Personally, I had this issue the first time i flashed test4. No data without wifi, and voice bars were very laggy. I switched back to my stock rom for a day, and when i returned to play with it that night (reflash from .zip, not restore from backup), no more problems. The initial transition to 4g from 3g seems to take a bit longer than on the stock rom, but once it is up, everything is smooth. Not constructive, I know, but it is a data point.
ok thanks. but which is the link to test 4. i have a feeling i installed the wrong one. can u send me link if u can? thanks
Check the device thread on cm7 pre alpha links are at end. You want the one with a three which is actually the fourth one.
Here is how to get signal.
1. Goto network settings, scroll down to network type, select the cdma/edvo option.
2. Wait until green 3g. If it doesn't pop up repeate step 1
3. Once green, change setting to cdma+lte/auto and hit your screen off button. Don't touch phone for 5 minutes.
I'm not sure turning screen of makes a difference but this is how I've repeatedly done it.
I have found that if you loose 4g you can loose all data. Just repeate above. It seems to work for about 10 hours then a reboot is required.

tonyagee is correct. This worked for me when I originally had your issue.
thanks guys but this doesnt work for me. ive tried it with stock and leaked radio.
I too have CM7 and have issues with data/3g. I'm not in a 4g area so I can't speak for LTE. What I noticed is that if I'm connected to a wifi-network and move out of range. My phone has a hard time getting into 3g and vice versa. If I go from 3g to wifi. Same thing. It appears that this is a bug but I'd like to find the buglist so I can confirm. I have, however, been able to get around this issue by rebooting. A good indicator of data transfer is when the wifi icon or 3g icon is green and in the case of a 3g icon, the arrows are flashing. If they are white, you are connected, but you aren't getting any data.
Not sure if this answers your question but I would try the wififix that Imoseyon made (link is in the CM thread somewhere). I enabled 3g, then rebooted into recovery and flashed the wififix file. Once the phone rebooted, I was able to move between 3g and wifi without issue as long as 3g was enabled first.

I've been trying to search about this but i can't seem to get the answer.
I heard about making new APN's but it doesn't work for me.
All it says is "access to this url is blocked" or something like that, i can't seem to use it unless i use Opera mini.
Btw i had this phone for like a month already.
thanks in advance.
More info? What kernel, android version, ROM?
2.2.2, no custom rom, 2.6.32.9-00007 is there more to the kernal?
I have the same issue once in a while. It's almost like the data is stuck on something. A reboot usually works for me. I'm on mobile so I can't see but are you with bell? Asking as I am.

Good to know I'm not the only one.
I allways blamed my carrier.
I use Signal Refresh, its on the Market. It helps sometimes. I allways end rebooting the phone.
I'm on 4.5.9.1 right now, but I've experienced this issue since 4.1.2.6.
weird i restart the phone and i still can't use the stock browser always gotta go to Opera Mini. Opera Mobile doesn't work for me either this is weird. I am on att btw should i bring it back to a att store?.

Even though your homepage is blocked on your stock browser, can you still navigate to a different website?
Like can you navigate to Google.com, or is that blocked too?...

Today I had this same issue.
No data. I tried refreshing the signal, toggling airplane mode, rebooting...phone would send or download data sometimes, but it never loads a web.
I ended using wifi to write this answer.
I hope this issue get fixed somehow.
Had same issue myself for the first time today. Never had this before. I'm on 4.5.91 beta 3, and I didn't realise at first when I lost all data that my signal bars were telling me something. On stock GB the signal bars are blue when you have data, but they turn white when you do not. I saw 3 white bars and thought I still had signal when in fact I did not. Tried rebooting, got blue bars for a couple of seconds, then white again and no data. I actually had to go outside my work, at which point I picked up a strong signal again, and I have been fine at work since. Very wierd, but it's almost like the radio lost the signal, then could not acquire it again without me being outside where it possibly had line of sight to a tower.
weird you guys only get it sometimes?
Mine has been like this since day one and it's already been a month and a half.
APN Settings.
There's a thread I posted a while back with all the APN settings for AT&T. Try to add these and see if you can't get it working.

