I face the same problem?

are you with Orange?

Theres some videos out of the browser working in 3G and it seems fast, but the dificulty in obtainning 3G is something i havnt heard of yet :|

Fixed with a restart

I've been roaming outside with mine today, got a HSPDA connection constantly it was very fast on O2.

Yes, orange. I've just changed from GSM only to GSM or WCDMA and it's picked 3G up again, maybe out was as simple as that...

Another silly question. Is it not connected by usb to a pc? When it's comnected as external drive it won't show on th desire.

Today seems to have been fine... 3G and H most of the day.

Check if your wifi uses channels 12 to 14 by any chance. Those are not public domain and HTC phones won't connect to them. Change it to something between 1 and 10.

thanks VERY much you just saved me from throwing my DHD through the window, my wifi was so unstable it was impossible to use , changed to channel 8 and hey presto reliable wifi
cheers

3g problems after 2.3.3 update

I guess im not the only one having problems with 3g after the 2.3.3 update. 3g seems to turn itself off after not being used for a little while, the only way i can get it working is by turning mobile networks off then on again. i so hope they fix this and other bugs that have arisen since the update.

I'm using custom rom and everything is great (Ardhd). Try changing the network mode to stay on 3g at all time, thus it will not switch between 2g and 3g.

everything is switched on as it should be, same as before the update. checked to see if i had done wot you said and was already on. i believe there have been issues with 3g but not really had the time to search the threads

3G works like on-demand

Hi All,
I have been having problems with my S3 for some time now.
HSDPA. Sometimes it works and sometimes it does not. It works as if it was set up to work on demand.
Where could it be set up like that? I have checked every menu and cannot find anything.
Help much appreciated.

I don't understand, do you mean it keeps switching between 3g and H when you ate using it and not using it?

HSDPA works and in a few seconds stops. No data at all. Then HSDPA works again for a few seconds and so on. No pattern or anything. I tried to keep it running by keeping Skype work, but it would disconnect from data completely again. It is connected to HSDPA network and I can make calls over that, but no data.

Sounds like your being ping-pong'ed between antennas.
Usually flashing a eastern modem (I can recommend the ZN... ones) should fix it since they are optimized for large cities which have this issue.
Also, having a proxy server configured in the APN settings may cause this issue if it's overloaded and causes connection resets.
If you have one configured, write down the settings(in case you need it ) and try removing it.

Some good ideas.
Heading to the modem collection thread.
No proxy in APN.
An interesting thing is, that I went to another city a few hundred km away and everything was ok, so I thought it was the phone and it started working again. I am back in my area and it is happening again. The only thing is, no one else is having these porblems, even people using S3.
EDIT:Just fashed ZNLH3 using CWM and will start testing. Right after starting the phone, there is no data active.
EDIT2: I forgot to mention, that when I switch to GSM only mode, EDGE works just fin, no disconnects at all.

Try fast dormancy apps from play store and disable it.
The switching between hsdp and 3g is not a problem. It is a technology to preserve your data usage when you are not using.

There is no problem switching between 3g and H, there is a problem with switching between HSDPA and NOTHING.
ZN modems did not work.
Will try fast dormancy, the setting was not available in the ZN modem under *#9900#. Will try LH1 and Pay Store.
EDIT: FD switch installed and FD disabled. Will do some testing and report back. Working on LH1 modem now.
If you still have suggestions, they are more than welcome.

I am having exactly the same problem on 3UK... the data connection just stops working for no apparent reason

For another test, download a terminal emulator app from play store and then ping google.com or any other site in a loop ... See if you get breaks ...
Keep phone still ... Then try same with moving it around your house ...

Must be something with the phone, as I disabled FD and data connecition is gone again.

My problem is that my data does not work when on 3G but it works when on H+.

I don't suppose you have the I9300T by any chance? I had this problem with the I9100T (S2) and it was a pain

Nope, I9300 here.
Will also download DLI1 tonight and see if flashing that changes anything.

Position has not effect, it happens wherever I am.
I will try with ping and see.
EDIT: PIng seems to make the connection persist. Will keep it running and see.

Been running ping for over an hour now and no data cutoffs. Means there is something that keeps disconnecting me.
How do I find out what and fix that?
To answer my own question:
I instaled DLI1 last night and so far in almost an hour not a single data blackout!

