My wifi connection is better since the update. You may want to check other things like your router, etc. Try the Wifi Analyzer app available in the market to help you troubleshoot.
wifi not connecting unless turn off then back on?
I'm new to this but Im having wifi issues as well. No matter what wifi i go around i have to turn off then back on my wifi for it to connect. Does any body had this issue or know what might be wrong?
Do you have SSID broadcasting enabled? My Infuse wasn't able to connect to a hidden SSID after the update.. Had to broadcast and enable security to get it to work.
Got the phone today. Wifi issues right off the back. Can't even get past 128kb. lol.
Phone is being returned.
Why was this bumped....

When my phone shows the H symbol for network, it works well, but when I'm not using the network (no traffic), it falls back into 3g and gets stuck on upload. Occasionally, H service will come back, but often it won't. I have found if I turn the screen off, H service is restored.
I have had this problem for months now. I have a i9020a. Currently I have CM9 April 8th nightly installed, using the i9020AUCKJ1 radio. I just got done reverting to the stock build recently released from Google (IMM76D, I think), then upgrading to CM9.
No matter what I've done, nothing has worked:
1. reverting to stock then upgrading to a custom rom (Team-Kang, CyberGR, CM9, etc);
2. trying different radios;
3. opening phone info (*#*#4636#*#*) and changing it to GSM auto PRL as well as setting the band to USA;
4. making sure the APN is correct;
5. restoring the IMEI backup;
Any ideas what the issue could be?
H is 3G. Only active while data is being actively sent/received and it is actually feasible to use in your current area. Also, are you sure it is not only the animation that gets stuck?
Is there an actual problem, though? Is something not working quite right (data, sync, notifications, etc)?
It gets stuck on UMTS:3 (just keeps trying to upload) and won't work again until I turn off the screen and then it will usually revert to HSDPA:9.

you should download taskiller.. kill all app before you use your internet, i have same problem and always solved with that way..
hope this helping

While taskiller certainly kills most running processes, it does nothing to help my network connection.
On a separate note, my roommate has the same phone and his maintains a steady HSDPA:9 connection without ever dropping into a UMTS:3 connection.

The normal behavior of the phone is to use HSDPA while it's in need(download/upload) , when not in use automatically goes to UMTS:3
What ROM your room mate is using ? model ? radio ? network ?

You're talking totally rubbish ... Killing apps will not enhance anything and may even slow things down by needing more CPU power to open auto apps again...
I have expereinced the same issues with my 9020a on ATT. Sent phone to Samsung twice, changed SIM cards 4 times. Updated radios, now on 4.0.4 getting about 120 kbps download speeds while my other phone (work phone), iphone4s on att, gets about 5 mbps.
Call att, they credited me my entire months bill and offered a free galaxy note with a 2 year agreement. My thought is that ma' bell is just killing any unlocked phone or there are issues related to "LTE" rollout they wont admit to that is causing a disruption with 3.5G.
Anyways to the OP, you aren't alone. I too hope someon can help!
My roommate is using the same rom, CM9 (nightly from 3/29 though), radio is i9020xxkb3, network is also AT&T with same plan.
Watching the About Phone/Status on his phone, it stays on HSDPA:9.
My returns to UMTS:3 when not in use, but when in this mode, I get no network traffic at all. I will flash upload but will never download anything. Occasionally, H service will be restored, and I will get my network connection back.

why you're wifi on ?
I don't always turn it off when I go to work. Unless I'm traveling I usually leave it on.

To begin proper troubleshooting turn wifi off while you browseand report back
I experience the same connectivity problems whether I have the wifi off or not.

same problem bro
i am from the Philippines and i'm experiencing the same problem with my i9023. No connection when on "3G", connection resumes when "H" or "E" appears in status bar
I too have this problem it's annoying!!

When I leave a wifi network (physically), instead of the phone recognizing that it's no longer got a wifi connection and flipping to LTE, it thinks it's still on a wifi network.
The only way for me to get my connection back is to temporarily toggle wifi off. Both Wifi and LTE seem to work fine otherwise.
Anyone else experience this?
Very common bug. Hoping an ota comes out soon.

Appologies, my searches didn't turn anything up somehow. Need to take Google 101 again, I suppose.
Good to know I'm not alone with this bug.
Second day owning this device and love it so far, but day two has been rough. I am stuck on 3g. All of a sudden today my lte switched and will not go back. Iv'e rebooted, toggled airplane mode and data. Even pulled the sim. I live in a strong 4g area so that is not the problem. My buddy has a nexus and his is fine. I also have had great reception in areas I have always had problems, so not a reception issue. I called verizon and was told it is a know issue that is normally solved with a reboot. She said an update was scheduled for early September to fix the issue. The point of this thread is to find out if anyone else has had this problem, or found a solution.
Edit: After countless toggling I got it back to 4g, but it won't connect to the network. So my thought is that the sim card is trashed. Going to get a new sim card first thing in the morning.

Unfortunately I am also finding myself stuck in 3g. I have pulled the battery, installed a new ROM. Still working on it, not thrilled. Prior to 4g disappearing, it showed 4g, however I was unable to connect over it. I hope this isn't a hardware issue.

