Exclamation [BUG] CM9/CM10 Data connectivity bug - unFIXED, it seems

The connectivity bug appears to be back again since the 2 Nov CM10 update - can others please confirm this?

This bug has been squashed, thanks to a hack by SlugZero, many thanks! The fix has been incorporated in Quarx' builds, from 12.09

Many users have confirmed the data connectivity bug (in CM9 and CM10) and others seems unaffected. The purpose of this thread is to try and characterize the problem, to see if there is a common setting that increases the likelihood of the data disconnects.

Please provide the following information if you are faced with data disconnects (APN info found under System Settings > More…> Mobile Networks > Access Point Names) :

Type of service provider: Normal /Virtual
Cell reception area: Good/Average/Bad
Data type problematic: 2G/3G/HSPDA/All types
Access Point Names - APN: internet/URL
Proxy: IP address/URL/blank

If you have any info to add or think there might be something else causing the problem, please say so in your post.

Hopefully we can use the gathered info to get this bug squashed

EDIT 06-07-12

Here’s what I’ve experienced so far:
1. Having only one APN in your APN list is better, I delete unnecessary APNs.
2. Selecting only 2G or only 3G is better, I leave my phone on 3G and switch to auto when there is no 3G coverage. - Edit 08-03-2013
3. Forcing your phone to work on a specific network is better, if you have the option to roam on another network, that is.
4. Older networks seem more problematic than newer networks (just a hunch).
5. Some sim cards can be problematic, I recently bought a new sim card and it improved my connectivity 10 fold, but I still have the odd disconnect if I disobey the rules above.
The dropout seems to be caused by an incorrect handover from cell tower to cell tower, or network to network, or one network type to another, so by limiting these changeovers, you limit the chance of dropouts. My connectivity is pretty much “perfect” now, although it would be great to leave everything on auto without concern. If you want to do that, you could install Connection Checker, by Jeremy Chase. This app toggles Airplane mode if it detects a data disconnect. I don’t use it anymore though.
I’m on FuZZ_’s 30 June CM9+ build at the moment.

OK, I'll get the ball rolling:

Type of service provider: Virtual
Cell reception area: Average
Data type problematic: All types
Access Point Names - APN: URL
Proxy: IP address

No problems, when I uses 2g only

Geramn Forum, where they discusses the problem too.

Are there any Custom Roms without this problem? I have this problem with CM7 too.

I think there are two levels of this problem... for virtual networks all data types are problematic, for regular networks like yours, 2G only is stable. I'm hoping to gather enough info to prove this.


I don't think all custom roms are affected, I have no problems with WIUI when Auto APN switching is turned off (a feature that doesn't exist in CM7 and CM9)

I have to switch off and switch on wifi and cell data every 5 minutes to get it work. It just stops working. If I download any kind of data it freezes after by 3 MB.

Wifi works fine just on CM9-NIGHTLY-120516-Defy+.zip
cell data doesn't wokr just on CM9-NIGHTLY-120529-Defy+.zip

Please try the following:

Go to your Access Point Names and open the active APN
then click on menu and save the APN
Let us know if this helps (it has made a significant difference for me)
All non-active APNs should be deleted by hitting menu, delete APN

This will probably have to be repeated after every reboot (if it helps)

I'm using Tasker to reset the "mobile network", if I reset "APN" or "mobile data" it doesn't work.

The free Market app Connectivity Checker by Jeremy Chase helps hugely to restore connectivity when it drops out by toggling airplane mode for a split second. If you're on the phone when it checks it skips the check, so no chance of cutting off the call.