By chance did you just start having these problems after installing the leaked version of the updated Market? Whenever I run the market, downloads are very flaky, I get a few force closes, and my connection seems to just drop out entirely, from apps, browsers, etc...
It picks back up eventually if I close the market app whichs eems odd
Just got to work this morning, went to new Market, (leaked version), and as soon as the app came up my 4 blue bars turned white..............no data again! Something with the new Market is definitely messing up data connectivity.
<edit> Rebooted phone, tested data...............working fine on everything. Start Market again, blue bars turn white, no data!
yeah, i went to manage apps and selected uninstall update to market. Rolls it back to the original.
nope checked the APN's still the same should i go back to att with this?
Alright, I rooted my phone and installed CM7 about 3 months ago, and had no problems ever until recently. My phone started force closing the messaging system and my media system. Then, I restarted my phone and it got stuck on the Vibrant screen, before the skateboarding CM7 android. I ended up flashing my phone back to the Samsung Vibrant T-959 stock using ODIN, but since I have Cincinnati Bell, I had to use T-Mobile's stock. My phone works perfectly fine except one thing... I DON'T HAVE DATA! I can't get online or access the market... It says I have no internet connection. Can anyone help me?
If there is something out there that I can use thats better than this T-Mobile stock software, please let me know... I'm open to anything at this point. I just want something stable and clean.
This sounds like the problem I have everytime I flash a Froyo ROM of any sort: I lose my APN.
You can check to see if that happened to you by going to Wireless, Mobile Networks, and checking to see if any APN is needed. If it says something along the lines of "Enter New APN?" or some such (I'm on MIUI at the moment so can't be exact), then your APN got wiped. Cincinnati Bell lists the correct APNs for the Vibrant on their website.
http://cbwportal.wdsglobal.com/phon...31&mobileNumber=&contractId=185&step=phone.vm
Go there, and enter both the WAP and MMS APNs, selecting the WAP one. Also, to curb another common problem, don't enter a Proxy for the WAP. It causes major browser slowdown and you data works just fine if not better without it.
did u try....
Taking the sim card out? Had the same problem, I took the sim out and put back... problem solved.try that
Hey, I'm having the same problem. Mine shows that I am connected and have full bars with 3G or H access. However, when I try to use the browser, gmail, market or any other app requiring data, it says that it fails to connect. I've been struggling with this for a couple of days now. I've already tried removing the sim card and resetting everything. Any help would be awesome, thanks!
Hey guys i got a problem.
After flashing my phone normally with Odin like usual all of a sudden data connection aint working anymore. I works fine with wifi, but not without.
It shows 3G/H signal in the status bar, and i see the upload arrow is blinking so it is sending data, but not receiving anything.
I tried googling it, tried flashing various different roms that worked before and original firmware, but nothing helps so far.
I checked the provider info in the phone, and its all correct.
Kinda lost here, hope someone has an idea how to fix it
thx in advance
nobody? i tried everything so far and dont even know why its not working anymore
It's going to be difficult to get much help here because I don.t think most developers have had time yet to get into the innards of the A501. Have you tried flashing back to the original stock ROM? You did back it up before you flashed it with a custom one right?

No nandroid backup, only titanium backup since i never had problems before.
I tried flashing all kind of original firmware now, KH1-3, even older ones, the latest. tried all custom roms that worked fine before.
Tried different sim cards, readded the APN settings etc.
Found out now that 2G is working, but as soon as i switch to 3G etc it shows the signal for that, i see upload but no download, so it basicly stops working.

(Instead of quick reply, i hit thanks first!)
Dial *#301279#. If it doesn't work, dial *#*#301279#*#*
Select 2nd option (Change HSPA revision or whatever).
Then select 3rd option (Release 6).
Restart.
Also, check your APN settings.
Use an app called Tweakker which will configure your apn if u dont know exact settings.
thanks for the quick replies guys.
so i did play with the codes today already, the option you stated i tried but sadly it didnt change anything.
HOWEVER i did choose disable HDSPA completly now, so i am on 3G only and guess what, now it works!!
Speeds are not what they used to be at this location, but that might be due to my data limit so i have to check.
With other codes i found out that while being on H/H+ phone didnt download 1 byte, so i have to wonder why.
With 3G it is working now, but what could the cause be. Used to flash quite often and it always worked, so not sure if thats even related to my problem atm.
Any idea what might cause the H stuff not working at all? I read about the SII getting stuck on H+ etc. before, but all the tricks with rebooting or toggling flight mode etc. didnt work for me
so far, thanks a lot!
Try different modems. Depending on ur location and service provider, atleast one should work right. I'm using KI3 modem without problems.

modem depending on location and provider?
i tried several modems from the original firmware thread under development. they all used to work fine before, now they dont. KI3, KI8, KH3 etc. all nothing :/
Hmm strange. May be you should delete all apns, and configure a new one for your provider.
Also give KG5 and KG2 a try.
i am having a SGS2 with KI3 and sensation rom 1.7 with kernel siyah 2.0. after doing this i am also facing a problem with my data connection. it works but its on / off.
can you suggest come remedies like now please .............
I am new to root and ROMs so perhaps I overlooked a setting.
I just rooted my phone and flashed CM 10.2 a few days ago and I cannot get 4G anymore. I can only get 3G. I have tried a few fixes like dialing *#*#4636#*#* and adjusting the APN settings but nothing worked. I have the LTE button ON and I am wondering if I am still getting 4G because I have LTE on and it's just showing 3G. But I don't think that's the case.
Any help or tips would be greatly appreciated!

reflash stock rom. make sure you have 4g. flash the vram3c radio then flash cm10.2 rom. you should have no problems with 4g after that.
I will try that. Thanks!