Did this work?
Just FYI, I have the SCH-i535 and am noticing similar behavior. I had a Samsung Droid Charge before the SGS3, and it stayed locked to 4G LTE in the same exact areas of my home. If my Charge did happen to drop 4G, it would always come back. But not with my SCH-i535. Once 4G drops it stays on 3G until I reboot the phone. So far, this is my only complaint about this phone.
It is very random for me. Im certain its a **** sim card. Right now its fine, but at any time it may get stuck on 3g. Also while at work the first couple of days it would hold a decent 3g signal, now its primarily on 1x. Once i replace the sim card I am hopeful for it to be fine.

I thought Verizon said that this was a known issue? I'm just curious as to why you would disagree. But if a new SIM does happen to fix the problem, please let us know.
Just a heads up! I have the same issue, but I can't get 4g back at all, which I thought stemmed from flashing CM9, but this thread is making me wonder now! I spent an hour on the phone with Verizon technical support and they said you will get a popup if the sim is the issue. They told me its the phone and they are sending me a new one. FYI you can try this code. *2767*3855# in the dialer to factory reset the phone ( can do the same in recovery ofcourse), but you HAVE to be running STOCK UNROOTED! Some people have had luck with this "resetting" the radio I guess. If this doesnt work, might as well call them and get a new phone coming. TRUST ME, I believe I did everything I could think of before calling them, except taking the phone apart and pulling a new radio out of my ass!! Lol
I'd just return the phone and get a new one if possible.
They did tell me it was known issue. Its just weird how random it is. I am hopeful it is either the sim card of a software issue. I hope it is not a hardware issue. I would rather not have my phone replaced as I just put a new screen protector on. Also to those getting a replacement, is it brand new or a certified like new device?

I did read in another forum that the replacement phones are coming out with a baseband update. I'm guessing that we will probably need to exchange our phones...or be patient for the OTA. Hopefully it won't be too much longer. Incidentally, I just did a factory reset and 4G now appears to be working. Time will tell...

I also flashed CM9, and I am fairly certain this was the cause of my problems. Nothing I did would make 4G work again.
Other 4G VZW devices seemed to work fine at the same time(I have an ipad3 for work, POS).
I didn't mess with it for a couple of hours while running errands, then all of the sudden it was working again. Been fine ever since as far as I can tell. It would be nice to know what exactly is causing this, but for now I'd caution against messing with cm9 .
Hello everyone,
I hope someone can help me because I am going crazy with my Optimus 3D My device constantly loses the 3G connection and so I don't get any notifications about new e-mails and Whatsapp messages. The icons for network strength turn white and even sometimes that happens with the wi-fi icon. I already tried rooting the device and installed a custom rom but I still have this problem. The problem mostly occurs in the office I work in as 3g and network reception is very low here. I see that the device switches between HSDPA, GPRS and 3G quite often and then most of the time loses the internet connection. It also does not reconnect when I walk around and get to an area with better reception. Sometimes switching to Airplane Mode and back helps, but this is not a very handy solution. I am really clueless where the problem could be. I am here in Frankfurt/German so normally there should be no problems with the network (I am on Vodafone). The only thing I could think of is my SIM card, because I had an iPhone 4 before and had to cut the card to the micro SIM size and now use it with an adapter. Could this be a problem? Also the app 3G reconnect did not solve this problem.
Has anybody a clue what might be wrong with my device? I am already thinking about getting a new phone
Cheers,
Andreas
Does it do that when goes to sleep?

I don't know when it loses the connection, could probably happen when it turns the screen off or switches between network speeds (3G, GPRS, HSDPA). It really is a problem for me that it does not get the connection automatically back. Currently it shows almost full network reception, the "G" icon with both arrows underneath (only the left arrow pointing up turns green from time to time), but it has no internet connection. I sent me a mail to my google account via my office PC haöf an hour ago, but still no message on the phone, that there is new mail
Just try a new simcard... my guess is that it will solve your problem.. could be worth the couple euros ..

I had similar Problems with O2 in Bremen.
That happens if the phone loses the 3g(h+) signal, turning of the data connection, and let that reconnect is enough, no need to turn on airplane mode than.
Try flashing the newest baseband version, and try the prometheus rom + kernel. I still notice that the same problem happens, but it reconnects again after losing it now, and i rarely notice it that way.
Maybe you could tell us your android version, and baseband version.

I had a similar problem when I used GB roms without upgrading my baseband.

Hi everyone,
thanks a lot for your answers. I have the newest firmware on it V21E and baseband is L6260_MODEM_SIC_01.1042.00. Problem is that it does not automatically reconnect when it loses the internet connection. I had this problem again the whole day. When I left the office for lunch it did not reconnect, so again I did not get the newest e-mails. Probably I will really try another SIM card with a different network provider. I never had this issue with my iPhone... Thanks a lot for the advices, hopefully something will work. Otherwise I need to get a new phone :/
Cheers,
Andreas
For me the 3g data service goes as it likes but to reconnect i have to restart the my phone. Tried many roms as well as kernels and finally using acura 3d Max 3.1 with titan kernel solved the problem. It doesn't give up 3g connection but if i switch to edge and back to hsdpa again i have to restart. Barry also lasts and have overclocked to 1.2 ghz
In the Dailer APP dial *#*#4636#*#* Phone info Scroll Down just above the turn off radio button Change from WCDMA Preferred to WCDMA only
Good morning (at least here in Germany it is morning *g*),
got me a new SIM card with a new provider yesterday evening and so far it seems to work fine in the office. I hope it stays like this, then the problem would be solved *phew* Thanks a lot for all your help!
Cheers,
Andreas
