No Network Connection - Epic 4G Q&A, Help & Troubleshooting

Happened about a day ago...Everything that access the internet gives me an error connection when I have full bar signal over 3g on my epic. Wifi works fine and when it is turned off I cannot connect at all.
Running ECO5 lastest syndicate rom with genocide kernel if that helps. Hoping this is just some type of sprint network thing and not my phone acting up. I will try changing roms or reinstalling after a day or so. Anyone having this problem or know how I can fix it?
NEVERMIND IM A BIG DOPE data network mode was off..........DOH
Hope this helps someone.

Need Help, Friend Updated with Froyo OTA and Now No 3G Data?!?!?!

A good friend of mine waited to receive the OTA update of Froyo for his Incredible and when he got it he installed it. The bad part that I need help with is that when his phone rebooted it wouldn't allow the 3G data network to work. That section in settings is greyed out saying "Turning on..." and will not connect. The phone portion runs just fine. I have since returned the phone back to 2.1 and the same problem persists. If someone could help us out that would be awesome!!!
This probably wasn't posted in the right section...
I had an issue with 3G not connecting after downloading the froyo OTA off the internet and applying it as an update.zip.
I'm not sure if this is the same thing, but mine seemed to be that it wouldn't switch from the wifi network to the 3G network after getting out of range of the wifi (its set to auto connect to my home wifi, so it went straight to that after I rebooted it after the update). Then it wouldn't connect with the wifi off. I think I turned off both wifi and 3G and rebooted it with them off, and then turned back on 3G, and it worked. Everything is working normally now.
I'm not really sure why this would happen, I was wondering if it possibly had something to do with the phone registering itself after the update, and then not registering the 3G because it was on wifi and sort of "forgot?" That's just idle speculation though...
Also you might want to clear out your cache.
This might not be related to your problem, but I hope it helps!

Thanks for your effort, it did not work unfortunately.
Did he happen to have anything that controls 3G installed? Tasker? Juicedefender?
If he powered off while the data we disabled, and updated, then 3G won't work. Period.
I've heard of ways of restoring the APN or something, search the forums on that.

He did not have any type of app like that. He is a very novice user. I tried searching for restoring APN with no luck, anyone else?
When I first flashed Virtuous2.0 and did the initial setup, I didn't get 3G either. I'm pretty sure a good old fashioned *228 did the trick. I did have a backup through APN Backup & Restore, but didn't need to use it.
Have you tried turning on the airport mode, rebooting, turning off airport mode. Or perhaps do a *228?

Tried this too and no luck.
Go to Verizon and tell them to fix it fix fix it fix it! If he's running stock its nothing he did. Sounds super bunk that they finally got froyo only to not be able to use 3g.
The loss of 3g data is a bug with the froyo builds. All the froyo roms and the official ota have this issue.
sent from my Droid Incredible using XDA app.
this just happened to my friend too. I updated his phone last week with the OTA and since then he hasn't had 3g, but wifi would work.
did a rom manager backup before hand though, so i told him to revert back, and everything is working again. not sure why flashing back didn't work for you
So he hasn't had 3g at all? He can make calls and a *228 option # 1 doesn't update his settings and reboot? Maybe something when wrong on the install, whats hboot say?
Assuming he's completely stock I'd suggest going to the Verizon store and having them try.

[Q] Defy CM7 Data connectivity problem

Hello guys!
I have i little problem with my CM7: every time when i try to connect to internet via data networks it gets me the data connection error and it won't load.
I've searched for the right apn settings, i've tried to see if it was a problem with the browser, but nothing changed.
What to do? Thanks
Does somebody have the same problem?
did you try band switcher yet?

Defy as modem with Eclair?
Hi,
Can Defy with Android 2.1 act as model for dial-up connection to connect to PC? if yes then how?
Thanks in advance...
I also have problems with data connectivity as well. I don't have a data plan, but I use WiFi for all my internet needs. But in CM7 I could not for the life of me download a picture message. Download of message failed. I had to reflash back to xd1 to get it to download.
There is a problem with the data connectivity. Has anyone researched into this?
Yes, i've tryied the baseband switcher but with no luck
Any solutions?
Is anyone able to get data but having problems with over all speed? 3g acting like 2g? After I flashed cm7 i was stuck on edge. Found out about the baseband switcher and i have 3g back using USA baseband .9 but not the speed that goes with it. Right now I'm over my 200mb "4g" cap so i have to wait till the 5th for my cycle to start over. I got 3g back with 5mb left to my cap. So how is data working for you?
Flashed using
JRDNEM_U3_3.4.3-11_BLUR_SIGN
CM7.1.0-rc1
baseband us tmobile 3.4.2-107-9

[Q] 4G connected, no ip address?