I was wrong blackouts still happen
Using DLI1 and FD switch, it now works much better, but there are still blackouts.
I will look for the GSM Monitor software and see if that can help me identify the problem..

problem is your location ur phone is jumping between 2 bad signals/towers and one of those towers does not have 3g on it only 2g
I say this because I have same problem at home. certain areas of house amazing 3g reception others .ir does not work and ye so .ir flicks between them and I often eexperience "blackout" . .signal says on H but no data throughput.
try downloading gsm monitor from play store will show u how string signal is and which tower it .
hope this helps
really hope u find a fix ( I've just accepted it )

I'm pretty sure that disabling fast dormancy will fix this. I've seen people with that problem before and was fixed instantly. Search the forum for the fix. There is a file you download to insert that will fix it.

I have no choice but accept it. Will use monitoring tools to see if you are right, it sounds quite a good explanation.

FD is disabled and it is still happening.

Did you try enabling wcdma only mode? Settings-more settings-mobile networks-network mode.
That might work by forcing it to stay on 3g/h+

Of course, I have had it set up like that since the beginning.
Remember that my problem is not with constant switching between HSDPA and EDGe, but with switching from HSDPA to nothing.

[Q] no network signal when phone is locked (stand by)

Hello.
My galaxy s4 4g i9505 is not getting any signal when the phone is locked. When i unlock the phone it gets the signal back to normal
It happens after I installed omega ROM 13.2. I had omega 12 and updated without wiping.

In Connections/ More Networks/ Mobile Networks/Network Mode choose GSM. You can choose LTE if you want but unless you are in an area that has non-stop LTE coverage, you will face the following bug: when your screen is off, it will lose the networks and stop mobile data. That wont happen when the screen is on and its really fast. So the solution would be to have the GSM option ticked and that way you still have mobile data even with screen off

Ok, it works, but if I select only GSM I have no 3g connection. And if I select GSM/WCDMA the problem reapears.

I have the same problem.
I tried all radios and the problem persist.
Everything works fine on google editon, but I have to say that samsung roms are much usable.
Solution:
Do not use roms based on mj7, use roms based on mj5 or go back to 4.2.2
I have tested all radios many kerneles with many mj7 based roms and always had this problem.
With mj5 based roms and rom based on 4.2.2 android everything is alright.

Nop. That doesn't work either. It still drops data connection if you set phone to 4G/3G/2G, and you move with your phone on deep sleep to a low 4G coverage area. It gets connection back as soon as you turn on the screen...
Any other solution so far???

I don't have any of those.

I'm having this issue too after updating to the most recent CM nightly. I thought it was the nightly, but after after multiple wipes and even different ROMs, I still seem to have this issue. My mobile network drops as soon as I put the phone to sleep. When I turn on the screen, sometimes it connects automatically, sometimes I have to airplane mode and back. If I change my mobile network to 2G (gsm), it stays connected. Wifi always stays connected it appears.

Mobile Internet connection

Hi, sorry for disturbing, I have a weird connection problem and I am pretty sure it is not the internal antenna... When i use the phone for Internet, mail etc etc.... Everything goes fine it uses a 4G connexion and I almost never have a problem, I do have a problem Sometimes when I am not in a 4G covered area... Than i have to change the network modus to wcdma /gsm automatic because if I leave it on lte /wcdma /gsm the phone is jumping all the time between hspda /h/edge gprs... And this goes fast like that that connection fail... This problem stops when i change modus than I get a stable 3g connection.... A little bit disturbing but Okay..... The biggest problem is that I m always connected with my messenger services like for example WhatsApp.... When i have the phone in my hand no problem at all.... But when he stays on the table or in my pocket it is kinda weird.... Sometimes I don't recieve my messages and than suddenly when I pick up my phone I get like ten messages in once starting from like half hour before.... All this started like three weeks ago, network provider say there are no network problems, I didn't drop my phone or something... Internet connection is just acting very strange lately and this started before I updated to the official 4.4 rom and didn t change after...... I also have to tell that I don’t have problems at all with phone calls or texts messages..... It's just those two mobile Internet issues.... Since i m only good for using the phone and don't know nothing about the technical parts or something... I wanted to ask the question to all of you experts.... And wanted to ask for help and if possible a solution? I want to thank you in advance and hope you guys can help me soon.... Kind regards...

Try different modem perhaps?

Hi thanks for answering.... Tried everything.... Still same two connection problems..... Only thing I didn't do yet was a hard reset.... Could this problem be caused by an application or a bad uninstalled application? Thanks in advance

Hmmmmm, highly unlikely from my point of view, but however there could be some apps locked into 2G or 3G or 4G connection.
Try how clean system doing, if it's same, consider it a hardware problem which there is nothing we can do about it...

samsung s4
i am having network issues
wifi works good
2g works good
3g/4g doesnt work at all no signal if i select these networks
is it a modem issue or kernel issue
