Do you mind testing what I posted on previous page?

The problem seems to occur most for me when leaving a Wi-Fi signal area after being on Wi-Fi for a long while. Immediately afterwards, the 3g/data signal goes haywire, disconnecting and reconnecting several times over a few minutes of use. Things seem to work better if I manually disable Wi-Fi before leaving the house; I still get occasional drops, but only once every few hours, which really isn't too bad. (EDIT: Never mind, the problem came back.) This leads me to suspect that it has something to do with transitioning between Wi-Fi and 3G, but of course that's just a guess.

Undercover, how's that new setting (LTE/GSM/CDMA AUTO (PRL)) working out so far? Also, I don't think you mentioned whether your data drops were "permanent" (i.e., requiring something like toggling airplane mode or rebooting to fix) or temporary (data drops, then reconnects itself after a little while).

EDIT: I was able to grab this from logcat around the time a data drop happened:

Code:
W/Smack/Packet( 1065): notify conn break (IOEx), close connection
D/ConnectivityService(  541): handleConnectivityChange: addresses changed linkProperty[0]: resetMask=1

D/overlay (  163): FROM_STATE = OV_BYPASS_3_LAYER TO_STATE = OV_CLOSED
D/ConnectivityService(  541): handleInetConditionHoldEnd: net=0, condition=0, published condition=0
D/ConnectivityService(  541): handleInetConditionHoldEnd: no active default network - ignoring
D/Tethering(  541): MasterInitialState.processMessage what=3
I have no idea if this is helpful or informative at all ... perhaps someone more knowledgeable than me would be able to make some sense of this , or tell me what information might be more useful.

WiFi off the whole day, H or H+ connection, in an area with full coverage.
Simply no connection to the internet. No signs of loading anything (no up/down arrows). Bar still blue and shows full connection. When trying to load pages in a webbrowser, it just sits there and loads forever.
Airplane mode seems to be bugged too if that occurs. Disable and enable the data connection doesn't work either. The H/H+ sign doesn't even go away.
I've yet to test if calls are still working in this situation, or if it's just the internet connection.
Only a reboot seems to fix the problem.

CyanogenMod nightly (1/3/2013) with CM kernel.

Sounds a little different from what I'm experiencing. My 3g/H symbol actually disappears and the bars go grey. I remember reading that there was a bug in a CM nightly a few days ago that caused data connection issues - could that be your problem?

Same here.

No, not really my friend. Still hit and miss. I'm messing with wifi settings now, hoping for a lucky guess.
I'm here, just reading more that posting. Keep throwing all the info in that you think is connected to that, we might hit a jackpot by an accident

Thats the same issue I'm experiencing, 4.2 Aokp with stock kernel. I also experienced this issue when it was in its vanilla state.

Oh, completely forgot.
To get radio related logcat
Get terminal emulator app
type
Code:
su
logcat -c -b radio
that will clear logcat. Now try to replicate the problem. Once you do (try to do it asap to keep log small) type

Code:
su
logcat -b radio > /sdcard/logcat.txt
That should save it on internal memory root