So I recently flashed to gb rom starskyrom.. everything seems to be working fine but lately, 4g connects and doesnt find ip address. Ill have an idle 4g icon ( sleeping zzz...) but when I go to wireless settings>4g settings> and check the sprint 4g network it says ip address 0.0.0.0... but I'm connected? Because it thinks I'm connected, it won't fall back to 3g.. anyone else experiencing this? Does it have todo with signal strength? Maybe my rom?... but it was workin before... my modem? Any thoughts
Sent from my SPH-D700 using XDA App
Just got back from work, the 4g is broken on starsky 4.0, not sure how I thought it was working, but its not.
Not sure what would cause it, I'm also using starsky and have no problems with 4G.
Try the basic fixes
Reboot
clear and re flash
etc
If that don't work, it may be a problem with the network in your area.
Like the day I started trying ei22 roms and utah had its 3g die. I could not figure out what I was doing wrong.
So you have the same symptoms as described above?

[Q] portable wifi hotspot disables 3G ?

had the phone over a year now, never had an issue before.
As soon as you turn on the portable wifi hotspot, i loose the 3g/h symbol from the top of the screen and from that no data conectivity?
and as sopon as you turn the wifi hotspot off, it regains an internet conection
Any ideas, ive not installed any apps recently, as far as i can remember?
Do you get an internet connection when another device connects to your phone's wifi hotspot.
If you are able to connect, then it must be working, as it's the 3G signal that the phone uses to connect the wifi to the internet. It might remove the icon, but if you can connect then it's fine.
nope, can conect my ipad to the DHDs hotspot but no internet.
the same for when i turn the hotspot on, cant brouse anything on the phone as no data conection
still not sorted this, anyone else got a aide or something to sort this?
First post (longtime lurker)
I've got the same problem here although this has only started happening in the last couple of days. The phone's data connection is fine until you enable the wifi hotspot at which point the connection is dropped to the phone, connecting any devices to the phone is fine, they get an IP address and can ping the phone directly, but beyond the phone there's nothing.
Rebooting the phone does not help.
The only app I've installed recently is Google Shopper.
Out of curiosity Fil what ROM are you using? I'm on RCMix3d Runny 3.0 which is based on Android 2.3.5 and Sense 3.5. I'm looking at switching to an ICS build pretty soon.
It also looks like we're on the same network although I think that's just coincidence.
yep sounds exactly the same issue,
as for rom, still on t-mobiles original 2.50.110.5 Adroid 2.3.3
was thinking of flashing something custom to see if it solved the problem
I've just flashed IceColdSandwich today at work (it's been a slow day!) and you'll be pleased to know that wireless tethering is working again. I'm on the train home as I type this. It's possibly something in the 2.3 image? I can't really say since we both had different ROMs (mine was a Sensation port). It could just be a bad bit of code in the gingerbread OS that produces this bug on rare occasions.
It may have something to do with the fact that T-Mobile and Orange allow you to roam on eachother's networks. Do you have roaming enabled?
To be honest I'm just stabbing wildly at possible causes here and a flash fixed it anyway. I went ICS but I don't think you'd have to go that extreme but flashing a new ROM overwrites whatever it is that caused this in the first place.
I'm just hoping it's fixed in ICS and won't happen again!
cheers, enabled data roaming, and it now works!
Since the issue, my batterys turned to crap! guessing thats the cause constantly jumping networks, and also data speeds have been very poor lately, was ok when just t-mobile, but orange is poor!
Off to the t-mobile foeums to see if its just me, or others!

Internet not working.

For the past week and a half, I've had internet issues when I'm on 3g. It works fine on wifi. I've switched between ROMs, kernels, modems, etc. I'm currently on Goodness with the MA6 firmware modem AIO and the anthrax kernel. I've tried updating the profile & prl. I have between 2-4 bars of 3g and yet it still gives me the webpage not available sign. I tried clearing the cache/ fixing the permissions. But the internet simply won't work. I'm in Maryland, between Baltimore and Frederick. What could the problem be? Maybe the phone itself is defective or Sprint's network died in my area?
I'd see if they're doing work i that area. I know in areas of Baltimore 4G is there, I believe. You could try using build prop tweaks ect for signal if you wanted.

Misery loves company.
The 2nd post is a thread I started regarding the same problem. The first post is to a thread I thought could help me. I tried some things mentioned in there but none of them worked. Then someone posted in the thread who is having the same problem.
Here's what I've been running into and what I tried. I am on FreeGS3, Anthrax kernel, and recently updated to MA6 when I started having problems. I use a battery saver so my internet connection turns off when my screen is off. I started noticing a week or so ago that when I woke up my phone, the 3g icon would appear but only the up arrow flashed. The download arrow wasn't doing anything. I would toggle it off and on and eventually get it to work. I'm in the Raleigh-Durham area and we are just starting to get LTE. My 4G works whenever I go through 4G areas and my wifi works. I have restored a working backup, wiped my phone, flashed back to stock unrooted, called Sprint (they refreshed my signal and had me do an OTA activation), manually changed my PRL, upgraded to MA6, updated profile (when I could get it work).........and I think that about sums it up. The one thing I've noticed is my phone works flawlessly when the network mode is set to CDMA. At this point I'm clueless. I really don't think it's a phone issue because 3g works on CDMA. It's like when the phone is set to CDMA/LTE and it doesn't have an LTE signal, it doesn't know what to do. That up arrow flashes in such a rhythm that it's like the code is stuck in a loop.
