I seem to be having an issue with my data and am trying to narrow down the reasons for my problem. The issue is I CANNOT use HSUPA (H) for data, I always get a connection timed out issue. I put the phone in 2G GSM mode only and have data working, but of course I was spoiled with better speed I can't stand it.
My question is if AT&T could be doing upgrades to the towers in my area, will that affect my speeds, or is something broken internally in my phone. When I select WCDMA mode, it takes FOREVER for it to connect and says searching for a long time but does connect or displays (H) with 3/4 bars of signal. My friend has an unrooted captivate on 3G and has no issue with data. Does anyone know the cause of this.
I have tried a few different modems (jl3, jk4, kp1....) all the same and have tried 2 different OS's with same data timed out issues while trying to use (H). I am currently in the process of flashing back to stock to see if that will resolve the issue. Thank you for your time guys.

H doesn't necessary mean HSUPA. It simply means HSPA (HSDPA only or HSDPA and HSUPA). You didn't mention anything about your firmware but I guess you are experiment with non-Captivate firmware and modem combination trying to get HDUPA working. From what you described, it seems your current firmware and modem combinations lacks 850MHz support for 3G (most European firmwares lacks 850Mhz) and your local tower happens to use 850MHz, not 1900Mhz. Just a guess.
Make sure you have the modern set to proper frequency (WCDMA 850 or 1900) for your area. The modem thread can tell you all about how to do it.

Sorry guys, I guess that was an important part I forgot. I was running Andromeda and thought the same so tried Cognition 4.1.1. Also after going to stock 2.1 I still have the data issue. I can connect to wifi just fine, but no using ATT data will work.
I called customer service and walked through the steps as usual and after some looking into my area, he said there were 3 towers reporting severely degraded. It just sucks seeing my friends phones working with no issues. He said that repairs are stated to be finished sometime in the next few days and to call back later in the week if the problem persists.
Looks like you tried both i897ROM and non-i897 ROM, so it's not firmware related.
Did you try to put someone else's SIM into ur captivate? How about some other devices in ur area?

I didn't think about trying my friends sim card. I will test tomorrow morning. Ty for the idea to isolate the problem to my phone!
umm not really related to your phone. but im suggesting its the tower upgrades getting them ready for 4G that is causing your phone to act up. i have a HD2 and we have 3G down here. but since early march i get nothing but EDGE. what happens in the month march? AT&T will be launching 4G in selected markets. it was confirmed once i was talking to a AT&T tech. so im just waiting to see what happens in the end of this month.
NOTE: it could also be your sim card having problems. AT&T replaced mine thinking it was a problem with the sim card since i have a AT&T native W350 and i was getting the same problems. call them up again and ask to talk to a tech and tell them your having a problem with your sim card. they will set you up a appointment at a corporate store. free of charge.
I did not think that the Captivate's hardware was capable of HSUPA?
Is it?

you would have data, but no voice
Sorry for nor replying sooner. My 3G data seems to be working again. My lack of in depth knowledge is why I put the hsupa above when my phone displayed H I didn't know what to call it.
It must have been tower upgrades. I didn't restart my phone and left it on the charger overnight and the next morning I had no issues. I did a reboot of the phone as a test and connected with data with no issue. Too bad as I was close to getting a replacement, though it would suck and be my luck to get one with other issues. Mine is a 1007 and works perfect (other than the obvious GPS.)

That is what I thought, thanks!
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.

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.

If going back to GB doesnt help, maybe it is hardware related?

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

mine shows "unavailable" when it's wonky
and wont re-aquire till i reboot.

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?
Just wondering if any one else gets this, sometimes my signal just drops out and I get no service.
Then it comes back it does not happen all the time, I live in a big city Leeds infact so signal is quite strong.
Just wondering if it could be a fault with the phone?
Thanks
I've noticed it happens to me too.

I was wondering if its my device because I live in the city and the signal is excellent around here, my other phone HTC sensation never had this problem. Was concerned it could be software/hardware problem possibly.

It is definitely possible.
I'm on AT&T and have the correct APN settings and have called AT&T with my IMEI. I have significantly worse signal than with my HTC One X. I am not comparing bars to bars, but rather where the signal drops completely. In places where I had low signal but still connected I now have nothing.
Straight talk using at&t Sim and notice radio drops..

