AT&T data connection problems on Kaiser

Hi -- I've got an unlocked Kaiser 100 which works fine in other countries (SFR network in France, O2 in Ireland, etc...) and _has_ worked fine on AT&T in America until recently. Suddenly, the data connection has started randomly but chronically started going dead on me. The problem has nothing to do with connection strength: I'm in Manhattan, which generally has excellent coverage, and the connection can be at four bars on HSDPA, and I still won't be able to download _any_ data. Sometimes the four bars HSDPA icon will suddenly change to the no-connection icon for a moment and then return to four bars HSDPA again. And this happens completely unpredictably: the connection is sometimes fine for hours and hours, while at other times I won't be able to download any data for minutes at a time.
I've tried many different connection settings, some with proxy and some without, and haven't been able to fix the issue. AT&T support has been, of course, completely useless, and just stay that these problems happen with unlocked, non-AT&T branded phones.
Does anyone have any ideas? I'm using the stock ROM that came with the phone (and which worked great with AT&T until recently) and I've tried doing two soft-resets, neither of which have fixed the issue.
Thanks!
Alan
p.s. Does anyone understand why a "search this forum" search for ATT or AT&T turns up _nothing_? There are many posts that mention AT&T, obviously, but I can't find any of them doing a search. I wonder if someone has posted on this issue before, but I have no way to find out.

You didn't disable anything with an adv config tool by chance?
You are sure you covered "disable proxy"?
Settings:
Name: MediaNet
Proxy settings: None and "This network connects to the internet" marked
Access point: wap.cingular
Username/password/domain: LEAVE BLANK (don't ask why just leave BLANK)
Adv settings: User server assigned IP address
IP header compression
Servers: All empty
I had a similar issue a few weeks ago and AFTER removing username and pw all worked out well.

Thanks for the response -- yes, those are exactly what my settings have been too. They seem to be working fine right now, but I'm sure I'll have connection issues again later today or tomorrow.
Thanks!
Alan

Thank you for that. Telling me to delete my UN & password in media net settings. For some reason, that has saved me from wanting to destroy my mother ****ing phone.
With the UN and Password in there, my phone (when in use as modem for laptop) would ONLY allow me to run google searches, and visit the paypal website. Note, I couldn't actually click on any google result, as it would then resort to error 404
Thank you again, for lending me the tip that makes my phone work like it ****ing should have out of the goddamn box

I'm having data trouble as well. Everything worked fine as of last night. However, this morning I found that I could only connect to the Internet with Internet Explorer. Other browsers, Opera Mini, Opera 8.65, all hang. SiriusWM5, SelectRadio, Resco Radio, youtubeplay and other Web-enabled programs can no longer connect. However, QuickGPS still works as does RSS Hub.
I've tried to tinker with the connection settings, including using the advice in this thread Nothing works. I ran connection setup to just restore the original settings. Nothing. I can only connect with IE...I'm posting this message with it. Any ideas on what the problem might be that would allow some apps to work and not others?
UPDATE: Opera 9 and Netfront 3.3 actually do work. Live Search works also.

Is Pocket Outlook working? I just called AT&T because mine stopped working today.

It looks like this is a widespread problem. Mine is doing the same thing. At least we know it is the service and not the phone.
Hust saw this post on another website..
"Just got off the phone with an AT&T Rep. The hurricane knocked something out and the data access is supposedly down in half the U.S. ETA was this afternoon per the rep"

good to know. but why would some programs work and others not? don't they all use the same port/server/whatever to access the Web?
this is still weird. but let's hope it's fixed ASAP.

seems they've fixed the problem.

Cannot explain how a network works in three words but services to support whatever network (DNS, routers, proxy's, NAT servers) are spread all over the US so if a major hub or datacenter has a problem, things go south, at least partially.

Yeah, looks like things are working now.

I've run into a similar issue except that my phone works OK in the US but not in Germany.
I have an AT&T Tilt with the latest official AT&T Windows 6.1 ROM. It works great here in the US. However, when I am in Germany, the data connection seems to drop and the only way I found to get it back is to do a soft reset. It then comes back for a while, but drops again after some time (maybe tens of minutes - there's an X next to the data connection symbol). After the soft reset I am able to connect to download say the weather in the built-in HTC Home. However, after several minutes the connection drops again and checking the weather results in the phone trying to establish a data connection followed by a message that the answering modem has dropped the call.
Anyone know what the problem might be? The issue seems aggravated while connected to Vodafone, less so when connected to O2. After returning to the US everything works as expected again. I haven't done any tweaks to change the data connections of the phone. KaiserTweak sees everything related to GPRS and data set to default. Some people have suggested getting a new radio ROM, but I'm not sure which one would work well in the US, Europe, Japan and Korea.

