What steps will reproduce the problem?
1. Not using the phone for a certain periode of time.
2.

What is the expected output? What do you see instead?
I have the "H" icon in the notifications bar showing that I do have a data

off and on to get real data connection.

No

Unofficial CyanogenMod 9.0.0

Same problem, and even more - after the night I have to restart the phone to 
get data connection back

Please try alpha2 and report back.

http://review.cyanogenmod.com/#/c/16827/ <<< This could be the fix for it.

That was the wrong change, there was one for the ril socket.

Well, there is no reproducer for this. It happens to me too from time to time.

still have to restart using airplane mode

I need logs if possible. This happens only rarely.

My guess:

You have a connection and everything is working. After some time it happens 
that you don't have any reception but something tries to access the internet 
and this stalls the data reconnect.

It is probably an upstream ril bug.

Hi Andreas,

Loved your Comment #8 ;). See "How to ask smart questions the smart way" by ESR 
(http://catb.org/~esr/faqs/smart-questions.html), you'll probably enjoy the 
read.

Enough off-topic.

Re. the issue, the HTC Chacha builds are also suffering the same issue.

User dapaua at XDA made this contribution, providing a script to restart data 
every 10min, so at most the data would be unavailable for 10min. I guess the 
same could be achieved using Tasker.

Not a fix, but at least a workaround so people suffer less of the disconection. 
I wonder if it's an issue only affecting us, because when I was running CM9 on 
my Defy I had the same issue several times a day, reason for which I got back 
to CM7.2.

I'm wondering also if it could be improved maybe by changing some ril 
propertiesd in build.prop.

I think it is a bug in rild, but I don't have the time to study the code right 
now. With some luck you find something in the radio logcat when it occurs.

In fact, when I switch between 2G and 3G, I need to turn off and on mobile 
data. CM9-alpha5. Same problem occurs randomly when I don't do anything with 
the phone. And the 'E' or 'H' sign sometimes disappears when the device is 
connected as a USB modem, thus connection is getting lost. In the last case, it 
takes only to switch fly mode on-off, no other way to get the data connection 
back.

I'm running in the same issues from time to time but wasn't able to find the 
bug yet. We need a log with an error messaging giving us a hint what's going 
wrong.

GoogleCodeExporter commented 9 years ago 
it's really easy to reproduce if you have the toggle 2g/3g button enabled. 
leave mobile data enabled and just change between 2g and 3g, if you don't 
restart mobile data, you cannot connect once you switch.

Then please attach a logcat reproducing the problem.

@comment #15. That error is different. They are two differents erros. 1. Toggle 
2G/3G and 2.  Not using the phone for a certain periode of time = 3G loses.

The same problem, even after using alpha 7

Happend once with alpha 7, after some time, i picked up phone, couldnt activate 
internet even though it was showing on  APN swich widget it is on. tried 
enabling, reenabling it, didt work. Restarted phone, worked fine. I guess its 
random.
Oh yeah, I use juice defender on aggresive, but my battery was 80% full (dunno 
if it makes any impact on this bug)

I have the same issue. Connection is lost after some time. cm9-rc2-alpha7.
Log is attached. In the beginning data connection works fine, but then on line 
479:
E/Gmail   (18330): IOException: Unable to resolve host 
"android.clients.google.com": No address associated with hostname

This problem annoys me very much, so I'd like to help in some way. What can I 
do to help?

Same to me with alpha9. Seems to be that you loose the default gateway when you 
change from one antenna to another. Every time I loose the data, I go to the 
shell and with ip route show I can confirm that no route for rmnet0. When I 
have data I got the route there.

Original comment by manolopm on 3 Jan 2013 at 9:32

GoogleCodeExporter commented 9 years ago 
Another clue, it loose the route because the rmnet0 link status goes down.