T-Mobile on stock ROM i had my first signal drops.
I was fine (or at least never noticed them) from the time i got my phone (day one) without any drops here in orlando.
Drove over to Tampa/Venice Beach area this past weekend and noticed some drops. Had about 6 drops according to my battery stats in 2 days. i had good to excellent coverage the entire time except when it would drop comlpetely (outline of signal bars)
would connect in a couple seconds, but i noticed over night, it would drop for a pretty large amount of time (like 10-15 minutes at a time.)
Mmm defo seems like were all having the same issues, wonder what it could be

I had this issue too, and here's how I fixed it:
By default LTE is enabled, meaning the phone will periodically scan for a LTE network. If you're in a big city, you're likely to find one. Your phone will attempt to connect. However, it fails, meaning it will have to rescan the HSPA bands to connect back. That results in a few seconds of no service. Why can't it connect to LTE? Because by default, the APN is not the LTE APN, for Rogers at least. I'd assume AT&T would be the same. You can test this by dialing *#*#4636#*#*, selecting phone info, and selecting LTE only. You'll see that there is no service. I tested this in an area I knew had great LTE coverage, and that led me to the conclusion that it's LTE causing the signal drops.
So how to fix? Simple, just change your APN to the LTE APN for your carried. To do that go to Settings -> More -> Mobile Networks -> Access Point Names. If you're experiencing this issue on Rogers, change the APN field to ltemobile.apn. If you're on another carrier, you'll have to search for their LTE APN configuration.
After doing this your phone should start connecting to LTE again, and you won't get those annoying signal drops.

So yeah the next update will probably fix the issue. It's not so bad in the meantime, Lightflow sill notify you that your nexus has lost signal, and you still get the internet and incoming calls.
We're not alone. Supposedly Google is "aware" of the issue.
i've hcanged my setting from '4g' to '3g' to see if i notice a difference (hopefully will) then when 4g is released or i get a 4g sim, can move it back up
Yes, I'm having issues too. The real problem is the fact that I have a Wilson cell booster in my home (supposed to have up to 5000 square foot range) and my n4 had full bars most everywhere inside. With my n5 It shows 1 to 2 bars if I'm lucky and quite often drops to none! The only way to get full bars Is to stand right under the indoor antenna. Not impressed, and I sure hope this is fixable!

I hate to revive a dead thread, but I was wondering if people were still having problems. Once or twice during the day that I can see I will lose signal for a few seconds only to have it reconnect. Running 4.4.2 so the latest update did nothing to help the problem as far as I can see and I have messed with my APN settings. On AT&T. The Google thread seems to have a lot of different problems on the same thread, and it is a bit unclear if people are still having this problem. This is very annoying for such an otherwise spectacular phone. Thanks and sorry again for reviving the thread... :fingers-crossed:

Actually, there have been several threads on the issues associated with this (emergency calls only, missed calls, no signal,etc.). Ongoing and unresolved for some.

Appreciate the speedy reply. Hope Google gets on this fast. I also have LTE connection issues which has plagued both this and my original device so I am pretty sure its a radio issue. The phone loves to stay on HSPA+ even when there is a decent LTE connection: it's last in the pack to connect to LTE and first to disconnect when compared to others on AT&T.

My N4 with a combo radio sticks to LTE a tad better than my N5 with stock radio. Sadly, morrislee hasn't fiddled and combo'd N5 radios, and I'm not sure they've been tested and sussed out like the N4 radios. Citing the fact some with issues have flashed all the radios so far with minimal success means we wait for Qualcomm, after Google kicks them in the you know where.