I have a CAB in the office for intl. data setup. Helped me in Europe all the time, will post tomorrow.

I will try selecting the carrier when I am in Europe next week. However, I'd prefer something that just works in case a particular carrier is not available. I am hoping the radio will work OK in Korea and Japan too.
tyguy: Do you know what the cab changes? Does it change the radio ROM code or does it modify some other settings? I'm curious as to what is causing the problem. Also, is this a one time operation or do you have to keep changing settings when you go between continents?

Would you have it available now? I'm interested in trying it out. Do you have any details on what it actually does?

@emuyshondt
You're not forgotten. I do not know what it does but it worked for me in Europe.
I deleted it from my email since a buddy of mine sent it while I was in Europe and didn't store it.
Let me poke around - I'll come back to you.

Here it is.

Thanks! I'll try it out this coming weekend.

Lemme know.

No Data after flashing roms, this is probably a stupid question...

Okay so over the past few days I've been flashing a bunch of diff roms to see what I like. I've had a constant problem with getting mms to work on any of them. Well I was doing all of this from home and always had wireless to use for data, hence I used it.
Tonight, however, after flashing a few diff roms I found out I didn't have a data connection at all. Tried a couple diff cm6 nightlies and the blackmod of cm6, and after flashing the only way I can access the internet is through wi fi. Otherwise I got nothing.
Sooo, maybe my mms problem was just this all along or maybe not. Anyway, what could be the cause of losing all data connectivity. Phone says it's connected in status. And the widgets somehow magically update. But the browser, market,mms, etc don't work at all.
I'm gonna flash the 0.7 aospmod and see what happens. Any help you can offer is appreciated.
And yes, I might just be an idiot. Forgive me.

Just flashed aospmod v.07 and same ****. No data connectivity.
What gives? I feel stupid.

a guess
possible APN settings issue, did you flash back to a 2.1 sense rom, and try an Over The Air activation and update profile?
I honestly don't know but thats a guess... I use my phone with pageplus (verizon) and editing my APN settings is what fixed it for me.

Ruu. Started fresh.
Everything seems to be okay.
Thanks.

This happens on a lot of roms. I've found to fix it all u have to do is toggle on and off either or both airplane mode and moblie network.

I found having to open browser and put in my cell number b4 sprint data would work, also prl update works for me.

I had this happen to me (including all bars showing and things refreshing) and spent several hours working on it only to determine the only solution was to RUU and start over....but its faster this time around because you have nandroids....just flash one after you re root from before you lost data (if you have one) and if not, back up your apps and data with titanium backup or mybackup pro...
(I had tried all the things listed in the previous posts....not saying they wont work for you, but in my case, they didn't)

[Q] No 3G on Rooted Samsung Captivate

I rooted my Captivate last night using Super One Click and the Youtube video from MobileTechVideos. I installed Titanium Backup and uninstalled all the bloatware along with Tethering Manager to allow for mobile hotspots. However, this morning I discovered I now have no 3G access and can only access the internet via my wireless network. I haven't come across anything online to suggest how to fix this problem. I've tried restarting my phone but this didn't work. Does anyone know how to solve this problem?

Any suggestions guys?

Use ODIN one click to go back to an out of the box state and see if the problem persists. If it does then it could be your hardware or AT&T's fault.

Sometimes the simplest things are overlooked. All I needed was to check Use Packet Data in the Mobile Network Settings. Thank you for the easy fix! I was getting ready to unroot and start again.

I am confused...by wireless network you mean like the one from your network(for eg: ATT) one right? your problem is that you are getting EGDE but not 3G? I am sorry I didnt get your problem.

Glad you did. anyway we are not perfect sometimes we may overlooked something due to excitement or what other feelings as a result of what we do and clouded up our troubleshooting instinct. The best way is to be calm and don't panic it's just part of being a rom flashaholic, overtime it will increase your confidence and skill.

Help! No Data and wifi Error

Hello all.
Ive searched (and unless I have no idea what i'm searching for) i can't seem to find an answer. I tried forum searches, browing through hundred of pages, and maybe its just me. Brain might be exhausted but here it goes. If it has already been solved then thank you in advance.
I HAD the VZW tab currently running the 2.5 alpha CDMA. After playing with it for a while I decided to go back to stock firmware because I wanted my 3g. The weird part was after factory reset and everything my baseband is now unknown and it can't pick up a signal. When i click on wifi I just get an error message. I tried a complete going back to originial stock with no root as per (i forgot to attach the link to the thread) but i still do not have service.
Under mobile networks (where there should be an option for GSM/CDMA/AUTO, that option is not there.
The activate with Verizon option isn't available that is supposed to be above wireless and networks.
Ive done factory resets, wipes, uninstalling voodoo, tried to updated modem.bin but it keeps failling.
Any suggestions?

