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?

That thread has not been updated for a long time...
What would happen if I flashed that i9000 modem with a KB1 based Kernel?

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!
Im on Android revolution 4.0 ..2.3.2 and recently ive had this problem in my house (we normally dont have service in our house, we use an att microcell which provides 3g service around the house). My inspire will get out of range occasionally and it wont have any service, and it will stay that way until i restart my phone or switch airplane mode on and off. What can I do to solve this problem? will flashing my radio help?
bump............

I'm not sure if flashing the radio would help, it may, it may not.
Is it only your phone, or are others using the microcell effected? Are the other phones the same kind?
I'm not sure if I can give you any actual answers, just trying to help you in the right direction.
So my wife has the NS4G and it has had intermittent problems with network connections since the day she purchased it. Full signal on both wifi and 3g...unable to connect to network. I imagine you're familiar with this problem.
If she swaps for another NS4G will the issue alleviate itself? Is there a rom out there that fixes this...currently running oICS. Any help or advice in getting a different phone from Sprint? It has been 6 months with this phone. They actually offered her a HTC Hero today...that's what got me enraged enough to get involved.
Any and all help is greatly appreciated.
Try latest radio in 4g dev section (kL2). I've had excellent results with this radio.
I used the modem from this post
http://forum.xda-developers.com/showthread.php?t=2111799
And flashed it in the phone section of Odin without a problem. But I noticed that under baseband only half has changed to lp11 but the second half is still showing stock.
My 3g coverage is awesome but my 4g connection is still suffering and wondering if because of that
Any idea why?
It's this affecting my coverage?
Is there a way to fix it?
I appreciate the help.
I've got a Oneplus One - and ever since I can remember my signal drops (from full bars to no service) once every 10-15 minutes. I've tried factory resets, caulkin rom, slimsaber rom, stock kernel, ak kernel, and flashing different modems - the problem is still there!
Does anyone know what I can do? Should I ask OPO for a replacement? Really hoping for a fix - any help will be greatly appreciated!
bump..
Can you provide a logcat/kmsg?
I'm not sure what that is tbh. Sorry - guess I'm more of a noob when it comes to anything more than simple rooting and flashing. Point me the right way and I'll get that to you

Okay - I've got the logcat and everything installed. As I wait to reproduce the error I realized that it doesn't occur as I thought it did.
The signal drops a lot when I'm driving or if I'm in a poor signal area. I guess it goes to no service when its switching between towers or from lte to h+ to 3g. If I'm in a poor signal area it does the same - goes from some service to no service.
But then again, i do remember it going from 4 bars lte to zero service and then back to 4 bars lte. Just don't recall if this was while driving or not.
I'm going to get you a logcat soon - perhaps take my laptop and drive around to reproduce the error. In the mean time, does the above information help at all?
Thanks so much!