Hello everyone. I was hoping that some of you that are more knowledgeable about this stuff could help me out here. I recently flashed from CM 10.2 to KitKat (4.4.4), which everything went smoothly for the most part. However, I've noticed that my phone constantly has no service. I should probably state that I live in an area with very low service to begin with, but prior to the flash I was able to get at least a bar inside my house. Now, I'm unable to get anything.
The first thing I could think of to check was my settings in the phone. The data is enabled, CDMA Roaming mode is set to automatic, CDMA subscription is set to RUIM / SIM, and the Preferred Network Type was Global. I wasn't familiar with the global setting as I was used to seeing the LTE / CDMA / EvDo options there. So, when I clicked on it, it now gives LTE, 3g, 2g, 1x, and Global as options. I tried changing it to 3g, but the changes would not save that way. The only way I could get them to save was to power off the phone, take the sim card out and put it back in, and then reboot and switch them. Once i pick a new setting (which is now set on 3g), it locks it and I can't change it again without removing sim card.
When I look in About Phone > Status section, I'm seeing the network says searching for service. The mobile network type is unknown. The service state is out of service, and the mobile network state is disconnected.
Is there anything I can do to fix this issue? If so, I would truly appreciate any type of guidance you guys or gals could give me. Thanks!
I didn't read your entire post but myself and several others have reported signal issues after 4.4.4 flashes on all different ROM types. I think 4.4.4 is just picky about what firmware and baseband you're running. I flashed a few different RPM packages too but in the end I got lucky flashing the BLK3 modem and it seemed to fix my issues. I had noticeably poor signal strength most of the time and a couple times I would look down at my phone and I'd have no signal at all.
Maybe a dev or expert can shed some light on the root of the issue. I don't know enough about under the hood stuff to make an expert diagnosis.
Edit: The unanimous fix that everyone appears to agree on is to flash the MF1 AIO (all in one) package and then flash the ML1 modem only. Problem is finding a legit source for the MF1 aio package seems to be up in the air.
Like I said though, I didn't even do this. I was just trying all kinds of combinations of modems/aio's/ and rpm's and I got lucky. 2 days now with a solid signal at all times. LTE speeds are blazing too, 45 down and 10 up.
Check ur imei number. Or flash a backup and see if that fixes ur problem.

About 3 weeks ago after installing the update of liquidsmooth 4.4.4 i randomly started dropping to 3g service in places that i normally had full 4g available. It has slowly gotten worse to where if im not on wifi, than the phone is pretty much useless. i normally have full coverage everywhere. so i originally thought that maybe something had gotten messed up on the update, so i did a clean install of liquidsmooth 4.4, and blackbird kernal and same thing still occurred. also tried carbon rom and slimrom, and no luck. so for the fun of it, i went ahead and reflashed the phone back to stock from backups and rerooted it, updated the modems and reinstalled liquidsmooth w/ blackbird kernal, and same thing. i have went through all the mobile networks settings and tried everything and nothing seems to help, idk if that update screwed something up or if its an issue that others have been experiencing as well, or if im just screwed and my phone phone is dying.... any help is appreciated thanks

I'm currently running OmniToad, and ran CM 11M8 for a short while. On T-Mobile at least, with the custom ROMs it's normal to see H+ only when data is being transferred; it will drop back to 3G otherwise. When I ran the stock ROM on the Relay, it would always say "4G" regardless of whether it was in UMTS (3G) or HSPA+ mode. Apps like SignalCheck or CellMapper will tell you which mode it is really in.
On the other hand, if data transmission is only going through as 3G, it could be a phone issue or a tower issue. Is LTE available in your area, or are they just getting it set up? I know when T-Mobile was upgrading the Chicago area to provide LTE, there were a few glitches here and there.
It was stupid for T-Mobile to brand HSPA+ as "4G" but that's a different rant.

yea LTE has been in this area for quite a while now, i had it with my S4 and it worked perfectly, i never had a problem with the service on the relay either up untill a few weeks ago the internet speed and and data coverage was great, not quite as fast as the LTE on my S4 but it was still more than adequate, i used to use the hotspot and stream netflix on my laptop. now i can usually get a text to send but calls usually fail and if i try and use the internet its impossible. it almost seems like its doing the exact opposite of what it should be doing, as soon as i try and use anything (not while connected to wifi) than it drops coverage to 3g/edge/ or to nothing at all. Im leaning towards the hardware failing side, but i figured i might as well give it a shot and post it and see if maybe i wasnt alone. thank you for your reply.
small note of background on me: first time posting ever in this forum but have been using the tools and roms from it for a long time, so im not a complete noob, but i definitely still have a lot to learn.