Okay i managed to figure out wifi. I guess my mac address changed and i was using mac filtering on my router. Didnt know that address changes. Anyways anyone know how to get data back? I feel its in my modem.bin file but it keeps failing when i uploaded one that i found from a VZW tab

same issue I have
Wow I have same issue as your. Expect it is Sprint Tab. My tab couldnt pick up a signal and i tried to reuploading Modem.bin but it fail too. Let hope we have a solution

wow would not expect the mac address to change after a flash, I know that you can make it appear different >:¬}h
Had the same issue with phone, and had to manually input the ap settings from the carrier, but that was it, sorry for stating the obvious but did you try this?

The iemi and the mac adress can be changed by flashing. The data is in the system/efs folder.

Oh i know that but thought it was by design and not the event... New to me if it was.. I use additional security in wifi at him and by mac address and did not have to change... Interesting if this is the case

I experienced the same with my SGS (GSM), though I also changed the CSC. All that was required to solve it was to manually reenter the APs.

I was shocked too. I thought the address was hard-written into the chip too. I had to change the address in my router too.

I guess I felt that way too because i really only filtered computers at the house and no matter how many times i formatted I always had the same MAC address. Glad that I figured that one out so I at least can use my SGT in wifi mode. Now the issue is trying to get my data back on (Verizon) since I'm paying for it. *sigh*

I did but no one had any information to give. I was transferred 3 times. Oh well. Since I am practically running a wifi tab Ill just re update to HC Alpha 2.5 just because I like the interface better. Hopefully if someone can find a fix ill take it.

[Q] 3g no longer working?

Hello everyone. As you may guess from the topic title, I'm having a rather serious issue - my Captivate is no longer connecting to 3G or even to Edge - though it connects to Wi-Fi just fine.
It all started about a week ago, but has since progressed to a frustrating degree.
Basically, I was running Cognition 3.03, and everything was going fine - and then after hitting Flight Mode, I couldn't reactivate my data connections. I'd reboot the phone, and I'd be able to connect for about a minute or so after booting, and then Flight Mode would re-enable by itself; needless to say, it was very frustrating.
After looking around the Internet for some help, I eventually flashed what I presume is supposedly a stock rom - specifically I897UCKB1 - and thus we get to my current issue - no 3G access at all, no Edge, though I can still make and receive calls and send and receive text messages.
I guess it should be mentioned that I've had the phone about a year and a half (got it in November 2010, and therefore not up for a new phone until then), and generally put it to heavy use data-wise.
I had read somewhere that it might be an issue with my SIM card, but switching SIM cards with my dad did not solve the problem at all.
Could it be a problem with the modem or whatever that connects with the 3G network?
Thanks for your help (and for reading all of that!)

It does sound like you're having a modem issue. The easiest way to correct this would be to go to the Modems thread at the top of the Development section and find a modem that works with your ROM (KB1). Flash that from recovery and see if it fixes it.
If not, you may need to flash back to stock and re-flash Cognition.

Also, check your apn settings. There's an option to reset to default. Try that.

Sorry it took so long to reply - my home Internet access is... not good, so I have to go into the public library to do anything for the time being.
Anyway, my phone was being unruly and wouldn't let me do anything last night after I downloaded the modem that's supposed to work with my ROM - I couldn't even root it for whatever reason. I'm in the middle of downloading the supposedly official stock Gingerbread ROM (KK4) and I'm going to try from there later tonight.

Unfortunately I don't see anything about that. I go Settings > Wireless and network > Mobile Network, see Access Point Names, and it says it's empty and asks if I want to add an APN. I have no idea about what to do with that, so I'm not going to try right now.

once you Get to the screen asking if you want to add an apn, hit menu. One of the options should be reset to default. If you have no apn, that would explain why you have no 3g, etc.

Thanks for the quick reply.
When I go into Settings > Wireless and network > Mobile networks, it brings up a list of four items
-Use packet data (with the checkmark)
-Data roaming (with a checkmark, unchecked)
-Access Point Names
-Network Operators.
Clicking Access Point Names brings up a notification box APN Empty: Add an APN? Ok/Cancel. Hit OK, and it brings up a list of things for me to type in - hit menu and it only brings up Save and Discard. Hit Cancel, and it takes me back to the previously listed four items.
Clicking Network Operators shows Default Setup, but it's grayed out, and pressing the menu button does nothing.

Sorry for double post, but good news!
I flashed the 2.3.5 ROM I mentioned above, and it all works now!