I tried flashing the radio and CM again and sometimes 4G comes up for a few minutes and goes back to 1X. This happens where I have gotten 4G before. Maybe the radio isn't as strong?

My personal experience, living in a fringe signal area, is that AOSP roms just don't have as strong a signal as TW roms (it presumably has to do with how the RIL had to be hacked/reverse-engineered to work for AOSP). I would prefer running AOSP, but unfortunately in my experience on my S3 and Note2, where I am located on the fringe of full 4G coverage areas, I have the same issues as you: on TW, full, fast, 4G; on AOSP, very obviously slow 3G or 1X.
Edit to say I've only tried 4.2.2 ROMs, haven't tried the 4.3 ones yet, so if I'm handing out wrong/outdated info, I'd love to be corrected.
I am now running a stock 4.1.2 ROM and still cannot get 4G. I now for some reason can't even dial *#*#4636#*#*. When I try it just says "Welcome to Verizon Wireless, this call cannot be completed as dialed." Anyway to get that number to work so I can check my networks again?

Try going into settings and factory reset phone now. If that doesnt work, reboot into stock recovery and factory reset from there and reboot. That seems to restore signal for those of us that got stuck in roaming mode from the Carbon thread. Might help your problem too
So I decided to re-flash CyanogenMod 10.1, adjusted the APN settings again, and I have 2 bars of 4G right now. Usually 4G will flash a couple times and change to 3G, but it is staying 4G, so hopefully it stays that way!
Well it stayed 4G for a bit until I turned WiFi on. The moment I turned it on, my 4G went to 3G. I turned WiFi off and I still have 3G. Anyone know what would cause this?
EDIT: My network type shows eHRPD with 3G, where as when I had 4G (before I turned my WiFi on) it showed LTE. If this helps any.

Where do you live, i know the mid Circle drive all the way over across platted to the airport are just dead zones. I lived on Verde drive and rarely had good signal, then when i moved up circle behind the bowling alley i never had a good signal. Just something about the antennae in that area. T-mo is a complete bust in that area. But i'm sure you probably all the way over on the Nevada side completely making what i said irrelevant.

Do a search on towers in your areas. If I remember correctly the closest tower to you in right by the interstate by the new (now not so new) MCD's in Security. That tower had alot of problems in the area past the Olympics complex all the way back to Peterson because of the radio towers for the Jets. I have been gone for almost 3 yrs so don't take what i say as truth tho. Just how it was when i was there.

I've had that problem before. .I used a mod like this.
This mod is from DroidXcon, Try this and hopefully it will work. (make a backup of your buld.prop first)
Instructions:
1)Go to market install BuildProp Editor
2)Once installed find and open Build Prop Editor
3)Hit the menu button and select Edit
4)Scroll to the bottom of screen and add the following lines
Code:
ril.sales_code=LOL
ro.csc.sales_code=LOL
5)Hit the save button at the top right hand corner of the screen(looks like a disk)
6)Once this is done saving restart the phone
7)After restarting go to Settings>More Settings>Mobile Networks>Access Point Names>Menu Button>+ New APN
8)Add desired carriers APN info, when finished hit menu button and save
9)Power down and change to your desired SIM card if you hadn't already done so
10)Power back on and go to Settings>More Settings>Mobile Networks> Access Point Names (if done properly you should see the APN data you entered for your respective carrier).
11)Select the respective APN listing and then you should have working data

I tried this but having the same problem, so I decided to save the APN each time I edited an item, and every time I would change the MNC and save, it would not be on my APN list, and it would be blank again.
Bump... also having this issue. Trying CM 10.2 for the first time since August. It had Bluetooth issues back then, so I've been running Bean's ROM until yesterday. Can't get 4G serivce in what is absolutely a saturated 4G area...
Was able to fix the issue by wiping the phone completely (including internal storage!), installing Bean's ROM, doing a factory reset, then coming back.
FWIW I always wipe internal storage when going back and forth between 4.1 and 4.2+ roms, seems to alleviate any SD card issues that can arise from the changes to filesystem in 4.2.
