven't had the issue since!
Just out of curiosity have you tried the KL2 radio with CM9/Latest nightly and then toggle your Data Enabled or the data roaming? If that works it might save you the reboot. Settings, wireless & Networks/more, Mobile networks, Data enabled.
You could try toggling the data roaming too.
Yup tried it already

Ok it was worth a shot. When I travel to the UP, I get no data service what so ever. So I feel your pain.

I've tried enabling-disabling Data as well, and it doesn't fix it.
The weird thing is the same issue happened to my girlfriend's T-Mobile G2 with Gingerbread last week, when I unchecked the "Use only 2G network" setting on her phone and forgot to check it back. So, when she told me the issue when she got home, I re-enabled the "Use only 2G network" setting again, and her phone haven't had the reconnect issue ever since.
So, my speculation right now is this reconnect to network failure issue has something to do with the Nexus S' 3G/4G network type setting.
I definitely think you're right
I am having somewhat the same problem.
My phone keeps switching from UMTS:3 to HSDPA and back to UMTS:3
This is draining the hell out of my battery. But when I have it on EDGE 2G I'm getting good battery life.
the issue is not that big for me. I just give it a few moments with it in sleep and when I go to use it again it fixes its self.

Update!!!! I have since switch off of the I c s rom. I have not had the incident happen even 1 time since doing so. I am totally convinced it's on ice cream sandwich roms.

I doubt the radio would make a difference. I think the issue lies in the Phone application.
I could be misinformed here, but if i recall correctly, our phones radio is relatively stupid as far as radios go, and the intelligent parts are actually done as a part of the phone application. This only applies to CDMA Variants of the Nexus S, but it could be the reason that the ICS update was pulled (As thats where CM and others get the ICS version of the phone app.).
After taking the subway for about an hour last night, my NS actually reconnected when I got back up to ground level. One thing that I didn't do is listen to music (PowerAmp); I was always listening to music when I had those network reconnect issues.
Anyway, I hope this issue gets fixed in the upcoming official Google ICS update, that should be released in a few weeks*.

I've found that if you just stick it in airplane mode when you are about to go into known no service area and then take it out of ap mode when you know you have a signal you can save from having to reboot to reconnect.
My building at work is a tomb for sprints signal and it works for me every day w/o rebooting ...
To all of you having network reconnect issues -- do you use any battery saving apps, like JuideDefender or GreenPower? I use one, and I'm thinking that its network toggling internal API method has something to do with this issue.
Yesterday, I disabled my GreenPower app right before I took the subway, in which my NS couldn't receive any network signal for about an hour. Then, when I went back up to ground level my NS was able to reconnect to my network successfully.
I'll do the same test later after work and update back tonight.
