Hi,

Usually i have wifi enabled permanently, as i have coverage at home, university and t-mobile hotspots. But my nexus sometimes does not get a working data connection if i disable wifi or come back from flight mode. Icon shows reception and 3G/H/H+ but stays grey. I can't access any internet services like mail,http...
If i reboot the device, everything is fine.

Any ideas ?

Latest (-3days behind max) CM10 with stock kernel, XXLF1 baseband, tmobile germany

P.s.: tried to search with google, found nothing. Currently the nexus is my only internet-capable device, so i am sorry if repost...

Try toggling airplane mode?

Same issue here. Get random signal losses and afterwards no data until reboot. I've experienced this with other Roms as well. Toggling the airplane mode sometimes help for data recovering.

Try setting your minimum CPU above 500 Mhz...

Maybe toggling wifi helps (sometimes)

I have exactly the same problem on galaxy s. The status bar shows mobile network connection, but the symbol stays grey, and connection is not there. Reboot is the only safe way to solve that. Sometimes toggling airplane mode helps, last time toggling wifi helped.

Changing APN seems to be helpful. Someone that looks good with the current provider.

almost same issue for me...
but there is some weird difference...
I have a GSM Galaxy Nexus latest radio, consistent RIL and latest CM10.

I lost data suddenly while browsing.
I can see blue signal with 3G, start browse and it change to H/H+. No problem until now but, when data returns to 3G, all further requests stay "pending" for a while (phone call is not working in this state!!!!). after a minute.... CRASH, all signal lost. Something like a reset.

even toggling data does not work... I simply have to wait that the phone decides to work again.

I'm from Italy, carrier is Vodafone. Someone with some hint?

thanks!

It's the correct APN, did autoconf OTA.

Because on earlier builds of some AOSP ROMs, the radio had a tendency to go to sleep and not wake up when the frequency dropped too low. The common fix at the time was to use a higher number for the minimum frequency...

I was looking up the answers to this same problem. When I'm staying still my internet is fine but when I'm driving down the road I lose signal. I did a google search for "cm10 losing data connection". This is a "normal problem" it is caused from changing between 3g and LTE 4g. I'm still looking up solutions to this problem.
